目的 研究脑血管疾病（包括脑梗塞和脑出血）患者的认知功能障碍。方法 在微机上完成包括记忆、思维及认知速度的６项测验，比较研究了４５例脑血管疾病患者与５０例正常健康人认知功能的差异。结果脑血管疾病患者６项测验共７项指标（４项成绩和３项速度）结果均显著低于正常健康人，皮层病灶组全部测验结果又低于皮层下病灶组。结论脑血管疾病患者表现出明显的记忆和思维障碍、以及认知速度显著减慢，皮层病灶组上述认知功能障碍和速度减慢较皮层下病灶组严重。
Objective To study the cognitive dysfunction in patients with cerebrovascular disease (including cerebral infarction and cerebral hemorrhage). Methods Six tests including memory, thinking and speed of cognition were completed on a microcomputer, and the differences of cognitive function between 45 patients with cerebrovascular disease and 50 healthy controls were compared. Results Six of the six tests in patients with cerebrovascular disease showed significantly lower scores (four scores and three rates) than those in normal healthy subjects. All the results of cortical lesions were lower than those in subcortical lesions. Conclusions Patients with cerebrovascular disease showed obvious memory and thinking disorders, and the cognitive speed was significantly slowed down. The above cognitive impairment and speed of cortical lesions were more severe than those in subcortical lesions.
