My grandmother fell victim to the disease. In the first noticeable stages, she engaged in erratic behavior and often reverted to earlier times when speaking. I see in McCain what I saw in my grandmother.
Cram your shit up your own ass. Anyone....even you....can look up signs and symptoms of disease on the internet. I don't need a medical license to do that, asshole. Why don't you look up the phrase "irreversible dementia" for yourself.
