MedPage Today (9/23, George) reports, “Drinking any amount of alcohol increased dementia risk, data from a combined observational and genetic study suggested.” Researchers observed that “light alcohol consumption was associated with low dementia risk in observational analyses, and genetic analyses showed a monotonic increasing dementia risk with higher alcohol intake.” Furthermore, “Mendelian randomization suggested a causal role of alcohol consumption in increasing dementia risk with no evidence supporting a protective effect at any consumption level.” Overall, the study authors concluded the results “challenge the notion that low levels of alcohol are neuroprotective.” The study was published in BMJ Evidence-Based Medicine.
