Blast related TBI and Sports concussions: a pathway to CTE
The recent focus on sports-related concussions and the onset of CTE in the later years of athlete’s life continues to make us more aware of the long-term problems associated with “mild” brain injury, particularly problems occurring for people who have experienced multiple concussions. The pending lawsuit filed by players against the NFL, research into helmet design and better recognition of concussion’s signs by physicians and coaches are important parts of our growing awareness of the issues that are associated with multiple concussive events. Neuronotes has hosted blogs by George Visger, a retired NFL player, who has been living with the effects of multiple concussions and has become a vocal spokesperson for the issues in many forums.
As more veterans return from the theaters of war in Iraq and Afghanistan and filter back into civilian life, we are understanding the complex effects of blast-induced TBI and discerning the differences between blast and sports-related brain injuries. Both events produce a pathophysiological cascade and secondary neuronal damage. The biomechanics of two injury types are significantly different. The cummulative effect of multiple injuries from either genesis may be seen years post-injury and manifested in symptoms associated with Chronic Traumatic Encephalopathy or CTE. Clicking this linked article will provide readers with an understanding of the differences between blast-induced and sports-related TBI and the development of CTE.
