Headline: Trauma to the Brain May Awaken Latent Viruses, Increasing Risk of Neurodegenerative Diseases
Subheadline: A groundbreaking study suggests that head injuries, common in sports like football and boxing, could reactivate dormant viruses like herpes, leading to inflammation and cell damage that contribute to neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

In a compelling new study published in the journal Science Signaling, led by researchers at Tufts University in the United States, a potential link between neurodegenerative diseases like Alzheimer’s and Parkinson’s has been established with head traumas. The study suggests that injuries to the head and concussions, frequently seen in sports like football and boxing, can stimulate dormant viruses like herpes in the brain, leading to inflammation and cellular damage that may contribute to the development of neurodegenerative diseases.
The study indicates that drugs targeting viruses could potentially serve as a preventive treatment after a head injury. However, the implications extend beyond the realm of sports. According to the World Health Organization, around 69 million people worldwide experience brain injuries annually, with an estimated annual cost of $400 billion.
The human body commonly hosts several potentially harmful viruses that remain inactive within cells. For instance, the herpes simplex virus (HSV-1) is present in over 80% of individuals, and the varicella-zoster virus (VZV) in over 95%. Using a laboratory-grown brain tissue model, the researchers induced traumatic injuries that activated the dormant herpes virus. In the subsequent weeks and months, symptoms typical of Alzheimer’s disease emerged, including the formation of amyloid plaques, the accumulation of tau protein, inflammation, and neuronal death. Conversely, no such signs were observed in the absence of the virus.
The study posits that repeat traumas may exacerbate these effects, and the question arises whether antiviral or anti-inflammatory drugs could be beneficial as preventive treatments after a head injury to inhibit HSV-1 activation and reduce the risk of Alzheimer’s.
Researchers emphasize that further investigation is required to confirm these findings, but the study offers an intriguing new prospect on the potential relationship between head injuries, herpes reactivation, and neurodegenerative diseases.
