Narcolepsy is a psychosomatic disorder that manifests mainly as excessive daytime sleep or prolonged transition time to a fully awake state when awake, a symptom not due to sleep deprivation, alcohol, drugs, or disease. The cause is unclear and is mainly related to psychological factors. First, patients with narcolepsy do not have organic factors that can cause this condition, such as neurological or other medical disorders, psychoactive substance use disorders, or the use of certain medications. Secondly, people with long-standing narcolepsy are sleepy and sleepy regardless of the occasion, and experience varying degrees of irresistible sleepiness, which can cause significant pain or a decline in occupational, social, and other social functions and quality of life, and if the episodes recur periodically, they can seriously disturb daily life. Further development of narcolepsy may result in changes in cognitive function such as memory loss, decreased thinking ability, and decreased ability to learn new things. If narcolepsy is not controlled, it can lead to sudden sleep onset, sleep hallucinations, excessive dreaming, mood changes, sleep paralysis and other serious symptoms. Therefore, maintaining a healthy lifestyle and interpersonal communication to avoid narcolepsy is an important element. It is often believed that active and effective physical exercise, a healthy attitude toward life, good sleep habits, and participation in sunny group activities can be effective in preventing narcolepsy.
