Major Depression, Sleep Inertia
Conditions
Keywords
psychomotor vigilance task
Brief summary
The study population comprises three groups of 30 analyzable participants: Patients with sleep inertia and Major Depressive Disorder, patients with Major Depressive Disorder but without sleep inertia, and controls without mood disorders or sleep inertia. Controls will be patients referred to the Sleep Disorders and Acupuncture Unit for polysomnography as part of the screening process for a sleep disorder. Only controls presenting an apnea-hypopnea index \< 15/h, a periodic leg movements index during sleep \< 15/h and a total sleep time ≥ 6 hours on the video-polysomnography will be analyzed.
Interventions
Five PVT tests (before sleep at 7pm, 7am, 7:30am, 8am and 11am). The PVT is a 10-minute test designed to assess the vigilance and sustained attention by measuring reaction times (RT) to visual stimuli. During the test, participants are required to monitor the computer screen and press the response button as soon as a millisecond counter appears which will stop the counter and display the RT in milliseconds. The stimuli are randomly presented.
Performed overnight as part of routine care (11 p.m. to 7 a.m.).
Actimeter and sleep diary to assess the sleep-wake patterns of the participants in their natural environments over a two-week period.
