Right Brain: Concussion (film)

Abstract

As many as 4 million athletes in the United States experience mild traumatic brain injury (TBI) each year, 300,000 of whom are diagnosed with the clinical syndrome of concussion. 1 This estimate might account for a minority of identified concussions, with up to 92% going unrecognized and untreated. 1 Defined by its absence of any structural injury on conventional neuroimaging, concussion is caused by an impulsive force to the cranium resulting in a constellation of neuropsychiatric manifestations including headaches, dysequilibrium, cognitive slowing, and fatigue. 2 While many concussions do not produce clinically evident sequelae, an estimated 5.3 million Americans currently have TBI-related disability. 1
