Research published Tuesday is the first to connect the dots between a common herpes virus, head injury, and Alzheimer's.

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.

A recent study by Tufts and Oxford universities reveals that head trauma can activate dormant herpes viruses in the brain, causing inflammation and accelerating Alzheimer's disease. The findings suggest antiviral drugs could be crucial as early preventive treatments to mitigate Alzheimer's risk post-head injuries.

The University of Pittsburgh researchers uncovered a surprising link between Alzheimer’s disease and herpes simplex virus-1 (HSV-1) which suggests that viral infections may play a role in the disease.

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.

The oral herpes virus appears to be linked with Alzheimer’s disease, suggesting that the common infection might play a role in the disease, a new study published in the journal Cell Reports says. Herpes simplex virus 1 -- the virus behind oral herpes -- appears to trigger the appearance of tau protein in the brain, researchers say.

A new study found a link between cytomegalovirus (CMV) and Alzheimer's disease. Here's what a neurologist wants you to know, plus how to protect yourself.
