Brain zaps for opioid cravings? One-Person trial tests safety

This study tested whether deep brain stimulation (DBS) is safe and feasible for people with severe opioid use disorder that hasn't improved with other treatments. Only one person took part. The approach involved implanting electrodes in brain areas linked to reward and addiction, then comparing active stimulation to a sham (inactive) condition. The goal was to see if DBS could reduce opioid use and improve brain function, but results are very limited due to the tiny size.
