Abstinence, heavy drinking, binge drinking associated with increased risk of cognitive impairment

ScienceDaily (Jan. 11, 2011) ? Previous research regarding the association between alcohol consumption and dementia or cognitive impairment in later life suggests that mild to moderate alcohol consumption might be protective of dementia.
