I have noticed that more in the last couple of years, maybe the last two to three years, maybe it took a little bit of time to make its way to Buffalo.

Mild traumatic brain injury is a category of bran injury that includes concussion, with concussion being at the mildest end of that spectrum. So sports concussion, for example, would be a subset of mild traumatic brain injury, all of the patients in this study received a CT scan to evaluate for brain bleeding or skull fracture and may have had a neurological deficit when they came to the emergency room. While that type of injury can be classified as' mild,' it's a lot more severe than a sport-related concussion typically would be.

While that type of injury can be classified as' mild,' it's a lot more severe than a sport-related concussion typically would be, all in all, I think it's a good study for helping to predict who is at risk for depression and PTSD after a traumatic brain injury sustained in a car accident or from an assault.

We don’t know for sure what the cause of difficulty with concentration and memory in school is but a common report is that of cognitive intolerance ; that is, students can not do their work for sustained periods of time before becoming very fatigued and thus unable to process new information, academic problems likely reflect an issue of cognitive intolerance due to an inefficient brain after concussion.

Nobody finds it useful to grade concussions any longer because the initial treatment is the same for all concussions : remove immediately from at-risk activity.

There is some concern for potential long-term damage, but we don't know who is really at risk. We need more research.

Prevention is always better than trying to treat something.
