There’s a whole population of “experts” who are hired by insurance companies to testify that people haven’t really been hurt.

There’s a subset of this group comprised of neurologists, neuropsychologists and physical medicine doctors who are “concussion deniers.”

They love mythology. Particularly if it ties in with historic misperception. The concept that someone must be knocked out (or worse) to suffer a concussion is part of the playbook.

Even if they don’t say that loss of consciousness is a sine qua non, they imply it.

“Well, the plaintiff didn’t even lose consciousness!”

Like any myth, there are a couple of problems with this one.

First, people usually don’t know whether they’ve lost consciousness. They’re not good historians. (Rather than asking a question about the ultimate issues, it’s usually better to ask what they remember before and after the wreck to see if there are gaps in memory.)

Second, and most importantly, while loss of consciousness can be a basis for diagnosing a concussion, it’s not a requirement for the diagnosis.

Here’s a table from the DOD and VA that we’ll be referencing through this mythology series.

You can see that for a mild TBI there doesn’t have to be any loss of consciousness. (0 < 30 min)

TBIs—especially mTBIs (concussions)—are both so common and so commonly un-diagnosed and untreated.

Sometimes benign neglect works. I treated my rosacea with it. Success! (Or it could have been reducing my Diet Coke consumption by a half-rack a day.)

But there’s a sizable minority of people (the “miserable minority”) who don’t recover from mTBIs. For them timely intervention is essential. Without it their lives start to spiral and it’s very difficult to get back on track.
