The Adams helmets were ranked very low on the scale designed by the researchers. Since Adams did not have any helmets that really scored well, they decided to attack the methodology of the research and defend their current products. Once again, this should surprise nobody.
The issue that I have with this whole thing is that helmets were NEVER designed to prevent TBIs. They were designed to prevent skull fractures. TBIs occur when the brain slams against the inside of the skull. Since the brain is suspended in cerebral spinal fluid, no helmet is going to prevent the brain from moving when the head is violently shaken. The best way I have heard this described is an analogy of a padded raw egg. It doesn't matter how much padding you put on the egg to prevent the shell from cracking, if you shake the egg hard enough, you will scramble the yolk inside.
While I applaud the manufacturers for their efforts in creating a better helmet, the manufacturers really need to quit telling everybody that their helmet will prevent TBIs. They won't. They may be able to decrease the severity or the frequency a little, but until we can figure out how to slow the decelerational forces during collisions, I don't see helmets changing the rate of TBIs very much.
