Full textAbstract:
Traumatic brain injury (TBI) represents a significant and growing type of disability in South Africa. Coping with the impact of traumatic brain injury is one of the most difficult tasks that can confront a family, and family members experience a wide range of needs as the injured person progresses through rehabilitation. In South Africa, research on family needs following traumatic brain injury has thus far been neglected and rehabilitation resources are sadly lacking. For this reason it is necessary to accumulate knowledge about these families’ needs so as to assist with the planning of future rehabilitation programmes. The study aimed to explore and describe the needs of a sample of families with adult traumatic brain injury individuals in the Eastern Cape utilizing the Family Needs Questionnaire (FNQ). The research approach followed could be described as descriptive and exploratory in nature and was conducted within a quantitative framework. A biographical questionnaire and the FNQ were administered to a heterogeneous sample of 32 family members, including significant others and primary caregivers, of 16 adult traumatically brain-injured individuals, who sustained the TBI one to three years previously, and who underwent rehabilitation treatment at a private rehabilitation hospital in Port Elizabeth. A non-probability, purposive, and convenient sampling method was used. Descriptive statistics were computed to determine the importance and the perceived fulfillment of the needs. The results of the present study indicated that all 40 needs were endorsed by at least half the sample as being important to very important. Furthermore, 52.50% of the needs were endorsed by more than two-thirds of the sample as being important to very important. The needs were rank-ordered according to their importance ratings and the 10 mostly rated as important or very important were identified. These 10 needs were endorsed by between 84.38% and 93.75% of the family members as being important to very important. Six of the important or very important needs related to health information, two to professional support, one to community support, and one to emotional support. The relation between various participant, traumatically brain-injured individual and brain injury characteristics and the 10 important or very important needs, as well as the 10 needs more frequently rated as met were investigated and found to either have a limited or varied relationship. The 10 needs most often rated as met were endorsed by between 43.75% and 56.25% of the family members. Six of the met needs related to health information, two to community support, one to instrumental support, and one to treatment decisions. The highest unmet need was endorsed by 46.88% of the participants and related to the need to discuss their feelings with someone who has gone through the same experience. Based on the findings of the present study, further research on family needs following traumatic brain injury is suggested. It is also recommended that the Family Needs Questionnaire be used to evaluate existing rehabilitation programmes so as to make suggestions as to how to improve them. The results of this study suggested that family members would benefit from receiving educational information material, as well as referrals to professionals for advice and support.

Full textAbstract:
Predominant theories regarding adjustment and adaptation from the 1960s to mid 1980 are examined. Medical literature relating to outcomes after traumatic brain injury is examined. The gloom in major texts is surprising. The lack of definition of the commonly used term ???long-term??? is discussed. The relative lack of research to guide advice about very long-term prognoses remains a major concern. There are a number of ways of defining reality. Some come from an observer???s view of a person???s life. Some come from the reports of a significant other in the life of the person with TBI. Others come from the words or writings of the person who sustained a serious TBI. Quantitative research excels at summarising data and reaching generalisations based on statistical projections. Qualitative research excels at telling the story from the person???s viewpoint, providing the rich descriptive detail that sets quantitative results into their human context. An opportunistic sample of people who suffered a very severe TBI in 1981 was traced and narratives of their experiences since their injury obtained, either written or converted to text from interview. The texts were analysed using a qualitative technique based on grounded theory. The results of the analysis, the fact that a variety of approaches were used by people to deal with their problems, possible reasons for negative prognoses, and the limitations of the study are highlighted. Possible reasons why negativity appears to pervade the thinking of some health professionals involved with people with TBI, and possible directions for the future in therapy and research are discussed.

Full textAbstract:
Maximizing recovery of function after brain injury is the goal for many neuroscientists and rehabilitation medicine professional alike. To further elucidate the neural mechanisms underlying compensatory changes in brain injury and to determine the possibility of enhancing these changes, three experiments are described. Experiment 1 looks at the effects of structured (skilled reaching) versus functional (enriched environment) training with and without FGF-2, a pharmacological intervention, as treatment paradigms for rehabilitation-induced recovery of function in cortical lesion adult rats. Experiment 2 examines the treatment effects of tactile stimulation to enhance motor abilities in postnatal day 4 rat pups sustaining cortical damage. Finally, experiment 3 explores changes in the cortical motor representation after cortical damage. Results indicate a marked improvement on behavioral testing combing FGF-2 and functional training. Tactile stimulation significantly enhances recovery of motor functions. Post-lesion cortical mapping reveals changes in the motor representation utilizing the adjacent posterior parietal cortex.xv, 127 leaves : ill. ; 28 cm.

Full textAbstract:
Computerized cognitive retraining is a technique for remediation of the cognitive and behavioral changes which follow a traumatic brain injury. The technique utilizes specifically developed computer software which builds on the basic foundations of intellectual functioning. While the injured patient is the target of treatment, the method appeared to have an impact on the patient's family as well. Families of patients who participated in computerized cognitive retraining initially appeared to have fewer difficulties with anxiety, depression, and family problems. They also appeared to be more involved in the patient's treatment than were similar families who had not had this experience.The experiment evaluated the secondary psychological effects of computerized cognitive retraining on the brain injured patient's primary caretaker in the family. The dependent variables studied were perception of family involvement in patient treatment, anxiety, depression and perception of family problems.Subjects were recruited from the outpatient case load of the Psychology Department of Fort Sanders Regional Medical Center in Knoxville, Tennessee and from a local support group for families of patients who have experienced a traumatic brain injury. The injured patients and family members participated in the retraining technique. A total of seventeen patient/family member pairs participated in the study.Subjects participated in either the experimental or control treatments. The experimental group underwent five sessions of approximately one hour in length. The patient and family member worked together during the course of the retraining. Brief counseling followed each session. The treatment group used an Atari 800 computer and Bracy's "Foundations" cognitive retraining software package ( Psychological Software Services, Indianapolis, Indiana). The control group was a waiting list, minimum contact group, whose participation was limited to completion of the pre and posttest materials.Family members in both groups completed pre and posttesting packages. These included: a demographic questionnaire, the "Problem Solving Inventory" (Heppner, 1982a, 1982b), the "State/Trait Anxiety Inventory" (Speilberger, 1983), the "Beck Depression Inventory" (Beck, 1961), and the "Scale of Marriage Problems" (Swenson & Fiore, 1982).The experiment utilized Kerlinger's pretest-posttest control group design (Kerlinger, 1973). Patient/family pairs were randomly selected from the available subject pool. Control or experimental treatment groupings were assigned by stratified random sampling. Data were analyzed by the use of two way analysis of variance with repeated measures on one factor. Throughout the analysis, a level of R < .05 was required to infer statistical significance.The results of this experiment did not support the effectiveness of computerized cognitive retraining as a specific intervention method for the families of brain injured individuals. The findings revealed that there were no statistically significant differences between the control and treatment groups on measures of perception of family involvement, depression, or perception of family problems. The treatment group experienced a statistically significant increase in state anxiety following the experimental treatment. The validity, generalizability and implications for these findings were discussed in light of prior research.Recommendations for further research in the area of family response to computerized cognitive retraining include replication of the study with greater numbers of subjects and more sophisticated evaluation and treatment methodology. It is also suggested that future research address the patient's cognitive level, the utilization of varied retraining protocols specific to the patient's level of function, and premorbid psychosocial factors which may influence the process of cognitive remediation.

Full textAbstract:
Doctor of PhilosophyPersons with acquired brain injury require continuing support and care in various aspects of their lives many years post-injury. Their care and support are mainly provided by family members. While respite is one of a range of critical support systems for carers and people with life-long disability, very little is known about respite in the area of acquired brain injury. The majority of the research on respite has been undertaken in developmental disability, mental health and in aged care, but there is no research to date about respite from the perspectives of the person with a disability, the carer and respite provider. There is also no research that examines these perspectives in the acquired brain injury literature. This study was aimed to address this gap in the literature by investigating respite from the perspectives of the person with acquired brain injury, the carer and the respite provider. It also examined the profile of respite services being provided in the Australian state of New South Wales as there had not been a comprehensive mapping of respite before. Survey methodology was used to gather information from persons with acquired brain injury and their carers who were members of the New South Wales Brain Injury Association, which is the peak advocacy association of people with brain injury. The same methodology was used to gather similar information from members of Interchange Respite Care New South Wales, which is a peak association representing respite providers in the state. The survey questionnaires were developed and designed after an extensive review of the literature, and were reviewed by experts in the fields of respite, disability and acquired brain injury. The survey questionnaire was also trialled on a sample of families. The survey questionnaires for the three participant groups shared several common sections, such as demographic information; factors influencing respite use; expectations of respite; and satisfaction with respite services used by persons or carers. The responses from the three participant groups were analysed and compared using logistic regression and descriptive statistics. The key findings of the study are (a) several characteristics or factors of the person with acquired brain injury and their carer were significantly associated with the use of respite, (b) there were several common factors that all three participant groups reported to influence respite use, and (c) there were several common expectations of respite among the three participant groups. Some of the characteristics or factors that were significantly associated with respite use included the severity of disability, the high level of dependency of the person with acquired brain injury, and the number of days spent in a coma. Common factors reported by all three participant groups to influence respite use included the stress level of the carer and the severity of disability. Factors reported to influence respite use appear to be consistent with the literature in developmental disability. There were common perspectives regarding the expectations of respite among all three participant groups, such as the need for trained and qualified respite staff; a wider range of respite services and more flexibility of respite service provision. The study also indicated a reported lack of sufficient respite for persons with acquired brain injury and their carers. Some of the findings of the study appeared to be consistent with the research literature on acquired brain injury; such as the majority of carers being mainly female; there is a reliance on informal networks for the care and support of the person with acquired brain injury; and the majority of the persons with acquired brain injury being male. The study also found that many respite providers in New South Wales had extensive experience in running a respite service. The findings of the study have important implications for policy direction and development, practice and service delivery, and research. In terms of policy direction and development, implications explored included: a flexible funding model that is responsive to the needs of carer and person with acquired brain injury, and adequately trained and qualified staff and volunteers play an important role in respite provision. Further research is required to understand empirically the benefits and quality of life outcomes over a period of time, such as what types and extent of respite are more beneficial for certain demographic profiles. The study highlights the perspectives of persons with acquired brain injury, their carers and respite providers. Respite is an important support system to enable persons with acquired brain injury to receive the continuing care and support from their carers. Respite in acquired brain injury is a new field that merits further research as it holds the potential for addressing the needs of people with acquired brain injury and their carers.

Memory impairment is an outcome of Traumatic Brain Injury (TBI), and associated with lower levels of post-morbid adjustment. This research isolated the memory impairment of retrieval deficit, and examined the efficacy of cues and mnemonics in remediating the impairment. Thirty-three male and female TBI survivors, 18 to 71 years old, were pre-tested for attention (COPY), short-term memory (SD), long-term memory (LD) and recognition memory (RS) employing the Rey Osterrieth Complex Figure Test (CFT), and Subtest. Sixteen subjects demonstrating a retrieval deficit were administered the post-test, with even random assignment into four treatment conditions: a control group (CONTROL), a group administered cues (CUES), a group administered mnemonics {MNEM), and a group administered mnemonics and cues (BOTH) (n = 4). A MANOVA revealed a significant effect of TRIAL (p5.05), no significant effect of TREATMENT, and no interaction. A power analysis indicated the lack of TREATMENT effect could be the result of sample size. Post-hoc t tests revealed a difference across TRIAL for SD and LO in the two experimental conditions which utilized mnemonics. The sample was divided into two groups according to subjects' level of functioning (HIGH and LOW). A MANOVA showed main effects for LEVEL for SD and RS, for TRIAL for SD, LO, and RS, and a LEVEL by TRIAL interaction for COPY (R

Full textAbstract:
Background: This longitudinal study explored the impact on the family caregivers caring for a victim of a moderate or severe traumatic head injury (THI). The study used both quantitative and qualitative method and involved data calculation at three times points: one-month post injury, six months post injury, and one year later. Study Population: The study population comprised 45 family caregivers aged 21 to 72 years old. Thirty-four of the same caregivers were followed at six months and twenty five one year respectively. Methods: Both quantitative and qualitative methods were used to assess the family caregivers. The quantitative dimension comprised the Psychological General Well•Being Schedule (PGWBS, Dupy, 1984), the General Functioning Scale of the Family Assessment Device (FAD-GFS, Epstein, Baldwin, &Bishop, 1983), and the Stanford Acute Stress Reaction Questionnaire (SASRQ, Cardem1, et at., 2000), as well as a range of demographic variables. The PGWBS and the FAD-GFS were completed by family caregivers at three times during the study, and the SASRQ was completed by family caregivers at Time 1. Results: Findings from quantitative method revealed that in the terms of the impact on family functioning, no significant differences were found between the initial stages of injury, six months, and one year post injury at the 0.05 level of significance. Especially in the initial stages of injury, family caregivers of both moderate and severe THI patients were likely to be at risk of developing an acute stress disorder after exposure to the traumatic event. However, the family caregiver's psychological general well-being showed significant difference among three times at the 0.01 level of significance. The qualitative findings showed that most of family caregivers gave the meaning of THI as causing disability and severe injury. The major sources of distress were financial problems and victims’ prognosis or reactions. These caused an impact on caregivers’ financial situations, psychological and health problems, and loss of social interactions. Family caregivers used both problem-focused and emotion-focused coping strategies to deal the traumatic event. The coping strategies and resources that caregivers used to deal with the THI were consistent with the caregiver’s way of life and culture. For example, they used religious coping mechanisms and belief in God or traditional medicine and local wisdom combined with the professional health care sector to help them cope. Conclusion: The results of this study provide insights into the family caregivers experiences, understand how they cope with the crisis event and the impact of THI on their health. Health policy and local government should pay attention and promote the family caregivers’ well-being and welfare to support the family caregivers during their take role as caregivers.

Full textAbstract:
Purpose: The principal aim of this project was to investigate the influence of clinical indices of injury severity and polymorphism of the apolipoprotein E gene upon the long-term physical, cognitive and emotional sequelae of traumatic brain injury and spontaneous subarachnoid haemorrhage. It was also intended to determine the extent to which changes occur in these sequelae beyond the initial six months post injury. Method: Sixty-two brain injury patients who had previously taken part in a neuropsychological assessment at six months post injury were traced and participated in a follow-up assessmens some 6-9 years subsequent to their injury. Separately, a group of 70 subarachnoid patients drawn from a consecutive series of neurosurgical admissions participated in a neuropsychological assessment at 14 months subsequent to their haemorrhage. In both studies, the assessment comprised a semi-structured interview and a battery of cognitive measures focusing principally upon memory and executive function tasks. A questionnaire including a range of standardised measures of anxiety, depression and quality of life was left with patients to be returned by post. Results: The ApoE e4 allele did not appear to influence recovery amongst these brain injury survivors, though there are suggestions that it may have an influence upon subgroups of patients. Amongst traumatic brain injury survivors, post-traumatic amnesia was a better predictor of functional or emotional outcome than consciousness based measures. However, consciousness based measures were more predictive of cognitive sequelae and low admission Glasgow Coma Scale was associated with continued improvement on information processing tasks. Other than on these tasks, there was little evidence of change between 6 months and 6-9 years post injury. Amongst the subarachnoid haemorrhage patients, Fisher Grade was found to be more predictive of subsequent Glasgow Outcome Scale and cognitive function than WFNS Grade or other clinical indices. Surviving aneurysmal patients had comparable levels of recovery to patients who had a negative angiogram. In both studies emotional sequelae, in particular anxiety-related difficulties, were found to be a principal factor in the functional outcome of some 40% of patients. Conclusions: Greater emphasis should be placed upon measures of post-traumatic amnesia as predictors of functional recovery in surviving patients. The use of an amnesia measure may also be warranted in studies of outcome following subarachnoid haemorrhage or other stroke. The ApoE e4 allele does not appear to have a strong influence upon functional recovery after brain injury across all patients, though it is possible that it interacts with other factors to influence recovery in subgroups. Greater emphasis should be placed upon the prevention and/or detection and treatment of mood disorders following brain injury. In the absence of intensive rehabilitative interventions, survivors of serious brain injury are more likely to deteriorate than to continue to recover beyond six months post injury.

This study investigated the relationship between the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) in a brain-damaged adult sample. The sample in this study was composed of 30 adult patients at two residential treatment programs who completed comprehensive psychological evaluations between August, 1986 and November, 1987. Each patient was administered both the WAIS-R and the SBIV as part of these evaluations. Data gathered in this study was submitted to Pearson product moment correlational statistical procedures. Significant correlations were found in the following pairs of summary scores: the SBIV Test Composite Standard Age Score (SAS) and the WAIS-R Full Scale IQ; the SBIV Abstract/Visual Reasoning Area SAS and the WAIS-R Performance IQ; the SBIV Quantitative Reasoning Area SAS and the WAIS-R Verbal Scale IQ; the SBIV Verbal Reasoning Area SAS and the WAIS-R Verbal Scale IQ; the SBIV Short-Term Memory Area SAS and the WAIS-R Verbal Scale IQ; and the SBIV Short-Term Memory Area SAS and the WAIS-R Full Scale IQ. Significant correlations were also found in the following pairs of individual subtest results: the SBIV and WAIS-R Vocabulary subtests; the SBIV Memory for Digits subtest and the WAIS-R Digit Span subtest; the SBIV Pattern Analysis subtest and the WAIS-R Block Design subtest; and the SBIV Paper Folding and Cutting subtest and the WAIS-R Picture Arrangement subtest. Directions for future research were also suggested upon review of the subtest correlation matrix and the descriptive statistics of data generated.

Full textAbstract:
This study utilized the Medical Symptom Validity Test (MSVT) and a set of standard neuropsychological instruments to determine the underlying construct of the MSVT that accounts for effort in mild traumatic brain injury (mTBI) patients by comparing/contrasting mTBI with dementia and an analog simulation. The results indicate that a common underlying neurocognitive construct (memory) exists between mTBI and dementia patients, which may account for poor effort as measured by the MSVT. Other underlying factors emerged for both groups, though they did not point to a common construct. This finding suggests that the overall effect of brain injury in neurologically impaired groups also impacts effort performance as measured by the MSVT. Similarly impaired performance patterns also emerged between mTBI and dementia groups in sub-groups that failed effort measures. Thus, failed effort tests may be a function of more pronounced deficits in these groups, rather than a function of effort. Finally, although similar effort profiles were noted between mTBI and analog simulators, the analog group was unable to mimic the neurocognitive effects of mTBI.

Full textAbstract:
The issue of effortful patient performance has been an area of clinical interest in individuals with minor traumatic brain injury (mTBI). Clinical attention to this area has increased largely because of an increase in the number of worker's compensation claims, injury-related lawsuits and/or insanity defense pleas. As patients are presented with the opportunity for secondary gain, the issue of optimum performance on neuropsychological measures becomes salient. In addition to neurocognitive deficits, there are psychological characteristics associated with mTBI including depression, emotional disturbance, personality changes, and other psychopathology. This study utilized the MSVT, a set of standard neuropsychological instruments, and the Minnesota Multiphasic Inventory-2 (MMPI-2) to investigate the relationships between effort, psychological characteristics, and neuropsychological functioning in individuals with minor traumatic brain injuries. The first objective of this study was to determine which psychological factors were related to effort in mTBI. The second objective was to determine if there were differences between groups that performed poorly on effort testing and groups that performed adequately on effort testing, based on relevant psychological characteristics. The results of the analyses supported the first hypothesis. Hysteria was inversely related to effort, and Mania was positively related to effort on one of five measures of effort. The second hypothesis was not supported.

Full textAbstract:
As a result of medical advancement and cultural patterns of Western society, traumatic head injury is increasingly a problem for the injured, their families, medical and social services professionals, and the community at large. Head trauma is remarkable because of the complex nature of the residual disabilities which include long lasting cognitive and emotional problems, social isolation, and family disruption. The purpose of this study was to re-examine the phenomenon of recovery after mild to moderate head injury using an ethnographic research approach. The data were based on the experiences of 21 disabled and their families in the community setting. The disabled represented a range of stages of recovery and severity of disability. The data was collected using three field work strategies: extensive semi-structured interviews, participant observation, and non-academic document review. After collection the data was subjected to thematic and content analysis, that resulted in the selection of themes that characterized the experiences for the head injured and their families. The themes for the head injured informants were: dead days, loneliness, and forgetting. The family members' experiences were represented in the themes: responsibility, vulnerability, tough love, gender differences, and reactions to the experience. Next the data were interpreted using five theoretical concepts from cultural anthropology: liminality, personhood, social labelling, sick role and double bind. In addition, the reflexive influence of the investigator on the research process was addressed. The trustworthiness of the ethnography was assessed in terms of credibility, transferability, dependability and confirmability. Several variables were found to be important to the long term outcome of head injury. These variables were: family directed therapy, double bind communication patterns, and lifelong recovery. Two other factors were found to be critical for the recovery of the head injured. These were economic disincentives to the return to employment and the importance of the social and family environment. In the final section the research and policy implications of the study were discussed in relation to management and service provisions.

Full textAbstract:
Hyperbaric Oxygenation Therapy (HBOT) has a successive history for treating very specific groups of physical conditions. Research by Neubauer and colleagues states that HBOT's ability to increase cerebral metabolism in the brain regenerates dormant neural tissue (Neubauer, Gottlieb, & Pevsner 1994). According to this research, the increase of cerebral metabolism levels restores mental capacity from the neurological insult. Despite promise, uncertainty exists as to whether this is a viable treatment option for people suffering from neural damage. The research results for this experiment will examine the effect of HBOT on cerebral metabolism levels in adults and pediatrics with chronic neurological problems. Fifty individuals diagnosed as having a neurological impairment whom met criteria for the study were analyzed from an archival data set. Criterion required chronic impairment, baseline SPECT, followed by HBOT exposures, and a post SPECT scan. Statistical analyses consisted of a Pearson correlation that examined pre-metabolism rates with total change, a Pearson correlation that examined total change and number of treatments, and a one way ANOVA analysis that examined cerebral metabolism change in patients under 18 and over 18. Results indicated change

Full textAbstract:
The development of emergency department medical interventions and the implementation of fast-transport trauma systems has decreased the rate of death resulting from traumatic brain injury (TBI). Without corresponding methods for long-term treatment and recovery, the prevalence of people disabled by TBI has increased, creating a growing public health problem. Investigations generated by physicians, rehabilitation programs, and social scientists, which attempt to associate standard measures of injury severity with outcome, leave unexplained variance in long-term functional status for persons with TBI.
The purpose of this investigation was to use persons with brain injury and their family members, to guide an analysis of the factors that foster successful recovery from brain injury. Three studies were conducted. In Study #1, the method for observation generated by Kurt Goldstein (1934) was adopted to conduct 20 case studies of persons who sustained brain injury. The Schema of the EsEx Couple (Maynard. 1992) was used to orient the investigation. The EsEx Couple Schema proposes that events in human life must be understood by considering the whole system of Person (Essence) in the Environment (Exchange), and the transactions that flow in a recursive loop from Person to Environment and back. Kurt Goldstein's Laws of Organismic Life (1934), a model consistent with that of the EsEx Couple, was used to evaluate the data. Strong patterns associated family and social networks, autonomy, and perceived self-determination with higher levels of recovery, and were used to generate a Model for Recovery.
In Study #2. the Motivational Analysis of Self-Systems Processes (Connell & Wellborn, 1991) was combined with results from Study #1 to generate a Development Model, and to build a survey which was administered to 248 persons with brain injury. Results (1) confirmed the model, indicating factors that contribute to recovery were hypothesized measures of Social Context, Perception, and Engagement; and (2) established a valid instrument, generated by persons with brain injury and their families, for measuring functional status.
In Study #3. results of the survey research were used to return to the case studies to consider where individual lives differ from expected patterns, and why. Deviations from expected patterns were explored to identify how individual differences operate to affect outcome. Recommendations for clinical practice include (1) directing interventions toward family as well as patient, as a method of enhancing the Social Context for the patient, and (2) using careful evaluation of each patient's idiosyncrasies to consider individual interventions.

Full textAbstract:
The primary objective of this proposal was to determine whether mitochondrial oxidative stress and variation in a particular mtDNA lineage contribute to the risk of developing cortical dysplasia and are potential contributing factors in epileptogenesis in children. The occurrence of epilepsy in children is highly associated with malformations of cortical development (MCD). It appears that MCD might arise from developmental errors due to environmental exposures in combination with inherited variation in response to environmental exposures and mitochondrial function. Therefore, it is postulated that variation in a particular mtDNA lineage of children contributes to the effects of mitochondrial DNA damage on MCD phenotype. Quantitative PCR and dot blot were used to examine mitochondrial oxidative damage and single nucleotide polymorphism (SNP) in the mitochondrial genome in brain tissue from 48 pediatric intractable epilepsy patients from Miami Children’s Hospital and 11 control samples from NICHD Brain and Tissue Bank for Developmental Disorders.
Epilepsy patients showed higher mtDNA copy number compared to normal health subjects (controls). Oxidative mtDNA damage was lower in non-neoplastic but higher in neoplastic epilepsy patients compared to controls. There was a trend of lower mtDNA oxidative damage in the non-neoplastic (MCD) patients compared to controls, yet, the reverse was observed in neoplastic (MCD and Non-MCD) epilepsy patients. The presence of mtDNA SNP and haplogroups did not show any statistically significant relationships with epilepsy phenotypes. However, SNPs G9804A and G9952A were found in higher frequencies in epilepsy samples. Logistic regression analysis showed no relationship between mtDNA oxidative stress, mtDNA copy number, mitochondrial haplogroups and SNP variations with epilepsy in pediatric patients. The levels of mtDNA copy number and oxidative mtDNA damage and the SNPs G9952A and T10010C predicted neoplastic epilepsy, however, this was not significant due to a small sample size of pediatric subjects. Findings of this study indicate that an increase in mtDNA content may be compensatory mechanisms for defective mitochondria in intractable epilepsy and brain tumor. Further validation of these findings related to mitochondrial genotypes and mitochondrial dysfunction in pediatric epilepsy and MCD may lay the ground for the development of new therapies and prevention strategies during embryogenesis.

Full textAbstract:
This project represents one of the foundation steps to a collaboration between the
Department of Human Physiology, University of Pretoria and the Nuclear Medicine
Department at Steve Biko Academic hospital.
Following the initial discovery of the surprising effect zolpidem has on patients in persistent
vegetative states in 1999 by Dr H.W. Nel - namely that zolpidem administration results in a
significant qualitative increase in brain function, to the extent that patients were able to once
again communicate and respond appropriately to their surroundings - much data has been
collected by both Dr Nel as well as the Nuclear Medicine Department of Steve Biko Hospital.
Over the course of twelve years SPECT scans have been carried out on patients of various
pathologies both before and after a course of zolpidem. To this day, both assessment and
follow up of these and new patients is still being done by the Nuclear Medicine Department
and Dr Nel. As this vast collection of data grows it has become increasingly daunting for a
single research team to consolidate all this information into a usable form and an outside
team has been deemed necessary to facilitate this process.
The primary goal of this study was to quantify the neurological perfusion changes following
zolpidem administration within responder patients. This was achieved through reprocessing
and semi-quantification of the existing SPECT scan records held by the Pretoria Academic
Hospital. Within the group of responder patients (n = 29), 22 patients (~76%) presented a
significant increase in perfusion within at least one lesion with a range of 4.5 - 46.1% (mean
= 11.9%). In opposition to this finding non-responsive lesion perfusion decreased with a
significant mean change of -14.5%. For both sets the p-value was determined to be <0.01.
Of all lesions measured (n = 85) 32% displayed increased perfusion after zolpidem
administration, whereas 30.6% presented with a perfusion decrease.
It was determined that only one lesion is required to respond to zolpidem in a positive
manner to facilitate positive functional improvements with a given patient. In a small minority
of patients post-zolpidem functional improvements seems to be connected to wide-spread
cortical changes as opposed to singular lesional improvements.
This study provides further evidence of zolpidem’s paradoxical action in a subset of brain
damaged individuals. Unique quantification of results allows for additional insight and
provides further understanding the physiological changes associated with zolpidem
administration.Dissertation (MSc)--University of Pretoria, 2014.

Full textAbstract:
Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents in the US. Children and adolescents who sustain moderate and severe head injuries are much more likely to evidence significant deficits in neuropsychological functioning when compared with children with mild head injuries. Information about the recovery process and functional sequelae associated with moderate and severe head injuries remains limited, despite clear indications that children who experience such injuries typically exhibit notable deficits in intellectual functioning, particularly during the acute phase of recovery. Thus, the present study was conducted to augment research on intellectual functioning in children with moderate or severe head injuries. To accomplish this, the study first examined the proposed factor model of the WISC-III in children with moderate and severe TBI. Given high prevalence rates and similar trends in cognitive impairment, particularly within the frontal lobe structures (e.g., disrupted cognitive flexibility and divided attention), the study also examined this same factor model for a group of children with attention-deficit/hyperactivity disorder (ADHD) and compared it with the model fit from the TBI group. In the second phase of the study, both the TBI and AHDH groups were evaluated to determine if distinct WISC-III index score cluster profiles could be identified. Lastly, the cluster groups for both the TBI and ADHD samples were validated using important demographic and clinical variables, as well as scores from independent neuropsychological measures of attention, executive functioning, and working memory. Parent reports of psychological and behavioral functioning were also used in an attempt to further distinguish the cluster groups. Study limitations and future research implications were also discussed.

Full textAbstract:
Neuropsychological rehabilitation following acquired brain injury is increasingly recognized as essential with the advancements in research evidence of its effectiveness, particularly as current estimates of disability following the most common forms of brain injury (traumatic brain injury and cerebrovascular accident) are so high. Improvements in predictive capabilities of researchers and clinicians are paramount in designing effective interventions. As many variables associated with outcome following brain injury are not controllable (e.g. severity of the injury, age, education), it is essential that rehabilitation programs design interventions to target those variables that are susceptible to amelioration. While personality factors have been shown to affect outcome in other medical illnesses, only a few studies have examined the influence of personality on outcome following neurorehabilitation for acquired brain injury. The results of these studies have been mixed. This study used the Millon Behavioral Medicine Diagnostic (MBMD) to predict outcome as measured by the Mayo-Portland Adaptability Index (MPAI-4) following brain injury rehabilitation in a heterogeneous sample of persons with acquired brain injuries (N = 50). It was hypothesized that specific coping styles scales from the MBMD (Introversive, Dejected, Oppositional), which are based on Millon's personality system, would predict outcome. Results indicated that both the Introversive and Oppositional coping styles scales accounted for significant amounts of variance in outcome beyond that accounted for by the severity of the injury alone (p < .001). In both cases, individuals with mild/moderate-moderate/severe limitations following completion of the rehabilitation program had significantly higher scores on the Introversive and Oppositional coping compared to individuals with more successful outcomes. The hypothesis that a dejected coping style would predict outcome was not supported. Implications for rehabilitation are discussed in the context of Millon's personality system.

Full textAbstract:
Introduction: After a brain injury there are often long term consequences impacting on QoL. However, this is a complex issue influenced by many factors. As someone recovers and adjusts it is likely that the way in which they evaluate QoL will also change. The theory of response shift suggests people will change the way they evaluate QoL in the face of changes in their life. The aim of this thesis is to investigate what influences a QoL judgement; examining the possibility of response shift. Methods: Quantitative and qualitative methods were used in 4 studies. These were a cross-sectional design utilising an individualised QoL measure (SEIQoL-DW); a longitudinal study utilising a ‘then-test’ approach; a cross-sectional questionnaire study; and a qualitative study using Interpretative Phenomenological Analysis. Study 1 (Ch.3) Results: Correlations between the QoL measures confirm the validity of the SEIQoL-DW; however, correlations were generally stronger for the simpler Hadorn Scale. There was little overall change in mean QoL when current and retrospective judgements were compared. There was evidence for a change in what areas of life were considered most important to QoL following injury. Study 2 (Ch.4) Results: Improvements in reported QoL between baseline and follow-up were small. A then-test indicates that any effect of response shift is small, and non-significant in the current research. There was also little evidence for reprioritisation or re-conceptualisation. Examination of other factors associated with QoL suggest that brain-injury specific factors (BIGI, RBANS) play a role in predicting QoL. Study 3 (Ch.5) Results: QoL was reported as worse post-injury on both Hadorn’s scale and the QOLIBRI-OS; a difference that was more pronounced on the QOLIBRI-OS. Differences were also reported in the importance of different areas of functioning. Change in QoL as measured by the QOLIBRI-OS was significantly influenced by disability as measured by the GOSE, emotional and informational support, and upwards social comparison. Optimism as measured by the LOT, but not upwards social comparison was a significant predictor of change on Hadorn’s scale; GOSE and emotional and informational support remain significant predictors. The GOSE, emotional and informational support, emotional coping styles and optimism were significant predictors of current QoL on the QOLIBRI-OS; and emotional and informational support and optimism were significant predictors of QoL on Hadorn’s scale. Little evidence was found to suggest that the factors proposed in Sprangers and Schwartz’s (1999) model of response shift have predicted relationships with QoL. Two candidate variables were studied: optimism and social support. However neither showed the predicted pattern of relationships. Nonetheless the study supports previous work indicating an influence of optimism and social support on QoL, and indicates that these warrant further study. There were systematic difference between current and retrospective ratings of importance of domains. The level of importance given to the areas of life defined by the QOLIBRI-OS is higher after injury than before, with the exception of “personal and social life” for which there is no significant difference. The areas of life chosen to reflect that which is measured by the GOSE (“work”, “close relationships”, and “social and leisure activities”) are rated as less important with the exception of “close relationships”. These findings provide further support for the idea that QoL domains are re-evaluated after brain injury. Study 4: This was an in depth qualitative investigation of the experience of recovery and adjustment following TBI. Semi-structured interviews and Interpretative Phenomenological Analysis (IPA) were used. Interviews were conducted with 4 men who were 3, 7, 12, and 18 years post injury. Main Outcome and Results: Themes emerging from the analysis were ‘Change: In Self and World’; ‘Reaching a point of realisation’; ‘Support’; ‘Adjusting to change/Coping with day to day life’; and ‘Participation, Goals and Focus’. These themes cover how participants felt both they and their lives had changed as a consequence of their injury; ways they went about coping and adjusting to changes; the importance of support; and the significance of social integration and participation in feeling satisfied with life. Summary and Conclusions: These studies provide evidence for response shift in different ways. There is little evidence for recalibration but there is some indication that reprioritization or reconceptualization may take place. Changes in how important different areas of life are before and after injury suggest that participants are changing the way they view and make evaluations of QoL. Factors identified as being important to QoL judgements were disability, social support (emotional and informational support identified in the questionnaire study and support in the IPA), upwards social comparison, and optimism. The IPA study suggests that functional outcome and participation are important after TBI; while also identifying ways of coping and providing an insight into the experience of recovery from brain injury. The different QoL measures used provides both evidence for their validity, but also evidence for the different conceptualisations of QoL that are measured by different instruments. The findings have implications both for understanding the QoL of the individual and for research on QoL after TBI.

Full textAbstract:
This thesis investigates the reading and writing of two patients with brain injuries due to cerebro-vascular accidents. Background tests show both patients to be moderately anomic and to have severe impairments in reading and writing nonwords. Investigations of the locus of impairment in AN's nonword reading showed her to have normal orthographic analysis capabilities but impairments in converting single and multiple graphemes into phonemes and in phonemic blending. The central issue studied was the role of lexical but non-semantic processes in reading aloud, writing to dictation and copying. For this purpose a "familiar nonword" paradigm was developed in which the patients learned to read or write a small set of nonwords either with or without any associated semantics. Both AN and AM were able to learn to read nonwords to which no meanings were attached but they could still not read novel nonwords. Both patients were unable to report any meanings for the familiar nonwords when they read them and there was no evidence that learning to read them improved their sub-lexical processing abilities. These results are evidence for a direct lexical route from print to sound that is dedicated to processing whole familiar words. It was also shown with AN that if nonwords are given meanings then learning is faster than if they are not given meanings. Experiments designed to test the hypothesis that nonwords are read by analogy to words found no support for it. Both patients have severe impairments in writing novel nonwords to dictation. As they can repeat spoken nonwords after they have failed to write them, this is not due to a short-term memory impairment. Despite their nonword writing impairments, both patients were able to write to dictation the meaningless nonwords that they had previously learned to read at the first attempt, and AN did so one month after learning to read them. Neither patient however, could write novel nonwords made by reordering the letters of the familiar nonwords. Furthermore, the familiar nonwords used spellings that are of a priori low probability. The familiar nonwords must therefore have been written using lexical knowledge. Tests of semantic association showed that the familiar nonwords evoked no semantic information that the patients could report. Function words dictated to AN evoked little semantic information but she wrote them to dictation significantly better than nonwords made by reordering their letters. These results are evidence for a direct lexical route for writing to dictation. Copying was studied both with and without a five second delay between presentation and response. AN was better at delayed copying of meaningless but familiar nonwords than she was at copying novel nonwords. She was also better at delayed copying of six-letter, bi-syllabic nonwords that she had been trained to copy than she was at copying novel nonwords made by recombining the first and second halves of the familiar nonwords such that these halves retained their positions from the parent nonwords. AN was better at copying function words than nonwords made by reordering their letters. She was also better at copying function words than she was at reading or writing them to dictation. These results are evidence for a direct lexical route for copying. AN and AM were both able to write to dictation nonwords that they had never heard or written before but with which they had been made visually familiar during a visual discrimination task. They must have used lexical knowledge to do so because the spellings used were of a priori very low probability. The creation of lexical orthographic information which can be retrieved from novel auditory input raises difficulties for current models and various possible interpretations are discussed. Finally, some of the possible implications of the re-learning abilities shown by these patients, for rehabilitation procedures are discussed briefly.

Full textAbstract:
The present study attempts to further define the neuropsychological characteristics associated with mild, moderate, and severe closed head injuries (CHI). The Dean-Woodcock Neuropsychological Assessment System (D-WNAS), a new neuropsychological battery, was administered to 119 CHI patients. The scores of the cognitive portion of the D-WNAS were then analyzed via cluster analysis in an attempt to further delineate neuropsychological impairment into more specific classifications occurring within types of brain trauma.Results suggested that the cognitive portion of the D-WNAS was effective in separating 4 subtypes within CHI, which are best interpreted as "profiles" or characteristics associated with "levels" of impairment. These levels of impairment were characterized by distinctly different subtest profiles, and were labeled as mild/high functioning, mild, moderate, and severe. The highest performing group, mild/high functioning, showed no neuropsychological deficits. The most severely impaired group was characterized by many deficits in short-term memory, visual stimuli, new learning, processing speed, visual-spatial abilities, abstract reasoning, attention/concentration, and remote memory tasks. A multivariate analysis showed that educational level was significant in differentiating between the subtypes and suggested that, depending on the severity of injury, educational level might also protect individuals from obtaining a poorer prognosis.From this investigation, the cognitive portion of the D-WNAS appears to offer valuable utility in identifying CHI patients and in further classifying their varied neuropsychological characteristics. Implications for diagnosing and differentiating between different levels or profiles of CHI was discussed.Department of Educational Psychology

Full textAbstract:
Children with a recent history of TBI often demonstrate impaired memory, which can be affected by impaired attention, processing speed or impaired verbal information processing. The purpose of this study was to determine if qualitative differences exist among the narrative recall of TBI patients that is not adequately accounted for by standard scoring methods. Sixty-six TBI subjects ranging in age from 6 to 16 were given the Wide Range and Memory and Learning (WRAML) Story Memory subtest and selected subtests from the Wechsler Intelligence Scale for Children - Third Edition (WISC-III). Mean elapsed time since injury was 53 days. Recall of the story on the WRAML subtest was hand-recorded by the examiner. A supplemental scoring method accounted for differences in length, errors, and disorganization. Comparisons were made to a randomly selected control group consisting of 16 hospitalized subjects between 7 and 15 years with no history of head injury, neurological condition or event. Findings suggest the WRAML Story Memory subtest is relatively robust in providing information regarding the quality of recall, with the exception of not accounting for the addition of erroneous details. Subjects with both cortical and subcortical injuries were more likely to add superfluous details to their stories. Results also demonstrated significant differences between the TBI subjects and control group in how well the stories were recalled, primarily in the order of details recalled and in retention after a 30 minute delay. Location was not a significant predictor of narrative organization. Although using this comprehensive supplemental scoring system a regular basis has practical limitations, hand-recording the narrative takes relatively little time and does appear to provide useful additional information concerning the nature of the child's verbal memory difficulties. Furthermore, the more knowledgeable the child, parents and teacher are about these difficulties and about remediation strategies, the more likely the child will have a successful learning experience upon return to the classroom.

Full textAbstract:
Pharmacological interventions to treat Human Immunodeficiency Virus (HIV) with antiretrovirals (ARVs), have dramatically improved the survival rates of HIV positive children maturing into adulthood. However, HIV-associated neurocognitive decline still persists in the era of ARVs. Within the framework of brain plasticity, a number of researchers have begun to assess the feasibility of cognitive rehabilitation therapy as a complement to ARVs to reverse neurocognitive decline as a result of HIV (e.g., Becker et al., 2012). Only one study has been conducted in South Africa, by Zondo & Mulder (2014), assessing the efficacy of cognitive rehabilitation in a paediatric sample. The current research builds on the above mentioned study by implementing an experimental approach to examine the effect of cognitive rehabilitation in a sample of both HIV positive and HIV negative children. Five HIV positive and six HIV negative children were assigned to either an experimental or control group. The experimental group underwent two months of cognitive rehabilitation therapy remediating sustained attention, whereas the control group took part in placebo activities. Sustained attention measures were taken before and after the intervention training sessions, using a sustained attention subtest from the Test of Everyday Attention for Children (TEA-CH). A Mann Whitney U Test revealed that the experimental group (Mdn=38.50) did not differ significantly from the control group (Mdn = 37.00) after the cognitive rehabilitation intervention, U=12.00, z= -.55, p= .66, r= -.17. But a Wilcoxon Signed Rank Test found that there was a significant improvement from pretest scores (Mdn=31.00) to posttest scores (Mdn=38.00) following the rehabilitation for HIV positive participants in the sample, T=15.00, z = -2.02, p= .04, r= -.90. This raises the possibility that cognitive rehabilitation could be used as a low cost intervention in underdeveloped contexts

La thèse présentée a pour objectif d’analyser dans le cadre de l’approche dynamique du contrôle moteur la coordination motrice de participants sains et cérébrolésés évoluant sur un nouvel outil de rééducation, le cheval mécanique. L’analyse de ces coordinations spontanément adoptées par les individus sur ce cheval, ou modifiées suite à l’apprentissage d’une nouvelle coordination grâce à l’ajout d’un biofeedback visuel en temps réel, conduit à participer à (i) déterminer l’utilité du biofeedback dans ce type de tâche et (ii) à évaluer l’intérêt d’un protocole de 24 séances prescrites par nos soins et réalisées sur cet outil. L’objectif final est alors de participer à l’élaboration d’un protocole de rééducation posturale pour une population de patients cérébrolésés. La première étude a permis de mettre en avant le rôle joué par l’expertise dans l’évolution des coordinations posturales des individus sur le cheval mécanique amenant les cavalières expertes vers une coordination posturale plus adaptée (i.e. maintien des patterns en phase et en antiphase), en comparaison aux novices. Par ces analyses, la coordination tronc/cheval mesurée en antiphase, a été mise en lumière, correspondant ainsi à la coordination retrouvée dans l’activité équestre réelle. Par ailleurs, la mise en place d’une méthode d’apprentissage (étude 2) a permis de modifier le comportement postural des individus après seulement 3 séances, selon les conditions d’apprentissage prescrites. La fréquence d’oscillation du cheval avait un impact important sur la coordination des participants, qui adoptaient une coordination en antiphase (fort attracteur) lorsque la contrainte environnementale était élevée. Toutefois, ces observations n’ont pas permis de démontrer le réel intérêt de l’ajout d’un biofeedback visuel dans l’apprentissage d’une nouvelle coordination posturale chez des sujets sains. Enfin, la troisième étude réalisée chez des patients cérébrolésés a montré l’intérêt de cette nouvelle méthode de rééducation sur la coordination posturale de ces patients. Après 24 séances, leur coordination était différente de celle du groupe témoin, permettant de mettre en avant leur capacité à s’adapter aux contraintes et à développer des modes de coordinations posturales spécifiques (tronc/cheval en antiphase) à l’activité afin d’optimiser au mieux leur postureRooted in the dynamical system approach of motor control, the aim of this thesis is to analyze the motor coordination of healthy and brain-damaged participants oscillating on a new rehabilitation tool: the mechanical horse. The analysis of spontaneous coordination exhibited by individuals on this horse and the learned coordination adopted after a learning phase provided by the addition of a visual biofeedback allowed (i) to determine the usefulness of biofeedback in learning an oscillating task and (ii) to evaluate the interest of a 24 sessions rehabilitation protocol performed using the mechanical horse. The final goal is to participate to the development of a postural rehabilitation protocol for a population of brain-damaged patients. The first study allowed to highlight the role of expertise in the dynamics of the postural coordination on the mechanical horse bringing the expert riders towards a more adapted postural coordination (i.e. maintaining in phase and antiphase patterns). Through this first analysis, the spontaneous trunk/horse coordination was highlighted as antiphase, corresponding to the coordination found in real equestrian activity. Furthermore, the implementation of a learning method (study 2) allowed to modify the postural behavior of novice riders after only 3 sessions. The oscillation frequency had a significant impact on the coordination of participants who fell in an antiphase coordination (strong attractor) when the environmental constraint was high. However concerning those novice but healthy participants, this experiment did not demonstrate the real value of an additional video feedback during learning of a new postural coordination. Finally, the third study performed in brain-damaged patients showed the interest of this new rehabilitation method on the postural coordination of these patients. After 24 sessions, their coordination was different from the one of the control group, allowing to highlight their ability to adapt of constraints and to develop specific modes of postural coordination (trunk/horse antiphase) in order to optimize their posture

This quasi-experimental study investigates neuropsychological functioning differences between 63 active duty soldiers who were placed into three groups (MTBI, PTSD, control) to provide better information for differentiating PTSD and MTBI. The ANAM and MicroCog were utilized to measure psychomotor speed, memory, and attention. Participants with PTSD performed worse on most measures of psychomotor speed and attention, and endorsed more symptoms of depression and anxiety when compared to MTBI and control participants. Further, attention appears to be the best cognitive domain for differentiating PTSD from MTBI, whereas memory variables did not differentiate these groups.

Full textAbstract:
Based on ten experiments, this thesis examines representational neglect in brain damaged patients and in matched controls. The patients sometimes show a specific deficit in visual imaging: neglected one half of their mental representations. Although several studies addressed the issue of visuo-perceptual neglect, the representational defect is underinvestigated. Only a few standardized tests are available for its detention and assessment, and therefore rarely it is diagnosed in clinical practise or investigated in experimental work. In this thesis some new tests to investigate representational neglect are proposed. Moreover, representational neglect is evaluated in different sensory modalities (visual, tactile as well as within the personal domain) to address the issue of supramodality or plurimodality of this deficit.

Resumo: A esclerose múltipla (EM) é uma doença inflamatória e desmielinizante do sistema nervoso central que afeta cerca de 2,5 milhões de pessoas em todo o mundo e implica em um importante impacto social e econômico para o estado, resultante de incapacidades funcionais sensitivo-motoras e cognitivas. Nas últimas décadas, o estudo e o entendimento da EM se beneficiaram dos avanços das técnicas de neuroimagem. A Ressonância Magnética (RM) tem sido usada para estudar tanto a história natural da doença quanto para monitorar a eficácia de tratamentos, mas a correlação dos achados da RM convencional com os dados clínicos ainda é insatisfatória. Com isso, tem surgido o interesse em outras técnicas de RM, entre elas a avaliação da substância cinzenta cerebral. Entretanto, apesar dos avanços em neuroimunologia e neuroimagem, ainda existem poucos dados que possam predizer a incapacidade em longo prazo. Com isso, nosso objetivo foi identificar fatores clínicos e de RM relacionados a uma pior evolução clínica em pacientes com EM. Inicialmente nós realizamos um levantamento dos dados de 197 pacientes acompanhados no ambulatório de EM do HC-UNICAMP, levando em conta informações clínicas e epidemiológicas e o tempo que cada paciente levou para atingir escores específicos de incapacidade. Nós observamos que o grupo levou 25,8 anos para atingir o EDSS de 6,0, mas que pacientes do sexo masculino, e principalmente aqueles com surtos frequentes nos primeiros anos e com envolvimento do tronco cerebral ou cerebelo apresentaram uma evolução pior. Posteriormente, estabelecemos um subgrupo menor de pacientes a fim de estudar o comportamento longitudinal da patologia cerebral e sua relação com a incapacidade clínica e cognitiva. Foram acompanhados, durante um período de 24 meses, 43 pacientes com EM forma remitente-recorrente e 29 indivíduos controles, submetidos a exame neurológico, neuropsicológico e RM cerebral. O desempenho nos testes clínicos e neuropsicológicos foi pior no grupo dos pacientes, e 44,2% deles foram classificados como tendo disfunção cognitiva. Um pior desempenho cognitivo estava associado à presença de atividade subclínica da doença na RM, com uma alta carga lesional cortical e com a atrofia do corpo caloso. Além disso, uma maior incapacidade clínica também estava relacionada com estas lesões corticais, tanto cerebrais quanto aquelas presentes no córtex cerebelar. Como a presença de atividade subclínica foi um indicador importante de disfunção cognitiva, foi avaliado em um subgrupo de 15 pacientes a produção de citocinas pró-inflamatórias comparando com os dados de RM. Aqueles pacientes com lesões ativas na RM apresentaram uma produção significativamente maior de citocinas pró-inflamatórias, 10 vezes maior de INF-? e 22 vezes maior de TNF-?. O grupo de 43 pacientes foi acompanhado longitudinalmente e no final de 24 meses a atrofia cortical foi de 2,57% e da substância cinzenta subcortical de 3,8%, ambos significativamente maiores que no grupo controle. A presença de atrofia do tálamo no início estava relacionada a um maior risco de disfunção cognitiva após dois anos. Além disso, a presença de uma alta carga de lesões corticais no início do estudo estava relacionada a um risco 5,14 vezes maior de incapacidade clínica após 24 meses. Pode-se concluir que a substância cinzenta, cortical e subcortical, está difusamente afetada nos pacientes com EM, e que este dano progride consideravelmente em um período de dois anos, com importante impacto clínico e cognitivo
Abstract: Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system that affects about 2.5 million people worldwide. MS entails a significant economic impact due to both motor and cognitive functional impairments. In recent decades, the study and understanding of MS have benefited from advances in neuroimaging techniques. Magnetic resonance imaging (MRI) has been used to study both the natural history and to monitor the effectiveness of treatments, but the correlation of conventional MRI findings with clinical data is not yet fully satisfactory. Thus, there has been great interest in other MRI techniques, including the assessment of grey matter. Nevertheless, despite advances in neuroimmunology and neuroimaging, there are few data that can predict the long-term disability in MS patients. Therefore, our goal was to identify clinical and MRI factors related to a worse clinical outcome in patients with MS. Initially, we surveyed the data of 197 patients followed in the outpatient clinic of the MS center at UNICAMP University Hospital, gathering clinical and epidemiologic information and the time to achieve specific scores on EDSS disability scale. The median time from onset to the assignment of a disability score of 6 was 25.8 years, but male patients, especially those with frequent relapses in the first years of disease, and with involvement of the brainstem or cerebellum showed a worse outcome. Subsequently, we established a smaller subgroup of patients in order to study the longitudinal behavior of brain pathology as seen by MRI and its relationship to clinical and cognitive disability. We followed for a period of 24 months, 43 patients with relapsing-remitting MS and 29 healthy subjects, who underwent neurological examination, neuropsychological testing and brain MRI. At baseline, performance on clinical and neuropsychological tests was worse in the patients group, and 44.2% were classified as having cognitive dysfunction. Worse performance on neuropsychological battery was associated with the presence of subclinical MRI activity, with a high burden of cortical lesions and atrophy of the corpus callosum. In addition, worse clinical disability was also associated with these cortical lesions, both those in the brain as those present in the cerebellar cortex. As the presence of MRI subclinical disease activity was an important indicator of cognitive impairment, coupled with the fact that there are no strong biological markers so far, we assessed the production of proinflammatory cytokines in a subgroup of 15 patients and compared with MRI data. We found that patients with subclinical active MRI lesions had significantly higher production of proinflammatory cytokines, 10-fold greater in IFN-? and 22-fold in TNF-?. The group of 43 patients was followed longitudinally and after 24 months grey-matter atrophy was 2.57% in the cortex and 3.8% in subcortical structures, both rates significantly higher than in the control group. The presence of thalamus atrophy at the baseline was associated with an increased risk of cognitive dysfunction after 2 years. Furthermore, the presence of a high load of cortical lesions at baseline was related to a 5.14 fold increased risk of clinical disability after 24 months. It can be concluded that both cortical and subcortical grey matter are diffusely affected in MS patients, and that this damage progresses considerably over a period of two years, with important clinical and cognitive impact
