At-home brain stimulation could be promising depression treatment
A clinical trial with 174 patients suggests at-home brain stimulation may effectively treat depression, showing significant symptom improvement. However, concerns about trial design and demographic diversity limit generalizability.

A recent clinical trial indicates that at-home brain stimulation may serve as a viable treatment for depression. The study involved 174 patients experiencing moderate depression, who were divided into two groups: one used a headset delivering weak electric currents (transcranial direct current stimulation, or tDCS), while the other used a placebo device. Over ten weeks, the active treatment group showed a greater improvement in depressive symptoms, with 45% achieving clinical remission compared to 22% in the control group. Despite these promising results, experts have raised concerns about the trial's design, including potential biases due to patients guessing their treatment status and the limited demographic diversity of participants. The study primarily included white individuals and excluded those with severe depression, which may affect the generalizability of the findings. Nevertheless, the trial's authors believe that at-home tDCS could enhance access to effective mental health care, especially for patients who do not respond to traditional treatments.
- At-home brain stimulation shows potential as a first-line treatment for depression.
- The trial involved 174 patients, with significant improvements noted in the active treatment group.
- Concerns exist regarding the trial's design and demographic limitations.
- The study highlights the need for alternative therapies for patients unresponsive to conventional treatments.
- Experts emphasize the importance of improving access to mental health care.
