ABSTRACT
A major barrier to advances in the field of mild traumatic brain injury assessment and treatment has been the continuous efforts to dichotomize causal factors. Mild traumatic brain injury in general and concussion in athletes in particular, offer a unique testing ground for hypotheses related to the interaction of psychological and biological variables. Most practicing clinical neuropsychologists recognize that the majority of individuals with concussion or mild traumatic brain injury recover quickly with minimal or conservative interventions. Athletes experiencing concussion often voice uncertainty regarding their health and their career. The very nature of concussion symptoms can be quite alarming and raise anxiety about threats to life or, at least, the quality of life. Symptoms comprising the post concussion syndrome are generally grouped into those of a physical, cognitive or psychological nature. The prevalence of persisting symptomatology in these three conditions is remarkably similar.
