Maintenance of Wakefulness Test
The maintenance of wakefulness test is given during the daytime. The MWT usually follows an all-night sleep study. The MWT consists of a series of 40-minute naps, during which the patient tries to stay awake. The test is given every two hours throughout the day, with each trial lasting about 40 minutes. During each nap, sensors and electrodes record data on body functions (EEG, heartbeat, breathing, etc.)
