Educational Objectives

Upon completion of this activity, participants will be better prepared to:

  • Diagnose non-24–hour sleep-wake disorder based on presenting symptoms, a comprehensive sleep history, and published diagnostic criteria
  • Tailor therapeutic regimens for patients with non-24–hour sleep-wake disorder, including appropriate combinations of nonpharmacologic and pharmacologic modalities
  • Educate patients with non-24–hour sleep-wake disorder on the deleterious effects of disrupted circadian rhythms, behavioral management strategies, and pharmacologic treatment options

Target Audience

The educational design of this activity addresses the needs of primary care providers (PCPs), sleep specialists, and other clinicians involved in the identification and ongoing treatment of patients with non-24–hour sleep-wake disorder (non-24 disorder).

Statement of Need/Program Overview

Non-24 disorder is characterized by complaints of insomnia and/or excessive daytime sleepiness that result from a progressive desynchronization of the earth’s usual 24-hour light/dark cycle and the individual’s endogenous circadian rhythms.1,2 As many as half of totally blind patients suffer from non-24 disorder, and the incidence of non-24 disorder also appears to be more common than previously appreciated in sighted individuals in their teens and 20s.3,4 Non-24 disorder is underdiagnosed, in part because patients do not proactively discuss sleep-related issues with their healthcare providers, and time-limited clinicians often do not regularly inquire about insomnia or excessive sleepiness.5,6 Moreover, until recently, treatment recommendations were largely based on case series and clinical experience rather than well-designed clinical trials.6,7 This case-based POC101 program will educate clinician-learners regarding the pathophysiologic basis of non-24 disorder, current diagnostic criteria, behavioral approaches to improving sleep hygiene and daily scheduling, and evidence-based pharmacologic interventions.
