New Brain Stimulation Method Offers Rapid Relief for Depression
A recent study has revealed a promising new approach for alleviating moderate to severe depression, utilizing a technique known as high-definition transcranial direct current stimulation (HD-tDCS). Researchers from the University of California, Los Angeles (UCLA) found that this noninvasive method may offer faster relief compared to traditional treatments.
The trial involved 71 adults diagnosed with major depression. Participants were randomly assigned to receive either active HD-tDCS or a sham treatment, with sessions lasting 20 minutes daily over a span of 12 working days. The findings, published on March 15, 2025, in JAMA Network Open, indicated that those receiving the actual treatment exhibited a more significant reduction in depression scores than those in the control group.
On average, participants in the active treatment group saw their depression scores decrease by nearly eight points, while the sham group experienced a reduction of about six points. Notably, the HD-tDCS group also had a higher rate of remission, with 39.5% of patients reporting very low symptoms compared to 13.3% in the sham group.
Effective Treatment with Minimal Side Effects
Lead author Mayank Jog, an assistant professor of neurology at UCLA, emphasized the significance of targeting specific brain regions linked to depression. “By honing in on the precise brain regions affected by depression, we’ve shown that stimulation can significantly improve mood and daily functioning,” he stated in a news release.
The therapy proved to be safe and well-tolerated, with participants reporting only mild side effects, such as skin redness or a burning sensation. Impressively, mood improvements were observed after just six days of treatment, a timeline that contrasts sharply with many medications and talk therapies, which often take weeks to show effects.
Potential for Broader Applications
The researchers noted that there is potential for HD-tDCS to also benefit individuals suffering from anxiety disorders, although further studies are necessary to explore this possibility. While the results are encouraging, experts caution that longer-term studies with maintenance treatments are essential to determine how long the benefits of this therapy last.

This innovative approach may represent a promising advancement in the field of mental health treatment, providing hope for many who struggle with depression.
