“CT scans can’t detect the brain’s massive metabolic disturbance in the wake of trauma. Nor can they measure the shearing of fat-covered axons — the “white matter” that carries electrical impulses across the hemispheres of the brain and from region to region. And yet research suggests both of those processes may be key to concussion’s most damaging cognitive consequences.” LA Times 8-31-13
Concussion is described as an invisible injury ostensibly because there are no outward signs of deformity, bruising, or bones that are broken. Athletes who are “resting” as part of the step by step return-to-play protocol often feel marginalized by their teammates. Coaches strive to keep injured players in the mix by including them at practice and insisting they ride the team bus to games. This isn’t always possible when a student recovers from concussion. Many experience symptoms of light and sound sensistivity so riding the bus can be a painful endeavor. Other signs of concussion include poor concentration, lack of focus, decreased short term memory, decreased cognitive efficiency, and sometimes depression.
