There are limited data on the neurocognitive correlates of childhood anxiety disorders. The objective of this study was to examine whether visual and verbal memory deficits of nonemotional stimuli are (1) a shared feature of three common childhood anxiety disorders (social phobia, separation anxiety disorder, and generalized anxiety disorder) or whether these deficits are restricted to specific anxiety disorders, and (2) present in offspring who possess at least one of the following established risk factors for anxiety disorders, parental history of panic disorder (PD), or major depressive disorder (MDD). One hundred and sixty offspring, ages 9-20 years, were recruited from parents with lifetime diagnoses of PD, MDD, PD plus MDD, or neither illness. Different clinicians blindly administered semistructured diagnostic interviews to offspring and parents. Verbal and visual memory subtests of the Wide Range Assessment of Memory and Learning were administered to offspring. The results showed that offspring with ongoing social phobia demonstrated reduced visual but not verbal memory scores compared to those without social phobia when controlling for offspring IQ, separation anxiety disorder, and generalized anxiety disorder. No other offspring anxiety disorder predicted memory performance. Neither parental PD nor parental MDD was associated with offspring memory performance. These findings are relevant to understanding the phenomenology of childhood anxiety disorders and may provide insights into the neural circuits underlying these disorders.
关于儿童焦虑症的神经认知相关性的数据有限。本研究的目的是检验非情感刺激的视觉和言语记忆缺陷是否(1)是三种常见儿童焦虑症(社交恐惧症、分离焦虑症和广泛性焦虑症)的共同特征,或者这些缺陷是否仅限于特定的焦虑症,以及(2)是否存在于具有以下至少一种既定焦虑症风险因素的后代中,即父母有惊恐障碍(PD)或重度抑郁症(MDD)病史。从有终生诊断为PD、MDD、PD加MDD或无任何疾病的父母那里招募了160名9至20岁的后代。不同的临床医生对后代和父母进行了盲法半结构化诊断访谈。对后代进行了广泛记忆与学习评估的言语和视觉记忆子测试。结果显示,在控制后代智商、分离焦虑症和广泛性焦虑症的情况下,与没有社交恐惧症的后代相比,患有持续性社交恐惧症的后代视觉记忆得分降低,但言语记忆得分未降低。没有其他后代焦虑症能预测记忆表现。父母的PD和MDD均与后代记忆表现无关。这些发现对于理解儿童焦虑症的现象学具有重要意义,并且可能为这些疾病背后的神经回路提供见解。
