Look at the situation from a positive perspective. Always remember that you cannot change the person. Otherwise, you would just end up frustrated as the patient mounts resistance. Instead, try to accept the behaviors as a reality that come with the disease. Work through this reality. Do not argue or convince him into doing the thing you think is better for him. When, for example, your patient wants to take a walk. Do not stop him from doing so. Or, if he insists on sleeping on the floor, manage to put a mattress on which he may lay down. And if the patient wants to cook, provide him with something to mix his ingredients in.
