We brought Monica Rivera Mindt, Ph.D., ABPP-CN, back on the podcast to discuss the cognitive effects of opioid use (both licit and illicit). We discuss the history of the opioid epidemic in the U.S., the neurobiology of opioids, and common treatments for opioid use disorder. Visit the post for episode 21 to read Monica’s bio and listen to our conversation with her about cultural neuropsychology.
