Neuroimaging in alcohol-use disorders: clinical implications and future directions

Abstract

Advances in clinical research have led to significant alterations in diagnostic criteria for alcohol-use disorders (AUD). Neuroimaging techniques are now being called upon to shed light on the validity and clinical utility of diagnostic criteria. For example, craving has recently been added to the diagnostic criteria of AUD based mainly on neurobiological research. In addition to understanding the nuances of the craving process, neuroimaging techniques are helping determine the biological factors that contribute to the onset and maintenance of the disorder and offer insight into the mechanisms underlying treatment. The purpose of this review is to provide a clinically relevant summary of the neuroimaging research that has impacted our understanding of the etiology, treatment and recovery in AUD.
