As reported in Time and Reuters, Harvard Pop Center fellow Erika Sabbath, ScD, and Harvard Pop Center affiliated faculty member Cassandra A. Okechukwu, ScD, have published a study in Neurology that examines the effects of lifetime solvent exposure among retired French utility workers. Those at greatest risk for cognitive deficits had experienced long-term exposure, even though the exposure might have ceased as long as 30 years prior.
