O transtorno do ritmo sono-vigília não 24 horas é caracterizado por períodos de insônia e/ou sonolência diurna que se alternam com períodos de sono relativamente normal, devido à falta de sincronização do relógio circadiano com o ciclo ambiental de 24 horas. A duração do período do ciclo circadiano/sono-vigília é normalmente superior a 24 horas. Os sintomas ocorrem à medida que os ciclos de propensão sono-vigília controlados pelo circadiano entram e saem de fase com o ciclo ambiental dia-noite. O transtorno é visto mais comumente em indivíduos com cegueira completa. Os sintomas devem persistir por pelo menos vários meses e resultar em sofrimento significativo ou prejuízo mental, físico, social, ocupacional ou acadêmico. | |||

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. | |||
