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

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.

Repeated head injuries could trigger Alzheimer’s disease by awakening a dormant virus in the brain, a study suggests. Many people are infected with the virus that causes cold sores - herpes simplex virus type 1 (HSV-1) - during their lifetimes.

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.

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