Stroke info

Patient: Hello my grandfather of 89 years recently had a stroke. After a ct scan the doctors said he has bleeding in the right side of the brain as well as the back of the brain. He seems to be regaining his motor skills in the hospital but still struggles with recognizing people as well as the areas he is in and his surroundings. Since he is too old for surgery what can be done? Will he ever be “back to normal”? And how long will his lifespan be? Please answer this question. I’m looking for answers as it is a dear loved one. Any information you offer will be of great aid. Thank you
