Can a sleep apnea test be done during the day?
Polysomnography may be done at a sleep disorders unit within a hospital or at a sleep center. While it’s typically performed at night, polysomnography is occasionally done during the day to accommodate shift workers who habitually sleep during the day.
What does a daytime sleep study show?
The MSLT tests for excessive daytime sleepiness works by measuring how quickly you fall 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.
How long are MSLT naps?
A positive MSLT is obtained when the patient falls asleep with a mean sleep latency below 8 minutes in the naps, and had at least no more than 1 nap (for idiopathic hypersomnia) or 2 naps (for narcolepsy diagnosis) where REM sleep was reached.
How reliable is MSLT?
Prior work with the MSLT has shown that MSLT retest reliability is highly dependent on the population under study. In healthy subjects, the MSL has retest reliability as high as 0.97 over 4-14 months.
How often is sleep apnea misdiagnosed?
More than 70\% of people with sleep apnea experience symptoms of depression, according to a new study published in the Journal of Clinical Sleep Medicine.
How long do MSLT results take?
It will take about two weeks to get the results of your MSLT. During this time, members of the sleep team will examine the results of your MSLT. A sleep technologist will review the data, note when you fell asleep during each nap, and look at your sleep stages and determine whether you entered REM sleep.
What can Mslt diagnose?
The Multiple Sleep Latency Test (MSLT) checks for excessive daytime sleepiness by measuring how quickly you fall asleep in a quiet environment during the day. Also known as a daytime nap study, the MSLT is used to diagnose narcolepsy and idiopathic hypersomnia.
Can you be falsely diagnosed with sleep apnea?
Con: They aren’t as detailed. A home test only measures breathing, not actual sleep, so results can be inconclusive or falsely negative. Patients with OSA often breathe through their mouths, which may lead to inaccurate signals. Although rare, a self-administered device may become loose on the finger at night, too.
