Continuous Theta Burst Stimulation for Generalized Anxiety Disorder

Краткое описание

This randomized, rater-blinded clinical trial evaluates the effectiveness, safety, and tolerability of continuous theta burst stimulation (cTBS) in adults with generalized anxiety disorder (GAD). Participants will be randomly assigned in a 1:1 ratio to receive cTBS targeting either the right posterior parietal cortex (R-PPC) or the right dorsolateral prefrontal cortex (R-DLPFC). Participants may be psychotropic-medication naïve or may continue stable psychotropic medication according to the protocol-defined medication stability criteria. The primary objective is to compare changes in anxiety symptom severity, measured using the Hamilton Anxiety Rating Scale (HAM-A), from baseline to the end-of-treatment assessment. Secondary and exploratory assessments include treatment response and remission, quality of life, sleep quality, cognitive function, safety and tolerability, resting electroencephalography (EEG), and transcranial magnetic stimulation combined with EEG (TMS-EEG).
