A stroke big or small is where there is a permanent loss.
AHI -apnea-hypopnea index is the amount of time you spend with low or no breathing during a sleep study - obviously it is bad not to breathe because it reduces the oxygen supply everywhere - including the brain.
Sleep apnoea is commonly associated with hypertension and/or obesity.
Intermittent narrowing of the upper airways because of fat in the airways combined with other mechanical factors causes it - even so, non-obese people can also get it.
The main treatment - a device sold by RESMED - generates a continuous positive pressure in the airways when you are asleep.
It was invented by a friend of mine from the Royal Prince Alfred Hospital - Sydney University - Dr Colin Sullivan.
Blood pressure measurement - when, where, who - is a big problem in the diagnosis of high blood pressure. This is why the gold standard is a 24-hour ambulatory measurement (see above). The ABPM is the blood pressure equivalent of a Holter monitor which checks your ECG for 24 hours.
In a way, it is also political. Successive Australian governments have decreased funding for medical research and training. Now they complain that we aren't making and distributing vaccine because of 'supply problems' - not at all surprising when you remove funding from all the 'suppliers'.
Trump's contempt for research - "I could have been a scientist - it's easy - I know all this stuff - the Doctors are amazed" - to paraphrase - was a massive problem.
Progress was made because the residual infrastructure worked around him.
Most of this I knew, although not the details. Although a TIA is not a stroke, and this was exp[lained to me, the docs were concerned that it could be the forerunner of a stroke. The search for the cause was not all that different than the search for the cause of a stroke. And as I get it, a high AHI can trigger a TIA and it can trigger a stroke. Maybe trigger is not the exact word, you are more inclined toward exact phrasing than I am, but I stand by my belief that discovering and treating my apnea was perhaps life-saving. And I will repeat that I really liked that doctor. Some docs are stingy with info, maybe because they fear the patient is not able to understand or not up for hearing it. She spoke in a way that did not need deciphering. My older daughter has had medical issues and we share a view on this. As she phrased it "You want me to trust you? Tell it straight." Anyway, the doc discovered the apnea, I am very grateful.
I have an ASV, made by Phillips. Seems to work well, since the AHI is around 2. There is a story around that also, but enough, at least for this thread. Send me an email if you want more details. kenbecky@gmail.com
As to Trump and his bragging, what can I say that hasn't been said?
