Brain zaps and brain games: new hope for opioid recovery?
NCT ID NCT07158853
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 4 times
Summary
This study tests whether adding a gentle brain stimulation technique (tDCS) along with computer-based thinking exercises can improve brain function and self-control in people being treated for opioid use disorder with buprenorphine. About 160 adults will either get real or fake stimulation to see if it helps their thinking and brain connections. The goal is to find a better way to support recovery, not to cure the condition.
