MSLT
MSLT or Multiple Sleep Latency Test is a sleep disorder diagnostic tool. It measures the speed at which a person falls asleep in a quiet environment during the day. Also known as a daytime nap study, the MSLT is the standard tool used to diagnose Narcolepsy and Idiopathic Hypersomnia.
Procedure[edit | edit source]
The MSLT uses a series of five scheduled naps separated by two-hour breaks. During each nap trial, the patient is in a quiet, dark room and is instructed to try to fall asleep. The time it takes for the patient to fall asleep is measured from the start of each nap opportunity. If the patient does not fall asleep within 20 minutes, the nap trial is ended.
Interpretation[edit | edit source]
The MSLT measures the speed at which a person falls asleep. This is known as sleep latency. In normal sleepers, sleep latency is typically 10-20 minutes. In people with sleep disorders, sleep latency can be significantly shorter. A mean sleep latency of less than 5 minutes is considered very suggestive of Narcolepsy.
Limitations[edit | edit source]
The MSLT has several limitations. It may not be accurate in people who have recently changed their sleep schedule or who have consumed alcohol or caffeine. It also may not be accurate in people who are taking certain medications.
