Pediatric Cohort Study

Narcolepsy is a rare disease that affects 0.05% of the general population. It is characterized by a dysregulation of the sleep wake regulation that leads to uncontrolled sleep episode during day and a disorganized sleep during night. These symptoms are due to a loss of hypocretin neurons in the brain leading to an inability to maintain wake properly. The physiopathology of this rare disease still needs investigations. Since we are a reference center for this disease, we propose to use patients files to better describe and document the sleep characteristics of these children, the cognitive performances, the effects of narcolepsy treatments on sleep architecture and the metabolic status of these children.
