Concussions used to be a joke. You know, all those cartoons and slap stick movies with people getting knocked out, then waking up and shaking it off as if it were nothing. Ha, ha, ha! Well, it wasn’t nothing. It’s really something.
So what exactly is a concussion? It is a temporary loss of brain function caused by a blow to the head. That’s what we used to think was the end of it. But we now know that it can lead to many long-lasting physical, cognitive and emotional symptoms.
And we are finding out more and more about the hidden damage concussions can cause. Concussions are a kind of TBI (traumatic brain injury) that can lead to life-long disabilities. Take “Lou Gehrig’s disease” (amyotrophic lateral sclerosis, or “ALS”) for example. Yesterday’s New York Times reported that Lou Gehrig might not have actually had the disease named after him. Rather, he might have had what doctors now understand to be a TBI which manifests itself through symptoms mimicking ALS. The Times reports that those afflicted with the disease probably were predisposed to it by genetic factors, but concussions serve as the catalyst.
