What this trial studies

This project aims to evaluate the effectiveness of heart rate variability (HRV)-guided transcranial direct current stimulation (tDCS) in individuals with mild to moderate depression. A total of 100 participants will be recruited to undergo a double-blinded, parallel-arm, sham-controlled intervention at home, where they will receive either active or sham tDCS for 30 minutes over 10 days. The study will collect heart rate data during sessions to identify potential markers of response to the treatment. Participants will be randomized in a 2:1 ratio to receive either the active or sham stimulation.

Who should consider this trial

Good fit: Ideal candidates for this study are adults with mild to moderate depression as indicated by specific diagnostic criteria.

Not a fit: Patients with severe psychiatric disorders, significant medical conditions, or high suicidality risk may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel, non-invasive treatment option for individuals suffering from depression.

How similar studies have performed: While the use of tDCS has been explored in other studies, the specific HRV-guided approach is relatively novel and has not been extensively tested.
