Brain zaps timed to brain waves may boost addiction recovery

This study tests if timing magnetic brain stimulation to match a person's own brain waves can improve treatment for stimulant use disorder. Researchers will enroll 50 adults who are currently in treatment and have been drug-free for at least 2 weeks. Participants will get an MRI and then receive brain stimulation either randomly or timed to the peak or trough of their brain's theta waves. The goal is to see which timing method produces the best brain and behavior changes.
