my father-in-law (age 87) had a stroke six months back. He had to undergo an operation as there was clot and bleeding in the brain. Now he responds to sound but not able to speak or express himself. He is bedridden, but able to move his hands and legs. We are trying to stimulate him with music, tv and talk. He opens his eyes when we call him but more than that he is not responding much. He is under medication for diabetic, B P, convulsion . We are giving him good nursing care and physiotherapy. What more to be done as a part of rehabilitation?
