Before I'd my PN onset, I'd suspected apnea, but not to a degree to be tested. Most of it was sinus related and meds controlled the worst of it.
When I'd had my onset, the neuro wanted to do tests for apnea and other sleep tests, but I'd refused. WHY? Because apnea and other issues disappeared for three years after my onset. Well, it's back now, and I will ask for apnea testing, I think....
The connections are kind of scary in that article...While not a big test, it does show connections that seem to be relevant.
It IS dense reading for sure, but if you take your time and FOCUS you'll get the solid parts of the gist of the thing.
Yeah, its' tech talk, but it also is in ENGLISH...ergo the 'connectors' we should at least get!

Good find again! - j
