As Dr. Leverenz told MomsTEAM
after publication of the first Purdue study, the limitation of screening tools currently being used to assess neurocognitive
function on the sports sideline, such as the Standardized Assessment of
Concussion (SAC)[21] and the Sports
Concussion Assessment Tool 3 (SCAT3)[22], is that they test verbal memory, not the visual memory which he and the Purdue researchers found impaired in the functionally, but not clinically impaired, players who experienced at least short - term neurologic trauma from RHI.
