So clearly these studies indicate that in these POTS patients, absolute blood pressure was maintained in POTS orthostatically (and in some perhaps is increased) while cerebral autoregulation - the system designed to protect the brain from beat-by-beat fluctuations in blood pressure and maintain regular blood flow to the brain is abnormal in POTS.

the consequences seem to be dizziness and mental clouding.

Interesting that in the 2009 study there was a difference between the POTS and control groups in CBFV but in the 2012 study it said there wasn't a difference in the CBFV between the CFS/POTS and control groups.

Since I'm upright while reading these maybe I'm missing something. LOL

Thanks for posting these.

" Individuals with CFS/POTS should be aware that orthostatic stress may impair their neurocognitive abilities."

I am so glad they did a study to make me aware of this(stated very sarcastically!).

WHEN are the researchers going to do the REAL research into POTS????? We need research into the whys and then that will help on the hows regarding treatment.

although i understand what you mean sue, i'm very glad that it's on paper now. a few years ago when i had my neurocognitive tests done it resulted in what should suite an 80 year old person where i was just 40. as the man in charge (prof) had nu clue why this was the outcome (and alzheimers was ruled out) he suggested a psychiatrist might be able to "fix" this. fortunately my ans doctor (though not convinced at that time it could be caused by my dysautonomia) didn't think seeing a psychiatrist would help me.

of course we all here on dinet knew what was going on :)
