Mentioning Richardson made me aware of this: One of the interesting things starting to come out of studies is that women now have a greater incidence of concussions than do men due to a number of factors. In addition, the severity of a concussion and length of recovery tend to take longer in women. Also, kids suffer more concussions than we know.
"According to data published by the American Academy of Neurology, females playing college soccer suffer injury at the rate of 1.8 concussions per 1,000 games. That is greater than the combined rates of females in basketball and softball, the other sports studied. In fact, the rate of concussions for females in college soccer is greater than the rate for males in high school football (1.55). The rate for women in high school soccer was 0.97, second only to football among high school sports studied." (Concussions derail promising careers)
IMHO, the major difference is that girls and women will more readily admit to being hurt and will take more time to heal than do men. It will be interesting to see in the future if women are diagnosed with CTE as more and more girls play sports.
(Bert mentioning he doesn't recall his daughter playing soccer several years ago is just another way to keep his name in the media -- again.
