Night terror
Night terror
Night terror, also known as sleep terror (pronunciation: /naɪt 'tɛrər/), is a sleep disorder characterized by feelings of terror or dread, and typically occurs during the first hours of stage 3-4 non-rapid eye movement (NREM) sleep. Night terrors tend to happen during periods of arousal from delta sleep, also known as slow-wave sleep.
Etymology
The term "night terror" originates from the Latin words "nox" meaning night, and "terror" meaning fear or dread.
Symptoms
Symptoms of night terrors include screaming, intense fear and flailing while still asleep. Other symptoms can include sweating, heavy breathing, a racing pulse, and a sense of dread. Night terrors are usually paired with sleepwalking. Unlike nightmares, people do not usually remember the content of night terrors.
Causes
Night terrors can be caused by stress, depression, sleep deprivation, or certain medications. They are also common in children, with most cases occurring between the ages of three and twelve years old. However, adults can also experience night terrors, especially if they have a history of mood disorders, sleep disorders or substance abuse.
Treatment
Treatment for night terrors can include improving sleep hygiene, treating any underlying conditions, and in some cases, medication. Cognitive behavioral therapy (CBT) may also be beneficial.
