What to expect in the new concussion guidelines


 

Dr. Wilner: I’ve been following the concussion research through the years. They did some neuropsychological testing on athletes who’ve had this many concussions or that many concussions, and they would find deficits here or subtle deficits there, but they had no baseline.

Then, there was a movement to start testing athletes before the season starts so that they could do a repeat test after concussion and see if there is any difference. Is that something we’re recommending?

Dr. Datta: Most of the time, NCAA-level – certainly where I trained – and national-level sports do testing, but it’s not everywhere. Prior guidelines have indicated that preseason testing is not required. That is largely because there has been no standardized neuropsychological testing established.

There are computerized testing options where the validity and reliability are questionable. Also, let’s say it’s a college student; they didn’t sleep all night and then they took this computer test. They would probably do worse than they would if they had received a head hit.

Just to be on the safe side, most places that have collegiate-level sports that are at a high level do preseason testing. If I were to speak personally, aside from the guidelines, I would say that it’s been helpful for me to look at the before and after, in general, overall, to make a decision about my treatment protocol.

Dr. Wilner: Let’s talk about the patient. You have a 20-year-old guy. He’s playing football. There’s a big play. Bonk, he gets hit on the head. He’s on the ground. He’s dazed, staggers a little bit, gets up, and you ask how he is feeling. He says he’s fine and then he wobbles off to the sideline. What do you do with that kid?

Dr. Datta: Obviously, the first thing is to remove him from the play environment to a quiet space. Second, either an athletic trainer or a coach would administer basic screening neurologic tests, such as “where are you, what’s today’s date, what is your name?” and other orientation questions.

They’ll also go through the SCAT – that’ll be SCAT6 starting in July – the SCAT5 symptom questionnaire to see what symptoms they have. Often, they’re using sideline testing software.

There are two things that can be used on a card to test eye movements, to see if they’re slower. They come out of NYU, coincidentally – the Memory Image Completion (MIC) and the Mobile Universal Lexicon Evaluation System (MULES) – and are used to determine whether eye movements are slower. That way, you can tell whether someone is, compared with before they got their head hit, slower than before.

Based on this composite information, usually the teammates and the head people on the team will know if a player looks different.

They need to be taken out, obviously, if there is nausea or vomiting, any neurologic signs and symptoms, or a neck injury that needs to be stabilized. ABCs first, right? If there’s any vomiting or seizures, they should be taken to the ER right away.

The first thing is to take them out, then do a sideline assessment. Third, see if they need to immediately go to the ED versus follow-up outpatient with me within a day or two.
