Sleepwalking (Causes)

Sleepwalking, or somnambulism, occurs most often in children 6 to 12 years old and is generally benign, although repeated episodes deserve investigation. The subject appears awake, but is not, and will not remember his actions.

In children, the cause is usually unknown but may also be related to fatigue, prior sleep loss, fever, or anxiety. In adults, sleepwalking is usually associated with a disorder of the mind but may also be seen with reactions to drugs and/or medications and alcohol, and medical conditions such as partial complex seizures. In the elderly, sleepwalking may be a symptom of an organic brain syndrome or REM behavior disorders.

Usually, no further examination and testing are necessary. If sleepwalking is frequent or persistent, examination to rule out other disorders (such as partial complex seizures) may be appropriate. It may also be appropriate to undergo a psychological evaluation to determine causes such as excessive anxiety or stress, or medical evaluation to rule out other causes.
