Sleep-Related Breathing Disorders

Obstructive Sleep Apnea Disorder – this occurs when the upper airway is physically obstructed
Central Sleep Apnea Aisorder – this occurs when the brain doesn’t send proper signals to the muscles used to control breathing

Disorders of Hypersomnolence

These disorders are characterized by excessive daytime sleepiness and prolonged nighttime sleep. They include Narcolepsy types I & II, Hypersomnia (oversleeping), and Insufficient Sleep Syndrome (sleeping excessively but without feeling rested).

Circadian Rhythm Sleep/Wake Disorders

These disorders are characterized by daytime sleepiness, insomnia or both. Some Circadian rhythm sleep/wake disorders are Delayed Sleep Phase Syndrome, Advanced Sleep Phase Syndrome, Non-24 hour Sleep/Wake Syndrome, Irregular Sleep/Wake Rhythm, Shift-work Sleep Disorder and Jet Lag. (Jet lag occurs when the sleep/wake cycle is competing with the circadian rhythm while trying to adjust to a specific time zone)


PLMS (Characterized by periodic limb movements that prevent REM sleep by slightly arousing the sleeper throughout the night)

Sleep-Related Movement Disorders (Characterized by repetitive movements during sleep that causes full awakening)

Sleep Walking – Also known as Somnambulism, sleep walking involves walking around in a state of sleep.
