The Clinical Relevance of Behavior Testing in Animal Models of Traumatic Brain Injur

Research output: Contribution to journalReview ArticleResearchpeer-review


Traumatic brain injury (TBI) is a leading cause of morbidity worldwide, with patients often suffering from consequences such as cognitive deficits, social abnormalities, anxiety, depression, pain, and motor dysfunction. As these impairments often have a significant impact on the patient’s quality of life, a key aim of therapeutic intervention in TBI is to mitigate these effects. Translational strategies to develop such interventions have heavily featured animal models of TBI. To assess the efficacy of interventions in these models a range of behavioral outcomes are employed. However, in light of the past translational failures that have plagued the TBI field, the clinical relevance of these preclinical behavioral tests is now being scrutinized. This article will summarize the behavioral consequences of TBI in humans; describe common methods available for testing cognition, social function, motor ability, pain, as well as depression- and anxiety-like behaviors in animal models of TBI; provide an overview of the results from TBI animal model studies that have employed these methods; and discuss these preclinical behavior methods and findings in terms of their relevance to the clinical TBI setting. We conclude that there is translational value in these methods and their related findings, but also suggest strategies and future research to improve the clinical relevance of behavior testing in animal models of TBI
