Alan Dienstag — Alzheimer's and the Spiritual Terrain of Memory

Alzheimer's disease has been described as "the great unlearning." But what does it reveal about the nature of human identity? What remains when memory unravels? Alan Dienstag is a psychologist who has led support groups with early Alzheimer's patients, as well as a writing group he co-designed with the novelist Don DeLillo. He's experienced the early stages of Alzheimer's as a time for giving memories away rather than losing them.
