title: [Stroke in elderly: what have we learned from stroke epidemiology in younger people].
abstract: Stroke in the elderly has more major differences compared to young people: it is the first complication of atherothrombosis disease associated with the following risk factors: hypertension, diabetes, hypercholesterolemia, tobacco consumption and sleep apnea syndrome; AVC is the first consequence of atrial fibrillation; from a clinical point of view, seizure at the onset of the stroke is more frequent; prognosis is characterized by a high risk of dementia (20%); primary and secondary prevention is very efficacious even in very old patients, not only on the risk of stroke, but also on the risk of dementia; time trends at Dijon show a slight decrease of incidence rates of stroke only over 85 years, while prevention of stroke has taken advantage of real progress in precocious diagnosis and innovative treatments. In contrast, we observed a decrease of case-fatality rates at any day with a delay in age of onset of stroke, reaching five years in men and eight years in women, suggesting an increase of life expectancy without stroke, reflecting a certain efficacy of prevention.
