Cognitive Evoked Auditory Potentials and Neuropsychological Measures Following Concussion in College Athletes
Over 800 athletes suffer from concussion in the United States each day, resulting in over 300,000 concussions each year. Recent data has revealed that the incidence of mild traumatic brain injury is on the rise for many different sports, placing athletes at higher risk. Damage is caused by the shearing of axons, which results in swelling and loss of limited function. Electrophysiologic techniques, specifically event-related potentials are one of the most frequently used cognitive assessments. Event-related potentials are a non-invasive method to gather a baseline of cognitive processes and to evaluate cognitive deficits. The current study investigated the sensitivity of event-related potentials in the identification of cognitive deficits following concussion in college athletes. Neuropsychological and electrophysiological measures were collected from two groups of participants allocated by injury versus non-injury. Results from the study found important differences between non-concussed and concussed athletes using electrophysiological measures and neuropsychological test measures.
