[Epidemiology of Alzheimer disease and related disorders].
Alzheimer's disease and related disorders (dementia) are a major public health problem due to the number of cases in the general population, the projections for the future, and the consequences of these diseases. We can estimate that about 850 000 cases of dementia were present in France in 2005 and this number will increase to 1,200,000 in 2020 and 2,100,000 in 2040 if the incidence and the duration of the disease did not change. The development of prevention is therefore necessary. Four ways of prevention are credible. The most important is the treatment of vascular risk factors and particularly hypertension. Other ways are nutritional factors, stimulating leisure activities and depression.
