Brief Summary:
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.
Detailed Description:
Hypersomnolence is a frequent and disabling symptom that has an impact on an individual's daytime functioning and particularly on driving, increasing the risk of traffic accidents related to sleepiness. Objective markers for assessing hypersomnolence are particularly important to overcome reporting bias since it is listed as a factor of temporary medical incompatibility to obtain or maintain a driving license in several countries, including France. According to the American Academy of Sleep Medicine (AASM), the MWT is the most relevant test for medico-legal assessments of fitness to drive.
Several experimental and epidemiological studies have shown that mean sleep latency at the MWT is a valid biomarker for assessing driving risk. However, there is currently no data on the test-retest reliability of the MWT from one day to the next. This is all the more important given the implications on the driving ability, and the variability associated with good participant compliance (good sleep hygiene the night before the test, absence of stimulation during the test). This study will use a factorial design to allow for stratified analyses with strong power (50 participants with Obstructive sleep apnea syndrome (OSAS), including 25 before/without treatment and 25 after/under treatment, and 25 participants with narcolepsy type 1 ,(after/under treatment) and 25 healthy volunteers. All participants will undergo an inclusion visit (V0) and two MWT (V1 and V2) separated by less than 28 days. All MWT will be twice blinded analyzed by a single expert to minimize variability of interpretation.
