somnambulism

Full Definition

Somnambulism, commonly known as sleepwalking, is a parasomnia that occurs during slow-wave sleep phases of NREM sleep. Episodes typically involve walking or other complex behaviors performed while the individual remains asleep and unaware of their actions. The condition is more common in children and can pose safety risks requiring environmental modifications. Documentation in sleep medicine records requires careful description of episode frequency, duration, and associated behaviors.
