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 alcohol use.
Symptoms
Night terrors are most common during the first third of the night, often between midnight and 2 a.m.
- Children often scream and are very frightened and confused. They thrash around violently and are often not aware of their surroundings.
- The child may not be able to respond to being talked to, comforted, or awakened.
-
The child may be sweating, breathing very fast (
hyperventilating
), have a
fast heart rate
, and widened (dilated) pupils.
Hyperventilating
Hyperventilation is rapid and deep breathing. It is also called overbreathing, and it may leave you feeling breathless.
Fast heart rate
A bounding pulse is a strong throbbing felt over one of the arteries in the body. It is due to a forceful heartbeat.
- The spell may last 10 to 20 minutes, then the child goes back to sleep.
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 .
Sleep walk
Sleepwalking is a disorder that occurs when people walk or do other activity while they are still asleep.
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.
Nightmares
A nightmare is a bad dream that brings out strong feelings of fear, terror, distress, or anxiety.
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 decrease after age 10.
