Actually while the causative factors are the same in both stroke and heart attack--usually arteriosclerosis--a stroke deprives the brain of blood--not the heart. You can think of it as a heart attack in the brain if you like.

I have treated many stroke patients. A recent stroke patient I saw is 99 years old.

The question is not, Can they reason? nor, Can they talk? but, Can they suffer?
