Brain training targets impulse control to fight OCD and related disorders
NCT ID NCT05377125
First seen Jul 09, 2026 · Last updated Aug 11, 2026 · Updated 3 times
Summary
This study tests whether a computerized training program designed to improve response inhibition — the ability to stop an automatic action — can reduce symptoms in people with obsessive-compulsive disorder, trichotillomania (hair-pulling), or skin-picking disorder. Participants are randomly assigned to receive either the active training or a placebo version over 8 to 16 sessions. The researchers measure changes in symptom severity and brain activity using MRI scans to see if the training works and how.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- computerized cognitive training
- What this could lead to
- If effective, this training could offer a new, non-drug treatment option for people with obsessive-compulsive and related disorders.
- What could go wrong
- This is an early-stage trial with a modest number of participants. The training may not produce lasting symptom improvement, and results may not apply to everyone.
