Magnetic brain zaps could curb alcohol cravings, new study hopes
NCT ID NCT06648642
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a treatment called IR-TMS, which uses magnetic pulses to target specific brain areas, to see if it can help people with Alcohol Use Disorder drink less. About 150 adults who drink heavily will receive several sessions of this treatment, along with brain scans and blood tests. The goal is to reduce cravings and alcohol use, and to find a brain-based marker that predicts relapse.
