Expert perspectives and opinions on diagnosing mild traumatic brain injury


  • A panel of experts have identified observable signs, symptoms, test findings, and contextual factors are of perceived importance for diagnosing mild traumatic brain injury (TBI). Many of these have not been considered in previous diagnostic frameworks.

Why this matters

  • Many versions of the 1993 American Congress of Rehabilitation Medicine (ACRM) mild TBI definition have been published by various groups. However, diagnostic criteria vary between different versions.

  • The lack of a universal case definition for mild TBI can be problematic for clinical practice. In 2019, the ACRM Brain Injury Special Interest Group Mild TBI Task Force began to undertake an update to the 1993 ACRM definition of mild TBI.
