Clinical, imaging genetics and deformation based morphometry study of longitudinal changes after surgery for intractable aggressive behaviour
Bibliographic record
Abstract
ABSTRACT Intractable aggressive behaviour is a devastating behavioural disorder that reach 30% of psychiatric aggressive patients. Neuromodulatory surgeries may be treatment alternatives to reduce suffering. We investigated the outcomes of bilateral amygdala radiofrequency ablation in four patients with intractable aggressive behaviour (life-threatening-self-injury and social aggression) by studying whole brain magnetic resonance imaging and clinical data. Post-surgery assessments revealed decreases in aggression and agitation and improvements in quality of life. Aggressive behaviour was positively correlated with serum testosterone levels and the testosterone/cortisol ratio in males. No clinically significant side effects were observed. Imaging analyses revealed preoperative amygdala volumes within normal range and confirmed appropriate lesion locations. Reduction in aggressiveness were accompanied by volumetric reduction in brain areas associated with aggressive behaviour (express genes related to aggressive behaviour), and increases in regions related to somatosensation. These findings further elucidates the neurocircuitry of aggression and suggests novel neuromodulation targets.

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.
