Does narcolepsy worsen over time?

Since each person's experience with narcolepsy is unique, it can get worse with time. Symptoms including excessive daytime drowsiness, cataplexy, and sleep paralysis can often worsen or occur more frequently as a person matures. Some narcoleptics, however, go through a plateau when their symptoms eventually level off. Medication such as Modalert 200 (modafinil) can be used to treat symptoms and keep them from getting worse.
