Program Title: Circadian Rhythm Sleep Disorders
Faculty Presenter: Mary Ellen Wells
Course Description: Circadian Rhythm Sleep Disorders are defined as “a persistent or recurrent
pattern of sleep disturbance” due primarily to “alterations of the circadian timing system”, or
“misalignment between the endogenous circadian rhythm and exogenous factors that affect the timing
or duration of sleep”, according to the International Classification of Sleep Disorders published by the
American Academy of Sleep Medicine. This webinar discusses several of these disorders including
Delayed sleep phase disorder, advanced sleep phase disorder, irregular sleep-wake rhythm, nonentrained type or 24-hour sleep-wake syndrome, jet lag and shift-work disorder. Topics include
symptoms, pathophysiology, diagnostic criteria, treatment options, and preventative measures.
