1, sleepiness is an excessive daytime sleep or sleep attack. These sleep stages often occur at inappropriate times, such as when talking, eating or driving. Although sleep can occur at any time, it most often occurs during periods of inactivity or monotonous and repetitive activities.
2. Too much sleepiness during the day: This symptom always exists and is usually the most obvious. Cataplexy: Cataplexy refers to the sudden or temporary disappearance of muscle mass, which causes paralysis of the head or body without losing consciousness. It can last for a few seconds or minutes.
3. Mild symptoms are vague language or stuttering, drooping eyelids or inability to hold things with your fingers. Severe cataplexy can cause knees to bend and make people collapse. Laughter, excitement or anger are typical causes of cataplexy. The sudden relaxation of muscle quality may be the result of the brain suddenly entering REM sleep. Less than half of patients with narcolepsy have cataplexy.
4. Sleepiness usually occurs at the age of 15-30 at first, but some people have drowsiness earlier or later. Once drowsiness occurs, it will accompany you for life.
5. Men and women are equally affected. The first symptom of drowsiness is usually feeling very sleepy during the day. However, it may take several years to confirm that the patient does have this disease, because there are many other reasons that can cause sleepiness during the day.
6. Too much sleep or sleep attacks during the day. Sleep attacks can't be explained by lack of sleep time. The transition time to fully awake when awake is prolonged, and this sleep disorder occurs every day.
7. Persistent 1 month or repeated sleep attacks, causing obvious distress or affecting work or family life. Excluding daytime sleepiness and narcolepsy caused by various organic diseases, the onset of sleepiness is mostly related to psychological factors.
