Impulsivity in Alcohol Use Disorder: A Multidimensional Perspective

Impulsivity is a key construct in the development, maintenance, and escalation of drinking behavior, ultimately leading to alcohol use disorder. Because impulsivity is a multidimensional construct and has many ways of measurement, it is difficult to reach a clear consideration of its association with alcohol. Assessment of impulsive personality traits, impulsive choice, and impulsive action simultaneously in studies is recommended. On the other hand, impulsivity seems to be both a determinant and a consequence of alcohol use disorder. Short- and long-term effects of alcohol are also associated with increased impulsivity, further enhancing the risk for continued alcohol consumption and thus maintaining a cycle of use. Impulsivity is also considered an endophenotype, a heritable trait that can predict the likelihood of developing alcohol use disorder. Impulsivity can be a target for interventions, including cognitive-behavioral therapy and mindfulness-based approaches, to improve impulse control and reduce relapse rates. A comprehensive understanding of its role in alcohol use disorder seems to be important for the development of effective treatment and prevention strategies.
