Mild traumatic brain injury leads to reactivation of herpes simplex virus type 1, which may promote neurodegeneration and contribute to Alzheimer’s, new research suggested.

Researchers have uncovered mechanisms that may link head injuries and concussions to the emergence of neurodegenerative disease, pointing to latent viruses lurking in most of our brains that may be activated by the jolt,

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,

Repeated head injuries could reawaken a dormant virus in the brain, triggering the onset of Alzheimer's Disease and dementia, scientists have found. Researchers from Oxford's Institute of Population Ageing,

Multiple blows to the head can more than double the chance of having a neurodegenerative condition - oakstudio22/iStockphoto Head injuries may “wake up” dormant viruses in the brain and trigger dementia,
