What this Trial Is About
The main purpose of this study is to find out how many people in Spain have been diagnosed with narcolepsy type 1 and type 2, and how many new participants are diagnosed each year. Narcolepsy is a rare sleep disorder that causes excessive daytime sleepiness. The researchers will look at medical records from hospitals across Spain to count participants with these conditions and understand patterns in diagnosis over time.
