Maintenance of Wakefulness Test
In order to determine how well you are responding to a sleep disorder treatment or to see how alert you are during the day, a maintenance of wakefulness test (MWT) can be performed. Sleep medicine specialists at Jefferson are highly skilled in conducting this test and were involved in the standardization of this test.
What Does a Maintenance of Wakefulness Test Involve?
A maintenance of wakefulness test isolates you from outside factors that can influence your ability to fall asleep, such as temperature and noise. The MWT consists of four nap opportunities with breaks lasting for two hours in between them. Sometimes you will also do an overnight sleep study the night before the MWT.
During each nap opportunity, you will sit quietly in bed and simply try to stay awake for as long as you can. Our specialists will be charting your wake/sleep times and looking over the data from the test to assess your level of daytime sleepiness.
