Alcohol consumption in mild cognitive impairment and dementia: harmful or neuroprotective
International Journal of Geriatric Psychiatry, 03/20/2012
Panza F et al. – Protective effects of moderate alcohol consumption against cognitive decline are suggested to be more likely in the absence of the Alzheimer's disease–associated apolipoprotein E ε4 allele and where wine is the beverage. At present, there is no indication that light–to–moderate alcohol drinking would be harmful to cognition and dementia, and attempts to define what might be deemed beneficial levels of alcohol intake in terms of cognitive performance would be highly problematic and contentious.
