A pictorial representation of the most recent clinical practice guideline recommendations for treatment of the treatment of intrinsic circadian rhythm sleep-wake disorders. From top down is Advanced Sleep-Wake Phase Disorder, Delayed Sleep-Wake Phase Disorder, Non-24 Hour Sleep-Wake Disorder in the blind with circadian period >24 hours, Non-24 Hour Sleep-Wake Disorder in the blind with circadian period <24 hours, Irregular Sleep-Wake Disorder for the elderly, and Irregular Sleep-Wake Disorder for children. The times in red indicate the range in typical fall asleep or wake times seen in patients prior to treatment, and the red arrow represents the direction of desired phase shifts. The light bulb symbol represents light therapy. The circles represent melatonin pills with doses suggested by the authors to either minimize or maximize melatonin’s soporific effect as needed.
