My father had a brain injury 5 years ago. My mother has had Vascular dementia since before my fathers TBI. We have 24 hour care for my mother and they also care for my father - just not as much required. He has been progressing into more and more dementia with memory loss, hallucinations, confusion, etc. We know he has dementia, but he does not know it. He does not want to be like my mother. His doctor set up an evaluation with a neuropsychologist that involves 3 days of appointments and a 5 hour "test". I read through it all and think it is excessive at this point. He would do poorly on all phases of the test and be diagnosed with dementia. No new news. My mother was diagnosed quickly by a neurologist in a 15 minute appointment. My father has had MRIs and CT scan, but all they say is there is evidence of a previous brain injury. The other concern is that my father will "give up" if he is diagnosed officially. He is such a proud man who was always in complete control of everything, very smart. I don't want him to get depressed and give up. He is already on nemenda, although I'm thinking of asking to try aricept. Of course, if we can help him I would like to. He is 86.
