TLDR
The high-participation collision sports of football and boys’ lacrosse warrant continued vigilance, but the findings suggest that focus on concussion detection, treatment, and prevention should not be limited to those sports traditionally associated with concussion risk.Abstract:
Results: In sum, 2651 concussions were observed in 10 926 892 athlete-exposures, with an incidence rate of 0.24 per 1000. Boys’ sports accounted for 53% of athlete-exposures and 75% of all concussions. Football accounted for more than half of all concussions, and it had the highest incidence rate (0.60). Girls’ soccer had the most concussions among the girls’ sports and the second-highest incidence rate of all 12 sports (0.35). Concussion rate increased 4.2-fold (95% confidence interval, 3.4-5.2) over the 11 years (15.5% annual increase). In similar boys’ and girls’ sports (baseball/softball, basketball, and soccer), girls had roughly twice the concussion risk of boys. Concussion rate increased over time in all 12 sports. Conclusion: Although the collision sports of football and boys’ lacrosse had the highest number of concussions and football the highest concussion rate, concussion occurred in all other sports and was observed in girls’ sports at rates similar to or higher than those of boys’ sports. The increase over time in all sports may reflect actual increased occurrence or greater coding sensitivity with widely disseminated guidance on concussion detection and treatment. The high-participation collision sports of football and boys’ lacrosse warrant continued vigilance, but the findings suggest that focus on concussion detection, treatment, and prevention should not be limited to those sports traditionally associated with concussion risk.read more

Nonlinear Dynamical Behavior of the Deep White Matter during Head Impact
Javid Abderezaei,Wei Zhao,Carissa L. Grijalva,Gloria Fabris,Songbai Ji,Kaveh Laksari,Mehmet Kurt,Mehmet Kurt +7 more
TL;DR: Modal analysis and advanced finite-element simulations are used to characterize the dynamical behavior of the human brain during head impact and find evidence of geometrical nonlinear effects in the deep white matter of the brain, suggesting a link between the onset of injury and the existence of local nonlinearity in brain tissue.

Is there a gender difference in concussion incidence and outcomes
TL;DR: The evidence indicates that female athletes may be at greater risk for concussion than their male counterparts, and there also is some evidence that gender differences exist in outcomes of traumatic brain injury and concussions.
