A Study to Collect Information of People With Narcolepsy in Spain

This study aims to review information of people with a sleep condition called narcolepsy. Narcolepsy is a condition that causes extreme sleepiness during the day including falling asleep suddenly. Study doctors will review the medical records of the participants from sleep clinics in Spain. They will do this from 1 year before the participant was diagnosed with narcolepsy up to the start of this study. Participants will visit the sleep clinic once. During this visit, the study doctors will carry out a short medical exam. Participants will also complete a few questionnaires during this visit. If participants cannot visit the clinic for any reason, the clinic staff will arrange a phone call instead.
