Sleepwalking
Sleepwalking
Sleepwalking, also known as somnambulism (pronunciation: /ˌsɒmnæmˈbʊlɪzəm/), is a behavior disorder that originates during deep sleep and results in walking or performing other complex behaviors while asleep. It is much more common in children than adults and is more likely to occur if a person is sleep deprived.
Etymology
The term "sleepwalking" is derived from the words "sleep" and "walking", which describe the condition's main features. The term "somnambulism" is derived from the Latin "somnus" meaning "sleep", and "ambulare", meaning "to walk".
Symptoms
Sleepwalking is characterized by a series of behaviors that are performed during a partial arousal from deep sleep. This includes:
- Walking during sleep
- Little or no memory of the event
- Difficulty arousing the sleepwalker during an episode
- Inappropriate behavior such as urinating in closets (more common in children)
- Screaming (when sleepwalking occurs in conjunction with sleep terrors)
Causes
The cause of sleepwalking is unknown, but it appears to have a genetic component. Certain factors may increase the likelihood of sleepwalking, including:
- Sleep deprivation
- Chaotic sleep schedules
- Stress
- Alcohol intoxication
- Drugs such as sedative/hypnotics (drugs that promote or extend sleep), neuroleptics (drugs used to treat psychosis), stimulants (drugs that increase activity), and antihistamines (drugs used to treat symptoms of allergies)
Treatment
Treatment for sleepwalking generally isn't necessary. In most cases, a sleepwalker doesn't need treatment. However, you might need to talk to a doctor if the sleepwalking episodes:
- Occur often — for example, more than one or two times a week
- Lead to dangerous behavior or injury
- Cause significant sleep disruption or daytime fatigue
- Result in embarrassment or disrupt others' sleep
