The authors from Duke University Medical Center and Veterans Affairs Medical Center, Durham, NC, review the epidemiology, pathophysiology, diagnosis, and treatment of pediatric narcolepsy.
Narcolepsy is a disorder of rapid eye movement (REM) sleep characterized by excessive daytime somnolence and associated with sleep paralysis, hypnagogic (when falling asleep) and hypnopompic (when awakening) hallucinations, and cataplexy (temporary paralysis of cranial and somatic musculature).
