All of a sudden his appetite is diminishing. Cannot tell if he is hungry or not and eats much less than usually. He is losing his sense of direction, does not know which way to turn with the walker to get from the bathroom to the living room or bedroom. Looking at recent pictures he does not recognize himself and cannot associate his name with himself. Has constant very loose bowel movements in spite of the Immodium I give him. Has diabetes 2, high blood pressure, takes a lot of pills every day, which may be part of the cause. He is tired all day. What can I do?
