Официальное название
Investigation of the Relationship Between Electrophysiological Biomarkers and Treatment Response in Patients Diagnosed With Obsessive-Compulsive Disorder Undergoing Transcranial Magnetic Stimulation Therapy
Обзор
Purpose: This study aims to evaluate the effectiveness of an accelerated intermittent Theta Burst Stimulation (iTBS) protocol-a non-invasive brain stimulation technique-targeted at the dorsomedial prefrontal cortex (dmPFC) and anterior cingulate cortex (ACC) in patients with treatment-resistant Obsessive-Compulsive Disorder (OCD). Additionally, the study seeks to identify electrophysiological biomarkers (such as EEG microstates and heart rate variability) that may predict which patients are most likely to benefit from the treatment. Methodology: The study will include 30 patients aged 18-65 diagnosed with OCD according to DSM-5 criteria who have not responded sufficiently to standard treatments. Participants will undergo an intensive 7-day treatment program consisting of 4 iTBS sessions per day (totaling 28 sessions). Clinical symptoms will be assessed before and after the treatment using standardized scales, including the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Hamilton Depression Rating Scale (HAM-D), and Hamilton Anxiety Rating Scale (HAM-A). Resting-state EEG measurements and heart rate data will be recorded during and after the sessions to analyze physiological changes. Goal: The findings are expected to contribute to the development of personalized neuromodulation protocols and help identify predictors of treatment response for OCD patients.
Вмешательства
- Устройство iTBS TMS
Accelerated intermittent Theta Burst Stimulation (iTBS) will be delivered using a MagVenture MagPro R30 stimulator with a Cool D-B80 double cone coil. The stimulation is targeted at the dorsomedial prefrontal cortex (dmPFC) and anterior cingulate cortex (ACC), specifically 25.8% anterior of the nasion-inion distance. The treatment will be applied at 100% of the motor threshold, which is determined via the Extensor Hallucis Longus muscle. The protocol consists of an intensive 7-day program with
Первичные конечные точки
- Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) Total Score [Срок оценки: Change from baseline in clinical scales at the end of the 7-day treatment and at follow-up points (1, 3, and 6 months post-treatment)"]
Вторичные конечные точки (2)
- EEG Microstate Analysis Parameters [Срок оценки: Baseline, Day 7 (after treatment)]
- Frontal-Vagal Activity via Heart Rate Deceleration (HRD) [Срок оценки: During each of the 28 iTBS sessions over the 7-day treatment period]
