Electrophysiological Biomarkers and Treatment Response to Accelerated Transcranial Magnetic Stimulation in Patients With Obsessive-Compulsive Disorder

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.

Clinical Efficacy of Intermittent Theta Burst Transcranial Magnetic Stimulation With Different Modes on Parkinson's Disease

TMS regulates cortical excitability through electromagnetic induction, with low-frequency stimulation suppressing and high-frequency stimulation enhancing excitability. Building on theta-gamma coupling, iTBS induces broader improvements in functional brain connectivity within a shorter stimulation period, particularly by significantly reducing abnormal variability in the prefrontal and parietal regions, demonstrating superior neuromodulatory efficiency and network remodeling capacity. This study aims to compare the symptomatic effects of different iTBS protocols on Parkinson's disease, optimize stimulation parameters, and evaluate safety, while also analyzing the time-dependent trends of therapeutic efficacy through 1- and 3-month follow-ups.

Deep Versus Standard Prolonged Intermittent Theta Burst Stimulation for Depression

This study compares two types of non-invasive brain stimulation to treat major depression in patients who have not found relief from at least one antidepressant medication. The study will use a specific type of brain stimulation called prolonged intermittent Theta Burst Stimulation (piTBS). The standard way to use piTBS for depression is to target an area on the side of the head called the dorsolateral prefrontal cortex (DLPFC). This study will compare this standard piTBS method with a newer approach, deep piTBS, which targets a different, deeper area in the middle of the brain called the anterior cingulate cortex (ACC). Participants will be randomly assigned to one of two groups. One group will receive the deep piTBS treatment, and the other will receive the standard piTBS treatment. Both treatments are given once a day, five days a week, for four weeks. The study aims to find out if the deep piTBS approach is more effective at reducing symptoms of depression than the standard approach. Researchers will also look at effects on anxiety and other related symptoms.

Comparison of the Efficacy of Accelerated Intermittent Theta Burst Stimulation and Accelerated Continuous Theta Burst Stimulation in Patients With Treatment-Resistant Depression

In recent years, research on the effectiveness of transcranial magnetic stimulation (TMS) in patients with treatment-resistant depression (RTD) has been steadily increasing. The aim of this study was to examine the effectiveness of accelerated unilateral application of two different forms of theta burst stimulation (TBU), a variation of repetitive TMU (rTMS)-intermittent TBU (iTBU) and continuous TBU (cTBU)-in TDD patients. The study aimed to compare the advantages of iTBU and cTBU protocols on depression, suicidal thoughts, anxiety levels, sleep disturbances, cognitive performance, and overall functioning following a two-week intensive treatment period and a 12-week follow-up period.

Effects of ITBS Combined with NMES on Dysphagia After Stroke

In recent years, research on intermittent Theta Burst Stimulation (iTBS), as a special high-frequency （repetitive transcranial magnetic stimulation，rTMS） stimulation paradigm, has focused on exploring the effects in healthy people. Based on previous studies, it is believed that the central magnetic stimulation combined with peripheral electrical stimulation based on the "central-peripheral-central" closed-loop rehabilitation concept has the best effect, but there are few clinical studies on the efficacy and mechanism of iTBS combined treatment of dysphagia after stroke, and the selection of the optimal stimulation scheme and target has not yet been determined, therefore, this study aims to observe the efficacy and mechanism of implementation of iTBS combined with neuromuscular electrical stimulation (NMES) on with patients with dysphagia (PSD) .
