The Different Types of 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.

Sleepwalking

Sleepwalking

Sleepwalking (also known as Somnambulism) is a strange but surprisingly common sleep disorder. Sleepwalkers can perform an array of complex daily tasks despite being fast asleep.

Nightmares

Nightmares

Night Terrors

A rare sleep disorder that enables people to fully act out their dreams in real life. Their dreams are vivid and intense, often involving a violent threat, causing them to run around the room kicking and punching.

Sleep Paralysis

Sleep Paralysis

To prevent us acting our dreams our bodies become paralysed when we go into REM sleep. But sometimes the paralysis works a little too well, kicking in before we've fallen asleep or continuing after we've woken up.

Restless Leg Syndrome

Restless Leg Syndrome: Symptoms, Causes & Treatment

People with restless leg syndrome experience a tingling, scratching, or crawling sensation in their legs that is only relieved by moving them. The feeling can be anything from a mild irritation to intolerable pain.

Dyssomnia

Dyssomnias are sleep disorders that affect the process of sleep, including how long you sleep for, the quality of sleep, and the timing of sleep.

Sleep Apnea

Sleep Apnea: Symptoms, Causes & Treatment

Narcolepsy

Narcolepsy

A neurological condition that's characterised by excessive daytime sleepiness, muscle weakness, and REM sleep complications such as sleep paralysis and hallucinations.

Fatal Familial Insomnia

An extremely rare sleep disorder affecting only a few families worldwide that slowly removes the ability to sleep until falling asleep becomes completely impossible.

Circadian Rhythm Disorder

Circadian rhythm disorders are problems that affect your sleep timing so that you can’t fall asleep until much later than you would like or fall asleep too early in the evening.
