Negative for apnea

Post by Valhallan » Tue Jun 12, 2018 3:05 pm

Good afternoon everyone,

Finally got the results of my sleep study. It came back negative for sleep apnea but 0% for deep sleep and REM sleep. The doctor is requesting an MSLT to test for other things outside of apnea (like narcolepsy). Will the MSLT retest for apnea? As some of you know, I had a rough night where I vomited several times during the study and ended up needing to get prednizone(sp?) for an allergic reaction to something. My symptoms and what others have observed seems to better correspond with apnea, but I wasn't sure if this is part of the MSLT process the night (I sleep overnight at the clinic). Thanks!

Given the fact that you became so ill at the sleep study...and you didn't get any REM or deep sleep where often OSA is worse...I am not so sure that I wouldn't be pushing for a repeat sleep study for the apnea.

MSLT...mainly a test for narcolepsy and excessive sleepiness of unknown origins

+1 on wanting a redo on the diagnostic study.

Definitely agree on the redo for sleep apnea test. The lack of deep sleep and REM sleep is an issue, and they could not test you in the worst case scenario. It sounds like it was inconclusive, not negative.

Who would have thought it would be this challenging to sleep and breathe at the same time?

What are the arousal numbers? 0% N3 and REM sleep is very poor quality sleep if the result is accurate. MSLT includes both night (sleep) and day tests.

Hey everyone, an update.

Per your advice I confirmed my MSLT had a PSG before it. Tested positive for apnea this time so they skipped the MSLT portion. Thanks everyone for your advice!

It sounds like you had a second overnight test, but you did not state that explicitly.

Just because you tested positive for Sleep Apnea doesn't mean you don't also have Narcolepsy or some other sleep disorder, so I'm not sure why that test was cancelled.

Common to end the PSG with the confirmation of OSA and not do the MSLT part for narcolepsy until the OSA is treated optimally and see if the potential narcolepsy symptoms persist or not.
It wouldn't be an accurate test for narcolepsy with untreated OSA muddying up the waters and potentially causing false positives in the narcolepsy part of the test. So putting off the narcolepsy part of the test is done to give a chance for the OSA to be treated and potentially simply take care of the symptoms. To continue without fixing the OSA stuff first means we don't know if a person's potentially positive narcolepsy findings were because of the OSA or because of the narcolepsy. Waste of time and money to do a study that wouldn't necessarily be accurate if positive. They would still have to come back and retest once on cpap if the unwanted symptoms persist.
There's a good chance that they won't once the known problem is taken care of.
