There isn't a lot published about UARS, it was recognized/discovered in the mid '90s. Just my opinion (experts please pitch in). UARS seems similar to central apnea in which the brain decides not to breathe. Perhaps the brain is more sensitive to and detects difficulty breathing before an apnea or hypopnea has taken place (remember an apnea is not breathing for 10 seconds). This would occur during or in the transition to slow (stage 3&4)wave sleep when the muscles begin to go into deeper relaxation.

I don't consider it a lesser disease (that's because I have it). The outcome is you awaken many times a night, but your oxygen desat might be ok because you don't stop breathing as much (remember the more sensitive brain). But mostly you don't attain much deep sleep or REM. "I" theorize the result is physical fatigue and well being suffer because of the loss of slow wave sleep and mentally because of the loss of REM. "I" theorize that many who have apnea well treated with PAP but still suffer may have untreated UARS. UARS does show up on standard tests. In your results they may be referred to as respiratory arousals or RERA or unexplained. Hope this helps and I haven't strayed too far in my attempted explanation. Good Luck.
