Summary

Transcranial Magnetic Stimulation (TMS) therapy is an approved and effective treatment option for treatment-resistant depression (TRD). This study aims to identify biomarkers that predict TMS treatment response in TRD, provide insights into the neurobiological mechanisms underlying TMS efficacy, and contribute to personalized treatment strategies. By establishing proteomic and metabolomic signatures, this research seeks to enhance clinical decision-making, reduce healthcare costs, and improve patient outcomes in TRD. The findings will align with the precision medicine movement in psychiatry, advancing biomarker-driven therapeutic approaches for treatment-resistant depression.

Conditions

  • Major Depression Disorder

Interventions

DEVICE

TMS

Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation technique approved for the treatment of major depressive disorder (MDD), particularly in individuals with treatment-resistant depression (TRD). TMS targets the left dorsolateral prefrontal cortex (DLPFC), a brain region often underactive in depression, and modulates neural activity through magnetic pulses. This study aims to evaluate the effects of TMS on plasma proteomic and metabolomic profiles in patients with TRD. Participants will undergo 20 sessions of intermittent theta burst stimulation (iTBS) over four weeks. Blood samples will be collected before and after treatment to identify molecular changes associated with clinical response. Healthy controls will provide single-time-point blood samples for baseline comparison. Findings may support the development of biomarker-based strategies for personalized treatment in psychiatry.
