title: The PREMAP Study: prevalence and risk factors of dementia and clinically diagnosed Alzheimer's disease in Provence, France. Prevalence of Alzheimer's Disease in Provence.
abstract: The PREMAP Study investigated the prevalence and risk factors of dementia and Alzheimer's Disease (AD) in a random sample of 1062 residents 70 year old or more, living in south-eastern France (private homes and institutions). All persons living in institutions for the elderly (n = 258) and community dwellers (n = 804) scoring less than 24 points on the MMSE (18.4%) were invited to undergo a medical evaluation at home by a qualified neurologist using the CERAD battery. We found 177 cases of dementia (9.2%), including 82 cases of AD (5.5%). Prevalence of AD increased significantly with age and was higher among women (OR: 4.24) and persons with no formal educational level (OR: 2.47). While a MMS score less than 24 was more frequent among persons with a foreign native language (OR: 3.05), the OR and AD was not significantly associated with native language. The proportion of AD among persons suffering from senile dementia was 45% among elderly living in institutions and 69% among those living in the community. Prevalence rates in south-eastern France are similar to the average rates for Europe. This study underlines the need to investigate the relationships between native language, MMSE and AD on the one hand, and the link between a low MMSE score and institutionalisation of patients suffering from AD on the other.
