As the blog progresses we will republish posts that garnered a lot of page views, especially those that have to do with research or opinion that are consistent with the theme of concussions as we currently understand them. This post originally appeared November 2010.
Research is beginning to suggest that chronic exposure and delayed recovery from TBI (see concussions) is directly effecting executive functioning of the brain. In August 2010, the Journal of Clinical and Experimental Neuropsychology published an abstract on an experiment from Finland.
Hartikainen, Waljas, et al performed executive reaction time testing, standard neuropsych tests and diffusion tensor imaging on their subjects and found that there were significant differences in scores between those that still had symptoms and those that have fully recovered. The issue and problem that presented itself is that the scores indicated trouble in executive functioning of the “still-injured” brain as opposed to the recovered.
MindDisorders.com defines Executive Function as;
The term executive function describes a set of cognitive abilities that control and regulate other abilities and behaviors. Executive functions are necessary for goal-directed behavior. They include the ability to initiate and stop actions, to monitor and change behavior as needed, and to plan future behavior when faced with novel tasks and situations. Executive functions allow us to anticipate outcomes and adapt to changing situations. The ability to form concepts and think abstractly are often considered components of executive function.
These are high level abilities that influence the most basic things like attention, memory and motor functions. Along with the basics the executive functions of the brain allow each of us to adapt and perform in real life situations. Permanent or temporary deficits to the executive functioning of the brain are associated with; obsessive-compulsive disorder, depression, ADD/ADHD, Tourette’s Syndrome, schizophrenia, and autism.
There has been suspicion about how concussion symptoms specifically affect the brain, this could be our first hard evidence of the executive function angle. As with previous studies, actually quantifying executive function is difficult, more research is needed and welcomed.

Commentary on Proposal for Limiting Contact in HS Football
23 MaySince the letter went out via email and on this blog I have had many responses from many different people and places. There have been questions and comments about what was written and in this post I will address as many as possible.
Let us begin with the deafening silence on the issue. As in only one email in response (24 sent out) from the IHSA and its board of directors. That response was as follows; “Thanks, Dustin”. Yup that is it. Not that I was expecting an invitation to HQ to break this down but maybe some questions or comments or stonewalling, nope – nothing.

Cost became a hot topic on this proposal. Yes, I concede that hiring an athletic trainer will cost you some money, but seriously would you send you kid to a swimming pool without a life guard? It is the same thing as sudden death, Continue reading →
