Youth Contact Sports May Raise CTE Risk
Study suggests that vulnerability to CTE not limited to professional football players
THURSDAY, Dec. 3, 2015 (HealthDay News) -- National Football League football players may not be the only ones who can develop a degenerative brain disease linked to repeated concussions during decades of play, a new study suggests.
Even men who only played an amateur contact sport during their youth may face an increased risk for chronic traumatic encephalopathy (CTE), a devastating brain condition that can affect thinking, memory, behavior and mood, Mayo Clinic researchers report.
To come to this conclusion, the researchers analyzed the brains of 66 men who had donated their organs to the Mayo Clinic Brain Bank and participated in sports such as football, rugby, wrestling, boxing and basketball while in school. Their brains were compared to the brains of 198 people, including 66 women, who never played contact sports.
CTE was found in the brains of a third of the men who played amateur contact sports. But no sign of the disease was detected in the brains of those who never played contact sports, the researchers said.
"The 32 percent of CTE we found in our brain bank is surprisingly high for the frequency of neurodegenerative pathology within the general population," wrote study author Kevin Bieniek, a predoctoral student in Mayo Graduate School's Neurobiology of Disease program.
The study was published in the December issue of the journal Acta Neuropathologica.
The report comes on the heels of news last week that former NFL football great Frank Gifford had CTE when he died at age 84 in August. This latest finding significantly widens the scope of who might be vulnerable to developing the brain disease, the study authors said.
"If one in three individuals who participate in a contact sport goes on to develop CTE pathology, this could present a real challenge down the road," Bieniek said in a journal news release.
More research is needed to find out if CTE in former amateur players causes any changes in thinking and memory or behavior.
Dr. Dennis Dickson, senior study author and neuropathologist at Mayo Clinic, noted that this study is the first to use newly developed government criteria to diagnose CTE in nonprofessional athletes.
