Night terror

Definition

Night terrors (sleep terrors) are a sleep disorder in which a person quickly wakes from sleep in a terrified state.

Alternative Names

Pavor nocturnus; Sleep terror disorder

Causes

The cause is unknown, but night terrors may be triggered by:

Night terrors are most common in children ages 3 through 7, and much less common after that. Night terrors may run in families. They can occur in adults, especially when there is emotional tension or the use of alcohol.

Symptoms

Night terrors are most common during the first third of the night, often between midnight and 2 a.m.

Most children are unable to explain what happened the next morning. They often have no memory of the event when they wake up the next day.

Children with night terrors may also sleep walk.

In contrast, nightmares are more common in the early morning. They may occur after someone watches frightening movies or TV shows, or has an emotional experience. A person may remember the details of a dream after waking up and will not be disoriented after the episode.

Exams and Tests

In many cases, no further examination or testing is needed. If the night terror is severe or prolonged, the child may need a psychological evaluation.

Treatment

In many cases, a child who has a night terror only needs to be comforted.

Reducing stress or using coping mechanisms may reduce night terrors. Talk therapy or counseling may be needed in some cases.

Medicines prescribed for use at bedtime will often reduce night terrors, but are rarely used to treat this disorder.

Outlook (Prognosis)

Most children outgrow night terrors. Episodes usually decreases after age 10.

When to Contact a Medical Professional

Call for an appointment with your health care provider if:

Prevention

Minimizing stress or using coping mechanisms may reduce night terrors.
