MSLT

The MSLT (multiple sleep latency test) is a test for patients with excessive daytime sleepiness and measures how quickly you fall asleep in a quiet environment during the day. This test is often used to help diagnose narcolepsy and idiopathic hypersomnia. This test takes a full day and consists of 5 scheduled naps separated by 2 hour breaks. You will be sleeping in a dark and quiet environment and the sleep technician will wake you after 15 minutes of sleeping. They will also be measuring how long it takes for you to fall asleep. If you do not fall asleep within 20 minutes, the nap trial will end.
