Prevalence of Impaired Executive Functions in Institutionalized Elderly

The evaluation of executive functions, as well as the means of stimulating and preserving them, are at the heart of the challenges for maintaining a level of functional autonomy in the elderly, but also during the loss of this functional autonomy and when entering a situation of dependence and/or dementia. Research that has demonstrated the preponderant role of executive functions on functional abilities are examples of this. Components such as planning, organization, initiation, mental flexibility appear to be strongly correlated with the effective performance of complex activities of daily living. In addition, the capacities for autonomy were found to be significantly reduced, and significantly with the severity of the executive deficits. In addition, if these data have since contributed to determining a level of impairment of the executive processes specific to an early loss of autonomy, they are so in the context of early diagnosis of dementia and validation of a detection tool, early loss of autonomy. The scientific advances of the last five years contribute to a better understanding of the impact of executive disorders, but on the other hand, the diversity of the explanatory phenomena of these disorders considerably complicates their nosology within neuro-evolutionary pathologies. Ultimately, an analysis of executive function disorders must take into account cognitive and behavioral aspects, that is to say, beyond performance on tests identified as involving executive functions, behavioral disorders, emotional status and level of autonomy in activities of daily living. In the state of our knowledge, the consideration of executive functions represents a strategic point at the crossroads of the evaluation of the act of care and treatment. Establishing data on the prevalence of alterations in the executive functions of residents, exploring the possibilities of evaluation with a battery of tests little used in this context and linking "executive" profiles and clinical situations seems to us a relevant and interesting first step. However essential to provide a beginning of answer to these questions. This study being an exploratory study. The results of this study will constitute new prevalence data in the population of residents of nursing homes. The aim here is to establish data on the prevalence of alterations in the executive functions of residents, to explore the possibilities of evaluation with a battery of tests little used in this context and to relate the profiles "executives" and clinical situations. This in order to develop a methodology to draw up a general assessment, and to make comparisons of the different profiles, inter/intra pathologies and stages of evolution. Thus, a more in-depth knowledge of the specific profiles of Nursing Home residents will also lead to the reflection of pharmacological and non-pharmacological therapeutic strategies. Finally, it will ultimately be a question of presenting an inventory of the situation of Nursing Home to alert public policies. The main objective is to study the prevalence of impaired executive functions in nursing home residents. The secondary objectives are to explore the feasibility of carrying out executive function tests and to examine the coorelationbetween the levels of impairment of executive functions and the clinical and functional characteristics of residents.
