Mild traumatic brain injury, also known as concussion, occurs commonly in sport. The Centers for Disease Control and Prevention estimate that as many as 3.8 million sport-related concussions occur annually in the United States. Although many concussions resolve completely and spontaneously, almost 1 in 4 patients will go on to experience post-concussion syndrome (PCS). In the United States, PCS diagnoses have increased 100% from 2010-2015. Concurrently, recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. The purpose of this study is to explore the use of BNA in individuals who are diagnosed with PCS or have the risk of experiencing PCS due to a recent injury.
