Do concussed and non-concussed head trauma individuals have similar symptoms? A retrospective chart review of chronic post-concussive symptomatology
Bibliographic record
Abstract
Many head trauma patients who present with prolonged post-concussion symptoms do not meet the American Congress of Rehabilitation Medicine (ACRM) diagnostic criteria for mild traumatic brain injuries (mTBI). This population has not been extensively studied and its clinical characteristics are currently uncertain. A retrospective chart review was conducted to explore the symptomatic differences between mTBI and non-mTBI head trauma patients presenting at a concussion clinic with chronic post-concussion symptoms (PCSx). Patient information was extracted from 161 charts, of which 128 subjects met the ACRM criteria for mTBI (ACRM + PCSx), while 33 did not (non-ACRM + PCSx). These two groups were compared for demographic variables and symptomology. This study found that 20.5% of subjects presenting with chronic post-concussion symptoms do not meet ACRM criteria. No symptom-specific differences were found between the two populations in any of the categories tested. These results show that chronic post-concussion symptoms are similar in both mTBI and non-mTBI head trauma patients in the general population, suggesting a need for further research focusing on this group.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
