It appears that middle-class U.S. friendships are not generally expected to bear the weight of deep and diffuse obligations to care. More like pleasure crafts than lift rafts, they are not built to brave the really rough waters—and [dementia is] rough, corrosive, bitter waters indeed. Dementia seems to act as a very powerful solvent on many kinds of social ties. I doubt that many friendships survive its onset.
