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.

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

A groundbreaking study reveals that concussions and repetitive head injuries in sports could trigger latent viruses in the brain, such as HSV-1, leading to Alzheimer's disease. Researchers suggest that early use of antiviral drugs might prevent these effects,

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.

A chronic gut infection caused by a common virus may be linked to the progression of Alzheimer ’s disease, a new study has found. 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.
