Authors: B. Joel Tjarks a,⁎, Jason C. Dorman b, Verle D. Valentine c, Thayne A.Munce b,d, Paul A. Thompsone, Shanna L. Kindt c, Michael F. Bergeronb,d,f a Sanford

To examine the diagnostic value of KD, by comparing KD with post-concussion symptom scale (PCSS) and ImPACT® composite scores.We hypothesized that KD would be correlated with visual motor speed/memory (VMS, VIS) and reaction time (RT), because all require cognitive visual processing. We also expected parallel changes in KD and PCSS across recovery.
