Purpose of Review <p>This scoping review fills the gap in knowledge on the epidemiology, clinical presentation, modifiable risk factors, and treatment of alcohol-related dementia (ARD) by summarizing the literature on the relationship between alcohol use and dementia published from January 1, 2020 to September 30, 2024.</p> Recent Findings <p>Epidemiological data on the prevalence of ARD are insufficiently harmonized, so clear conclusions for ARD or AUD and dementia can not be drawn. Rigorous testing and validation of the diagnostic criteria for ARD is required. The main risk factor for the onset of all types of dementia, especially early onset dementia (EOD), is AUD. Globally, modifiable risk factors (including alcohol misuse and AUD) account for up to 45% of dementia cases. Antipsychotic use reduced the alcohol consumption and the mortality in patients with Wernicke-Korsakoff syndrome (WKS) or ARD, and thiamine shows promise in preventing dementia in individuals with AUD. Still, further research is needed on the epidemiology and clinical presentation of ARD.</p> Summary <p>Clinical evidence of detrimental impact of alcohol on the brain and overall health is corroborated by alcohol-related neurodegeneration and neuroimaging data. As alcohol use is a modifiable and preventable risk factor for the development of ARD, effective alcohol prevention measures should be part of alcohol policies, interventions, and treatment. Future research should use consortium data and improved methodological approaches employing Mendelian randomization to avoid methodological limitations of observational studies.</p>
