Sleepwalking It is an automatic movement during sleep in which the patient rises, gets up and walks, or does other more complex activities, but maintains a simple responsiveness to the environment. The patient’s eyes are usually open, may mumble repetitively, sometimes trips over obstacles or stairs, and each episode lasts about a few minutes with no memory of it afterwards. Although called sleepwalking, the episodes are all in stage III or IV of the less dreamy phase, and there is no recollection of a dream upon awakening, and an immediate EEG is essentially consistent with that of wakefulness unlike that of sleep. It is more common in children, and can be self-cured in adults. Adult sleepwalkers are often associated with psychiatric disorders such as schizophrenia or neurosis. Automatisms in temporal lobe epilepsy usually occur only during the daytime, and sleepwalking rarely occurs. Valium and other can can inhibit stage III and IV sleep, and those with frequent episodes can take it before bedtime. Patients should sleep downstairs, and do not put dangerous objects in the room to prevent accidents. Nightmare, i.e. nightmare or horror dream, occurs in the rapid eye movement period, which is a state of fear and agitation triggered by strong dreams, and is relieved quickly and can recall the experience in the dream. It can occur in children or adults, and it is easy to occur in people with mental disorder or those who are mentally stimulated, and it is more common after overwork or drinking alcohol, and those who have nightmares for a long time need to undergo psychiatric treatment. Night terrors are characterized by episodes of commotion and shouting during sleep, with alarming screams like being continuously whipped. It is accompanied by vegetative symptoms such as accelerated heartbeat, respiration and sweating, as well as strong fear, anxiety and a sense of suffocation, and occasionally there may be hallucinations. Each attack lasts 1-2 minutes, and there is no memory of the attack after waking up. It is more common in children, and can also be seen together with nightmares, and is mostly self-resolved in adults. Adult patients are often accompanied by psychiatric disorders such as anxiety disorders and chronic alcoholism, and the episodes mostly occur in the first round of stage IV of sleep, with the electroencephalogram suddenly showing an awakening state. Taking 2-5mg of Valium before bedtime can sometimes play a preventive role.
