摘要
目的 探讨脑白质疏松症在疾呆、脑血管病患者及正常老年人中的发生率、可能的发生机制和临床意义。方法 对既往住院的40例疾呆患者,240例脑血管病患者的影像资料进行了回顾性研究,并通过查体对60例正常老人进行头颅CT或MRI检查。结果 脑白质疏松症尽管可见于正常人,但更常见于疾呆及脑血管病患者,而且发生频率与年龄及脑血管病类型有关。结论 脑白质疏松是衰老过程的一部分,其发生机制与脑血流低灌注有关,它可能导致和加重智能障碍。
Objective To analyze the incidence,possible mechanism and clinical significance of leukoaraosis in patients with dementia or cerebral vascular disease (CVD) or in the healthy elderly. Methods Retrospective investigation on cranial CT or MRI was carried out in our 40 admitted cases with dementia,240 with CVD and 60 healthy elderly. Results Leukoaraosis was found to be more common in patients with dementia or CVD than in healthy elderly, and its occurrence was related to patient's age and pattern of CVD. Conclusion Leukoaraosis is a part of general aging process,its pathogenesis is possibly related to low perfusion of cerebral blood flow.This condition may lead to or deteriorate Intellectual disturbance.
