Overview of Sleep Problems

Learn about some common sleep disorders.

Is oversleeping getting in the way of your day? WebMD explains what can happen -- the physical side effects -- of getting too much sleep.

Snoring

Occasional snoring is usually not very serious and is mostly a nuisance for your bed partner. However, if you are a habitual snorer, you not only disrupt the sleep patterns of those close to you, but you also impair your own sleep quality.

Parasomnias

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.

Nightmares in Adults

When you wake up terrified from a disturbing nightmare, you might think you're the only adult who has them. After all, aren't adults supposed to outgrow nightmares?

Night Terrors

Night terrors in children are distinctly different from the much more common nightmares. Night terror symptoms are frequent and recurrent episodes of intense crying and fear during sleep, with difficulty arousing the child.

Obstructive Sleep Apnea

Here's information to help you understand how obstructive sleep apnea can affect your life and what can be done about it.

Central Sleep Apnea

In central sleep apnea, breathing is disrupted regularly during sleep because of the way the brain functions.

Insomnia

Insomnia is a sleep disorder that is characterized by difficulty falling and/or staying asleep.

Sleepwalking Symptoms

Bedwetting

While bedwetting can be a symptom of an underlying disease, a large majority of children who wet the bed have no underlying disease that explains their bedwetting.

Narcolepsy

Narcolepsy is a neurological disorder that affects the control of sleep and wakefulness

Teeth Grinding (Bruxism)

Occasional teeth grinding, medically called bruxism, does not usually cause harm, but when teeth grinding occurs on a regular basis, the teeth can be damaged and other complications can arise, such as jaw muscle discomfort or TMJ pain.

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" his or her 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.

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.

Sleep Paralysis

Have you ever felt like you were awake but unable to move? You might have even felt afraid but could not call for help? This condition is called sleep paralysis.

Sleep-Related Eating Disorders

Sleep-related eating disorders are characterized by abnormal eating patterns during the night.

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.
