慢性缺血性脑病的发病情况及相关因素初探

目的探讨慢性缺血性脑病的发病情况及年龄、性别、生活嗜好、劳动方式的不同对该病的影响。方法对5400例具有头痛、头昏、睡眠不良、记忆力下降的患者作TCD检查，TCD异常＋症状诊为慢性缺血性脑病。结果诊为缺血性脑病者3198人，发生率为59．2％；在30至50岁组，男性发病明显多于女性（P〈0．05），脑、体力劳动者发病无显著性差异，在30岁前，烟酒嗜好者与非嗜好者发病无差异，30岁以后，二者间出现非常显著的差异。结论在有症状者中，慢性缺血性脑病的发生率较高（59．2％），峰值段女性激素可降低缺血性脑病的发生，脑体力劳动的差异不影响该病的发生，烟酒可致动脉硬化、缺血，但有一个量的积累及持续时间过程。
