N2  - The purpose of this study was to determine the effects of headers and concussions on cognitive impairment in professional soccer players. A group of 84 active professional soccer players from several premier league soccer clubs underwent neuropsychological evaluations. The dose-response relation between the number of headers in one professional season and the number of soccer-related concussions on cognitive functioning was investigated. It was found that the number of headers in one season was related to poorer results on tests measuring focused attention and visual/verbal memory. Soccer-related concussions were related to poorer results on tests measuring sustained attention and visuoperceptual processing. The findings suggest that headers as well as concussions separately contribute to cognitive impairment.<p /> <p>Language: en</p>
