Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with sleep inertia and major depression

Psychomotor vigilance task

Intervention Type OTHER

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.

Video-polysomnography

Intervention Type OTHER

Performed overnight as part of routine care (11 p.m. to 7 a.m.).

Sleep and activity monitoring

Intervention Type OTHER

Actimeter and sleep diary to assess the sleep-wake patterns of the participants in their natural environments over a two-week period.

Patients with major depression without sleep inertia
