摘　　要：目的探索双相情感障碍(BD)的缓解期患者及其一级亲属认知损害和P300的异常特征及其关联。方法纳入2021年10月至2023年2月在厦门市仙岳医院精神医学科门诊及住院部的符合《精神障碍诊断与统计手册》第5版(DSM-Ⅴ)双相障碍Ⅰ型的诊断标准的缓解期患者40例,以及同期招募的41名未受影响的一级亲属组和35例健康对照组,采集所有受试者的人口学信息、临床资料以及认知功能评估和P3a/b振幅及潜伏期数据,比较三组间的认知功能及P3a/b成分的差异,并分析患者组异常的认知功能与P3a/b成分之间的关联。结果三组之间的P3a潜伏期、P3a振幅、P3b潜伏期和P3b振幅差异均有统计学意义(均P<0.05),BD患者P3a和P3b的潜伏期延长,振幅降低;三组之间数字符号测验、Stroop色词干扰测验(SCWT)-A和SCWT-C的得分差异有统计学意义均(P<0.05),而且在BD患者中,P3b潜伏期与SCWT-C得分呈负相关(r=﹣0.325,P<0.05)。结论双相情感障碍个体在缓解期间存在神经认知功能和P3a/b潜伏期和振幅异常,并且P3b潜伏期与异常认知之间的显著关联。Objective The aim is to explore the abnormal characteristics of cognitive impairment and P300 in individuals with BD in remission and theirfirst-degree relatives,and to examine the potential associations between P3a/b amplitudes and cognition.Methods Forty patients with bipolar disorder typeⅠwho met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders,the fifth edition(DSM-Ⅴ)in the outpatient and inpatient departments of the Department of Psychiatry at Xianyue Hospital in Xiamen from October 2021 to February 2023,as well as 41 unaffectedfirst-degree relatives and 35 healthy control groups recruited during the same period,were included.Demographic information,clinical data,cognitive function evaluation,P3a/b amplitude and latency data of all subjects were collected.The differences in cognitive function and P3a/b components among the three groups were compared,and the association between abnormal cognitive function and P3a/b components in the patient group was analyzed.Results The differences in P3a latency,P3a amplitude,P3b latency,and P3b amplitude among the three groups were statistically significant(all P<0.05).The latencies of P3a and P3b in BD patients were significantly prolonged,and the amplitudes were significantly reduced.There were significant differences in the scores of digit symbol test,Stroop color word test(SCWT)-A,and SCWT-C among the three groups(all P<0.05).Moreover,in BD patients,there was a significant negative correlation between P3b latency and SCWT-C score(r=-0.325,P<0.05).Conclusions Ourfindings revealed deficits in neurocognitive function as well as latency and amplitude deficits in P3a/b in individuals with BD during the remission phase.Moreover,a significant correlation was observed between P3b latency and abnormal cognition.
