If the doctor used the words massive stroke, it was probably her way of letting you know that damage amassed is great. It isn't a medical word, but has taken on that connotation to help non medical people try to grasp the immensity of a situation. Let me start by saying that I am very sorry for this event. If the patient survives it, there will be slow, tedious progress, even if all goes well. The return to prestroke condition is not the usual occurrence. His ability to react to pain is not uncommon. The most basic part of the brain regulates breathing, pain sensation, and some chemistry for the heart to remain beating. Grunting when reposition is very often a natural reaction also. After some other test results are in, the doctor will have a clearer picture of the actual diagnosis and prognosis. Hopefully she will have good news for the spouse, family and friends. He is my prayers. God bless you for caring.
