Multiple Sleep Latency Testing (MSLT)

The Multiple Sleep Latency Test (MSLT) measures the amount of time it takes you to fall asleep during a daytime nap period. We use this test to provide an objective measurement of sleepiness.

How is an MSLT Useful?

The Multiple Sleep Latency Test can be used for a variety of sleep disorders, including narcolepsy and excessive daytime sleepiness. It can also be used to assess the effectiveness of existing sleep disorder treatments.

How Does MSLT Work?

The Multiple Sleep Latency Test (MSLT) consists of a series of 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.

The test usually consists of several 20-minute nap opportunities, scheduled throughout the day. During this test, we will measure your brain waves, muscle activity and eye movement to assess your level of physical and mental tiredness.

The MSLT normally follows a nocturnal sleep study and in the morning the technician removes some of the wires from the sleep study.

What Can I Expect During My Test?

On the day of your test, you will be asked to refrain from stimulants such as coffee, tea, sodas or tobacco. Once the test begins, you will be asked to remain awake between the nap periods. The nap periods will occur every two hours until the test is completed.

Our friendly and knowledgeable staff will go out of their way to make you feel relaxed and we will even provide your meals during your stay.
