酒精所致精神和行为障碍患者脑电图分析

EEG analysis of patients with mental and behavioral disorders due to alcohol

目的：探讨酒精所致精神和行为障碍患者临床特征和脑电图的变化，为临床防治提供依据。方法对113例酒精所致精神和行为障碍患者的临床资料和脑电图检查结果进行回顾性分析。结果酒精所致精神和行为障碍患者多为男性体力劳动者，文化程度低，多伴有躯体疾病；脑电图轻度异常率83．2％、中度异常率9．7％、重度异常率2．7％；不同饮酒时间、日饮酒量及不同病程患者脑电图检查异常率比较差异有显著或极显著性（χ^2＝16．14、16．31、76．19，P＜0．05或0．01）。结论酒精所致精神和行为障碍患者多存在共病现象，脑电图异常率高，饮酒时间、饮酒量和病程对脑电图均有不同程度的影响。

Objective To explore clinical features and EEG changes of patients with mental and behavioral disorders due to alcohol（MBDA） in order to provide basis for clinical prevention and cure .Methods Ret-rospective analyses of clinical data and EEG results were conducted in 113 MBDA patients .Results MBDA patients were mainly male manual labourers and their educational background lower ,most of them were accompanied with somatopathy ;abnormal rate of mild EEG was 83 .2% ,moderate 9 .7% and severe 2 .7% ;there were significant or very significant differences in abnormal rate of EEG among patients with different drinking times ,daily capacities for liquor and courses of disease （χ^2 =16 .14 ,16 .31 ,76 .19;P〈0 .05 or 0 .01） .Conclusion MBDA patients have comorbid phenomenon and higher abnormal rate of EEG ;drinking time ,capacities for liquor and course of disease all have different degrees of influence on EEG .
