Sleep terror disorder (pronounced: /sliːp 'terər dɪs'ɔːdər/), also known as Pavor nocturnus or Night terror, is a parasomnia disorder characterized by extreme terror and a temporary inability to regain full consciousness. The subject wakes abruptly from slow-wave sleep, with waking usually accompanied by gasping, moaning, or screaming. It is often also associated with sleepwalking.

Etymology

The term "Sleep terror disorder" is derived from the Latin word pavor meaning "fear" or "terror", and the Latin word nocturnus meaning "of the night". The term "disorder" is derived from the Old French desordre meaning "lack of order or sequence".

Symptoms

The primary symptom of sleep terror disorder is the occurrence of extreme panic and confusion during sleep, often accompanied by screaming and aggressive behavior. Other symptoms may include sweating, rapid heart rate, and dilated pupils. Unlike nightmares, individuals with sleep terror disorder usually do not recall the incident.

Causes

Sleep terror disorder is a parasomnia and is classified under the category of NREM sleep arousal disorders. It is often triggered by stress, sleep deprivation, or certain medications. It can also be associated with other mental health disorders such as post-traumatic stress disorder (PTSD) and panic disorder.

Treatment

Treatment for sleep terror disorder often involves addressing any underlying conditions or triggers. This may include stress management techniques, improving sleep hygiene, or medication in some cases. Cognitive behavioral therapy (CBT) is also often used.
