The definition of mild traumatic brain injury (mTBI) published by the American Congress of Rehabilitation Medicine (ACRM) in 1993 has guided clinical practice and research over the past 25 years. In 2019, the Mild TBI Task Force of the ACRM Brain Injury Special Interest Group undertook an updating of this definition. This work included rapid evidence reviews, an expert survey (to rate the diagnostic importance of various clinical signs, symptoms, test findings, and contextual factors), public and stakeholder engagement, and a Delphi consensus process with an international, interdisciplinary panel of clinician-scientists. The symposium will provide an overview of these activities and then present an updated consensus definition of mild TBI. The presenters will highlight the major revisions from the 1993 definition and discuss their rationale and implications. Finally, case examples will also be presented to illustrate how the diagnostic criteria can be applied.

Learning Objectives:

Describe the methodology used by the Mild TBI Task Force of the ACRM Brain Injury Special Interest Group to update the definition of mild TBI.
Summarize the differences between the 1993 and current definition.
Apply the new definition of mild TBI to an individual patient.
