# Treatment of alcohol use disorder via magnetic resonance-guided focused ultrasound ablation surgery

## TL;DR

A noninvasive surgery using focused ultrasound reduced a man's severe alcohol addiction and improved his mental health with no major side effects.

## Contribution

This is the first reported case of MRgFUS targeting the nucleus accumbens for treating alcohol use disorder.

## Key findings

- Bilateral nucleus accumbens MRgFUS reduced alcohol craving from 6 to 0 in a 54-year-old man with AUD.
- The patient remained abstinent for 12 months post-treatment with improvements in depression, anxiety, and quality of life.
- No serious adverse effects were observed during the 12-month follow-up period.

## Abstract

Alcohol use disorder (AUD) is a problematic pattern of drinking that can cause significant impairment or distress. Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel noninvasive technique permitting incision-less ablative treatment, which may be effective for AUD.

We present the case of a 54-year-old man diagnosed with AUD for 30 years. After bilateral nucleus accumbens (NAc) MRgFUS, his craving for alcohol decreased markedly from 6 to 0, and he remained abstinent throughout the follow-up (12 months). Moreover, psychiatric and neuropsychological assessments showed improvements in depression, anxiety, sleep, and quality of life. Besides, he did not have any serious adverse effects during the whole follow-up period.

This case report suggests the feasibility and potential of NAc ablation via MRgFUS in treating severe AUD. Subsequent multi-sample double-blind controlled trials need to be further studied. The effect of MRgFUS on the use disorders of other substances also requires further research.
