Cognitive Impairments From Concussions May Linger Even When Symptoms Are Gone

One of the most frustrating parts of recovering from a brain injury is feeling normal but still being functionally impaired. Just because your symptoms are gone doesn’t mean your brain has fully healed.

This hasn’t always been the way we understood things however. In fact, until very recently concussions were almost entirely judged symptomatically, but new research into the brain injury has shown that symptoms don’t necessarily reflect how healed a patient is.

A new study from Columbia University in New York confirms this, as they’ve shown that college football players with concussions showed mild cognitive impairment on the Concussion Resolution Index, even after symptoms subsided.

The study examined a group of 70 Ivy League college football players who had suffered concussions. From that group, 39.4% continued to show subtle impairment during computerized evaluations after their standard symptoms had been resolved.

“The key thing here is that despite reports of [resolution] of symptoms by the athletes, we still saw that nearly 40% of the concussed athletes showed significant deficits in their neuropsychiatric testing,” Tanzid Shams, leader of the study from Columbia University, told MedPage Today at the American Neurological Association’s annual meeting.

“And this is important because an athlete can report resolution of symptoms, but they still may have lingering cognitive deficits, and the key thing we have to watch out for is that someone doesn’t get a second or a third concussion during the time that they are vulnerable.”

This could have a significant impact in the future on concussion guidelines. Standard practice for a player diagnosed with a concussion is to be pulled from action for at least a week, until symptoms have subsided and the player has been cleared by a doctor. In general most symptoms are resolved within a week, but under these guidelines players who are still concussed are prevented from putting themselves back at risk.

If the brain is still vulnerable following the resolution of symptoms, it is likely players may need to be removed from play for longer periods, with further testing done to confirm if they are ready to return to play. In leagues like the NFL where a shocking number of players are out weekly from brain injuries, a change like that could shake up the game even more.

    It’s been close to 2.5 years since I had my concussion. My headaches are not as bad anymore but I am still having troubles in my everyday activities in regards to planning, concentrating, multi tasking and other similar issues. I am currently employed as a roads supervisor for a municipality and am in charge of organizing and lining up work for 35 employees. This also includes going out and assessing different issues and prioritizing them in Order to set up work. When things have to change due to various reasons such as employees calling in sicker job time lines changing I have a difficult time focussing and re organizing especially if others are in the room. Just Wondering how long this will go on

      I can’t work. I am still suffering with post concussion syndrome… fatigue, confusion, stuttering, headaches, cognitive problems. I am trying cold laser therapy. I have tried other therapies. Weed helps the sleep disruption. I don’t know how you work. I can’t. Did you read the studies … say that the damage to the brain can be permanent. Drs won’t say that. I have seen so many drs. I have been angry because they won’t say it can be permanent
