Maintenance of Wakefulness Test
From W8MD weight loss and sleep centers
The Maintenance of Wakefulness Test (MWT) is a test that measures a person's ability to stay awake and alert during the day. This test may be used to evaluate a person's ability to perform tasks that require sustained attention, like driving or operating heavy machinery. During the MWT, a person is asked to sit quietly in a dimly lit room for 20-40 minutes and to try to stay awake. The test is monitored by a healthcare professional to ensure safety and accuracy.
