目的:探讨老年人脑梗塞和再发脑梗塞后致残与痴呆机率。方法 :随访100例脑梗塞后遗症致残与痴呆患者 ,进行统计学处理与分析。结果 :再发脑梗塞机体致残与痴呆率均大于首发脑梗塞 ,随发病次数的增多 ,后遗症加重。结论 :脑梗塞与再发脑梗塞的部位、面积大小、发作次数、相关疾病诱发关系与致残、痴呆率呈正相关 Objective: To investigate the incidence of disability and dementia after cerebral infarction and recurrent cerebral infarction in the elderly. Methods: 100 patients with cerebral infarction sequelae and dementia were followed up for statistical analysis and treatment. Results: The rates of disability and dementia in recurrent cerebral infarction were higher than those in the first cerebral infarction. With the increase of the number of onset, sequelae increased. CONCLUSIONS: There was a positive correlation between the infarction size and the area, the size of the infarction, the number of seizures and the related disease-induced relationship with disability and dementia
