Could zapping the brain help older adults drink less and think sharper?
NCT ID NCT05896332
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 2 times
Summary
This early-phase study tests whether a type of brain stimulation called rTMS can help older adults (ages 60-85) who have both alcohol use disorder and mild cognitive impairment. Participants receive 50 sessions of stimulation over one week. Researchers will measure changes in thinking skills, drinking behavior, and brain connectivity. The goal is to see if this approach can safely address both problems at once.
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 (rTMS)
- What this could lead to
- If it works, this could point toward a non-drug treatment that helps older adults drink less and think more clearly.
- What could go wrong
- This is a very early, small phase 1 trial with only 35 people, so results may not apply widely. The treatment is intensive (50 sessions in one week) and may cause discomfort or side effects like headache or scalp pain.

Inclusion Criteria: * Age 60-85. * English as a first/primary language. * Current alcohol use disorder * Alcohol consumption of at least 4 heavy drinking days (defined as ≥ 4 drinks for women and ≥ 5 for men) per week during the 30-days prior to enrolling; * Meets actuarial neuropsychological criteria for MCI: ≥2 impaired scores within one cognitive domain, or ≥1 impaired scores in ≥3 domains, where an impaired score is defined as ≤16th percentile using demographically-corrected norms. * Not pregnant (will administer pregnancy test to confirm) * Functional visual and auditory acuity to complete all assessments. Exclusion Criteria: * Prior diagnosis of Dementia or Major Neurocognitive Disorder per NIA-AA or DSM-5 criteria, and TICS ≤ 22 suggestive of dementia. * Current substance use disorder other than AUD or nicotine use disorder, bipolar disorder, or schizophrenia spectrum or other psychotic disorder. * Daily/weekly anticholinergic or sedative use. Stimulants may be allowed pending investigator review. Cholinesterase inhibitors, NMDA receptor antagonists, and antidepressants are allowed if on a stable regimen of 4 weeks prior to enrollment. * History of significant or unstable condition/s that may impact cognition such as significant cardiac, cerebrovascular, or metabolic disease, developmental disorder, or other neurologic disease (e.g. movement disorder, moderate to severe brain injury, seizures). * MRI and TMS contraindications (e.g. implants, claustrophobia, conditions/treatments that lower seizure threshold, taking medications that have short half-lives, no identifiable motor threshold). * Enrolled in a clinical trial or has received an investigational medication or device in the last 30 days. * Pregnant (will administer pregnancy test to confirm)
