While there is some data suggesting brain injury rates and severity may be lower in MMA than in boxing, there is no reason to believe that the brain-rattling from MMA does not lead to the disease. There is a growing list of proven and suspected cases of CTE in former MMA athletes.
Researchers have learned much about CTE in recent years, causing leading institutions such as the U.S. National Institute of Health and the CDC to admit that the disease is caused by repeated concussive and sub-concussive blows. Despite this growing knowledge, researchers still have much to learn. Since the disease can only be formally diagnosed by brain autopsy after death, brain donation is an important step to further understanding of this deadly disease.
With this background, MMA legend pioneer Frank Shamrock has just pledged his brain for CTE research.
“As an athlete and a lifelong advocate for brain health, I am excited to announce that I will be donating my brain to the Concussion Legacy Foundation (CLF),” wrote Shamrock on his social network. “The CLF is a non-profit organization that works to advance the study, treatment, and prevention of the effects of brain trauma in athletes and other at-risk groups. Their work is crucial to the health and safety of athletes at all levels, and I am honored to be able to contribute to their mission in this way.
“I have personally experienced the impact of concussions, and I know how important it is to take proactive steps to protect the brain. By donating my brain to the CLF, I hope to contribute to their research and help advance our understanding of brain health.
“I encourage all athletes, coaches, and supporters of sports to consider supporting the CLF in their work. Together, we can create a safer and healthier future for all athletes.”
I am donating my brain to @ConcussionLF after I'm gone. Hoping to contribute to the important research on brain injuries and help improve the lives of athletes and others who have suffered from concussions. -> https://t.co/VhCfsuq8w3 #braindonation #concussionawareness

Shamrock is a pioneer of the sport and his accomplishments speak for themselves. He has joined other pioneers of the sport such as Julie Kedzie in pledging their brain to help future generations of athletes.
Thank you, Frank, for your leadership in this important field.
