Are There Subconcussive Neuropsychological Effects in Youth Sports? An Exploratory Study of High and Low Contact Sports
This exploratory study was designed to examine the neuropsychological effects of sports related head trauma specifically, repetitive subconcussive impacts or head blows that do not result in a diagnosable concussion. The researchers compared the Immediate Post Concussion Assessment and Cognitive Testing (ImPACT) neurocognitive test scores of 2 groups of nonconcussed youth athletes (n 282) grouped according to the frequency of concussions in their respective sports, with the assumption that more subconcussive impacts occur in sports in which there are more reported concussions. The results indicated that high contact sport (football) athletes had significantly poorer performance in processing speed and reaction time compared with athletes in low contact sports (wrestling, soccer, baseball, judo, and basketball) This study into the effects of repetitive subconcussive head trauma tentatively raises concern that participation in high contact sports, even without evidence of a diagnosable concussion, could result in lowered neuropsychological functioning among high school athletes. Limitations of this exploratory research effort are discussed.
