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.

Cytomegalovirus, or HCMV, is one of nine herpes viruses that most people are exposed to in the first few decades of life. Unlike most herpes viruses, however, it is not considered to be sexually transmitted.

The research at Tufts and Oxford universities, using stem cells turned to organoids or “brains in a dish”, offers more evidence that viruses, particularly those in the herpes family that are present in the majority of adults,

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