Should it be performed by neuropsychologists or team doctors?

The dual roles of neuropsychological testing in sports concussion are well established. Neuropsychological assessment may aid understanding of the brain structures and processes underlying concussion and the Post Concussion Syndrome. Although this is a primary goal of neuropsychologists working with concussed athletes, a more immediate role lies in facilitating effective post concussion medical management of individual athletes.1 Over the past two decades, “paper and pencil” neuropsychological tests have been used to aid concussion management in many sports.2–4 However, use of such tests has generally been limited to athletes performing at the elite level. The wide scale use of paper and pencil tests in sports medicine is limited by the requirement that test administration and interpretation be undertaken by trained personnel—for example, neuropsychologists, and that administration is usually on a one-to-one basis. This makes neuropsychological assessment of entire sporting teams time consuming, expensive, and beyond the means of most junior and amateur contact sporting organisations.

These practical limitations, combined with the psychometric limitations of some paper and pencil tests,5 have led to the development of a number of computerised neuropsychological test batteries.6,7 These computerised batteries are designed specifically for widespread use in sports medicine, and provide a relatively inexpensive alternative to paper and pencil assessment. Test administration may be accomplished on a large number of athletes over a short period of time, as many athletes may be assessed simultaneously and test administration may be self-guided. If designed appropriately, computerised tests may be both more reliable and more sensitive to the cognitive effects of concussion than paper and pencil tests.5 Two questions that arise from the increasing proliferation of computerised neuropsychological assessment in sports concussion are (1) “What role can neuropsychologists play in the administration and interpretation of computerised neuropsychological tests?”; and (2) “Is it appropriate for medical practitioners to independently interpret the results of computerised neuropsychological tests?”


As specialists in brain behaviour relationships, neuropsychologists may offer a level of insight into the athletes' post-concussion cognitive function not available to a non-neuropsychologist. Ideally, a neuropsychologist would administer and interpret the results of every neuropsychological test conducted in sports medicine. One need only investigate the number of athletes involved in contact and collisions sports to realise that this is simply not feasible. For example, the Federation Internationale de Football Association (FIFA) oversees soccer competitions in 186 countries with over 200 million registered participants. In the United States, it is conservatively estimated that 300 000 sports related concussions occur every year.8 Given the recognised need for baseline assessment in sports concussion,1 one-on-one neuropsychological testing of this many athletes is impossible. Computerised assessment requiring minimal or no supervisor assistance with automated reporting of results is the only current available method for completing this daunting task.

This does not mean that neuropsychologists are redundant in sports medicine. The computerised neuropsychological tests currently available were all designed by neuropsychologists who recognised the limitations of paper and pencil assessment in sports concussion. Also, many professional sporting teams hire consultant neuropsychologists as part of their concussion management programmes. An appropriate role for neuropsychologists lies in the assessment of athletes whose post-concussion cognitive impairment, as measured by computerised tests, has not resolved or is of a severe nature. In such instances conventional neuropsychological approaches can help manage the injury and further refine understanding of the injury. Neuropsychologists can also become involved in developing rehabilitation strategies to aid recovery in such athletes.


The computerisation of neuropsychological tests has meant that reports detailing the athletes' post-concussion cognitive function are available immediately to the team doctor. We propose that it is appropriate for team doctors to interpret these reports in the absence of a neuropsychologists opinion. This proposal is based on two major conclusions, described below.

The immediate role of neuropsychological assessment in the medical management of athletes is to determine whether a change in cognitive function has occurred from a baseline, or pre-participation, assessment. As the pathophysiological basis of sports concussion remains unknown,9 there is no advantage in attempting to determine why cognitive function has changed in an individual athlete. That is, in most cases of concussion, medical management of the athlete is not aided by identifying patterns of spared and impaired cognitive abilities, as per conventional neuropsychological assessment models. Thus, the output from computerised neuropsychological testing is either: (a) “yes, cognitive function has changed after concussion”; or (b) “no, cognitive function has not changed after concussion”. This is reflected in the automated reports arising from currently available computerised batteries, at least two of which provide a simple “yes” or “no” result.6,7 We propose that interpretation of such reports does not require neuropsychological expertise. Rather, the medical management challenge lies in incorporating these results with the results of clinical investigations. This leads to our second point, below.

Effective medical management of concussed athletes involves more than neuropsychological assessment. Among other factors, team doctors must consider the athletes' clinical signs and symptoms, the mechanism of injury, the presence or absence of loss of consciousness (LOC) and post-traumatic amnesia (PTA), and the results of other investigations—for example, neuroimaging, when making return-to-play and return-to-training decisions. Medical management also extends beyond return-to-play decisions to include pre-participation examinations, sideline diagnosis and assessment, indications for immediate hospital referral, and exit medical examinations. In this context, the team doctor (or another experienced medical practitioner) is the only person with sufficient knowledge and experience to integrate the results of these investigations with the results of neuropsychological assessment and make reasonable decisions.


Due to practical constraints, it is unreasonable to suggest that administration and interpretation of computerised neuropsychological tests should always be undertaken by neuropsychologists. Team doctors are well equipped and sufficiently knowledgeable to integrate the results of computerised neuropsychological tests into their athlete medical management procedures. Despite this, neuropsychologists can make significant contribution to sports medicine and athlete medical management.
