Sleep Testing Center in Westmoreland County, PA

Multiple Sleep Latency Test (MSLT) & Maintenance of Wakefulness Test (MWT)

Different types of sleep tests are used to diagnose different types of sleep disorders. Two of the most common types of sleep tests used are Multiple Sleep Latency Tests (MSLT) and Maintenance of Wakefulness Tests (MWT), which are done in the daytime. The MSLT is a test that measures how quickly you fall asleep during a series of naps, while the MWT measures how difficult it is to stay awake during a series of tests. 

Dr. Jain at Westmoreland Sleep Medicine in Greensburg, PA specializes in administering both MSLT and MWT tests for patients suffering from sleep disorders such as narcolepsy or obstructive sleep apnea (OSA). Our facility is designed to be a comfortable and welcoming environment for all of our patients, and Dr. Jain will work with you personally to ensure that your test is as comfortable and stress-free as possible. 

If you're interested in getting a MSLT or MWT, please don't hesitate to schedule a consultation with Dr. Jain at Westmoreland Sleep Medicine. We'll be more than happy to answer any questions you may have about the process.

MSLT & MWT: How They Work

The Multiple Sleep Latency Test (MSLT) consists of a series of 4-5 short nap periods during which your  brain waves are monitored to determine if you fall asleep, and if you do  fall asleep, do you enter into REM sleep. An MSLT sleep test normally follows a  nocturnal sleep study. The first nap period will start at approximately 7:00 AM with the rest of the naps occurring every two hours until the  testing has been completed. You will be asked to remain awake between  the nap periods. The staff at Westmoreland Sleep Medicine will go out of  their way to make you feel relaxed and comfortable during your stay.

The Maintenance of Wakefulness Test (MWT) is a test that helps determine a person's level of alertness. It  is often used to determine if a patient's treatment for sleepiness is effective. It is also used to determine a commercial driver’s ability to stay awake in the daytime to renew their CDL. Testing starts at 8:00 a.m. and consists of four 40-minute trials that  are conducted every two hours until the testing has been completed. You  will be sitting in a darkened room and you are encouraged to stay awake during the trials and between each study.

Frequently Asked Questions

How should I prepare for these tests?

Both MSLT and MWT tests require you to be well-rested prior to coming in for the test. It's important that you have at least 8 hours of sleep before your test and refrain from drinking alcohol or caffeine within 12 hours of the test. Additionally, be sure to wear comfortable clothing that will not restrict your ability to move while you're in the test.

How long will it take to see my results?

After the MSLT or MWT is completed, we will typically have your results within one to two weeks.
