Occasionally, when a person with a night terror is awakened, they will lash out at the one awakening them, which can be dangerous to that individual. Most people who experience this do not remember the incident the next day, although brief dream images or hallucinations may occur and be recalled. Sleepwalking is also common during night-terror bouts, as sleepwalking and night terrors are different manifestations of the same parasomnia. Both children and adults may display behaviour indicative of attempting to escape; some may thrash about or get out of bed and begin walking or running around aimlessly while inconsolable, increasing the risk of accidental injury. The risk of injury to others may be exacerbated by inadvertent provocation by nearby people, whose efforts to calm the individual may result in a physically violent response from the individual as they attempt to escape.During lab tests, subjects are known to have very high voltages of electroencephalography (EEG) delta activity, an increase in muscle tone, and a doubled or faster heart rate. Brain activities during a typical episode show theta and alpha activity when monitored with an EEG. Episodes can include tachycardia. Night terrors are also associated with intense autonomic discharge of tachypnea, flushing, diaphoresis, and mydriasis—that is, unconscious or involuntary rapid breathing, reddening of the skin, profuse sweating, and dilation of the pupils. Abrupt but calmer arousal from NREM sleep, short of a full night-terror episode, is also common. In children with night terrors, there is no increased occurrence of psychiatric diagnoses.
A polysomnography can be recommended if the child continues to have a lot of night terror episodes.Hypnosis could be efficient. Sleepers could become less sensitive to their sleep terrors.One technique is to wake up just before the sleep terrors begin. When they appear regularly, this method can prevent their appearance.Psychotherapy or counseling might be helpful in some cases. If all these methods are not enough, benzodiazepines (such as diazepam) or tricyclic antidepressants may be used; however, medication is only recommended in extreme cases. Widening the nasal airway by surgical removal of the adenoid was previously considered and demonstrated to be effective; nowadays, however, invasive treatments are generally avoided. Research
A small study of paroxetine found some benefit.Another small trial found benefit with L-5-hydroxytryptophan (L-5-HTP). See also
