What this trial studies

This randomized controlled trial investigates the effectiveness of transcranial alternating current stimulation (tACS) in patients aged 18 to 55 with treatment-resistant depression (TRD) and elevated inflammatory markers. Over a 12-week period, participants will receive either active tACS or sham stimulation, with assessments of depressive symptoms and biological markers conducted at baseline, during, and after the intervention. The study aims to clarify the impact of tACS on depressive symptoms and explore underlying mechanisms of action related to inflammation. A total of 52 patients will be enrolled and monitored throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 55 diagnosed with treatment-resistant depression and exhibiting high levels of inflammation.

Not a fit: Patients with a history of seizures, significant suicidal risk, or those who have undergone electroconvulsive therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a novel therapeutic option for patients suffering from treatment-resistant depression linked to high inflammatory activity.

How similar studies have performed: While the approach of using tACS for depression is emerging, similar studies have shown promising results, indicating potential for success.
