This came up when me, my sister and my father were discussing alzheimer's.
After a few minutes of nattering, my sister said the it had to be worse for some people than others - like, Terry Pratchett would suffer more from alzheimer's than an average Joe, because Terry Pratchett uses his mind more than Joe.
My father agreed, but I didn't. I can understand how someone would say the loss of a 'brilliant' mind is worse than the loss of a 'normal' mind. Surly both would suffer equally - Joe's mind might be more mundane than Terry's, but why are his thoughts, memories, personality less important?
Needless to say I wasn't listened to, but I'm curious to know how such things are seen by other people, and if I'm ridiculous for thinking people who don't have a series of popular books or great thesis would feel as great a loss.
