Daumas, Lyne. "Apathie chez la personne âgée présentant un trouble neurocognitif : associations avec la fatigue, répercussions physiques et impact sur la prise de décision dans le dilemme d'exploration-exploitation." Electronic Thesis or Diss., Université Côte d'Azur, 2024. http://www.theses.fr/2024COAZ4001.
Full textApathy is one of the most common neuropsychiatric symptoms in neurocognitive disorders. Defined as a disorder of goal-directed behavior, it manifests as a quantitative reduction in activities and relies, at least partially, on dysfunctions in reward processing and in decision-making that determine whether planned and directed actions are worth carrying out. Similarly, fatigue manifests as difficulties in initiating and maintaining activities and could share common central mechanisms with apathy. However, while we know that behaviors are affected by apathy, its repercussions in the physical dimension as well as its relationship with fatigue remain to be clarified. In particular, an investigation of how they do and do not overlap, and their impact physical capacities deserves further investigation. On the other hand, while several pieces of evidence support the idea that apathy is associated with disruptions in effort-reward-based decision-making, so far, very few studies have focused on decision making in an uncertain context, when reward values change over time and individuals have to choose between a more predictable option (exploitation) and a less certain but potentially more rewarding option (exploration). Yet, some evidence suggests that this “exploration-exploitation” decision-making could also be disrupted. Thus, the objective of this doctoral project was to identify, from decision-making to behavior, to what extent apathy is associated with fatigue, impacts physical capacities, and affects the ability to make optimal choices in a changing environment.Using self-reported questionnaires and through exploratory factor analysis, study 1, conducted in the general population, showed that the latent factors underlying the emotional and social dimensions of apathy did not include any element of fatigue, thereby suggesting that lack of emotional sensitivity and social motivation were specific to apathy. Conversely, the results highlighted overlaps between apathy and fatigue in the behavioral dimension regarding the reduction of activities, as well as in the mental/cognitive dimension. Then, this close relationship between apathy and fatigue was confirmed in patients with mild neurocognitive disorder in studies 2 and 3, where functional physical capacities were assessed. More specifically, apathetic patients reported greater levels of fatigue and exhibited increased fatigability on a sustained maximal grip strength task, in comparison to non-apathetic patients. Additionally, greater levels of apathy and fatigue were associated with a decrease in daily physical activities as well as reduced physical capacities. Taken together, these results underline the importance of assessing and treating apathy and fatigue in the context of neurocognitive disorders, and of considering their impact on physical functioning. As for study 4, using an experimental task, the results highlighted suboptimal decision-making in apathetic patients, characterized by longer response latency and excessive exploration. The latter was associated with lower performance on the neuropsychological test of mental flexibility. The possibility that apathetic patients may exhibit difficulties to flexibly adapt their responses, as well as the relevance of this paradigm as a theoretical and experimental framework, are then discussed. In conclusion, the results and research perspectives from this work contribute to a better understanding of the dysfunctions associated with apathy, helping the improvement of assessment and treatment

Full textIntroduction: Thanks to the progress of treatments and early diagnosis, cancers are better cured. However, during the disease and its treatments, patients often experience fatigue which could have an impact on disease progression and survival. Medical and psycho-social factors are associated with fatigue, which makes them important to evaluate in order to consider them properly when taking care of patients. Cancer prevalence is higher in the elderly, who are more affected by fatigue. This fatigue increases with frailty, characterized by a state of weakness, slow walking speed or unintentional weight loss. This is why we chose to focus on this specific populationThe objective of this thesis is to study the role of several psychosocial factors (coping, social support, depression and routinization) associated with fatigue in frail elderly patients with non-Hodgkin lymphoma.Method: This research, entitled Psyfrail, is an ancillary study to a randomized trial named Frail. The 50 patients included, with a mean age of 82 years old, were evaluated in terms of fatigue, depression, coping, social support and routinization during a meeting with a psychologist before the start of treatment (T1), in the middle (T2) and at the end (T3). Cross-sectional and longitudinal analyzes were conducted to highlight the factors associated with fatigue at different measurement times and with its evolution.Results: The use of problem-focused coping at T1 is associated with a decrease in general fatigue and reduced activity scores at T1 and a decrease in the reduced motivation score at T2. Routinization increases mental fatigue and reduced motivation scores at T2. Social support availability is associated with a smaller increase in the reduced motivation score over time. The decrease in general fatigue is reduced in patients with high level of emotion focused coping. Depression is associated with a higher fatigue at T1 and T2.Conclusion: The promotion of appropriate strategies to help patients cope with the disease and the treatment of depression could have a positive impact on reducing fatigue

Full textEffective interventions such as physical activity leading to disability prevention in the elderly are a public health priority. Disability outcome measures should ideally include objective measures such as physical performance tests. This work demonstrates the test-retest reliability of a new walking test (the 400-m usual pace walk test), the association between calf circumference and muscle-related disability and the predictive value of the short physical performance battery on mortality. Physical activity appears to be an effective strategy to delay disability. This work adds further evidence, especially in the frail elderly population (patients with Alzheimer's disease, obesity or malnutrition) of its health benefits

Full textThis study investigates the routinization in the elderly, defined as the performance of specific activities in the same manner over time, concerning environmental, behavioral, and social contexts. Integrating both adaptation and vulnerability dimensions, the literature involved in the development of this concept is analyzed and discussed as a general model of disability. Based on a sample of 235 participants from the PAQUID study, we then analyze the associations between preferences for routines and diverse vulnerability factors. The concepts of routinization and functional incapacities are compared, followed by an examination of the impact of preferences for routines on specific vulnerability factors, and an analyze of distinct profiles of routinization. The results of this study are discussed relative to different dimensions of the routinization, methodological limits and its implications for both clinical and public health efforts

Full textIn France, aging is a major public health challenge. Specific aging-associated physiologic modifications can produce movement disorders and lead to dependency and institutionalization in nursing homes. Clinical examination of postural deficits is generally achieved by means of stabilometric evaluation. Recordings of center of pressure (COP) displacements can be analyzed in two ways : (i) a classical approach based on kinematics and descriptive statistics or (ii) a dynamical approach which provides a quantification of the complexity of COP time series in terms of regularity. In this work, we statistically show the complementarity of these two approaches. We also highlight the clinical interest of the dynamical approach with two clinical studies : (i) an exploration of the relationship between a functional test and postural evaluation in asymptomatic sedentary older women ; (ii) a comparison of institutionalized elderly non-fallers and fallers based on a dynamical analysis of COP fluctuations

Full textPsychomotor retardation (PMR) is a fundamental feature of depressive illness but also atypical clinical presentations of depression in the elderly. It is poorly recognized because of the common confusion with age-related slowing. We hypothesized that PMR associated to depression differed from normal aging. We performed two reaction time experiments using an additive factor analysis in healthy and depressed old individuals. Age-related slowing affects all the central nervous system information processing stages while only response-selection and motor-adjustment stages are functional targets prolonged by depression. As in younger adults, depression spares stimulus preprocessing in old individuals. Then, we validated the Retardation Rating Scale (RRS) in 165 old inpatients (107 were depressed). The RRS, an objective tool that measures psychic and motor aspects of PMR, shows good psychometric properties and allows a better detection of depression than standard depression scales in this geriatric sample. We also validated a short version of the RRS, considering the four most relevant items. The identification and the measure of the PMR in geriatric depression will improve our knowledge about neurobiological pathways underlying depressive illness, the treatment efficacy evaluation and the detection of depression in the elderly
Zakaria, Firas. "Human locomotion analysis : exploitation of cyclostationarity properties of signals." Thesis, Saint-Etienne, 2015. http://www.theses.fr/2015STET4019/document.
Full textThe research work presented in this dissertation, involves the development of novel methodologies and methods, for the exploitation of cyclostationarity properties and for the treatment of ground reaction force signals, recorded during walking and running. We are especially interested in the analysis of human locomotion in three fields of interest: a study relating to pathology, a study directly related to age, and a study of muscle fatigue. Indeed, the detection of risk of falling among the elderly for the prevention of falls is of major concern. This is because falling on the one hand leads to a large number of deaths and secondly, resulting in higher costs of public health.Study the muscle fatigue in particular has occupied taken a big share out of this research due to the importance of such events like strenuous level of sports. Research and development of new methods and indicators in the field of signal processing for better characterizing the human locomotion, would allow interesting advances in the aforementioned issues. The complexity of GRF signals is defined by the neuromuscular system which generates this signal. Improved knowledge of this system requires developing source separation methods and advanced signal processing tools to better describe the system under consideration. Indeed, we will endeavor to show in this dissertation that GRF signals can be modeled within an enlarged cyclostationary framework. The GRF signal components (active and passive contribution) are separated by means of new source separation techniques. This modeling opens new perspectives for the decomposition and identification of individual sources. On the other hand, we exploit the cyclostationary characters of signals in the context of Morphological component analysis (MCA) method. Such algorithm enables us to successfully separate the first and second order components of the signals under consideration. Finally, we provide a new model useful for studying and characterizing cyclostationarity. It presents the impact of random slope variation on the cyclic spectrum of the signal. We call this model the random slope modulation (RSM). We apply this model for studying biomechanical signals where we consider the slope as a specic measure extracted from the vertical ground reaction forces. The results show that the slope and polynomial random coefficients of passive peaks can play important role and provide interesting information concerning fatigue and concerning running / walking performance

Full textThe study in the elderly of their specific troubles in feeding behaviour has reinforced the idea that such a state is far from unusual and is rather specific to people of an advanced age. The refusal of food in elders is often analysed as the expression and/or the consequence of somatic or psychiatric disease. However, its observation outside of any medical context, has led us to try to understand the emergence and the meaning of this behaviour, which worsens after institutionalisation of elderly people. In researching causality, we have found that placement in an institution, which often occurs in an emergency situation and sometimes without the approval of the concerned person, seems to play a major role in the transition from disorder to denial. This correlation between behaviour and institutionalisation raises several questions. Why does this event of institutionalisation bring in some elders, an inability to face this new challenge, as if all internal resources necessary for reconstruction were annihilated, preventing any psychic adaptation and leading to death ? Is it no because the body of elderly persons becomes the necessary element, the mediator, in the violent act of refusal of food, for understanding their pain, their wish for "non-life" ? The lack of words, the violence of the refusal of food, challenge the subject's entourage. How do the health care team and the family situate themselves in this anguished relation ship ?

Full textThe great variety of emotional experience can be explained as a function of emotion-cognition interactions. Given that some cognitive aspects decline with age, in parallel to finer degrees of emotional control, the relationship between age and emotionally induced feeling states was examined. Older subjects, compared with younger participants, showed less positive affects and more negative emotions. Since neuropathological conditions, such as in degenerative diseases, present a considerable impact on brain processes, an evaluation of cognitive function and emotional reactivity was undertaken in patients with ALS, compared to matched controls. The evolution of these parameters over a one year period was assessed. ALS patients were significantly more depressed than controls, and depression increased over the study period. While there was no observable change in memory and retrieval non-frontal cognitive functions, a performance deficit linked to frontal executive processing was detected suggesting a very mild defect in cognitive function. These deficits, unlike neuromuscular function and depression, did not aggravate over the period of the study. Emotional reactivity, in spite of some variability that can be best explained in terms of the heterogeneity of patients' profiles, did not differ significantly between ALS patients and controls. The study provides evidence for a mild defect in frontal cognitive processing in ALS patients, that evolves only slowly, if at all, with time. On the contrary, the profile of emotional processing in ALS seems to be affected to some extent

Full textAdverse drug reactions in older people are frequently encountered and are at times serious; the quality of geriatric prescription is thus a main issue. Potentially inappropriate drugs are medications with an unfavourable benefit/risk ratio or a questionable efficacy while other and safer therapeutic alternatives are available. We propose a list of potentially inappropriate medications for patients aged 75 years or over, adapted to the French medical practice, and established with the use of a Delphi consensus method. The list includes 34 explicit criteria established for an epidemiological purpose. Medications from this list should generally be avoided when possible in the aged. As therapeutic alternatives are put forward, the list could be considered as a prescription aid. However it should not be regarded as a unique tool for reducing adverse drug effects. Actually we have shown that inappropriate medications are not the main source of adverse effects. The number of drugs prescribed is a risk factor of both potentially inappropriate medication use and of adverse effect occurrence in the elderly. We have shown that admission to a hospital geriatric unit allows a reduction of the overall number of medications and especially that of inappropriate drugs. Our study also addresses the differing points of view between geriatricians and general practitioners. Prescription in the aged should be regarded with a particular attention and should be helped by periodical continuous medical education. Moreover, the general population awareness about this topic is to be enhanced. When regarding both epidemiological studies and elderly patient treatments, objective and subjective approaches are necessary in order to understand better drug induced iatrogenic effects and reduce their prevalence

Full textBrutal onset retropulsion is a postural disturbance specific to old age, which is studied here in its psychic aspects. Retropulsion provokes questions on their mortality in affected persons, during a period which they interpret as a psycho-social collapse. A rehabilitation programme is the most appropriate and effective treatment because the specialised approach of the Physiotherapist encourages work on a practical physical level, removing the tangle of morbid implications associated with the symptom. The physical improvement progresses alongside a repression of the imagined fears, a repression necessary in order to allow the sufferer to distance themselves from the subconscious motivations activated at the moment of the appearance of the retropulsion. Retropulsion as a defence mechanism can be recognised as an updating of the archaic reactions previously used during the development of the Inner Personality, this entity psychic feeling threatened at the moment of the postural disturbance

Full textWe treat essentially the field of the apparition late in life of delusions. Old age, which is an important crossroads in life, is also the period of an economic redistribution of investments. Even if they appear tardily, delusions, whether insane or not, are not systematically synonymous with a psychotic state. They show confusion and unreal speech, that we hesitate to call "delusions". The delusional conviction dulls with age, and we observe a levelling of beliefs and unreal productions. This last point might enable us to put into question, either the definition of delusion itself, or what we use to call delusional ideas of elderly people. Only clinical medecine could give us some clarifications on these delusional uncertainties we observe daily. We show with evidence that we do have to clearly define the frontier between the normal and the pathological

Full textDocosahexaenoic acid (DHA) is a polyunsaturated fatty acid from the omega 3 family. DHA reduces risk factors of cardiovascular diseases, and has positive effects on neurological diseases. In most studies, the origin of DHA is triacylglycerols from fish oil. The originality of our two clinical studies is to bring DHA in the form of egg phospholipids, and to a dose close to the French Recommended Dietary Allowances. In the first study, during 9 months, 24 elderly have consumed desserts made with egg yolk powder enriched in DHA (150mg/d of DHA). The levels of DHA and unexpectively that of arachidonic acid increased in plasma and erythrocyte membranes. Hematocrit and mean corpuscular volume (MCV) decreased. Visual acuity was measured at 0, 10 and 15 months on ten elderly. Visual acuity of men increased between 0, 10 and 15 months, while that of women decreased between 0 and 10 months, then plateaued. The second study, involved two groups of sportsmen. The "DHA" group consumed, during 8 weeks, pasta made with DHA enriched egg (110mg/d of DHA). While the control group consumed, during 4 weeks, pasta made with regular egg, and during 4 weeks pasta made with DHA enriched egg. In erythrocyte membranes of "DHA" group, an increase of the levels of DHA and unsaturated fatty acids was observed. On ergocycle, during the supplementation, the "DHA" group improved their VO2max, recuperation factor and oxygen pulse, their hematocrit and MCV significantly decreased. These parameters did not significantly changed in the control group. These data suggest that low doses of DHA-phospholipids can affect the regulation of lipidic metabolism, and induce physiological effects

Full textThis work presents severals new contributions in modelisation and in the field of physical activity in the elderly. Force and equilibrium are both involved in posture and lifting. It is possible to employ index of strategies which allow to quantify those activities, in order to evaluate the possible relation between lifting and posture. To make postural evaluation easier and to evaluate load lifting, we describe two new models based on inverse geometric augmented body. The first model is able to measure ankle and hip movement and the secund model is able to identify the strategy employed during lifting. Each model only requires force plate measurements. The last part of this thesis focus on the study of the level of physical activity in elderly and its consequences on equilibrium and force. We find a relation between postural strategy and lifting strategy in elderly with a physical activity between 2-4 hours per week. Performances of the equilibrium system and those of the motor system are perhaps involved in a different level in the choice of postural strategy and lifting strategy. Our results underline the fact that even a low level of physical activity positively influences daily activities of elderly

Full textA poor postural stability in older people is associated with an increased risk of falling. Posturographic and clinical tool have widely been used to assess balance control; however their value in predicting falls remains unclear. The purpose of this prospective study was to determine the predictive value of posturography in the estimation of the risk of falls, including a comparison with standard clinical balance tests, in healthy non-institutionalized persons aged over 65. Postural control was evaluated by posturographic static and dynamic tests and Sensory Organization Test (SOT) and by clinical balance tests (Timed «Up & Go» test, One-Leg Balance, Sit-to-Stand-test) in 206 elderly subjects. Subsequent falls were monitored prospectively with self-questionnaire sent every four months for a period of 24 months after the balance testing. Loss of balance during the last trial of the SOT sensory conflicting condition was the best factor to predict risk of recurrent falls and intrinsic falls. Multiple drugs use and history of falls were associated with risk of falls. Clinical balance tests, static tests and dynamic tests revealed no significant differences between the groups. In a sample of non-institutionalized older persons aged over 65, posturographic evaluation by the SOT, especially in sensory conflicting condition, appears to be a more sensitive tool to identify those at high risk of recurrent falls or risk of intrinsic falls

Full textThe ageing of the French population raises the problem of the management of the consequences of chronic diseases, expressed in terms of disability. The objective of this dissertation was to describe the different domains of disability affected in elderly people, the evolution of the disablement process in terms of progression, regression or death, and its determinants. The analyses were conducted on the PAQUID cohort, where 3777 subjects aged 65 years and over were followed-up and the Three-City study. Multi-state Markov models were used to estimate disability-free life expectancies and to study the role of diseases (dementia, diabetes, dyspnoea, obesity), but also that of individual and environmental factors (sex, education, depression, medi-social care) on the disablement process. Finally, an important decline of the prevalence of disability was observed over ten years between two generations of elderly people

Full textThe number of elderly people in the world is constantly increasing, hence the challenge of helping them to continue to live at home and ageing in good health. This PhD takes part in this public health issue and proposes the detection of the person behavior change based on the recording of activities in the home by low-cost depth sensors that guarantee anonymity and that operate autonomously day and night. After an initial study combining image classification by machine learning approaches, a method based on Resnet-18 deep neural networks was proposed for fall and posture position detection. This approach gave good results with a global accuracy of 93.44% and a global sensitivity of 93.24%. The detection of postures makes possible to follow the state of the person and in particular the behavior changes which are assumed to be the routine loss. Two strategies were deployed to monitor the routine. The first one examines the succession of activities in the day by computing an edit distance or a dynamic deformation of the day, the other one consists in classifying the day into routine and non-routine by combining supervised (k-means and k-modes), unsupervised (Random Forest) or a priori knowledge about the person's routine. These strategies were evaluated both on real data recorded in EHPAD in two frail people and on simulated data created to fill the lack of real data. They have shown the possibility to detect different behavioral change scenarios (abrupt, progressive, recurrent) and prove that depth sensors can be used in EHPAD or in the home of an elderly person

Full textDepression is an underdiagnosed complication of dementia, both disorders sharing some manifestations. The aim of this cross-sectional observational study was to examine the prevalence of depression among nursing home residents suffering from dementia, and to evaluate the sensitivity of detection of this disorder by the primary care team. Clinical profiles were assessed using the Cornell Scale for Depression in Dementia, the Structured Clinical Interview for DSM-IV, the Neuropsychiatric Inventory, the Quality of life in Alzheimer’s Disease Scale and the Mini Mental State Examination. Among 116 residents from 10 nursing homes, 17 cases of depression were diagnosed, from which only 7 had been detected by the clinical staff. Depression cases had a significantly poorer quality of life and a worse score on the NPI-NH distress scale. Overall, this study reveals that depressive syndromes are under-diagnosed in nursing homes residents and have a negative impact on quality of life of patients.
