Alcohol use disorders serve as a significant and modifiable risk factor for the development of dementia, underscoring the urgent need for proactive clinical and public health interventions. Emerging research suggests that the relationship between alcohol consumption and cognitive health is nuanced, with studies indicating that the lowest risk for cognitive dysfunction and dementia is associated with low-level intake, specifically around 30 g and 15 g of alcohol per day, respectively. To effectively mitigate the long-term impact of alcohol-related cognitive decline, healthcare systems must prioritise the integration of routine screening for heavy drinking into standard medical care, ensuring timely access to intervention and treatment. Beyond individual clinical efforts, the implementation of broader population-level alcohol policies remains a vital strategy to reduce excessive consumption and ultimately lower the societal burden of alcohol-related dementia.
