Somnambulism
Somnambulism
Somnambulism (pronounced: /sɒmˈnæmbjʊlɪzəm/), also known as sleepwalking, 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 "somnambulism" is derived from the Latin words "somnus" meaning "sleep" and "ambulare" meaning "to walk". Thus, it literally translates to "sleepwalking".
Symptoms
Symptoms of somnambulism include:
- Sleepwalking episodes
- Little or no memory of the event
- Difficulty waking the sleepwalker
- Inappropriate behavior such as urinating in closets (more common in children)
- Screaming (when sleepwalking occurs in conjunction with night terrors)
Causes
The exact cause of somnambulism is unknown, but it appears to have a genetic component. Other factors that may trigger an episode include lack of sleep, irregular sleep schedule, illness, stress, and certain medications.
Treatment
Treatment for somnambulism usually isn't necessary. However, if episodes lead to the potential for injury, are causing significant sleep disruption or result in embarrassment or distress, treatment may be needed. Treatment options include:
- Anticipatory awakenings
- Medications
- Hypnosis
- Cognitive behavioral therapy (CBT)
