Clinical test instrument development to identify and track recovery from concussion.

Over the past 25 years, neuropsychological assessment has been the prominent clinical method for evaluating neurocognitive functioning and monitoring recovery following mild traumatic brain injury (mTBI), or concussion. During this time, neuropsychological assessment of concussion has developed extensively starting from traditional paper-and-pencil tests to the more current computerized assessment batteries that are specifically designed for evaluating mTBI. Concussion assessment is complex and challenging due to the highly variable neurocognitive behavior and the wide range of diverse symptoms that follow an injury.
