Abstract:

Anosognosia and hemineglect are among the most startling neurological phenomena identified during the 20th century. Though both are associated with right hemisphere cerebral dysfunction, notably stroke, each disorder had its own distinct literature. Anosognosia, as coined by Babinski in 1914, describes patients who seem to have no idea of their paralysis, despite general cognitive preservation. Certain patients seem more than unaware, with apparent resistance to awareness. More extreme, and qualitatively distinct, is denial of hemiplegia. Various interpretations of pathogenesis are still deliberated. As accounts of its captivating manifestations grew, anosognosia was established as a prominent symbol of neurological and psychic disturbance accompanying (right-hemisphere) stroke. Although reports of specific neglect-related symptomatology appeared earlier, not until nearly 2 decades after anosognosia’s inaugural definition was neglect formally defined by Brain, paving a path spanning some years, to depict a class of disorder with heterogeneous variants. Disordered awareness of body and extrapersonal space with right parietal lesions, and other symptom variations, were gathered under the canopy of neglect. Viewed as a disorder of corporeal awareness, explanatory interpretations involve mechanisms of extinction and perceptual processing, disturbance of spatial attention, and others. Odd alterations involving apparent concern, attitudes, or belief characterize many right hemisphere conditions. Anosognosia and neglect are re-examined, from the perspective of unawareness, the nature of belief, and its baffling distortions. Conceptual parallels between these 2 distinct disorders emerge, as the major role of the right hemisphere in mental representation of self is highlighted by its most fascinating syndromes of altered awareness.

Abstract:

Background: Rehabilitation for unilateral spatial neglect (USN) using prism adaptation (PA) is one of the most widely used methods, and the effectiveness of PA is well-evidenced. Although the effect of PA generalized various neglect symptoms, the effectiveness for some aspects of neglect is not fully proven. The Catherine Bergego Scale (CBS) was developed to identify problems with the activities of daily living (ADL) caused by USN. The CBS is composed of 10 observation assessments and a self-assessment questionnaire. To assess the self-awareness of USN, the anosognosia score is calculated as the difference between the observational scores and the self-assessment scores. To investigate how PA affects ADL and self-awareness in subacute USN patients during rehabilitation, we analyzed each item of the CBS and self-awareness from a randomized, controlled trial (RCT) that we previously conducted (Mizuno et al., 2011). Methods: A double-masked randomized, controlled trial was conducted to evaluate the effects of a 2-week PA therapy on USN in 8 hospitals in Japan. We compared each item of the CBS, anosognosia score, and absolute value of the anosognosia score between the prism group and the control group. Results: Two of ten items (gaze orientation and exploration of personal belongings) were significantly improved in the prism group compared with those in the control group. The absolute value of the anosognosia score was significantly improved by PA. Conclusions: Improvement of oculomotor exploration by PA may generalize the behavioral level in a daily living environment. This study suggested that PA could accelerate the self-awareness of neglect during subacute rehabilitation.

Abstract:

Objective: The purpose of this study was to investigate anosognosia for hemiple gia (AHP) in the rehabilitation phase after onset of stroke. Methods: Forty-six hemi plegic stroke patients, 29 with right hemisphere damage (RHD) and 17 with left hemi sphere damage (LHD) were evaluated ∼1 month after onset of stroke. Anosognosia was evaluated with an implicit measure designed to assess anosognosic behaviors (choosing between unimanual and bimanual tasks), in addition to a traditional ex plicit verbal measure. Results: AHP was found m 28% of the RHD and 24% of the LHD group. The majority of patients with AHP in the RHD group had large lesions involving the frontal, parietal, or temporal lobes and had coexisting sensory deficits and unilateral spatial neglect, whereas the LHD patients with AHP had predominantly small subcortical lesions and no sensory or attentional deficits. The functional out comes of AHP patients in both hemisphere groups revealed their inability to retain safety measures at discharge from rehabilitation (p < 0.036) and their need for assis tance in basic and instrumental activities of daily living at follow-up. Conclusions: AHP presents a significant risk for negative functional outcome in stroke rehabilita tion. The underlying mechanisms of AHP may be different for left and right hemi sphere patients, therefore requiring different intervention approaches. Key Words: Anosognosia—Cerebrovascular accident—Rehabilitation outcome.

Abstract:

Anosognosia of hemiplegia is of interest for both pragmatic and theoretical reasons. We discuss several neuropsychological theories that have been proposed to explain this deficit. Although for psychological reasons people might deny deficits, the denial hypothesis cannot account for the hemispheric asymmetries associated with this disorder and cannot explain why some patients might deny one deficit and recognize another equally disabling deficit. There is some evidence that faulty feedback from sensory deficits, spatial neglect and asomatognosia might be responsible for anosognosia in some patients. However, these feedback hypotheses cannot account for anosognosia in all patients. Although the hemispheric disconnection hypothesis is appealing, disconnection is probably only a rare cause of this disorder. The feedforward intentional theory of anosognosia suggests that the discovery of weakness is dependent on attempted action and some patients might have anosognosia because they do not attempt to move. We present evidence that supports this theory. The presence of one mechanism of anosognosia, however, does not preclude the possibility that other mechanisms might also be working to produce this disorder. Although a large population study needs to be performed, we suspect that anosognosia might be caused by several of the mechanisms that we have discussed. On the basis of the studies of impaired corporeal self–awareness that we have reviewed, we can infer that normal self–awareness is dependent on several parallel processes. One must have sensory feedback and the ability to attend to both one's body and the space where parts of the body may be positioned or acting. One must develop a representation of the body, and this representation must be continuously modified by expectations (feedforward) and knowledge of results (feedback).

Abstract:

AbstractAn 8-year-old right-handed girl manifested aphasia after bilateral thalamic infarcts. The features of thalamic aphasia are similar to that of previously reported patients with thalamic lesions. Paucity of speech, reduced voice volume, some paraphasia, and severe dysgraphia were present, but comprehension and repetition were preserved. Thalamic aphasia is usually associated with left thalamic lesions. Our patient also had spatial neglect and anosognosia probably due to right thalamic infarction. She had recovered near-normal speech after rehabilitation.

Abstract:

AbstractIn this paper different models of anosognosia are confronted and data concerning denial behaviors are presented that were collected on a selected population of right brain-damaged patients affected by motor and neglect disorders. Anosognosia for motor impairment and anosognosia for cognitive impairments were found to be dissociated, as well as anosognosia for the upper and lower limb motor impairments. These findings are then discussed in an attempt to choose the more suitable theoretical framework for interpreting the various disorders related to denial of illness. (JINS, 1996, 2, 426–440.)

Abstract:

Objective of the Review: To present data from the latest research studies focusing on anosognosia for neurological deficit in patients with acute ischemic stroke. Key Points: Anosognosia for motor and cognitive deficit is a quite common disorder in acute ischemic stroke patients. This condition is of interest for neurologists because it manifests itself in an unusual way and has a negative impact on patients’ medical rehabilitation. The understanding of the pathophysiology of anosognosia and its neuroanatomical underpinnings is changing and improving. New information about approaches to the diagnosis and treatment of this condition is becoming available, making this review timely. Conclusion: Patients with acute ischemic stroke may have reduced perception of their neurological deficit and cognitive, emotional, and behavioral disorders. Hemispatial neglect is the most common cognitive disorder associated with anosognosia for paralysis. Medical rehabilitation of post-stroke patients with anosognosia is challenging and requires the participation of a multidisciplinary team and a differentiated approach, tailored to the type of anosognosia. At present, rehabilitation specialists have started discussing the possibility of therapeutic application of instrumental investigation techniques, such as caloric vestibular stimulation and transcranial brain stimulation, in addition to cognitive behavioral therapy. Keywords: reduced perception of disease, anosognosia, regulatory dysfunction, neglect, ischemic stroke.

Abstract:

More research is needed to better understand the impact of occupational therapy (OT) in stroke patients and syndromes of unilateral neglect (UN) and anosognosia. A prospective, observational, longitudinal design was conducted on a sample of 27 OT patients. The objectives were to examine: (1) the presence of UN and anosognosia; (2) the functional outcomes; and (3) the association of UN at baseline with functional status at discharge from OT. The outcomes were Barthel (functional independence) and the Rivermead Mobility Index (RMI). The baseline proportion of participants with UN was 33% according to the Star Cancellation Test (STC), and 48.1% according to the Catherine Bergego Scale (CBS) therapist-version. There was a significant difference between the therapist and participant-rated CBS scores (p = 0.004). Functional independence improved significantly between the initial and final assessments (p < 0.001); the effect size (r) was large (r = 0.61). There was a significant improvement in RMI scores (p < 0.001), which was large in size (r = 0.59). Both the STC and CBS-therapist scores were significantly correlated with the Barthel (p < 0.001, p = 0.005, respectively) and with the RMI (p = 0.004, p = 0.028, respectively). The participants substantially enhanced their functional status skills. UN and anosognosia were common problems, and neglect was associated with worse OT program outcomes.

Abstract:

Anosognosia for hemiplegia is a multifaceted syndrome that has a detrimental impact on the patient. Various theories based on behavioural and neuroanatomical data have been proposed to explain the mechanisms underlying the symptoms. These approaches have resulted in the development of a number of different proce- dures aimed at reducing symptoms or enhancing residual aware- ness. The article reviews rehabilitation attempts and their effects on individual cases and groups of patients. A selection of material was made using indexed articles published between 1987 and 2019. The inclusion criteria were: i) the presence of a neuropsychological assessment and ii) the presence of one or more methods specifically used to reduce AHP symptoms, or to enhance residual forms of awareness. The review indicates that intervention procedures have moved from bottom-up to more cognitive and metacognitive approaches. In fact, initially anosognosia for hemiplegia was considered to be a co-oc- current symptom of other neuropsychological conditions (e.g. spa- tial neglect) and interventions were borrowed from the rehabilitation techniques that had had success in relieving these other disorders. When anosognosia was identified as an independent syndrome and residual forms of awareness were demonstrated, procedures attempting to modulate awareness started to focus on specific components of the disease, such as visual perspective, motor monitoring and the updating of beliefs. Although further research is needed in this field, the most recent approaches seem to give more stable, lasting results than earlier methods. A timeline for interventions relating to anosognosia is suggested, and ethical issues are also discussed.

Abstract:

Die Neglektdyslexie ist alltagsrelevante Folge eines Neglekts, in der Forschung und bei der Entwicklung effektiver Behandlungsmethoden jedoch stark unterrepräsentiert. Typische Fehler sind Omissionen, Substitutionen und Additionen von Wörtern und Buchstaben in der kontraläsionalen Raumhälfte mit resultierender Beeinträchtigung des Lesesinnverständnisses. Häufigste Ursache sind Läsionen des rechten Parietallappens – oft mit Ausdehnung in den Okzipital- und Temporallappenbereich. Anhand des 3-Stufen-Modells der visuellen Wortrekognition von Caramazza & Hillis (1990) können Neglektdyslexien unterteilt werden in spatiale (stimuluszentrierte) und positionale (wortzentrierte) Formen. Bislang existieren keine störungsspezifischen Programme zur Therapie der Neglektdyslexie, so dass Übungen zur Behandlung von zentralen, hemianopen und Entwicklungsdyslexien adaptiert werden müssen. Dabei müssen neglektspezifische Phänomene (wie Anosognosie, fehlender Leidensdruck, Konfabulationsneigung oder ein geringer selbständiger Transfer) berücksichtigt werden.

Abstract:

This study describes the long-term effectiveness on spatial neglect recovery of a 2-week treatment based on prism adaptation (PA). Seven right-brain-damaged patients affected by chronic neglect were evaluated before, after two weeks of the PA treatment and at a follow-up (variable between 8 and 30 months after the end of PA). Neglect evaluation was performed by means of BIT (conventional and behavioral), Fluff Test, and Comb and Razor Test. The results highlight an improvement, after the PA training, in both tasks performed using the hand trained in PA treatment and in behavioral tasks not requiring a manual motor response. Such effects extend, even if not significantly, to all BIT subtests. These results support previous findings, showing that PA improves neglect also on imagery tasks with no manual component, and provide further evidence for long-lasting efficacy of PA training. Dissociations have been found with regard to PA efficacy on peripersonal, personal, and representational neglect, visuospatial agraphia and neglect dyslexia. In particular, we found no significant differences between the pre-training and post-training PA session in personal neglect measures, and a poor recovery of neglect dyslexia after PA treatment. The recruitment of a larger sample could help to confirm the effectiveness of the prismatic lenses with regard to the different clinical manifestations of spatial neglect.

Abstract:

Abstract BACKGROUND Cortical and subcortical electrostimulation mapping during awake brain surgery for tumor removal is usually used to minimize deficits. OBJECTIVE To use electrostimulation to study neuronal substrates involved in spatial awareness in humans. METHODS Spatial neglect was studied using a line bisection task in combination with electrostimulation mapping of the right hemisphere in 50 cases. Stimulation sites were identified with Talairach coordinates. The behavioral effects induced by stimulation, especially eye movements and deviations from the median, were quantified and compared with preoperative data and a control group. RESULTS Composite and highly individualized spatial neglect maps were generated. Both rightward and leftward deviations were induced, sometimes in the same patient but for different stimulation sites. Group analysis showed that specific and reproducible line deviations were induced by stimulation of discrete cortical areas located in the posterior part of the right superior and middle temporal gyri, inferior parietal lobe, and inferior postcentral and inferior frontal gyri (P > .05). Fiber tracking identified stimulated subcortical areas important to spare as sections of fronto-occipital and superior longitudinal II fascicles. According to preoperative and postoperative neglect battery tests, the specificity and sensitivity of intraoperative line bisection tests were 94% and 83%, respectively. CONCLUSION In humans, discrete cortical areas that are variable in location between individuals but mainly located within the right posterior Sylvian fissure sustain visuospatial attention specifically toward the contralateral or ipsilateral space direction. Line bisection mapping was found to be a reliable method for minimizing spatial neglect caused by brain tumor surgery.
