Alcohol use disorder is a brain disease that can be modeled by an imbalance between three cerebral and cognitive systems. The reflective system, underpinned by the frontal cortex and corresponding to the executive functions, would be involved in the control of alcohol consumption. The impulsive system, underpinned by the amygdala-striatal complex, would favor automatic and impulsive drinking behaviors. A regulatory system, driven by insula and involved in the integration of proprioceptive perceptions in situations of deprivation or stress, would aggravate the imbalance between the two first systems. This model provides a new framework for understanding alcohol use disorder and new perspectives on therapeutic targets that could be included into integrated and customized treatments.
