Key result
Neuropsychological performance does not differ between early and late abstinence, but higher consumption predicts worse scores.
Observational (n=79)
p-value: p=not significant
Recent and chronic alcohol consumption interact nonlinearly with age and education to predict neuropsychological performance in alcoholic men.
The authors examined performances on 24 commonly used clinical neuropsychological tests for drug-free alcoholic men in their mid to late 30s either within 2--6 days of their last drink (N = 59) or between 14 and 31 days after their last drink (N = 20). Although mean scores were indicative of impairment on approximately half of the tests, no statistically significant overall difference in performance between individuals tested at these two time periods was observed. Recent and chronic alcohol consumption variables were found to interact with each other and with age and education in a nonlinear fashion in predicting neuropsychological performance. Increased consumption predicted decreased performance even on tests whose mean scores were in the normal range.

Eckardt et al. (1980) conducted an observational in Alcoholism (n=79). Abstinence of 2-6 days vs. Abstinence of 14-31 days was evaluated on Performance on 24 clinical neuropsychological tests (p=not significant). Neuropsychological performance did not significantly differ between alcoholic men tested 2-6 days versus 14-31 days after their last drink, though increased consumption predicted worse performance.
