Alcohol use disorders and ADHD

Despite a growing literature on the complex bidirectional relationship of ADHD and substance use, reviews specifically focusing on alcohol are scarce. ADHD and AUD show a significant genetic overlap, including genes involved in gluatamatergic and catecholaminergic neurotransmission. ADHD drives risky behavior and negative experiences throughout the lifespan that subsequently enhance a genetically increased risk for Alcohol Use Disorders (AUD). Impulsive decisions and a maladaptive reward system make individuals with ADHD vulnerable for alcohol use and up to 43 % develop an AUD; in adults with AUD, ADHD occurs in about 20 %, but is vastly under-recognized and under-treated. Thus, routine screening and treatment procedures need to be implemented in AUD treatment. Long-acting stimulants or non-stimulants can be used to treat ADHD in individuals with AUD. However, it is crucial to combine medical treatment for ADHD with pharmacotherapy and psychotherapy for AUD, and other comorbid disorders. Identification of individuals at risk for AUD, especially those with ADHD and conduct disorder or oppositional defiant disorder, is a key factor to prevent negative outcomes.

Automated summary

There is a significant genetic overlap between ADHD and Alcohol Use Disorders (AUD), with individuals with ADHD being more vulnerable to alcohol use and having a higher prevalence of AUD. Screening and treating ADHD in AUD treatment, as well as combining medical treatment for ADHD with pharmacotherapy and psychotherapy for AUD, are crucial for effective management. Identification of individuals at risk for AUD, especially those with ADHD and conduct disorder or oppositional defiant disorder, is essential for preventing negative outcomes.
