As Larry Leverenz, Ph.D, ATC, a co-author of the groundbreaking 2010 study (4) that was the first to identify such athletes noted, because such athletes have not suffered damage to areas of the brain associated with language and auditory processing, they are unlikely to exhibit clinical signs of head injury (such as headache or dizziness), or show impairment on sideline assessment for concussion, all of which test for verbal, not visual memory.

In addition, because it tests for verbal memory, the SAC can not identify athletes who may suffer measurable impairment of neurocognitive function (primarily visual working memory) on neurocognitive tests, as well as altered activation in neurophysiologic function on sophisticated brain imaging tests (fMRI), resulting from repeated sub-concussive blows to the head.

They also found that some of the athletes, none of whom suffered diagnosed concussions, didn't do as well as predicted on tests of learning and memory at the end of the season, although the study did not find «large - scale, systemic differences» in the brain scan measures, which the authors found «somewhat reassuring» and consistent with the fact that millions of athletes play contact sports for many years without developing progressive neurodegenerative disorders.

Although scientists have long suspected that RHI caused brain damage, especially in boxers, a 2010 study of high school football players by researchers at Purdue University [1,13] was the first to identify a completely unexpected and previously unknown category of players who, though they displayed no clinically - observable signs of concussion, were found to have measurable impairment of neurocognitive function (primarily visual working memory) on computerized neurocognitive tests, as well as altered activation in neurophysiologic function on sophisticated brain imaging tests (fMRI).

Using DTI, researchers at Wake Forest found in a 2014 study [26] that a single season of high school football can produce changes in the white matter of the brain of the type previously associated with mTBI in the absence of a clinical diagnosis of concussion, and that these impact - related changes in the brain are strongly associated with a postseason change in the verbal memory composite score from baseline on the ImPACT neurocognitive test.
