Question: I understand there are over eighty specific sleep disorders. What are they?Kevin’s ResponseThat’s right, there are over eighty different sleep disorders listed in the International Classification of Sleep Disorders (ICSD). They range from very prominent ones that affect a large number of people–such as sleep apnea, sleepwalking, and shift work sleep disorder–to far less common ones–such as Kleine-Levin syndrome (also known as Sleeping Beauty syndrome) and idiopathic insomnia–to sleep disorders that are associated with other medical conditions–such as sleep-related epilepsy and fibromyalgia.
The ICSD classifies all 80-plus disorders into three main categories–dyssomnias, parasomnias, and sleep disorders associated with medical/psychiatric disorders–as well as numerous subcategories (e.g. parasomnias associated with REM sleep).You can see a list of all the various types of sleep disorders, and the categories they are classified under, here.
