I took care of my dad living with him the last six months of his life. Right before he died he was in the hospital due to pneumonia. He had trouble swallowing due to the dementia. My mother was alive when he was diagnosed but she was in denial and she died almost two years before him. She never mentioned what type of dementia the Dr said he may have. At the hospital they had in his chart he had Alzheimer's dementia but I didn't see many of the Alzheimer's symptoms. Do they use Alzheimer's as a dementia catchall?
