About this trial

This study aims to explore how repetitive transcranial magnetic stimulation (rTMS), a treatment for depression, affects brain function. Depression disrupts the brain's complex network or regions that regulate cognition, emotion, and behavior. rTMS targets these disruptions to restore network function. To measure these effects, researchers will use dry quantitative EEG (qEEG), a new technology that records brain electrical activity quickly (15 minutes compared to 1 hour for traditional EEG) without the need for gel or lengthy electrode setups. This study will evaluate a novel qEEG activity developed by iMediSync (Republic of South Korea) in patients treated with neuromodulation for depression before, during, and up to 12 months after treatment to see if changes in brain activity to identify patterns associated with symptomatic improvement and relapse risk. Findings could help personalize depression treatments by predicting patient outcomes and optimizing care.
