Substance and Medication Induced Psychosis: Recognition and Management-Recording

Video Transcription

Video Summary

Dr. Hector Colombi-Vera, an addiction, sports, and adolescent psychiatrist, presented on substance and medication-induced psychosis. He provided a comprehensive overview of how substances and certain medications can lead to psychosis, distinguishing primary from secondary (substance-induced) psychosis. The presentation covered several key learning objectives, including defining the condition per DSM-5-TR, examining its epidemiology, causative agents, and clinical presentations, and differentiating it from primary psychotic disorders.<br /><br />Dr. Colombi-Vera highlighted methamphetamine as a significant cause of drug-induced psychosis, noting that injecting it greatly increases the risk of psychotic episodes. He explained that such episodes could occur during substance use, withdrawal, or even spontaneously due to chronic use. The presentation also touched on cannabis, emphasizing the increased risk of psychosis with early and daily high-THC use, and highlighted other substances such as alcohol, cocaine, and synthetic cannabinoids that contribute to psychosis.<br /><br />The discussion explored treatment approaches for acute and long-term management of substance-induced psychosis, stressing the importance of stopping the offending substance, using antipsychotics for short-term management, and ongoing monitoring for transitions to schizophrenia-spectrum disorders. Prevention and education, reinforced by a collaborative care model involving addiction treatment, family, and healthcare providers, were underscored as crucial for managing and reducing recurrence. The presentation concluded with an emphasis on timely recognition and intervention as pivotal to effectively addressing and potentially reversing substance-induced psychosis.
