Sleep disorder, or heterosomnia, is a complex behavior that usually occurs during the partial awakening period of slow wave sleep. This means that the child is in a deep sleep state, partially awake, but not fully awake. The 2 types of oversleeping disorders that commonly occur in children include sleep terrors and sleepwalking disorder. Sleep terrors, also known as night terrors, have a birth rate of about 1.5% to 2.9%, with slightly more males than females. It can occur at any time in children, but is more common between the ages of 5 and 7. It is rare after adolescence. Night terrors mostly occur within half an hour after falling asleep, and no later than 2 hours after falling asleep, when they are in the Ⅳ stage of non-eye fast moving sleep. At the time of onset, the EEG is a deep sleep waveform with no abnormal waves. The clinical manifestation of night terrors is that the child suddenly cries out, sits up, shrieks, looks straight or tightly closed, is restless, moves his hands and feet, or jumps out of bed with a horrible expression, but remains hazy, disoriented, and unresponsive to the surroundings; it may be accompanied by obvious autonomic excitement: pale face, rapid inspiration, dilated pupils, and rapid sweating pulse. If the child is called, it is usually difficult to wake him/her up, often ignoring him/her, but still showing panic, crying or shouting, nervously grasping anyone, seemingly continuing to suffer some kind of intense pain, while ignoring the reassurance, hugs and anxiety of the mother and father, etc. This situation can often last for some time, and then fall asleep on its own. Some children may have nocturnal episodes in which they get up and walk around and do simple mechanical movements, such as opening and drawing, which they cannot recall after waking up. The number of attacks varies, from several attacks a night to one attack a few days or ten days. The cause of night terrors: mainly anxiety, frightened and other psychological factors. For example, serious illness or death of a family member, leaving parents for the first time to enter an unfamiliar environment, anxiety and terror caused by trauma and unexpected events. In addition, listening to scary and stressful stories and watching scary and stressful movies before bedtime can lead to night terrors. Excessive fatigue, physical discomfort, and physical weakness are all triggering factors. Fifty percent have a family history. Differentiation: Temporal lobe epilepsy: 1. In addition to night terrors and sleepwalking, there are other types of seizures, such as disoriented seizures and grand mal seizures. 2. The seizure process cannot be recalled. 3. EEG temporal lobe with epileptic waves. What should I do when I have a night terrors seizure? Parents should remain calm and not overly nervous about night terrors in children. Parents should not try to wake the child up and should not hug the child who is having a night terror. At this time, sound is more helpful than contact. Parents can speak gently to the child or sing a few of the child’s favorite songs to help calm him or her down. After a seizure, it is important to assist the affected child to get back to sleep, cover him with a blanket, etc. You should make sure that the child does not hurt himself, try to keep the child in bed, and keep him safe. Attention should also be paid to preventing accidents that may occur during night terrors with nocturnal episodes. Parents also do not need to discuss this matter specifically with their child, lest it add to his psychological burden. Treatment: Night terrors in children have a good prognosis and generally resolve on their own as they grow older. Generally, no medication is needed, but those with recurrent attacks and a high number of episodes can take sedatives such as Valium under the guidance of a physician. Children with frequent night terrors often reflect the existence of a persistent state of anxiety in the child, so further understanding of the child’s psychological state is needed for psychological guidance. The best way to prevent night terrors is to have a good living environment, not to watch scary TV, to take care of rest, to arrange the right amount of activities for the child, and to maintain a stable and adequate sleep schedule. Supportive psychotherapy can be used to eliminate various triggers, and attention should be paid to cultivating the brave spirit of children.
