Abstract
Previously the authors noted an increase in glutamatergic tone in children with attention deficit hyperactivity disorder compared with age- and gender-matched control subjects. In this study they examine the effect of treatment on metabolite concentrations. Fourteen children with attention deficit hyperactivity disorder were investigated medication free and after treatment, using proton magnetic resonance spectroscopy. In the prefrontal cortex and striatum, metabolite peaks of N-acetyl-aspartate, glutamate/glutamine/gamma-aminobutyric acid, creatine/phosphocreatine, and choline compounds were measured, and ratios of the peaks were calculated and compared before and after treatment. The glutamate/glutamine/gamma-aminobutyric acid-to-creatine/phosphocreatine ratio decreased significantly in the striatum. No other metabolites demonstrated any change in response to medication. These findings suggest that glutamate may be involved in treatment response in attention deficit hyperactivity disorder, especially in the striatum.

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 it
