This lesson dives into the neuroscience and treatment of addiction, explaining why chronic substance use physically alters the prefrontal cortex — the brain's center for decision-making and judgment — making relapse a symptom of the disease rather than a moral failing. Drawing from Section 16.4 of Psychology 2e, the discussion covers everything from relapse rates and treatment timelines to family-based teen interventions and comorbid psychiatric disorders. Whether you're studying abnormal psychology or just want to understand how addiction really works, this video breaks it all down clearly. In this video: • How chronic substance use permanently rewires the prefrontal cortex, driving compulsive drug-seeking behavior • Why 40–60% of individuals relapse and why relapse is viewed as a symptom of a chronic disease • The evidence-based finding that at least 3 months of treatment is needed to achieve a positive outcome • Why effective treatment must be holistic, addressing stress management, communication, legal concerns, and more • How drug use peaks in the 18–25 age group and why teen treatment requires whole-family participation • The MICA category — mentally ill and chemically addicted — and why simultaneous treatment of comorbid disorders is essential • How bupropion, an antidepressant, can reduce methamphetamine cravings, and why substance abuse costs the U.S. over $600 billion annually #OpenStax #Psychology #Addiction #AbnormalPsychology #SubstanceAbuse OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
