While there is no known cure for narcolepsy, it is usually controllable with various treatments. However, the effects that narcolepsy has on a person's life can be quite devastating depending on the degree of narcoleptic symptoms and the effectiveness of the treatment.
Narcolepsy is not a fatal disease itself but may result in death if a sleep attack occurs when driving a car or operating heavy machinery. It also has a profound effect on the person's social and emotional life. The person may feel inhibited to participate in any social activities or functions because they do not know when an attack might occur.
Much research has been conducted on narcolepsy, yet there is no cause has been isolated. Perhaps further funding and research will increase the possibility of finding a cure.
