季节性情感障碍 (SAD) 患者的睡眠主要特点是睡眠时间延迟和嗜睡的自我报告。目前尚不清楚睡眠时间延迟是否是由于昼夜节律或行为失调所致，以及有效的治疗是否独立于昼夜节律系统。 SAD 的自我报告和活动记录/多导睡眠图睡眠持续时间之间的差异阻碍了对嗜睡作为主要症状的澄清。之前的研究在很大程度上忽略了季节性抑郁症的夏季缓解期，这可能会对睡眠障碍在冬季抑郁发作和复发中所起的作用产生有价值的见解。未来的研究应结合对睡眠和昼夜节律的多方法、多季节评估，以最好地表征相关的睡眠昼夜节律表型。凭经验确定 SAD 中存在的睡眠表型将为有针对性的睡眠干预铺平道路。
Sleep in seasonal affective disorder (SAD) has been primarily characterized by delayed sleep timing and self-reports of hypersomnolence. It is unclear whether delayed sleep timing is due to circadian or behavioral misalignment and if effective treatments operate independently of the circadian system. Discrepancies between self-report and actigraphic/polysomnographic sleep duration in SAD hinder clarification of hypersomnolence as a cardinal symptom. Previous studies have largely neglected the summer remission period in SAD, which could yield valuable insight to the role sleep disturbances play in the onset and recurrence of winter depressive episodes. Future studies should incorporate multi-method, multi-season assessment of sleep and circadian rhythms to best characterize relevant sleep-circadian phenotypes. Empirically determining sleep phenotypes present in SAD will pave the way for targeted sleep interventions.
