There is a potential link between Alzheimer's disease and the herpes simplex virus-1 (HSV-1), which is a common cause for cold sores, a recent study suggests

Scientists have long wondered about the mysterious origins of Alzheimer’s disease, with its hallmark protein tangles and plaques that slowly devastate the brain’s ability to form memories and function normally.

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.

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.

Scientists from the University of Pittsburgh have uncovered a surprising connection between Alzheimer's disease and the herpes simplex virus type 1 (HSV-1). Their study suggests that viral infections might contribute to the development of this condition.
