Boxers and MMA fighters may face long-term brain damage due to repeated head trauma, a study finds.
A new study finds professional boxers and MMA fighters may suffer long-term damage to the brain’s glymphatic system, which removes waste and toxins, using a specialized MRI technique on 280 fighters and 20 controls.
While cognitively impaired athletes initially showed higher glymphatic activity—possibly a compensatory response—this function declined over time, especially with repeated knockouts, suggesting progressive failure.
The findings highlight a potential link between repeated head trauma and neurodegenerative risks like Alzheimer’s, underscoring the need for better monitoring and protective measures in combat sports.
