And the mood changes... crying, then nasty. I heard when a person has the disease, they know they have it. Mom denies it all the way. I told her she has it and iIasked her the questions the doctor asked. What year is it. What month. Who is President. And she does not bathe. She wears the same clothes. My father does all he can, but with the chemotherapy and two hip replacements, its just an impossible situation. But he refuses to put mom in an assisted living home. It is hopeless.
