Zimmer didn't do his homework

On: What Happens To a Football Player's Neurons?

Diffuse axonal injury (DAI) isn't as mysterious as Zimmer implies. It's actually kind of cool from a physics standpoint. The shearing occurs at the interfaces between different types of brain tissues due to the different densities of the tissues. Also, the theory of long term neurotrauma presenting as ALS is pretty thin.
