Correlation of impulsivity and alcohol consumption disorder: the puzzle of a neural circuit

The disorder by alcohol consumption is a disease that integrates the dependence of alcohol and the excessive use of this with negative cognitive repercussions. For many years the etiology of this dependence has been studied, impulsivity being the most distinctive feature. It has been reported that this behavioral characteristic not only influences to alcohol consumption but can be inverse. Because of this, present review details how these two factors are interrelated, but also describes how they are involved in alterations on specialized structures of the brain, and also analyzed molecular aspects, as well as genetic or epigenetic bases that underlined on this circuit.
