Frequent 'heading' in soccer can lead to brain injury and cognitive impairment

lead author Michael Lipton, M.D., Ph.D. , director of Einstein's Gruss Magnetic Resonance Research Center and medical director of MRI services at Montefiore. Further analysis revealed a threshold level of approximately 1,000 to 1,500 heads per year. Once players in the study exceeded that number, researchers observed significant injury.

"While heading a ball 1,000 or 1,500 times a year may seem high to those who don't participate in the sport, it only amounts to a few times a day for a regular player," observed Dr. Lipton, who is also associate professor of radiology, of psychiatry and behavioral sciences ), and of the Dominick P. Purpura Department of Neuroscience at Einstein.

"Heading a soccer ball is not an impact of a magnitude that will lacerate nerve fibers in the brain," said Dr. Lipton. "But repetitive heading may set off a cascade of responses that can lead to degeneration of brain cells."

Researchers identified five areas, in the frontal lobe (behind the forehead) and in the temporo-occipital region (the bottom-rear areas) of the brain that were affected by frequent heading areas that are responsible for attention, memory, executive functioning and higher-order visual functions. In a related study, Dr. Lipton and colleague Molly Zimmerman, Ph.D. , assistant professor in the Saul R. Korey Department of Neurology at Einstein, gave the same 38 amateur soccer players tests designed to assess their neuropsychological function. Players with the highest annual heading frequency performed worse on tests of verbal memory and psychomotor speed (ac
