The January 25th episode of the Science Magazine podcast discusses an article exploring the possible mechanisms of brain injury ocurring in near-blast conditions, where often the effects may be delayed and subtle.
Also, Easter Seals has just announced that it is funding a program that will provide access to Michael Merzenich's highly regarded Posit Science Program, an on-line program originally developed to help older patients regain and maintain their mental agility. I don't know if they have done any work with traumatic brain injury, but the program certainly shows promise.
