Interviewer: If somebody has a concussion and they don't have access to the impact, how do they know if they're healed, for lack of a better term?

Dr. Maroon: Again, you're left with subjective reporting of symptomotology. So, they get through the first two stages, they're asymptomatic at rest, they exercise, "I feel fine coach." But the subtle things of reaction time with the impact tests, we can measure that with 1/100ths of a second, which is frequently impaired even though they may look and sound very well when they're tested. Their reaction time, their ability to process information isn't quite as sharp. Their memory isn't quite as good and we can, we now have, as I said, 5 million baseline tests and close to 10 million tests that we've done with the impact, so we're able to validate this even if they've not had a pre-existing impact test as a baseline. We have enough controls, age, gender, match, that we can extrapolate good data from it.

The dangers of returning from a concussion before a person is healed is becoming better known. But how do you know if a person is better? Neurosurgeon Dr. Joseph Maroon discusses some things to look and test for even if that person looks and feels 'normal'.
