定义
非24小时型睡眠-觉醒节律障碍的特点是，由于生物钟与 24 小时环境周期不一致，导致失眠和/或白天嗜睡与相对正常的睡眠交替出现。昼夜节律/睡眠-觉醒周期的时间长度通常超过 24 小时。当昼夜节律控制的睡眠-觉醒倾向与环境的昼夜周期相位循环时，就出现症状。这种疾病最常见于完全失明的患者。症状应持续至少数月，并导致严重的痛苦或精神、身体、社交、职业或学习障碍。
Non-24 hour sleep-wake rhythm disorder is characterised by periods of insomnia and/or daytime sleepiness, alternating with periods of relatively normal sleep, due to a lack of entrainment of the circadian clock to the 24-hour environmental cycle. The period length of the circadian/sleep-wake cycle is typically longer than 24 hours. Symptoms occur as the circadian-controlled sleep-wake propensity cycles in and out of phase with the environmental day-night cycle. The disorder is seen most commonly in individuals with complete blindness. The symptoms should have persisted for at least several months and result in significant distress or mental, physical, social, occupational or academic impairment.
