首发精神分裂症患者认知功能研究

目的:了解首发精神分裂症患者认知功能损害特点以及治疗对认知功能的影响。方法:对37例符合中国精神障碍分类与诊断标准第3版首发精神分裂症诊断标准的患者于治疗前及治疗8周后采用华文认知能力量表(CCAS)、阳性与阴性症状量表(PANSS)进行评定;同时调查患者的临床特征。结果:精神分裂症患者治疗后CCAS工作记忆(t=3.315,P<0.01)、学习能力(t=4.726,P<0.01)、推理能力(t=4.209,P<0.01)、加工速度(t=6.253,P<0.01)、空间/计算(t=5.111,P<0.01)等认知功能和言语智商(t=3.769,P<0.01)、操作智商(t=3.552,P<0.01)以及总智商(t=3.972,P<0.01)均较治疗前有不同程度提高;治疗前后比较差异均有统计学意义。经Pearson相关分析,治疗前后总智商的差值与PANSS总分及阳性总分差值具有相关性(r分别=0.564、0.756,P<0.05)。结论:首发精神分裂症患者在发病初期就存在认知功能损害;奥氮平等药对精神分裂症的认知损害具有一定改善作用,短时记忆某些成份的改善与精神症状(阳性症状)的好转具有相关性。
