痴呆是由于脑功能障碍而产生的获得性智能损害综合征。脑血管性痴呆系与血管因素有关的痴呆。以往脑动脉硬化被认为是致病的主要因素,近年来大量研究证明多发性梗塞与皮层下动脉硬化性脑病为致病的主要因素。本文对150例血管性痴呆进行了临床与CT分析,报道如下。1 临床资料 1.1 一般资料 多发性梗塞性痴呆110例,男86例,女24例,年龄60～93岁,平均年龄71.2岁。皮层下动脉硬化性 Dementia is an acquired intellectual impairment syndrome that results from brain dysfunction. Cerebrovascular dementia is a vascular dementia. In the past, cerebral arteriosclerosis was considered as the main factor of pathogenicity. In recent years, a large number of studies have shown that multiple infarcts and subcortical arteriosclerotic encephalopathy are the main causative factors. 150 cases of vascular dementia clinical and CT analysis, reported as follows. 1 Clinical data 1.1 General Information 110 cases of multiple infarct dementia, 86 males and 24 females, aged 60 to 93 years, mean age 71.2 years. Subcortical arteriosclerosis
