Overview
Sleepwalking is a disorder that occurs when people walk or do an other activity while they are still asleep.

What are the symptoms of Sleep walking?

 * When people sleepwalk, they may sit up and look as though they are awake when they are actually asleep. They may get up and walk around, or do complex activities such as moving furniture, going to the bathroom, and dressing or undressing. Some people even drive a car while they are asleep.


 * The episode can be very brief (a few seconds or minutes) or it can last for 30 minutes or longer, but most episodes last for less than 10 minutes. If they are not disturbed, sleepwalkers will go back to sleep. However, they may fall asleep in a different or even unusual place.


 * Symptoms of sleepwalking include:
 * Acting confused or disoriented when they wake up
 * Having blank look on face
 * Opening eyes during sleep
 * Not remembering the sleep walking episode when they wake up
 * Performing detailed activity of any type during sleep
 * Rarely, showing aggressive behavior when they are woken up by someone else
 * Sitting up and appearing awake during sleep
 * Taking in sleep and saying things that do not make sense
 * Walking during sleep
 * Taking in sleep and saying things that do not make sense

What causes Sleep walking?

 * The normal sleep cycle has distinct stages, from light drowsiness to deep sleep. During rapid eye movement (REM) sleep, the eyes move quickly and vivid dreaming is most common.


 * Each night people go through several cycles of non-REM and REM sleep. Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (stage 3 or stage 4 sleep) early in the night. If it occurs during REM sleep, it is part of REM behavior disorder and tends to happen near morning.


 * The cause of sleepwalking in children is usually unknown. Fatigue, lack of sleep, and anxiety are all associated with sleepwalking.


 * In adults, sleepwalking may occur with:
 * Alcohol, sedatives, or other medication
 * Medical conditions, such as partial complex seizures
 * Mental disorders


 * In the elderly, sleepwalking may be a symptom of an organic brain syndrome or REM behavior disorders.


 * Sleepwalking can occur at any age, but it happens most often in children ages 5 - 12. It appears to run in families.

When to seek urgent medical care?
You probably won't need to visit your health care provider if you are sleepwalking. However, discuss the condition with your doctor if:
 * You also have other symptoms
 * Sleepwalking is frequent or persistent
 * You perform potentially dangerous activities (such as driving) while sleepwalking

Diagnosis

 * Usually, people do not need further examinations and testing.


 * If the sleepwalking occurs often, the doctor may do an exam or tests to rule out other disorders (such as partial complex seizures).


 * If you have a history of emotional problems, you also may need to have a psychological evaluation to look for causes such as excessive anxiety or stress.

Treatment options

 * Some people mistakenly believe that a sleepwalker should not be awakened. It is not dangerous to awaken a sleepwalker, although it is common for the person to be confused or disoriented for a short time when they wake up.


 * Another misconception is that a person cannot be injured while sleepwalking. Sleepwalkers are commonly injured when they trip and lose their balance.


 * Most people don't need any specific treatment for sleepwalking.


 * Safety measures may be needed to prevent injury. This may include moving objects such as electrical cords or furniture to reduce the chances of tripping and falling. You may need to block off stairways with a gate.


 * In some cases, short-acting tranquilizers have been helpful in reducing sleepwalking episodes.

What to expect (Outlook/Prognosis)?

 * Sleepwalking usually decreases as children get older.


 * It usually does not indicate a serious disorder, although it can be a symptom of other disorders.


 * It is unusual for sleepwalkers to perform activities that are dangerous. However, you may need to take care to prevent injuries such as falling down stairs or climbing out of a window.

Possible complications
The main complication is getting injured while sleepwalking.

Prevention

 * Avoid the use of alcohol or central nervous system depressants if you sleepwalk.
 * Avoid getting too tired and try to prevent insomnia, because this can trigger a sleepwalking episode.
 * Avoid or minimize stress, anxiety, and conflict, which can worsen the condition.
