The CIRCAME study is a bicentric study of patients from 2 memory clinics in Paris. The main objective is to identify circadian rhythm components and other individual risk factors (sociodemographic, behavioral, and health related factors) associated with the diagnosis of subtypes (AD, Lewy bodies, vascular, frontotemporal dementia) and stages (cognitively healthy, mild cognitive impairment, clinical dementia) of dementia, independent of known risk factors (sociodemographic and genetic) and assess the relevance of use of these factors in primary care for screen of dementia including subtypes and stages. A secondary objective is to determine factors associated with progression of the disease, in terms of cognitive decline and limitations in activities of daily living, as well as progression to dementia among cognitively healthy controls and patients with mild cognitive impairment, up to 15 years after the inclusion period.
