摘　　要：卒中是老年人死亡的主要原因,卒中后发生痴呆的风险增高.卒中后痴呆涵盖了卒中后的各种痴呆类型,是老年人致残的重要原因,其患病率在卒中后3个月至4年内为31.4%～21.5%,其发病率随卒中后时间的延长而增高.卒中和痴呆有许多共同的危险因素.卒中可以是痴呆的直接原因,也可能促进了变性性疾病的发展而引起痴呆.Stroke is a major cause of death in the elderly, and risk of dementia increases after stroke. Poststroke dementia （PSD） covers all types of dementia after stroke, and is an important cause of disability in the elderly. The prevalence of PSD varies from 31.4% to 21.5% in 3 months to 4 years after the stroke. Its incidence increases with time after the stroke. Stroke and dementia share a number of risk factors. Stroke can be the direct cause of dementia and may also produce dementia by precipitating the onset of degenerative disease.
