But if your child has ever had what's known as a night terror or sleep terror , his or her fear was likely inconsolable, no matter what you tried. A night terror is a sleep disruption that seems similar to a nightmare , but is far more dramatic. Though night terrors can be alarming for parents who witness them, they're not usually cause for concern or a sign of a deeper medical issue. Unlike nightmares, which kids often remember, kids won't have any memory of a night terror the next day because they were in deep sleep when it happened — and there are no mental images to recall.

Night terrors are caused by over-arousal of the central nervous system CNS during sleep. Sleep happens in several stages. We have dreams — including nightmares — during the rapid eye movement REM stage. The researchers found that a person is significantly more likely to experience night terrors if their identical twin does. In non-identical twins, the chance of this happening is lower. A long-term study of 1, children, published in , found that those whose parents had walked in their sleep were more likely to have night terrors and that these night terrors were more likely to persist for longer.

The peak age for night terrors in childhood was found to be 18 months. At this age, Up to a third of children who experienced night terrors then develop sleepwalking habits later in childhood. A doctor will ask a patient and, if appropriate, family members, about any signs of night terrors.

They may also carry out tests to look for other possible factors, which may be physical or psychological. A sleep study, or polysomnography, involves spending the night in a sleep laboratory and having various measurements taken while sleeping.

Brain waves, blood oxygen levels, heart rate, breathing, and eye and leg movements are measured throughout the night, and the patient is filmed. The film may reveal irregular breathing, possibly suggesting apnea, or other reasons for a disturbed sleep, such as restless leg syndrome. Although the night terrors appear distressing for children, any permanent harm is unlikely, and they usually pass without intervention.

Treatment is normally necessary only if the episodes are having a significant negative effect on the safety of the person or their family, or if the problem is affecting their ability to function during the day.

Close and lock all doors and windows at night. Consider alarming them. Remove trip hazards and remove fragile and dangerous objects. Identify any sources of stress and ways to relieve them. If a child is experiencing night terrors, ask them to tell you about anything that is bothering them and talk it through. Sleep deprivation can be a factor, so try going to bed earlier or fitting in an afternoon nap.

Having a relaxing routine before bedtime can also help, for example, a warm bath or light reading before sleep. Accessed May 9, Rochester, Minn. Kotagal S. Sleepwalking and other parasomnias in children.
