That's fine, Worriedsis. I just wanted to be sure you knew there was no expert here but I really hope others here will have some thoughts for you once they've had a chance to look in.
FYI, my younger son (he's 27 now) has sleep apnea and it crept up on us, getting worse over time, and I don't think any of us realized how much this had been impacting his life in so many ways. Once that got treated, once he found the right pressure level, humidity and mask.... his world and his life have dramatically changed for the better.
Even if it doesn't completely make a difference for your family member, it could help clarify what else may be going on if that, at least, is being treated.
