Via this, one can actually date CF's cognitive decline to after 2013/1.
This was important to me, as I've contemplated ECT for over a decade. CF had undergone ECT for 3+ years at this point, but evidently the microinfarcts from obesity & diet were the major impact.
Wish someone who understood vascular physiology, and who might have recommended a very low fat/Pritikin/Ornish/McDougall/Esselstyn program, had found her a few weeks ago.
