Factors that may increase the risk of sleepwalking include:

  • Genetics. Sleepwalking appears to run in families. It's more common if you have one parent who has a history of sleepwalking, and much more common if both parents have a history of the disorder.
  • Age. Sleepwalking occurs more often in children than adults, and onset in adulthood is more likely related to other health conditions.
