Ive never had to deal with Alzheimer's. Although my dad had a cancerous brain tumor back in 94. It was sitting in the middle of his brain and resting on the brain stem. They were able to remove the majority of it and treat the rest with Chemo. However, they short circuited some things and I had to watch him over the next 20 years go from a grown man to a child. He passed away 3 years ago, but let me tell you that was certainly difficult as well.
