[Caregiver burden in dementia: relationships with the activities of daily living, behavioral, and psychological symptoms].

The prevalence of Alzheimer disease and other dementia is increasing. Caregivers' burden is a major determinant of patient's institutionalization. Therefore, it seems relevant to take it into account to postpone nursing home placement. Zarit Burden Inventory (ZBI) is the most widely used tool to assess the caregiver burden. Recent studies have shown that it is not correlated to the patients' daily functional abilities, but to the patient's level of behavioral disturbances. It also depends on how they are experienced by the caregiver and, in particular, on the caregiver's personality. This encourages the development of caregiver group interventions aimed to improve their coping strategies.
