Valley of Forgetting
Jennie Erin Smith
December 14, 2025
For hundreds of years, the residents of isolated rural villages around Medellin, Columbia have been losing their memories, before, inevitably, their lives are cut short in their forties or early fifties. Jennie Erin Smith was drawn in by this medical mystery, and spent nearly a decade deeply immersed in the lives of these people, living with them; attending doctor’s visits, funerals, and autopsies. She also closely followed the doctors and researchers who overcame incredible challenges to pursue the science behind early onset Alzheimer’s.
A graduate of Columbia University, Jennie Erin Smith writes on medicine, biology, wildlife, natural history and Latin America. She also contributes several pieces a year to the New York Times science section, and writes regularly for several medical journals, primarily summarizing research in oncology and neurology. She also writes a semimonthly column on regulatory affairs in Latin America for the Regulatory Affairs Professionals Society. Jennie has also written in the past for the Wall Street Journal, the Times Literary Supplement, The New Yorker, and others. She is currently Senior Biomedicine Reporter for Science magazine. Her book Stolen World was selected among the best books of the year by the New Yorker and the Washington Post.
