Two very involved individuals in the concussion world are the husband/wife duo of Dr. Don and Flo Brady. You have seen their work here many times and Don is a frequent commenter. I encourage you to look at Don’s dissertation excerpts as well as Don and Flo’s myths of concussions.
A few weeks ago both Don and Flo had the opportunity to talk concussions on “Sports Doctor Radio” with Dr. Weil, you can jump straight to the .mp3 here.
Give it a listen and spread it around, Don and Flo do a good job of explaining concussions.
