I wrote this a year ago. It’s still every bit as true today.
Concussion changes the brain. The changes can be temporary, or they can be permanent, but something changes inside your skull when you’re concussed.
First, the injury floods it with chemicals that aren’t supposed to be where they go. And sometimes those chemicals can actually damage healthy cells.
The connections that used to get information from one place to the next can be altered.
Depending on the type of concussion, there can be bleeding, twisting, or shearing of connections, that make it harder for information to get where it needs to go.
Concussion is like a storm microburst that suddenly appears in a normally quiet neighborhood, blowing out windows, uprooting shrubbery and trees, pulling down power and cable lines, tossing lawn furniture into the street, and seriously rearranging the garbage cans that were neatly lined along the driveway. Even a quick hit or a “ding” can do some damage.
