脑外伤所致精神障碍司法鉴定400例分析

目的探讨精神疾病司法鉴定中颅脑损伤所致精神障碍的临床特征及相关因素。方法收集脑外伤后司法鉴定案例资料,按照神经外科GCS评分把脑损伤所致精神障碍鉴定案例分为重型(A组)、中型(B组)及轻型(C组)颅脑损伤;对案例的临床症状进行分析,根据中国精神障碍分类与诊断标准(第三版)(CCMD-3)进行精神障碍诊断,并探索临床症状与脑外伤程度之间的关系。结果轻、中度颅脑损伤所致精神障碍以器质性神经症样综合征最多见。重度颅脑损伤所致精神障碍中以智能损害综合征为多。三组间有显著性差异(P≤0.01)。结论在精神疾病司法鉴定中,不同严重程度的颅脑损伤所致的精神障碍有不同的临床特征。
