Repeated head injuries suffered by sports players and military personnel — a known risk factor for Alzheimer’s disease — may induce dementia by reactivating the dormant herpes virus in neural tissues, according to laboratory experiments.

The study has been published in Cell Reports. It revealed how tau protein, often viewed as harmful in Alzheimer's, might initially protect the brain from the virus but contribute to brain damage later.

Scientists from the University of Pittsburgh have discovered a surprising connection between Alzheimer's disease and the herpes simplex virus type 1 (HSV-1). Their study suggests that viral infections may play a role in developing this condition.

Researchers discovered a connection between Alzheimer’s disease and herpes simplex virus-1 (HSV-1), suggesting viral infections may contribute to neurodegeneration.
