Sleep Disorders

A sleep disorder is a medical problem that in some way affects how you sleep. This section provides information on a large range of sleep disorders, from their symptoms, what causes them, and how they can be treated or reduced. There are two major types of sleep disorders; parasomnias and dyssomnias.

Parasomnia

Parasomnias are abnormal events or behaviours that mostly happen during sleep but can also occur just before you fall asleep or just after you wake up.
