Abstract
Sleep disturbance contributes to impaired procedural learning in schizophrenia, yet little is known about this relationship prior to psychosis onset. Adolescents at ultra high-risk (UHR; N=62) for psychosis completed the Pittsburgh Sleep Quality Index (PSQI) and a procedural learning task (Pursuit Rotor). Increased self-reported problems with sleep latency, efficiency, and quality were associated with impaired procedural learning rate. Further, within-sample comparisons revealed that UHR youth reporting better sleep displayed a steeper learning curve than those with poorer sleep. Sleep disturbances appear to contribute to cognitive/motor deficits in the UHR period and may play a role in psychosis etiology.
摘要
睡眠障碍会导致精神分裂症患者程序性学习受损，但在精神病发作前，人们对此知之甚少。有精神病超高风险（UHR；N=62）的青少年完成了匹兹堡睡眠质量指数（PSQI）和程序性学习任务（追踪旋转器）。自我报告的入睡潜伏期、效率和质量问题增加与程序性学习率受损有关。此外，样本内比较显示，报告睡眠质量较好的 UHR 青少年的学习曲线比睡眠质量较差的青少年更为陡峭。睡眠障碍似乎会导致 UHR 期间的认知/运动缺陷，并可能在精神病发病机制中发挥作用。
