At the Longevity Forum Science Summit, Professor Ruth Itzhaki delivered a groundbreaking talk exploring the long-suspected but often controversial link between herpes simplex virus type 1 (HSV-1) and Alzheimer’s disease. Drawing on more than three decades of research, she explained how HSV-1 can remain latent in the brain for life—reactivating under stress, illness, or injury—and how this reactivation may trigger hallmark Alzheimer’s pathology, including amyloid-beta accumulation and abnormal tau phosphorylation. Ruth walked the audience through her team’s pioneering discoveries: the detection of viral DNA in elderly human brains, the powerful interaction between HSV-1 and the APOE4 gene, and compelling laboratory evidence showing that antiviral drugs can sharply reduce Alzheimer-related changes in infected cells. Her talk challenged long-held assumptions and highlighted growing epidemiological and experimental support for a viral role in dementia, opening new avenues for prevention and treatment.
