老年人大多患有不同程度的心脑血管疾病。一过性脑缺血就是发病征兆之一,若能很好地了解、掌握和控制,则能有效地延缓脑部疾病的发生。据流行病学的一项调查显示,全国每年新发脑卒中人数约150万,每年死于脑卒中者约100万。全国约有几百万人因这样的疾病不能够正常地生活,从而给家庭和社会带来沉重的负担。患脑卒中的幸存者高达500万以上,其中75%不同程度地丧失了劳动能力,重度致残者约占40%以上。其实在脑卒中发生之前,有一个很明显的征兆就是一过性脑缺血。 Most elderly people with varying degrees of cardiovascular disease.

According to an epidemiological survey, the number of new strokes in the country is estimated at 1.5 million each year, and about 1 million people die each year from stroke. Some millions of people in the country can not live a normal life due to such diseases, thus placing a heavy burden on families and the community. Stroke survivors up to 5 million or more, of which 75% to varying degrees, lost their ability to work, severe disability accounted for about 40%.
