CogState Sport has been used throughout the world to assist with medical return-to-play decisions after concussion in contact sports since 2002. CogState Ltd is a publicly traded Australian company that has specialized in computerized cognitive testing over the past 10 years. CogState has extensive experience in providing high-quality cognitive testing solutions to large pharmaceutical companies and government agencies, with customers including Pfizer, Astra Zeneca, Lundbeck, Merck, the National Institutes of Health and the Walter Reed Army Medical Centre. CogState technology has been presented to the US FDA in support of drug therapy efficacy claims. More detail is available from the CogState website ([www.cogstate.com](www.cogstate.com)).  \nThe Axon Sports CCAT uses tasks developed by CogState specifically to measure change in cognitive function in individual people. Changes in cognitive function of individuals can occur for many different reasons, one of which is sport-related head injury. The tasks were designed to be easy and practical to administer and easy to understand. Performance on the tasks does not improve with repeated administration even over short re-test intervals. In addition, the performance measures for each task have been selected based on their sound statistical principles such that they are optimal for parametric statistical analyses.  \nFor the past 10 years validation studies have continually proven the advantages ofthe CogState tests for detecting cognitive change. The validation efforts began with establishment of the psychometric properties necessary for the detection of change in cognitive function under a variety of challenges including concussion arising from sportsrelated head injury, central nervous system (CNS) active drugs (e.g. benzodiazepines, alcohol) and physical challenges such as fatigue due to sustained wakefulness, physical exertion and stress (e.g. Falleti et al 2003, 2006).  \nSome of these challenges in healthy people have also resulted in the development of a framework for understanding and communicating the magnitude of any cognitive change detected. For example, the magnitude of changes observed in athletes who have been concussed can be understood in terms of the magnitude of the change observed with increasing blood alcohol levels or after long periods of sustained wakefulness. Two early reviews of this area specific to sports concussion assessment with neuropsychological instruments might help put this into context (Collie et al 2001, 2003a).  \nSubsequent research has investigated impairment in performance on the CogState tasks in a wide range of neurological and psychiatric conditions that include traumatic head injury, schizophrenia, depression, HIV-related cognitive impairment, Alzheimer’s disease, attention deficit hyperactivity disorder (ADHD), anesthesia and concussion. Several of these articles are included below. These additional validation studies demonstrate that in addition to being sensitive to cognitive change, performance on the tasks is also abnormal in established neurological and psychiatric diseases. There are currently many studies ongoing in which these CCAT tasks are being used to quantify and characterize cognitive impairment in a range of diseases and disorders.
