Her problem wasnt that her brain was shrunk, it was that big chunks of it were missing for over ten years. The entire brain didnt shrink in the final days due to dehydration, parts of the brain died and the tissue rotted away and the space was filled up with spinal fluid as nature abhors a vacuum.
I never realized so many people had so much schooling in anatomy. I'm amazed that there are so many qualified to immediately dismiss any opinion, including the opinion of the person who opened her head and actually saw her brain, when they did not. Just so many know for a fact the brain shrinks in half with dehydration.
