A recent study explored the association between alcohol consumption and dementia risk in current drinkers through linear and non-linear Mendelian randomization analysis. The findings challenge previous beliefs by suggesting that as predicted alcohol consumption increases based on genetic factors, so does the risk of developing dementia. While past studies have shown a potential protective effect of light-to-moderate drinking on dementia risk, this research indicates a linear relationship where higher alcohol intake increases the likelihood of dementia. The study used data from over 300,000 participants and highlighted the need for prevention strategies due to the projected rise in global dementia cases.
