Concussions Linked to Reactivation of Brain Viruses and Increased Alzheimer’s Risk

New research reveals that head trauma can awaken dormant viruses like HSV-1, potentially triggering neurodegenerative diseases such as Alzheimer’s.

A study using lab-grown brain tissue models shows that concussions can reactivate latent viruses like HSV-1, leading to Alzheimer’s markers such as amyloid plaques and inflammation.
Repeated head injuries intensify the effects, with infected brain models exhibiting severe neuronal damage compared to virus-free tissues.
The findings suggest antiviral and anti-inflammatory treatments could serve as early interventions to prevent long-term neurodegeneration after head trauma.
The research highlights the heightened risks for athletes in contact sports and military personnel exposed to concussive forces, who may face increased chances of neurodegenerative conditions over time.
Traumatic brain injuries affect 69 million people globally each year, with significant economic and healthcare impacts, underscoring the need for preventive strategies.
