Yes, in fact your Brain can forget to make you breathe,
That is the problem I have.
About a year ago I was having all the normal problems of someone sleep deprived. (Had been having them for years, they just had been building though) And my wife sent me to the Doctor because I would stop breathing in my sleep a lot.
In the end here was the results.
Central Sleep Apnea, 42 events a hour. Blood ox would drop to the low 70% at the worst.
I went in for a CPAP Tiration, which I failed... and then was changed to a Bipap One which I did not do so hot on, and then I went in for a Bipap ASV one that did not cure me either. In the end my Dr decided that we would try a mix of a Bipap and supplementel oxygen.
I am currently using a Resmed VPAP auto 25 Bilevel. Set to 15 / 11. With 2 LPM of O2 added into the system. (The reason for the Auto 25 over the ASV machine is because I got the same results with either machine and the Auto 25 is about $2'200 and the ASV is about $5'000.)
Each Morning I check my machine and I am usully 1-2 on the AI (Apena events per hour) and AHI of 7-12 (Shallow Breathing).
Your best bet is to go into a sleep Dr and have a sleep study, My sleep Dr is a Nerougolist. And I would reccemend that you either go through one who is a Neurogolist or a Pulmoligst (I know my spelling is subpar)
I will tell you what my Dr has told me, Pure Central Sleep Apnea is a tricky thing to manage and really intresting adventure. (My translation, it sucks!) One caution, do not try to treat this one on your own. During my tiration they had to be real carefull because small adjustments to my preassures caused my Apnea's to go crazy. They had me stop breathing for a whole minuete once and the tech had to come wake me up. My AHI was up to 90+ at one time during my Cpap/Bipap Tiration.
Go to a good sleep lab, get a sleep study done, and make sure to get copy's of your tests results. When I first went in I felt awful but thought it would be mild sleep apnea. Imagine my surprise. I am normal weight, don't fit the criteria for someone with sleep apnea.. but then again I don't have OSA, I have the brain being stupid type.
Let me know if you have any questions, I have been fighting this one for almost a year now, I feel a lot better then I ever did. But I am not at the magic 0 AHI number that everyone wants. And nor do I think I ever can be.
