Patients with narcolepsy mostly present with irresistible daytime sleepiness and sleepiness unrelated to nighttime sleep, which in turn affects school, work and daily life. Patients with narcolepsy exhibit symptoms of excessive daytime sleepiness or prolonged transitions to full wakefulness during sleep episodes or wakefulness, and this sleep disorder is diagnosed only when it occurs almost daily for at least a month or repeatedly for a shorter period of time. In addition, if narcolepsy is not controlled, it continues to develop as slurred speech, stuttering, drooping eyelids, weak fingers that cannot hold things, mental depression, etc. In severe cases, the head and body may become paralyzed in the waking state without losing consciousness and collapse suddenly. Other patients show that they cannot move their body or have some horrible hypnagogic hallucinations when they go to sleep or when they want to wake up. Due to the poor mental state, narcolepsy patients then fall into significant pain and gradually alienate themselves from people, and in the long run, the vicious circle, the symptoms further aggravate, the memory of recent events decreases, thinking ability decreases, and the quality of life is significantly reduced. In summary, narcolepsy has a great negative impact in the long term. Usually we should pay attention to avoid overwork, stay up late, maintain a healthy state of mind and form good habits to reduce narcolepsy.
