Sleepwalking, also known as SOMNAMBULISM, is a disorder in which an individual walks or performs other activities while still asleep. It is a type of parasomnia, which is an abnormal behavior that occurs during sleep. Sleepwalking usually occurs during deep sleep and can last from a few seconds to 30 minutes. It is more common in children than adults, but can occur at any age. Symptoms may include talking, walking around, and performing complex activities such as cooking or driving. Treatment typically involves lifestyle changes and medications.
