Ten Years after the National Alzheimer's Plan: Dementia Remains a Hidden Syndrome in France

Ten years after the implementation of the French Plan on Alzheimer's Disease (2008-2012), the present study aimed at describing the situation of the persons living with dementia in terms of diagnosis and high-risk situations (living alone, continuing driving, inability to handle budget and to manage medication). Among the 115 dementia cases followed-up in the AMI population-based cohort on aging in 2018 (i.e. ten years after the launch of the Plan), the prevalence of under-diagnosis was similar to the one estimated ten years earlier (53.0% vs. 55.6%). Almost all cases (95.3%) were concerned by high-risk situations (61.2% were unable to handle finances, 48.2% were living alone, 27.1% continued driving). Being diagnosed as demented was not associated with a lower frequency of high-risk situations, excepting for driving (16.7% vs. 37.2%). Ten years after the beginning of the French Alzheimer's Plan, dementia remains a hidden syndrome, with a frequent inadequate management of high-risk situations.
