New study findings by researchers from the Albert Einstein College of Medicine in New York City suggest that soccer players who engage in “heading” balls more than 1000 to 1500 times a year may develop changes in the brain that are similar to those seen in people with mild traumatic brain injury or concussions. These results were presented at the Radiological Society of North America's 2011 Conference held in November.
