Multiple sleep latency test
Multiple Sleep Latency Test (MSLT) is a standardized diagnostic test used to measure the time it takes a person to fall asleep during the day. The test is used to diagnose excessive daytime sleepiness (EDS) and evaluate the presence of sleep disorders such as narcolepsy, idiopathic hypersomnia, and sleep apnea.
How is MSLT performed?
The MSLT consists of four to five 20-minute nap opportunities taken at two-hour intervals throughout the day. During each nap opportunity, the patient lies down in a quiet and dark room and is instructed to try to fall asleep. The time it takes for the patient to fall asleep, known as the sleep latency, is recorded.
A normal sleep latency is typically less than 15 minutes. A prolonged sleep latency of more than 20 minutes may indicate the absence of excessive daytime sleepiness. On the other hand, a sleep latency of five minutes or less may indicate the presence of narcolepsy or idiopathic hypersomnia.
Where is it performed?
The MSLT is usually performed in a sleep laboratory, and the results are used in conjunction with other diagnostic tests, such as a polysomnogram, to diagnose and treat sleep disorders.
