Concussion and mild traumatic brain injury diagnosis has, until recently, existed in a state of clinical fragmentation. With more than thirty competing definitions across sport medicine, rehabilitation, emergency medicine, and military health, even experienced clinicians have faced legitimate uncertainty about when a concussion is a concussion, when it becomes a traumatic brain injury, and what the distinction actually requires. That uncertainty has consequences for patients who deserve precise diagnosis, appropriate care, and accurate documentation.

In 2022 and 2023, two landmark developments reshaped the field. The Amsterdam Concussion Consensus, produced by the Concussion in Sport Group following their October 2022 meeting, and the American College of Rehabilitation Medicine's new diagnostic criteria for concussion, co-led by researchers from Harvard and the University of British Columbia, introduced a unified, evidence-grounded framework built on a quarter century of research. This course delivers that framework in clinical detail.

Across four focused topics, Dr. Matthew Antonucci unpacks the six diagnostic criteria required to establish a TBI diagnosis, the biomechanical plausibility standards that determine whether a mechanism of injury is sufficient, the grading thresholds that differentiate mild, moderate, and severe traumatic brain injury, and the newly introduced category of suspected mTBI, which addresses patients who have been historically underserved by narrower criteria. Clinicians also gain command of the diagnostic decision flowchart that structures the entire process, including case application across sport, civilian, and medico-legal presentations.

This course is designed for licensed clinicians in chiropractic neurology, functional neurology, physical medicine, rehabilitation, and any discipline where concussion diagnosis intersects with clinical responsibility. Whether your practice includes acute sideline evaluation, post-acute rehabilitation, or complex cases involving legal documentation, the 2023 criteria provide the structural clarity your clinical reasoning deserves.
