脑卒中后发生痴呆的相关危险因素特征

Characteristics of stroke-related risk factors for vascular dementia

目的:探讨脑血管病致痴呆的相关危险因素。方法:137例脑卒中患者在入院时均进临床和智能评定、血生化及头颅CT或MRI检查,并把痴呆者与非痴呆者的临床表现,伴发疾病,脑卒中性质、部位等进行对比分析。结果:血管性痴呆(vasculardementia,VD)的发生率为31.3%(43/137),年龄越大、文化程度越低痴呆的发生率越高,脑卒中次数越多、面积越大、神经功能缺损严重,高血压、高血糖、高血脂、心脏疾病患者痴呆的发生率也明显升高。结论:脑卒中后常并发痴呆,痴呆的发生受多种因素相互影响的结果,它与年龄、低文化、脑卒中次数、面积、部位、神经功能缺损严重程度有密切关系。

AIM:To explore the related risk factors of cerebrovascular disease induced dem entia. METHODS:One hundred and thirty-seven stroke patients received clinical and in telligent evaluation at admission, and examination of CT or MRI. Clinical situat ion,complication, stroke kind and site were compared between the subjects with a nd without dementia. RESULTS:The incidence of vascular dementia(VD) was 31.3%(43/137),With aging and lower educational level,the patients had more times of cerebral seizures,big ger area,more severe neurological function, and a higher incidence of dementia w as also found in the patients with hypertension,hyperglycemia,hyperlipidemia and heart disease. CONCLUSION:Post-stroke dementia,due to the interaction among multiple factors ,is closely correlated with age,low educational background,amount of cerebral se izures, area, site and severity of neurological impairment.
