Sleep Disorders

Sleep Disorders are medical disorders that affect an individual’s sleep patterns and encompass a wide-variety of disorders.  There are dozens of sleep disorders; the most common sleep disorders are listed below.

Circadian Rhythm Sleep Disorder – Circadian rhythm refers to a person’s internal sleep and wake rhythms that occur during a 24-hour period. A circadian rhythm sleep disorder is a recurring pattern of sleep disruption resulting either from an altered sleep-wake schedule or an inequality between a person’s natural sleep-wake cycle and the sleep-relate demands placed on him or her.
