Sleepwalking — also known as somnambulism — involves getting up and walking around while in a state of sleep. More common in children than adults, sleepwalking is usually outgrown by the teen years. Isolated incidents of sleepwalking often don't signal any serious problems or require treatment. However, recurrent sleepwalking may suggest an underlying sleep disorder.
Sleepwalking in adults has a higher chance of being confused with or coexisting with other sleep disorders as well as medical conditions.
If anyone in your household sleepwalks, it's important to protect him or her from potential injuries related to sleepwalking.
