Progress in Concussion/Traumatic Brain Injury Science and Clinical Care Over the Last 40 Years.

Abstract

This Special Communication summarizes how knowledge and clinical practice have evolved over the 40 years since the Journal of Head Trauma Rehabilitation's topical issue (volume 1, issue 2) on "Minor Head Injury." We review important insights from this 1986 issue and highlight how research since has refined our understanding of concussion/traumatic brain injury pathophysiology, recovery, and long-term effects. We also discuss shifts in terminology and outline how assessment and rehabilitation approaches have developed over time. Finally, we call attention to areas of ongoing uncertainty and innovations that could help resolve them.
