Understanding Long-Term Concussion Effects in Sports: New Biomarkers and Prevention Methods

What is it about?

This article reviews the long-term effects of recurrent concussions in contact sports, emphasizing emerging biomarkers and prevention strategies. It discusses the prevalence of concussions in sports like football, rugby, and hockey, linking them to cognitive impairments, mood disorders, and neurodegenerative diseases such as chronic traumatic encephalopathy (CTE). The review highlights advances in fluid-based biomarkers like glial fibrillary acidic protein, neurofilament light, tau, and neuro-imaging techniques for detecting and monitoring concussions. It also examines prevention measures, including protective gear, rule modifications, and educational programs, as effective strategies to reduce concussion incidence. Despite these advancements, the article notes challenges in validating biomarkers and applying neuroimaging tools clinically. It calls for future research to focus on developing personalized concussion management protocols and improving prevention strategies. The review underscores the importance of early detection and a multidisciplinary approach to managing concussions in contact sports.
