Test-retest Reliability of the Maintenance of Wakefulness Test in Participants With Hypersomnolence

This study will provide the first measurement of the test-retest reliability of the Maintenance of Wakefulness Test (MWT) with a prospective multicenter design. A high level of reliability will reinforce the place of the MWT as an essential tool to respond to the medical and legal worldwide issue of the driving risk related to hypersomnolence. This would legitimize its place as a medico-legal examination in France and promote its diffusion in other countries. A low level of reliability will call into question the place of the MWT in the management of participants with hypersomnolence. Bordeaux University Hospital is the sponsor of this research. This research will be conducted with the support of Société Française de Recherche en Médecine du Sommeil.
