Risk Factors


Sleepwalking is more common in children and affects both boys and girls. It can begin as soon as a child is able to walk. The rate of it in children is as high as 17 percent. It peaks by the time they are eight to 12 years old. Most children with it also had confusional arousals at a younger age.

Rarely, sleepwalking may begin at any time in the adult life, even when someone is in their seventies. Up to 4 percent of adults sleepwalk. In adults, men are more likely to display aggressive behavior when they sleepwalk.
There is a strong genetic and family link to having it. Your chance of having it can double or almost triple if one of both parents had sleepwalking episodes as a child or adult.

Episodes of sleepwalking and sleep terrors share many of the same causes. These include the following:

  • Sleep deprivation
  • Hyperthyroidism (overproduction of thyroid hormones)
  • Migraine headaches
  • Head injury
  • Encephalitis (brain swelling)
  • Stroke
  • The premenstrual period
  • Bloated stomach
  • Physical or emotional stress
  • Obstructive sleep apnea (OSA)
  • Other sleep-related disorders or events
  • Travel
  • Sleeping in unfamiliar surroundings
  • Some medications
  • Alcohol use and abuse
  • Noise or light
  • Fevers in children
