There are only two types of narcolepsy, but each person with the disorder has a different experience. It can range from severe and debilitating to manageable. Both types of narcolepsy can change throughout the lifespan. There are also external factors that seem to affect the presentation of certain symptoms.

The two types of narcolepsy are Type 1 (previously termed Narcolepsy with Cataplexy) and Type 2 (previously termed Narcolepsy without Cataplexy).  It is possible for a person’s diagnosis to change from Type 2 to Type 1 as symptoms develop. Sometimes the person becomes aware of symptoms of cataplexy that were difficult to identify.  Both types of narcolepsy can be treated with medication.  They cannot be cured at this point in time.
