Identification of concussion/mild traumatic brain injury (mTBI) remains a clinical diagnosis with no "gold standard" diagnostic tool. In addition, there are many clinical diagnostic criteria, with the World Health Organization noting 38 different suggested diagnostic criteria in a 2014 report.1-4 The Standardized Assessment of Concussion (SAC) was developed for acute "sideline" assessment of concussion in the mid to late 1990s. 5 The SAC consists of assessments of orientation to time, day and date, immediate recall, concentration, and delayed recall. The total score achievable is 30, and in many applications, a score of 25 or higher is considered "normal," based upon this score having the maximum sensitivity and specificity. 6 The SAC has been widely used as a sideline screening tool for concussion in many sports.5•7-13 In 2004, the SAC was included with other assessments to produce the Sports Concussion Assessment Tool (SCAT), currently in its third iteration.
