Olfactory identification deficits (OIDs) are seen in schizophrenia, but it is unclear whether they are state- or trait-related.
We examined the prevalence of OIDs, as assessed by the University of Pennsylvania Smell Identification Test (UPSIT), and their correlations with prodromal symptoms in young relatives at risk for schizophrenia or schizoaffective disorder (HR-S).
UPSIT scores were lower in HR- S than in healthy controls, but were non-significant after covarying the effects of age, gender and IQ. OID deficits in HR-S were correlated, after covarying out the effects of age and IQ, with prodromal disorganisation.
The potential value of OID deficits as markers of psychopathological vulnerability in young relatives at risk for schizophrenia deserves further investigation.
精神分裂症患者存在嗅觉识别缺陷(OIDs),但尚不清楚这些缺陷是与状态相关还是与特质相关。
我们通过宾夕法尼亚大学嗅觉识别测试(UPSIT)评估了嗅觉识别缺陷的患病率,并研究了其与精神分裂症或分裂情感性障碍高危年轻亲属(HR-S)前驱症状的相关性。
HR-S组的UPSIT得分低于健康对照组,但在对年龄、性别和智商的影响进行协变量调整后,差异无统计学意义。在排除年龄和智商的影响后,HR-S组的嗅觉识别缺陷与前驱期的紊乱症状相关。
嗅觉识别缺陷作为精神分裂症高危年轻亲属心理病理易感性标志物的潜在价值值得进一步研究。
