question: my husband has hallucinations and is very slow and has a lot of trouble talking, if we play a game about half way thru he is dropping off, in the last few months has lost 20 pounds. he is 87, he seems to know what his is saying, just takes a lot of time to get it out. We are going to the VA for a CT scan of his head and his red blood cells are high and we are going to a hemotologist on Monday. What do you think, I think it is dementia his primary doctor said it s because he doesn t sleep good at night, I think he is really off base with his answer, well anyway we are going to the VA which makes more sense.
