Classification
Core: Sport-Related Concussion (SRC)
 
Core: One of the Core Neuropsychological Function cognitive measures should be collected: Automated Neuropsychological Assessment Metrics (ANAM), Axon Sports Computerized Cognitive Assessment Tool (CCAT), CNS Vital Signs, or Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Please note that these could be replaced by a pen or paper battery under the direction of a neuropsychologist.
Core: One of Core Symptoms Checklists should be collected: Automated Neuropsychological Assessment Metrics (ANAM), Axon Sports Computerized Cognitive Assessment Tool (CCAT), CNS Vital Signs, Child Sport Concussion Assessment Tool (Child-SCAT), Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), Post Concussion Symptom Inventory (PCSI), Post Concussion Symptoms Scale (PCS-S), Sport Concussion Assessment Tool (SCAT-3) or (SCAT-5), Standardized Symptoms Questionnaire (RPQ), or Post Concussion Symptom Inventory (PCSI).
 
Supplemental: Traumatic Brain Injury (TBI)
 
Short Description of Instrument
The Axon Sports Computerized Cognitive Assessment Tool (CCAT) uses computerized card games to test cognitive ability. Four simple tasks test processing speed, attention, learning and working memory. A baseline test represents the participant's best effort pre-injury. The post-injury report shows whether there was significant decline in test performance post-injury.
 
The test can be completed in 8 to 10 minutes via computer. Participant responds to a series of tests in a convenient location. Children should take the test under the supervision of a responsible adult.
 
Sport-Related Concussion Specific:
 
Acute: Acute timeframe: time of injury until 72 hours
Advantages: Rapid administration time (10–15 min). Effective across multiple languages. Disadvantages: Requires internet connection to administer; the test reliability, sensitivity and specificity have been questioned; and the results require interpretation by a neuropsychologist
Age Range: 10+ years
 
Subacute: Subacute timeframe: after 72 hours to 3 months
Advantages: Computerized neurocognitive assessment battery that includes four tasks that measures: 1) processing speed, 2) attention, 3) learning, 4) working memory. Uses playing card stimuli that can reduce language/reading limitations of most computerized neurocognitive tests. Brief- requires ~10 min to administer. Disadvantages: Requires a computer and software to administer. Ideally a patient needs a baseline test for best interpretation of results. Tests should be interpreted by trained professional. Limited research supporting its reliability and validity. Heavily focused on reaction time.
Age Range: Children, Adolescents, Adults – 11+ years
 
Persistent/Chronic: Persistent/Chronic timeframe: 3 months and greater post concussion
Computerized cognitive testing. Assess working memory, attention, processing speed and visual recognition memory. Has demonstrated sensitivity for distinguishing concussion, particularly regarding reaction time.
Disadvantages: Reliability has varied depending on studies. Sensitivity during post acute stages diminishes compared to acute.
Age Range: ~8+ years
Scoring
Standard scores in processing speed, attention, learning, and working memory (M=100, SD=10) pre- and post-injury.
