procedure
Diagnosis of a circadian rhythm sleep disorder requires meeting three criteria: (1) a persistent or recurrent pattern of sleep disturbance due primarily to an alteration of the circadian timekeeping system or a misalignment between endogenous circadian rhythm and exogenous factors affecting sleep timing and duration; (2) the circadian-related disruption leads to insomnia, excessive sleepiness, or both; and (3) the sleep disturbance is associated with impairment of social, occupational, or other functions.
