What it is

Rush University followed 1,939 older adults and scored their “lifetime enrichment”: books at home as a child, a library card in midlife, puzzles and games later on. The top tenth were diagnosed with Alzheimer’s at 94 on average, against 88 for the bottom tenth. Their donated brains didn’t have fewer plaques and tangles, but their thinking held up better near the end of life.

Where it stands

An association, partly based on childhood memories recalled decades later.
