Now, off to the helmet sticky with this one.
It might simply be a shift in recognition and diagnosis. While the diagnosis of death has alays been pretty good, that on non fatal head injuries has undergone a sea change in terms of recognition. Many more minor concussions that previously wouldn't have been reported now are, which creates the illusion of increased incidence.
It's hard to factor the impact of the change in protocols, so it might make sense to compare deaths only.
