Abstract

fetched live from OpenAlex

Introduction Repetitive Transcranial Magnetic Stimulation (rTMS) is a novel neuromodulation treatment investigated for multiple psychiatric conditions and approved primarily for treatment-resistant depression (TRD) [1, 2]. There is a perceived potential for other clinical conditions, primarily other mood and anxiety disorders [2]. We have been using rTMS for treatment of patients with TRD of mixed etiology and multiple comorbidities. Objectives To evaluate the effectiveness and feasibility of rTMS in complex clinical populations. Methods Observational study. Quick Inventory of Depressive Symptomatology (QIDS). Generalized Anxiety Disorder Questionnaire (GAD-7). Descriptive statistics. Results We have treated 90 patients, 46 women (51.1%) and 44 men (48.9%), with average age of 42.5±16.9 years. Vast majority (88.9%) of patients had a primary diagnosis of major depressive disorder, 8.9% had bipolar depression, and two patients had primary anxiety disorders. The standard questionnaires were used to quantify the severity of depressive symptoms (QIDS) and anxiety (GAD-7). The average baseline scores for depression and anxiety were 16.6±4.9 and 12.7±5.5, respectively. The patients received an average of 24.0±7.0 treatments. Almost all patients received the full course of 20-30 treatments as planned. The average end-of-treatment (EoT) scores for severity of depressive symptoms and anxiety were 10.5±6.1 and 8.4±5.8, respectively. The rates of improvement and complete resolution of depressive symptoms were 64.4% and 28.7%, respectively. The rates of improvement and complete resolution of anxiety symptoms were 53.5% and 29.6%, respectively. There was a significant difference between the bipolar and major depression in terms of baseline depressive symptoms severity and improvement rates, but there was no difference in respect to anxiety symptoms (see Figure 1). Image 1: Conclusions rTMS provides significant improvement and recovery rates in complex clinical populations and is well-tolerated. We recommend wider implementation of rTMS for treatment of mood and anxiety disorders. References 1. Samokhvalov AV, Weber M.

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.
