Binge drinking (BD) is the most common problematic drinking pattern during adolescence and youth. At the same time, it is a period marked by profound structural and functional brain changes, which may be affected by heavy alcohol consumption. In recent years, a considerable number of studies that attempt to characterize the effects of BD on the brain has been published. However, to date there is not any critical review in Spanish language on neurostructural, neurophysiological and cognitive consequences that may result from the maintenance of a BD pattern of alcohol consumption during adolescence and youth. The purpose of this review is to critically summarize the main research results on the effects of BD on the brain. To this end, a literature search in databases Web of Knowledge, PubMed and PsycINFO for the period 2000-2013 was performed. In general, studies agree that BD is associated with 1) lower performance on tasks assessing cognitive processes such as attention, memory and executive functions, 2) structural changes (in white matter and gray matter) in different brain regions and 3) neurophysiological abnormalities (hyper/hypoactivation) linked to different cognitive processes. These results, although still need to be contrasted, warn about important consequences that could result from the persistence of BD on a young and still maturing brain.
