Have mini strokes been ruled out?
I never heard of wet brain. How interesting.
Somebody wrote here that at a certain point and alkie's brain turns to mush. I can tell you when my XAH's did, it was in early spring 2009. It was like his brain/personality collapsed and he just gave over to classic alkie behavior. Every once in a while, he'd rally but after May 2009, it was pretty much hopeless. I asked the kids once when they noticed a difference in him, 'when it became really bad'; they all mentioned Feb or Mar 2009. It was that distinct.
