A CAT scan taken yesterday did not indicate any major change in his condition - the bleeding has stopped, the bleeds have not worsened, but they have not reduced in size. My father seems to be gradually recovering his abilities to communicate and interact, though I fear that the aphasia that was a major result of his stroke ten years ago has returned. There are ways of dealing with and assessing this; ten years ago I used an instant camera to take photos of familiar things - my mother, our cat, McDonald's Golden Arches - and used them as flashcards to see what he could identify. (He got the cat right away - and then proceeded to identify every person in the photos by the cat's name.)
So what happens when these bruises on his brain begin to break up? I have no idea. For now, we will just have to continue to wait and see.
