How many persons go insane while recovering from a stroke?

A very serious question for your doctor. Think about it. If you have vast areas of dead brain like me, you need to find new areas and relocate lots of functionality. If you are smart enough your executive control does not allow itself to be taken over by mere motor control activities. I wonder if I am smart enough to prevent that? Explode your doctors brain with that brain teaser, and don't allow deflection and a non-answer to suffice.
