Evaluation and Characterization of Behavioural Disorders and Dementias by the Behavioural Dysexecutive Syndrome Inventory (BDSI)

Study Overview
=================
Brief Summary
-----------------
Behavioural disorders are very common right from the initial stage of dementia and contribute to loss of autonomy. Behavioural dysexecutive disorders have a particular status due to their prevalence and their diagnostic importance, as they often constitute the initial symptoms of Frontotemporal Dementia (FTD), Semantic Dementia (SD) and Huntington's disease (HD) and they are classically more frequent in vascular dementia (VaD) than in Alzheimer's disease (AD). The presence of these disorders at the stage of Mild Cognitive Impairment (MCI) has only been partially evaluated and would increase the risk of progression to dementia. These classical data are based on non-standardized assessments and non-validated diagnostic criteria. The Groupe de Reflexion pour l'Evaluation des Fonctions EXécutives (GREFEX) has developed a standardized assessment tool for behavioural dysexecutive disorders, the Behavioural Dysexecutive Syndrome Inventory (BDSI) and has validated diagnostic criteria for this syndrome.
