The medical question
How should research measure and protect a fighter’s neurological health over time?
This evidence informs questions about cumulative exposure, neurological assessment and long-term health. The Fight Medicine Research Institute examines the study design, the fighters included and the outcomes measured when developing its own research questions.
Summary
Investigators applied traumatic encephalopathy syndrome research criteria and compared MRI, cognitive and biomarker measurements between classified groups of professional fighters.
What the abstract reports
- Of 176 professional fighters who were 35 or older or retired (110 boxers and 66 MMA fighters), 72 (41%) met the NINDS consensus criteria for traumatic encephalopathy syndrome.
- The group meeting the criteria had lower regional brain volumes and lower scores on reaction time, psychomotor speed and Trails A.
- Fighters meeting the criteria tended to be boxers, to have started fighting younger, to have had more professional fights and to have been knocked out more often.
