Alzheimer's disease is a demographic time bomb. Since 1975, the number of Americans afflicted has risen from five hundred thousand to five million; over the next fifty years, an estimated eighty to one hundred million more people worldwide will succumb to it. But it is the story behind these numbers that makes The Forgetting such a landmark work. A magnificent synthesis of history, science, politics, psychology, and profound human drama, the book explores the nature of a disease that attacks not merely memory but the very core of our human identity.
