Question:
How is a Multiple Sleep Latency Test (MSLT) defined in terms of coding procedure?
Answer:
Multiple sleep latency test (MSLT). Sometimes referred to as nap testing, MSLT is performed as a series of recordings to monitor the patient’s sleep patterns in order to evaluate excessive daytime sleepiness and narcolepsy (sudden and uncontrollable onsets of sleep). This test measures how long it takes to fall asleep during the course of a day. A video camera records movements during sleep. Eye movements, brain electrical activity, and muscle-tone changes are recorded during 15- to 20-minute naps, spaced about 2 hours apart.
