Room: Oak Alley


The purpose of this presentation is to examine evidence for evolving risk and prognostic factors of outcomes following concussion including on-field and sub-acute signs/symptoms and cognitive impairments, post-traumatic migraine (PTM), ADHD/LD, and other factors. The signs, symptoms, and impairments (i.e., cognitive, physical, vestibular ocular) presented by athletes with a sport-related concussion and the concomitant approach to the injury are highly individualized (McCrory et al., 2009). The inconsistent presentation of concussion has warranted attention from researchers to identify factors that influence the risk and recovery from concussion. Established health history factors that include age (Field, Collins, Lovell, & Maroon, 2003), sex (Covassin, Elbin, Harris, Parker, & Kontos, 2012), and history of previous concussion (Covassin, Stearne, & Elbin, 2008; Iverson, Echemendia, Lamarre, Brooks, & Gaetz, 2012) are known to influence concussion risk and recovery outcomes. In addition, injury-specific temporal factors including on-field dizziness (Lau, Kontos, Collins, Mucha, & Lovell, 2011), sub-acute post-traumatic migraine (Mihalik et al., 2005), and post-traumatic amnesia (PTA: Collins et al., 2003) influence the severity and recovery from concussion. Recently, researchers have identified additional health history and injury-specific factors that influence outcomes following sport-relate concussion and should be considered by sport psychology professionals who work with concussed athletes. In this presentation we will critically examine evidence for established and emerging factors that influence concussion risk and outcomes. In addition, the results of several new clinical studies that examine the influence of migraine history, PTM, learning disability/ADHD, and vestibular ocular impairment will be analyzed. The role of these factors in assessment and management of sport-related concussion will be emphasized.
