The Multiple Sleep Latency Test (MSLT) is indicated in the assessment of excessive daytime sleepiness. It is performed following a supervised overnight polysomnogram. The presence of 2 or more sleep-onset REMs (SOREMs) in an MSLT following a normal polysomnographic study the night before supports a diagnosis of narcolepsy.
