Repetitive Head Impacts Can Affect Learning in College Athletes

Repetitive Head Impacts May Reduce Learning in College Athletes  A new study suggests that athletes who suffer head impacts during contact sports, such as football or hockey, may see a decrease in the ability to acquire new information.

The study involved college athletes at three Division I schools, comparing 214 athletes in contact sports to 45 athletes in non-contact sports such as track, crew, and Nordic skiing.

The contact sport athletes, who wore special helmets that recorded the acceleration speed and other data at the time of any head impact, experienced an average of 469 head impacts during the season.

All of the athletes took tests of thinking and memory skills before and after the season. Additionally, 45 contact sport athletes and 55 non-contact sport athletes also took an additional set of tests of concentration, working memory, and other skills.

“The good news is that overall there were few differences in the test results between the athletes in contact sports and the athletes in non-contact sports,” said study author Thomas W. McAllister, M.D., of The Geisel School of Medicine at Dartmouth. “But we did find that a higher percentage of the contact sport athletes had lower scores than would have been predicted after the season on a measure of new learning than the non-contact sport athletes.”

About 22 percent of the contact sport athletes performed worse than expected on the test of new learning, compared to four percent of the non-contact sport athletes.

McAllister noted that the study did not find differences in test results between the two groups at the beginning of the season, suggesting that the cumulative head impacts that had been sustained over previous seasons did not result in reduced thinking and memory skills in the overall group.

“These results are somewhat reassuring, given the recent heightened concern about the potential negative effects of these sports,” he said. “Nevertheless, the findings do suggest that repetitive head impacts may have a negative effect on some athletes.”

The research is published in the May 16, online issue of Neurology, the medical journal of the American Academy of Neurology.
