abbr. multiple sleep latency test
Multiple sleep latency test. A series of measurements of the interval from "lights out" to sleep onset that is utilized in the assessment of excessive daytime sleepiness. Subjects are allowed a fixed number of opportunities to fall asleep during their customary awake period. Long latencies are helpful in distinguishing physical tiredness or fatigue from true sleepiness.
Multiple Sleep Latency Test. The MSLT is the primary test for the diagnosis of narcolepsy. This test assesses two major components of narcolepsy: hypersomnolence and sleep onset REM periods (SOREMPs), which occur in narcolepsy but are otherwise uncommon. The mean sleep latency, or time to sleep onset, provides evidence for hypersomnolence. Using an EEG to record sleep onset during normal waking hours, it consists of four or five 20-minute nap opportunities at two-hour intervals. Normally, sleep latency is greater than 10 minutes and REM sleep does not occur. Patients with narcolepsy typically fall asleep in 5 minutes or less and will display SOREMPs during at least two of the five daytime nap periods.
Movement li li b Multiple Sleep Latency Test
the acronym for multiple sleep latency test; a test used to study and document excessive daytime sleepiness by way of a series of naps at two-hour intervals.
multiple sleep latency test. a common sleep test given at sleep labs in the diagnosis of sleep disorders. The multiple sleep latency test records brain waves (via EEG), heart rate (via EKG), muscle activity and eye movements. Often given as a series of "nap tests".
Multiple Sleep Latency Test. This is a day long test where a patient is given periodic opportunities to snooze while wired up to sleep monitors, such as EEG, EKG, pulse oximeter, and more. It is used to measure daytime sleepiness over the course of a day, usually the course of a standard workday. Like a normal sleep study, it is completely noninvasive.
Multiple sleep latency test. Test that assesses the severity of sleepiness by measuring the speed of falling asleep.
Multiple Sleep Latency Test. Test of how long it takes to fall asleep. Usually repeacted 4 or 5 times in one day. Abnormally short time before you fall sleep is seen is sleep deprivation, severe sleep apnoea and narcolepsy.
Multiple Sleep Latency Test. The standard test used to quantify the overall daytime sleep tendency by measuring the speed of falling asleep (sleep latency) usually in 5 tests carried out at two-hour intervals. This test also helps in the diagnosis of narcolepsy. Patients with narcolepsy often go directly from wakefulness to REM, which can be evaluated with the MSLT.
Multiple Sleep Latency Test. a series of multiple (usually five) naps the day after a sleep study. The average (mean) time it takes to fall asleep is measured.
Multiple Sleep Latency Test. Test that consists of a series of short naps during the daytime, done in the sleep lab, to measure daytime sleepiness and how fast you fall asleep; Usually given to assist in diagnosing or ruling out the possibility of Narcolepsy
