I have been spending a lot of time with my gf's grandfather who has this disease. Holy shit this is awful. He had a freakout this morning and Gma had to call me over until her son could make it there. This Guy is a Korean war vet and he has nightmares about it and wakes up there. Some days he remembers me, some days he thinks I am one of his old buddies. I always thought cancer was the worst but IMO this tops it. He is in great physical shape but his mind is going. Much respect to the people who deal with this in a family member every day, idk if I could do it.
