Scientists from the Research Society on Alcoholism reviewed 26 studies on alcohol-induced blackouts published in the past five years. The authors state that identifying the factors that contribute to and result from alcohol-induced blackouts is critical in developing effective prevention programmes.
The updated review (2010 to 2015) of clinical research focuses on alcohol-induced blackouts, outlines practical and clinical implications, and provides recommendations for future research.
Twenty-six studies reported on alcohol-induced blackouts. Fifteen studies examined prevalence and/or predictors of alcohol-induced blackouts. Six publications described the consequences of alcohol-induced blackouts, and 5 studies explored potential cognitive and neurobiological mechanisms underlying alcohol-induced blackouts. The authors conclude that recent research on alcohol-induced blackouts suggests that individual differences, not just alcohol consumption, increase the likelihood of experiencing an alcohol-induced blackout, and the consequences of alcohol-induced blackouts extend beyond the consequences related to the drinking episode to include psychiatric symptoms and neurobiological abnormalities.
Prospective studies and a standardised assessment of alcohol-induced blackouts are needed to fully characterise factors associated with alcohol-induced blackouts and to improve prevention strategies, the authors conclude.
