I had a home study that showed both central and obstructive sleep apnea events, 55% of apneas were central. Followed up several days ago with an in-lab test which was a nightmare (no pun intended). I have an anxiety disorder and my initial complaint (besides years of insomnia and waking up exhausted) was being awakened by severe adrenaline rushes, not just when falling asleep but all night. On the home test I could see these correlated with apnea episodes. No results on the in-lab test yet, but I am imagining all sorts of things from a brainstem tumor to a neuromuscular disease. Can anyone share their experiences with CSA? Anyone misdiagnosed with it on a home test? I am a female, 57 y.o., BMI 27, and have cervical spine disc disease.
