Hello there.  I can understand your concern.  What medications is he currently on? You have to understand that this is how life of most patients become after suffering a stroke if not taken adequate care. He probably always had high blood pressure which was not treated. Consult a neurologist in person for further evaluation and management. Best regards. Dr. Anil kumar jain. Bangalore.
