Evolution of the Treatment of Rare Hypersomnias in a Reference Center Certified Since 2005

Central hypersomnias are rare diseases that include narcolepsy and idiopathic hypersomnia. The Sleep and Vigilance Center at Hôtel-Dieu has been certified as a Rare Disease Reference Center (CRMR) for these conditions since 2005. Scientific advances and changes to the ICSD (International Classification of Sleep Disorders) since 2005 (diagnostic criteria and drugs brought to market) have greatly improved the care of patients with central hypersomnia. This retrospective and prospective study aims to evaluate how each advance translates into concrete terms in the care of patients followed at our center. Main objective : Determine whether new treatments are prescribed to replace treatments already on the market (reduction in prescriptions for treatments previously marketed) or whether they enable patients who have reached a therapeutic impasse to be treated (no reduction in prescriptions for treatments previously marketed).

Inclusion Criteria: 1. Patients who have had at least one consultation or examination at the Sleep and Vigilance Center at Hôtel-Dieu since January 1, 2005; 2. Patients diagnosed with narcolepsy (type 1 or type 2) or idiopathic hypersomnia; 3. Adult patients (aged 18 or over); 4. Patients who have not objected to the processing of their data. Exclusion Criteria: 1. Minors; 2. Patients who object to the processing of their data; 3. Patients under guardianship or conservatorship.
