Mr. Andrews was listless this morning, staring at his food as if he didn't know what to do with it. Normally he eats a big breakfast and jokes with the staff about his ability to eat a lot and not gain weight. He urinated in the bed, something he has never done. His caregivers wonder what could be going on with Mr. Andrews. Is he depressed? He did lose his wife 3 months ago. Is he starting to get dementia?
