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.
