My grandfather had Alzheimer's. I visited him in the nursing home. He mistook me for his late brother, and presumed that we were about to go on a trip, that he had already taken decades ago, to the Baseball Hall of Fame.

I didn't know what to do so I just played along with it. We spent the next hour having the most in depth and amazing conversation about the history of hist Baseball experiences from his youth. He remembered nearly everything from that period of his life and we discussed it in exceptional detail.

I walked away both elated that we could have that moment and incredibly sad that most victims of this disease seem entirely trapped within it. They're still in there. They're still that same person.
