a similar battery of tests as well as assessing balance problems on college athletes who experience concussions, Dr. Guskiewicz also found poorest performance on the day following the concussion.

“We are learning that we have underestimated how long it takes to recover from a concussion,” noted Dr. Kelly.

In Dr. Echemendia’s study, the athletes’ brain functioning assessed by these tests usually was the worst at 48 hours after the concussion. Interestingly, few of the athletes reported any concussion symptoms at this time. “This suggests that these tests can give us some additional information over and above the symptoms and tells us that the symptoms in and of themselves may not be enough,” said Dr. Echemendia.

Most of the athletes’ scores did not return to the levels they were at the beginning of the study until 10 to 30 days after the concussion. “We are learning that we have underestimated how long it takes to recover from a concussion,” noted Dr. Kelly.
