Dear Mr Patra, Usually after an ischaemic stroke, the part of the brain that has been completely destroyed because of lack of blood supply does not recover its funcion. It is the surrounding areas of the brain which will need to take over the function of the affected part. This will take time and especially in an elderly gentleman like your father, it may not happen completely. Therefore it is possible that he will be left with some extent of permanent paralysis. Once he has come out successfully from the acute hospitalisation he will definitely improve, but the improvement will be gradual and most likely incomplete. Eventully, the doctors will attempt to remove his feeding tube and urinary catheter, ut when it may happen is difficult to predict. I gwould assume that the side of paralysis is Left sided arms and legs? This is because his left brain is affected and this controls the opposie side arm and leg function and the speech in right handed individuals. Hope this helps.
