Understanding the Link between ADHD and Substance Use Disorders

TLDRADHD is a disease of executive dysfunction, characterized by deficient behavioral inhibition, altered sensitivity to reinforcement, and impulsivity. These neuroscientific vulnerabilities make individuals with ADHD more prone to substance use disorders. Stimulant medication, which boosts dopamine activity in the prefrontal cortex, can temporarily alleviate ADHD symptoms. However, chronic drug use can lead to a decrease in dopamine activity and worsen ADHD. The D2 receptor, responsible for increasing the dopamine signal, may be lower in individuals who are abstinent from substance use.
