脑梗塞后智能障碍影响因素分析

目的：探讨影响脑梗塞后智能障碍的因素。方法：应用长谷川痴呆量表对249例经CT证实的脑梗塞患者进行智测评，评分0－21．5为智能障碍组，22－32．5为正常组，探讨智能障碍的发生与性别，年龄，文化程度，卒中主要危险因素（高血压和糖尿病）、梗塞灶数量及体积，以及脑萎缩和脑白质疏松之间的相互关系。结果：249例脑梗塞患者中有106例（42．6％）出现智能障碍。年龄、性别、文化程度、高血压病，糖尿病与智能的发生有关；梗塞灶的数量越多，体积越大其智能障碍发生率越高；脑萎缩及脑白质质疏松与智能障碍关系密切。结论：脑梗塞后智能障碍是多因素相互作用的结果，与梗塞灶数量，体积、脑萎缩及脑白质疏松等多种因素有关。

A study on the effect factors of intelligence impairment in cerebral infarct patients

Objective To explore the effect factors of intelligence impairment in cerebral infarct patients. Methods The intelligence levels of 249 cases of cerebral infarct patients identified by CT findings were tested by Hasegawa Dementia Scale.To analyze the correlation among the occurrence of intellectual impairment and sex,age,education level,the major risk of stroke(hypertension and diabetes),the quantity and extent of focal lesions and the pressense of cerebral atrophy or subcortical degeneration in 106 cerebral infarct dementia index cases and 143 cerebral infarction without dementia index cases.Results 106 (42.6% ) of the cerebral infarction patients were shown to have intelligence impairment,including dementia(24.9%)and pre-dementia(17.7%).The intellectual impairment was relative to age,sex ,education level,the major risk of stroke,cerebral atrophy,subcortical degeneration and the quantity and extent of focal lesion.Conclusions It was suggested that a single explanation for cerebral infarct impairment is not adequate,multiple factors including quantity and extent of focal lesions,pathologic changes of cerebral atrophy,subcortical chronic brain circulation disorder,low education level and so on may independently contribute to cerebral infarct intellectual impairment.
