脑电图在精神科的临床应用

脑电图技术在精神科临床应用主要有以下几方面：1.精神心理障碍性疾病诊断与鉴别诊断的辅助依据：（1）功能性与器质性精神障碍的鉴别,如精神障碍为首发症状的脑炎,癫癎所致精神障碍,脑卒中后抑郁障碍、慢性酒精依赖性脑病、煤气中毒迟发性脑病、毒鼠强中毒性脑病、阿尔茨海默病、精神发育迟滞、睡眠障碍性疾病、酒精海洛因依赖、肝/肺/肾性脑病。（2）发作性精神行为障碍与癫癎精神运动性发作、癫癎性精神障碍以及非惊厥性癫癎持续状态的鉴别诊断;精神障碍的司法鉴定。（3）睡眠障碍性疾病的诊断与鉴别诊断。2.辅助评估脑认知功能障碍：精神发育迟滞、精神疾病患者伴认知功能障碍、抗精神病药物对认知功能的损害。3.精神科用药的辅助监测：监测EEG变化有助于指导剂量调整和药物种类选择,避免第Ⅰ代抗精神病药与三环类抗抑郁药的使用过量和疗程过长引起EEG慢波化异常甚至出现癫癎样波发放。避免催眠镇静药物（如苯二氮卓类、巴比妥类）过量可引起脑电背景活动弥漫性快波分布与嗜睡、记忆力下降。
