Abstract

fetched live from OpenAlex

BACKGROUND: Previous research suggests that repetitive transcranial magnetic stimulation (rTMS) applied to the temporoparietal cortex may have therapeutic benefits for patients with schizophrenia and treatment-resistant auditory hallucinations. We aimed to test this hypothesis in a randomized double-blind trial. METHODS: Thirty-three patients with treatment-resistant auditory hallucinations entered a randomized sham-controlled, double-blind trial. rTMS was applied for 10 consecutive weekdays, for 15 minutes at 1 Hz and 90% of the resting motor threshold. We assessed clinical symptoms and cognitive function. RESULTS: rTMS was safe with no adverse effects on memory and cognitive parameters assessed. Active treatment did not result in a greater therapeutic effect than sham on any measure except for the loudness of hallucinations where there was a significant reduction in the active versus the sham group over time. CONCLUSIONS: The study does not support the effectiveness of rTMS using the stimulation parameters provided. However, it does suggest that rTMS methods may have a therapeutic role and indicates the need for further exploration of alternative and more effective stimulation methods.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
