Sleepwalking, also called somnambulism, usually occurs during the first third of the night, and the duration of each episode can range from a few minutes to a half-hour. There is some evidence that sleepwalking is genetically linked, occurring most commonly in children aged six to 12. Boys are more likely than girls to sleepwalk. If the sleepwalking begins by age nine, the sleepwalker may continue to sleepwalk as an adult. Other adult sleepwalkers may be experiencing personality conflict or anxiety.

Sleepwalking itself is not considered medically dangerous, but the sleepwalker may be injured by falling or tripping, going outside the house or even causing a car accident while driving. Experts advise seeking medical help if the sleepwalker is having frequent episodes or is walking outside the house.

Sleepwalking Symptoms

• Walking, sometimes performing other activities such as going to the bathroom, opening closet doors and so on, while asleep
• While sleepwalking, the patient has eyes opened and a dazed facial expression
• Confusion or disorientation when awakened

Sleepwalking Treatment Options

• Making the house safe for the sleepwalker, including blocking the top of staircases with a gate and removing objects the sleepwalker might trip over
• Calming bedtime rituals, such as meditation or relaxation exercises
• Avoiding fatigue—being overtired can trigger sleepwalking
• For more severe cases, short-acting tranquilizers may be prescribed
