Transcranial magnetic stimulation reduces alcohol craving in patients with alcohol use disorder
A meta-analysis of 19 RCTs involving 942 patients with AUD found that TMS significantly reduced alcohol craving compared to sham stimulation. Subgroup analysis showed significant effects with cTBS, 10 or 15 sessions, 10 Hz frequency, and follow-up ≤1 month or ≥3 months. TMS also improved abstinence days, reduced alcohol intake, alleviated depressive symptoms, and enhanced cognitive function.

The Claim
Transcranial magnetic stimulation reduces alcohol craving in patients with alcohol use disorder
This conclusion is most relevant to: Patients with alcohol use disorder (AUD) from 19 RCTs (n=942).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸The Effects of Transcranial Magnetic Stimulation on Alcohol Craving, Efficacy, Emotion, and Cognitive Function in Patients With Alcohol Use Disorders: A Systematic Review and Meta-Analysis of Randomized Controlled Trial. (Brain and behavior, 2026) —
How It Works
The proposed biological pathway:
- ▸TMS modulates cortical excitability in brain regions associated with craving
- ▸Stimulation of prefrontal cortex reduces neural activity linked to alcohol cues
- ▸Alters neurotransmitter release (e.g., dopamine) affecting reward pathways
- ▸Result: Reduced alcohol craving and improved abstinence
Who Might Benefit
Evidence fit by population:
- ▸Patients with alcohol use disorder (AUD) from 19 RCTs (n=942)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸High heterogeneity in alcohol craving outcomes, possibly due to disease type
- ▸Limited number of large-sample, multi-center, double-blind RCTs available
- ▸Results interpreted with caution due to heterogeneity
Frequently Asked Questions
What is the main finding of this study?▼
TMS significantly reduces alcohol craving in AUD patients and improves abstinence days, alcohol intake, depression, and cognitive function.
How many patients were included in the meta-analysis?▼
942 patients with alcohol use disorder from 19 randomized controlled trials.
What TMS parameters were most effective?▼
Continuous theta burst stimulation (cTBS), 10 or 15 sessions, 10 Hz frequency, with follow-up ≤1 month or ≥3 months.
What are the limitations of this evidence?▼
High heterogeneity in craving outcomes and a need for more large-scale, double-blind RCTs to confirm results.
