Deficits in complex visual information processing after mild TBI: Electrophysiological markers and vocational outcome prognosis
Bibliographic record
Abstract
PRIMARY OBJECTIVE: To evaluate low-level to complex information processing using visual electrophysiology and to examine the latter's prognostic value in regards to vocational outcome in persons having sustained a mild traumatic brain injury (mTBI). RESEARCH DESIGN/METHODS: Event-related potentials (ERPs) were recorded to pattern-reversal, simple motion, texture segregation and cognitive oddball paradigms from 17 participants with symptomatic mTBI at onset of specialized clinical intervention and from 15 normal controls. The relationship between abnormal electrophysiology and post-intervention return to work status was also examined. MAIN OUTCOMES AND RESULTS: Participants with mTBI showed a statistically significant (p<0.05) amplitude reduction for cognitive ERPs and delayed latencies for texture (p<0.05) and cognitive paradigms (p<0.005) compared to controls. Furthermore, participants with mTBI presenting texture or cognitive ERP latency delays upon admission were at significantly (p<0.01) greater risk of negative vocational outcome than mTBI participants with normal electrophysiology. CONCLUSIONS: The findings suggest that individuals with symptomatic mTBI can present selective deficits in complex visual information processing that could interfere with vocational outcome. ERP paradigms such as those employed in this study thus show potential for evaluating outcome prognosis and merit further study.

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.
