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

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
