Investigating the effects of theta burst stimulation on brain-derived neurotrophic factor levels in depression

Antidepressant Effect of Prolonged Intermittent Theta-burst Stimulation on Serum Brain-derived Neurotrophic Factor Levels of Patients With Depression: A Randomized, Double-Blind, Sham-Controlled Study

Not applicable Interventional Taipei City Hospital · NCT05854706

This study is testing if a new brain stimulation technique can increase a specific protein in people with major depression to see if it helps improve their mood.

What this trial studies

This clinical trial aims to explore the impact of theta burst stimulation (TBS) on serum brain-derived neurotrophic factor (BDNF) levels in individuals diagnosed with major depressive disorder (MDD). Participants will be randomly assigned to either an active TBS group or a sham group, with the study measuring BDNF levels before and after treatment. The trial consists of 10 sessions of TBS administered over two weeks, with assessments conducted at baseline, after two weeks of treatment, and at a two-week follow-up. The study seeks to clarify the relationship between TBS and BDNF, which may play a role in the antidepressant effects of brain stimulation therapies.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 to 65 who meet the DSM-5 criteria for major depressive disorder.

Not a fit: Patients with major psychiatric illnesses, unstable medical conditions, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel and rapid treatment option for patients with major depressive disorder by enhancing BDNF levels.

How similar studies have performed: While there is evidence supporting the efficacy of repetitive transcranial magnetic stimulation, the specific application of theta burst stimulation in this context is relatively novel and has not been extensively tested.
