I have patients who are concerned about historical injuries. Is there any length of time after which the Cognitive Health Assessment™ is no longer useful?

No, the Cognitive Health Assessments™ offered are extremely sensitive measurements and as a result can be useful in both the acute and chronic phases of injury. You can explore more on how our assessments benefit individuals years removed from their injuries in the publication Disruption of Function: Neurophysiological markers of cognitive deficits in retired football players  and in the award winning series Collision Course.
