Magnetic pulses to the brain target gambling cravings
NCT ID NCT07828782
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers at Sveti Ivan Psychiatric Hospital are testing whether high-frequency repetitive transcranial magnetic stimulation (rTMS) with the H7 coil reduces gambling disorder symptoms. The trial enrolls 60 men aged 18 to 64 who are starting treatment at a gambling disorder day hospital. Participants are randomly assigned to active rTMS or a sham treatment that feels similar but delivers no active magnetic stimulation, and neither they nor the assessors know which they receive. Everyone continues their usual care. Over six weeks, the team measures changes in gambling symptom severity, cravings, heart rate variability, and cost, and looks for personal or clinical traits that predict who responds.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation using the H7 coil
- What this could lead to
- If it works, deep brain stimulation with the H7 coil could offer a non-drug option for people whose gambling disorder has not responded to standard care.
- What could go wrong
- This is a small, six-week study of 60 men, so any benefit may be short-lived or may not apply to women or to people with other conditions. Brain stimulation can cause scalp discomfort, headache, or lightheadedness, and the sham comparison means some participants receive no active magnetic pulses.
