Cogniphobia in Mild Traumatic Brain Injury
Bibliographic record
Abstract
Cogniphobia refers to avoidance of mental exertion out of a fear of developing or exacerbating a headache. Headaches are very common after mild traumatic brain injury (mTBI) and often become chronic. Cogniphobia is hypothesized to contribute to poor cognitive test performance and persistent disability in some patients with mTBI. Eighty patients with mTBI and post-traumatic headaches were recruited from specialty outpatient clinics. They completed a battery of questionnaires (including a cogniphobia scale) and neuropsychological tests (the National Institutes of Health Toolbox Cognition Battery and the Medical Symptom Validity Test) at 2-3 months post injury, in a cross-sectional design. Participants with more severe headaches reported higher levels of cogniphobia. Cogniphobia was associated with lower performance on memory testing (but not other cognitive tests), independent of headache severity. Participants who avoided mental exertion also tended to avoid physical activity and traumatic stress triggers. The findings provide preliminary support for the role of cogniphobia in persistent cognitive difficulties after mTBI, and suggest that cogniphobia may reflect a broader avoidant coping style.

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.
