What is the cause of sonamnambulism? Is it considered a disease?

Answer

Merriam-Webster Online Dictionary defines “somnambulism as an abnormal condition of sleep in which motor acts (as walking) are performed”.

According to another definition “somnambulism is a series of complex behaviours that are initiated during slow wave sleep and result in walking in the sleep”.

About 18 % of the population is prone to sleepwalking, children more often than adults and boys more often than girls. Sleepwalking may have a genetic tendency.

For some, the sleepwalking episodes happen less than once a month and don’t do any harm either to the patient himself or the others. In the most severe forms the episodes occur almost nightly or are associated with physical injury. It’s important that a chronic sleepwalker seeks professional help.
