Sleepwalking

Disease Description (Causes and Symptoms)

• Definition: Sleepwalking (somnambulism) is an NREM parasomnia in which a person gets out of bed and walks around or performs repetitive behaviors while in a state of partial arousal from sleep.
• Causes·pathophysiology: Associated with genetic predisposition and sleep architecture (increased deep non-REM sleep). In children, it is often a physiological phenomenon related to brain maturation, while in adults it may result from multiple factors, including stress, sleep deprivation, alcohol·medications (some sedatives·antidepressants)·fatigue, and underlying sleep apnea·seizures.
• Main symptoms: Getting out of bed and walking, opening doors, fidgeting with clothes, eating, and other repetitive behaviors within 1–3 hours after sleep onset; a blank stare; and loss of memory of the day’s behaviors after awakening. When the duration·frequency is severe, it may cause impaired daily functioning and safety problems.

Treatment Methods

• Nonpharmacological treatment (first-line)
  • Ensure safety: Remove dangerous objects around the bed, lock windows·doors, do not sleep in high places, and put away electronic devices·sharp objects.
  • Behavioral therapy: Improve sleep hygiene (regular sleep·adequate sleep duration), manage stress, relaxation training, cognitive behavioral techniques, and scheduled awakening in children (waking the child 15–30 minutes before the expected time of sleepwalking to reset the sleep cycle).
  • Family education: Do not forcibly awaken the patient; calmly and safely guide them back to sleep.
• Pharmacological treatment
  • Adults·dangerous cases: Benzodiazepines (e.g., clonazepam) often improve symptoms by reducing deep non-REM sleep. Start at a low dose for a short period and adjust as needed.
  • Children: Since it is usually temporary, pharmacological treatment is limited. A specialist should make a careful decision when symptoms are severe or dangerous behaviors are present.
  • Other medications: Treatment according to the cause (e.g., sleep apnea, anxiety, depression) (respiratory treatment, adjustment of antidepressants, etc.).
• Additional evaluation and procedures
  • When symptoms are frequent or there is trauma·atypical symptoms (daytime confusion, preserved memory, suspected seizures), differentiate conditions such as epilepsy using polysomnography (PSG)·electroencephalography (EEG).
• Precautions·prevention of complications
  • Avoid alcohol·excessive use of sleeping pills and sleep deprivation.
  • Forced awakening may trigger aggression → Safely guide the person back to sleep.
  • Complications: Physical trauma, daytime sleepiness·reduced concentration due to poor sleep quality, risk of accidents (driving·machinery), and possible legal problems.

Checklist Before an Outpatient Visit (Including Sample Questions)

• Items and records to prepare
  • List of medications currently being taken (including prescription·OTC·sleeping pills·antidepressants·sedatives)
  • Record of alcohol·caffeine intake and sleep habits (bedtime·wake-up time)
  • Sleepwalking symptom diary: time of occurrence, duration, behaviors (opening doors·leaving the house, etc.), frequency, and triggers (stress·sleep deprivation·alcohol consumption)
  • Whether accidents·injuries have occurred, family history (history of sleep disorders)
  • Symptom video, if possible (recorded on a mobile phone)
  • Previous test results (EEG, polysomnography, etc.) or psychiatry·neurology medical records
• Sample questions (to provide to the doctor)
  • "In what situations is it more dangerous when the symptoms occur?"
  • "Could medications I regularly take (e.g., antidepressants) have an effect?"

Examples of General Questions to Ask the Doctor

• "What do you think is causing this condition? Will additional tests (polysomnography, EEG) be needed?"
• "What are the effects and side effects of the recommended treatment (nonpharmacological·pharmacological)?"
• "How long do you expect the treatment to take? How likely is recurrence?"
• "Are there any lifestyle changes I should make immediately?"

Examples of Condition-Specific Questions

• "There is a risk that I may leave the house or go outside while sleepwalking at night. What safety measures should I prioritize?"
• "If symptoms suddenly begin in an adult, should underlying conditions such as epilepsy or sleep apnea be evaluated? What tests do you recommend?"
