Sports Related Concussions and Auditory Processing Disorders November 11, 2011.

In the News Turgeon et al (2011) report approximately 1.6 to 3.8 million potential traumatic brain injuries per year in the United States. The authors compared the auditory processing (AP) abilities of 16 university athletes. Eight athletes had previous concussions; eight had no history of concussion.

All presented with normal hearing and none of the athletes had a history of tinnitus, hearing loss, attention deficit disorder, or neurologic or psychiatric disorders. AP ability was assessed with the Frequency Pattern Sequence Test, the Duration Pattern Sequence Test, the Synthetic Sentence Identification Test, and the Staggered Spondaic Word Test.

All “non-concussed” athletes (n=8) scored within normal limits on the AP tests. Of the concussed athletes (n=8), five presented with deficits on one or more of the AP tests. The authors note, consistent with previous studies, that concussions can lead to AP deficits, despite intact and normal auditory detection results. They note that additional studies regarding concussions might explore “the possible relationship with cognitive factors, such as memory and attention.”
