Daytime Sleep Studies

In addition to nighttime studies, some patients require daytime testing to evaluate excessive daytime sleepiness or sleep disorders such Narcolepsy. Daytime studies are performed after previous sleep study night. We perform two different daytime tests: the Multiple Sleep Latency Test (MSLT) and the Maintenance of Wakefulness Test (MWT). During each of these studies, testing is performed for a brief periods during the day. The procedures for the MSLT and MWT will be reviewed for you in advance for your appointment.

The daytime MSLT and MWT are performed according to standardized protocols developed by the American Academy of Sleep Medicine (AASM). The MSLT is always performed following a previous sleep study night, but the MWT, in certain cases, may not require this previous sleep study night.
