Sleepwalking (somnambulism) is a type of sleep disorder called a parasomnia, which refers to undesirable physical events (movements or behaviors) or experiences (emotions, perceptions, dreams) that occur during sleep.
Sleepwalking is not a mental disorder.

What Causes Sleepwalking (Somnambulism)?
Causes of sleepwalking (somnambulism) include:
- Sleep deprivation
- Overactive thyroid (hyperthyroidism)
- Physical or emotional stress
- Migraines
- Abdominal bloating
- Head injury
- Brain swelling (encephalitis)

- Post-traumatic stress disorder (PTSD)
- Other medical disorders, such as congestive heart failure and Parkinson’s disease
How Is Sleepwalking (Somnambulism) Diagnosed?
Sleep disorders are diagnosed with a patient history and physical exam. Tests or procedures that may be used to diagnose sleep disorders or to rule out other underlying conditions include:
- Daily sleep log
- Sleep study (polysomnography)
- Record of activity and movement with a monitor or motion detector, generally worn on the wrist throughout the day and night (actigraphy)
- Core body temperature measurements
- Hormone tests
- Electrocardiogram (“ECG”)
- Computerized tomography (CT) scan
- Magnetic resonance imaging (MRI) of the brain
What Is the Treatment for Sleepwalking (Somnambulism)?
Sleepwalking in children often goes away on its own as children enter adolescence and the teen years. Until then, it is important to create a safe environment so the child does not get injured while sleepwalking.
- Remove clutter or other tripping hazards that could cause a child to trip and fall
- Install a safety gate in the doorway of the child’s bedroom or at the top of the stairs
- Lock windows and doors at night so a child cannot get outside
- Children should not sleep in an elevated bed (bunk bed)
- Keep sharp objects or weapons locked away and out of reach
- Install lights with motion sensors
- Consider use of door alarms or a bed alarm that goes off if a person gets out of bed
Treatment for sleepwalking includes:
- Improve sleep hygiene to get adequate sleep
- Treat other sleep problems, such as sleep apnea or restless leg syndrome
- Education to avoid triggers
- Cognitive behavioral therapy (CBT)
- Relaxation techniques for stress-related episodes of sleepwalking
- Medication
- Benzodiazepines
- Antidepressants
- Melatonin
