Deep TMS Neuromodulation of Neural Circuits Associated With Stimulant Use Disorder
Stanford University
Summary
This study aims to evaluate the efficacy of deep transcranial magnetic stimulation (dTMS) as a treatment for Veterans with a methamphetamine use disorder (MUD).
Description
To date, TMS has emerged as a promising treatment avenue for addiction and is being tested in clinical trials with some encouraging results. A recent systematic review and meta-analysis highlights that 7/8 (87.5%) studies using TMS for MUD or 38/50 (88%) in addiction more broadly have targeted the left DLPFC alone. While this strategy has been useful in reducing craving, treated individuals resume use shortly after treatment at similar rates to those receiving sham. Here, utilizing a data-driven and innovative approach, the investigators aim to modulate target brain function that has been show…

Interventions
- DeviceDeep Transcranial Magnetic Stimulation (dTMS) H4 coil - Active
The study will utilize the H4 coil to administer active Deep Transcranial Magnetic Stimulation (dTMS) to the bilateral insula, a core salience network node.
- DeviceDeep Transcranial Magnetic Stimulation (dTMS) H4 coil - Sham
The study will utilize an identical protocol using the H4 coil to administer a sham condition.
