Co-Occurring Psychiatric and Substance Use Disorders (2025-2026 Recording)-Co-Occurring Psychiatric and Substance Use Disorders Recording

Video Transcription

Video Summary

The session focused on co-occurring psychiatric and substance use disorders, emphasizing that these conditions are common, overlapping, and often mutually reinforcing rather than exceptions. Dr. Sheila Specker reviewed terminology, epidemiology, diagnostic challenges, and treatment principles. She highlighted that lifetime overlap is high: about half of people with a substance use disorder will have a mental health disorder, and vice versa. Bipolar disorder was noted as having especially high rates of substance use co-occurrence, with worse outcomes including poorer medication response, more hospitalizations, more suicidality, and more relapse.<br /><br />A key theme was careful chronological history: clinicians should determine which symptoms came first, whether symptoms persist during abstinence, and whether they fit substance-induced criteria. She reviewed how intoxication and withdrawal can mimic mood, anxiety, psychotic, or other psychiatric syndromes, and stressed that treatment should address both disorders when present. Integrated care, psychosocial support, and medication choices tailored to diagnosis, adherence, toxicity, and side effects were emphasized.<br /><br />Dr. Sarah Usher then presented a detailed case of a 23-year-old woman with depression, anxiety, PTSD, opioid/cannabis/stimulant use disorders, and later-confirmed bipolar I disorder. Her course illustrated diagnostic uncertainty, substance-related destabilization, repeated relapses, medication nonadherence, suicidality, and barriers to treatment. The case reinforced the importance of ongoing reassessment, integrated treatment, and considering long-acting injectable options for both psychiatric and substance use disorders.
