Definition of Sleep disorders
Sleep disorders: Any disorder that affects, disrupts, or involves sleep. The most common sleep disorder is probably snoring, although it is usually not medically significant. Insomnia, sleep apnea, restless leg syndrome, and sleepwalking are also sleep disorders. Most large medical centers have diagnostic and treatment facilities dedicated to sleep disorders. See also sleep apnea, sleepwalking, snoring. Last Editorial Review: 4/27/2011 5:27:15 PM Back to MedTerms online medical dictionary A-Z List
