First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 1 trial tested transcranial direct current stimulation (tDCS) in 42 adults with obsessive-compulsive disorder (OCD). Participants received 10 sessions of either low-dose, higher-dose, or fake (sham) electrical stimulation over five days. The goal was to see if tDCS could improve OCD symptoms, quality of life, depression, and thinking skills. Results are not yet reported, but the study aims to find a safe, non-drug option for managing OCD.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
transcranial direct current stimulation (tDCS)
What this could lead to
If it works, this could point toward a non-invasive brain stimulation treatment to reduce OCD symptoms and improve daily functioning.
What could go wrong
This is a small, early-phase trial with only 42 participants, so results may not apply widely. The effects of tDCS can vary, and the study compares different doses, so the best approach is still uncertain.
