Somnambulism
Sleepwalking. Purposeful moving, usually but not always including walking, while in a deep stage of sleep. Sleepwalking occurs most frequently in children, particularly boys. Sedatives tend to exacerbate rather than cure sleepwalking. The best measures are preventative: ensure that the sleepwalker is in a safe room for walking, and cannot accidentally fall through an open window or down stairs. Some types of sleepwalking are related to seizure disorders, bipolar disorders, or other neurological conditions, but most cases are transitory and due to unknown causes.
