Hi Welcome to Healthcare Magic Forum Narcolepsy is a disorder of the nervous system, which makes a person sleepy. Sleepymoslt during day, and sleepless at nite, the patients may fall in to deep sleep at odd times, and inappropriately. This hampers work/study /routine life. ALso there is sudden episodes of weakness , asif losing control on the muscles. Some expericnce halluciations as well. Walking or doing things while you are asleep and then ont remmbering them is also a symptom. Not lifethreatning , but definitely stressful for patient and family. You can see a neurologist for a confirm diagnosis. Homeopathic medications can be helpful in this condition. Takecare.
