Study: Concussion Tests’ Marketing Outpaces Scientific Evidence

While computerized neurocognitive testing for concussions is widely used in amateur and professional sports, according to a recent study in Neuropsychology Review, little research over the past decade proves its effectiveness. The convenient computerized tests are typically used to establish a baseline to use as a point of comparison after an athlete is injured. But, because concussion symptoms can vary widely across individuals, clear documentation of mild brain injury can be difficult. After a detailed analysis of such testing, the authors concluded that evidence on reliability and validity of the tests was not consistent. As a result, the researchers urge caution with their use and suggest a need for more peer-reviewed studies. “Neurocognitive testing is an important component of the concussion assessment, but should not be used as a stand alone method to diagnose injury or determine an athlete’s level of recovery and fitness to return to play,” said co-author Michael McCrea, director of brain injury research at the Medical College of Wisconsin.
