Alcohol is a pleiotropic substance with multiple effects. Alcohol is one of the most frequently used drugs in the world. Alcohol misuse may affect all systems of an organism, but the nervous system remains one of the most vulnerable. A wide range of literature data suggests that the nervous system is one of the most susceptible systems to alcohol misuse. However, it is not exactly clear how alcohol affects different aspects of brain functions in various groups of people. The paucity of information on the mechanisms and processes of how this psychotic substance affects cognition is one contributing factor. Cognitive functions represent an integral part of higher integrative brain functions that enable an organism to carry out higher-level activities.
Although there have been reports on some positive effects of alcohol, other reports show huge negative effects. These controversies have lingered for decades. While some authors have described these controversies in the light of individual, population, gender, genetic, age, and physiological differences, alternatively there could be more complex interactions among these indices such as intra-cellular, intra-genetic. We hope to gather articles from a wide range of authors throughout the world as regards to the effects of alcohol use on cognitive functions and the recent developments in this area of research.
