Multiple sleep latency test (MSLT)

This test, performed in a sleep lab, objectively determines your degree of sleepiness. On the day following an overnight sleep study, you will be asked to take four or five naps over an eight to ten hour period. Each nap period lasts about twenty minutes. During these nap periods, you will be closely monitored, as you were during your sleep study. Bring a book, crossword puzzles, or anything else with which you can entertain yourself between naps.

Maintenance of wakefulness test (MWT)

This test measures your ability to stay awake. It consists of four nap opportunities, each lasting 40 minutes. During the nap period, you will be asked to try to stay awake. Most people without excessive sleepiness remain awake during these nap periods.
