Night Terrors


Childhood night terrors are a parasomnia, or partial-sleep disorder, common in young children. They occur in the deepest stage of sleep and are characterized by an abrupt arousal, usually within the first hour of sleep. The child may sit bolt upright in acute terror, screaming inconsolably. Night terrors are a confusional arousal resulting from immature sleep patterns with an intense activation of the flight or fight emotion.


Night terrors are not a dream or typical nightmare. They occur in non-REM, slow-wave sleep. The panicked screaming, kicking, thrashing, and flailing is alarming in its intensity. Sleepwalking, another parasomnia disorder, may also occur in as many as one third of children with night terrors. While experiencing the night terror the child is extremely disoriented and may stare straight ahead, eyes wide open, with the dark centers (pupils) enlarged. There is profuse sweating, the heartbeat is rapid, the breathing fast, and the blood pressure is elevated. As the child is not fully awake, she is unable to see or recognize her parent or caretaker and cannot be easily awakened. The night terror may last from one to 15 minutes or more and is usually followed by a return to deep sleep. Afterwards the child may have no memory of the experience.

Night terrors appear to run in families, though there is no scientific evidence of genetic factors. They are a developmental process and not typically a result of mental or physical illness.


Childhood night terrors occur more frequently in boys. Children between the ages of three and five years of age are most likely to experience such nocturnal episodes. Such confusional arousals rarely persist beyond childhood, and they are significantly less frequent or cease entirely after age 12.

Causes and symptoms

Childhood night terrors appear to be a normal physiological process of the immature and developing nervous system. These confusional arousals can be triggered by stressful circumstances such as when a child is overly tired, when there is a loud noise or other unusual disruption, a change in the child's regular sleep-wake schedule, or even a full bladder. Night terrors occurring in adolescence and adult life may be more severe and are often linked with trauma and post-traumatic stress disorders.

Consult a pediatrician for night terrors if any of the following occur:


Diagnosis is based on observation of the following characteristic symptoms:


Parents should not attempt to awaken a child experiencing a night terror. Efforts to console may be futile, though holding the child firmly and speaking with soothing words may facilitate the return to deep sleep. The primary effort should be to protect the child from possible harm to herself and others and ease them back to sleep.

In some severe cases, a pediatrician may prescribe a benzodiazepine tranquilizer, such as diazepam, known to suppress the stage four level of deep sleep. Though tranquilizers may be used for short-term control of night terrors, the result is uncertain and not generally advised.

Hypnosis, biofeedback, and various relaxation techniques have been used with some success to reduce or eliminate occurrence of childhood night terrors. Calming music or bedtime stories can help lull a child into deep sleep. Maintaining a quiet home without sudden disruptive noise will minimize some of the external stimuli that may trigger night terrors.

Unusually heavy or spicy meals should be avoided before bedtime as indigestion might act as a trigger for night terror arousals.


Childhood night terrors are usually outgrown by the age of seven and rarely persist beyond adolescence.


Some pediatricians suggest that parents maintain a sleep diary and observe the child throughout several night terror episodes, noting the amount of time following sleep when the night terror begins. After the sleep-wake pattern is determined, a series of 15–20 minutes prior to the usual occurrence of the night terror and keep the child awake and out of bed for a full five minutes. This may help to break the disruptive sleep pattern that has resulted in the night terrors.

Children often experience night terrors during the toilet-training years. The night terror might be triggered by a full bladder. Assisting the child to the toilet prior to bedtime and even during the course of a night-terror might be beneficial in reducing reoccurrence.

Parental concerns


Benzodiazepine —One of a class of drugs that have a hypnotic and sedative action, used mainly as tranquilizers to control symptoms of anxiety. Diazepam (Valium), alprazolam (Xanax), and chlordiazepoxide (Librium) are all benzodiazepines.

Confusional arousal —A partial arousal state occurring during the fourth stage of deepest sleep. Childhood night terrors are a form of confusional arousal.

Parasomnia —A type of sleep disorder characterized by abnormal changes in behavior or body functions during sleep, specific stages of sleep, or the transition from sleeping to waking.

Rapid eye movement (REM) sleep —A phase of sleep during which the person's eyes move rapidly beneath the lids. It accounts for 20–25% of sleep time. Dreaming occurs during REM sleep.
