Summary
Routine screening for heavy drinking should become standard care for older adults, with the review calling alcohol use disorders a major modifiable driver of dementia risk.
Heavy alcohol use is tied to neurodegeneration directly and through falls, head injuries, hypertension, stroke and alcohol-drug interactions, making early detection and intervention critical in geriatric care.
The evidence on low-to-moderate drinking remains contested: some studies suggest the lowest dementia risk near 15 g a day, while newer genetic and large-scale analyses increasingly argue no safe level exists for brain health.
Reducing or stopping alcohol can improve cognition, physical and mental health, and healthcare costs; the paper says abstinence for at least 6 months can stabilize or improve cognitive function.
With global dementia prevalence projected to rise from 57.4 million in 2019 to 152.8 million by 2050, the authors also back broader alcohol policies, clinician training and age-tailored treatment access.
