Sleep and circadian variability in people with delayed sleep-wake phase disorder versus healthy controls.

ABSTRACT:

Objective/background

To compare sleep and circadian variability in adults with delayed sleep-wake phase disorder (DSWPD) to healthy controls.

Patients/methods

Forty participants (22 DSWPD, 18 healthy controls) completed a ten-day protocol, consisting of DLMO assessments on two consecutive nights, a five-day study break, followed by two more DLMO assessments. All participants were instructed to sleep within one hour of their self-reported average sleep schedule for the last four days of the study break. We analyzed the participants' wrist actigraphy data during these four days to examine intraindividual variability in sleep timing, duration and efficiency. We also examined shifts in the DLMO from before and after the study break.
