COMMON SLEEP DISORDERS

 

An Overview of Insomnia
Insomnia is a sleep disorder that is characterized by difficulty falling and/or staying asleep.
Hypersomnia (Daytime Sleepiness)
Hypersomnia, or excessive sleepiness, is a condition in which a person has trouble staying awake during the day. People who have hypersomnia can fall asleep at any time -- for instance, at work or while they are driving.
What Are Parasomnia?
Parasomnias are disruptive sleep disorders that can occur during arousals from REM sleep or partial arousals from non-REM sleep. Parasomnias include nightmares, night terrors, sleepwalking, confusional arousals, and many others.
REM Sleep Behavior Disorder
In a person with REM sleep behavior disorder (RBD), the paralysis that normally occurs during REM sleep is incomplete or absent, allowing the person to "act out" their dreams.
Circadian Rhythm Sleep Disorders
Circadian rhythm disorders are disruptions in a person's circadian rhythm -- a name given to the "internal body clock" that regulates the (approximately) 24-hour cycle of biological processes in animals and plants.
Non-24-Hour Sleep-Wake Disorder
Non-24-Hour Sleep-Wake Disorder is a specific kind of circadian rhythm disorder that is particularly common among blind people.  People with N24 may find themselves gradually going to bed later each night and waking up later each day until their sleep schedule gets flipped all the way around.
Periodic Limb Movement Disorder
Periodic limb movement disorder (PLMD) is a sleep disorder characterized by rhythmic movements of the limbs during sleep.
Shift Work Sleep Disorder
Shift work sleep disorder is trouble sleeping because you work nights or rotating shifts. You also may have this problem if you have trouble staying awake or alert when you are supposed to work your shift.
