Brain training and drug combo aims to curb alcohol cravings
NCT ID NCT05042102
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a drug called donepezil, combined with cognitive training (brain exercises), can help people with alcohol use disorder drink less heavily. Researchers will compare this combo to a placebo in 160 adults aged 18-80. The goal is to see if the treatment reduces the number of heavy drinking days and improves thinking skills.

Inclusion criteria: 1. Males and females 18-80 years of age 2. Fluency in English and a 6th grade or higher reading level 3. Meets the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for a current alcohol use disorder (subjects should have a primary alcohol use disorder \[AUD\] diagnosis, but may have concurrent occasional use of other substances) 4. Last alcohol use and at least one heavy drinking day within the past 30 days 5. Willingness to attend follow-up assessments at 13 weeks 6. Willingness to submit to Urine Toxicology screenings Exclusion criteria: 1. Lifetime diagnosis of a psychotic disorder, not induced by drug use 2. Current treatment with opioids or benzodiazepines, which may affect new learning 3. Involvement in a legal case that may lead to incarceration during the study period 4. Residential plans that would interfere with participation 5. Medical illness that may significantly compromise cognition (e.g., Parkinson's, Alzheimer's, Huntington's chorea, moderate or greater TBI) 6. An uncorrected sensory impairment (hearing or sight) that would seriously interfere with cognitive training 7. Pre-morbid intelligence quotient (IQ) estimate below 70 8. Unstable housing or lack of commitment to staying within a geographic area that would make follow-up unlikely 9.
