Moderate Drinking of Alcohol Improves Later Cognition

A recently reported 18-year study of Japanese American men found "a positive association between moderate alcohol intake among middle-aged men and subsequent cognitive performance in later life." Moderate drinkers scored significantly higher on the Cognitive Abilities Screening Instrument (CASI), which includes tests of attention, concentration, orientation, memory, and language.

Both nondrivers and heavy drivers had the lowest CASI scores.
