Trigeminal nerve stimulation for the treatment of major depressive disorder and obsessive-compulsive disorder: a case study
Bibliographic record
Abstract
Neuromodulation techniques have been proposed as add-on strategies for modulating brain areas involved in obsessive-compulsive disorder symptoms. Trigeminal nerve stimulation is a novel neuromodulation technique, which, to date, has not yet been explored for obsessive-compulsive disorder treatment. In this report, we describe a 52-year-old female patient suffering from major depressive disorderand obsessive-compulsive disorder for 18 and 32 years, respectively and successfully undergoing a trigeminal nerve stimulation intervention protocol (10 consecutive daily trigeminal nerve stimulation sessions), with amelioration of symptoms. Cognitive function was not obviously altered as assessed by the Montreal Cognitive Assessment. Major depressive disorder and obsessive-compulsive disorder symptoms assessed using the Yale-Brown Obsessive-Compulsive Scale and the 17-item Hamilton Depression Rating Scale substantially improved after the 10-day treatment course and remained stable after 1-month follow-up (30 days after final trigeminal nerve stimulation). The patient reported significant global clinical gains and mild diurnal sleepiness without severe adverse effects. Trigeminal nerve stimulation has been studied for the treatment of various neuropsychiatric disorders that share common functional alterations at the frontal cortex and subcortical areas, usually altered in obsessive-compulsive disorder. We present the first case report on trigeminal nerve stimulation for co-morbid obsessive-compulsive disorder and major depressive disorder. These encouraging results should be seen as hypothesis-driving for further controlled randomized trials exploring the impact of trigeminal nerve stimulation in the treatment of obsessive-compulsive disorder.doi: 10.4103/2542-3932.198962How to cite this article: Trevizol AP, Sato IA, Cordeiro Q (2017) Trigeminal nerve stimulation for the treatment of major depressive disorder and obsessive-compulsive disorder: a case study.

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.
