Understanding Addiction: Prevalence, Brain Changes, Diagnostic Criteria, and Recovery Challenges

This podcast episode, hosted by Dr. Dawn Elise Snipes, delves into the complex landscape of addiction, covering its prevalence, symptoms, course, and diagnostic criteria. It begins by presenting statistics from the National Survey on Drug Use and Mental Health, comparing 2012 and 2021 data on heavy drinking and illicit drug use, noting the significant impact of marijuana legalization on reported illicit drug use figures. Dr. Snipes highlights that these statistics likely underestimate the true scope of substance use disorders and entirely omit behavioral addictions like gambling, internet gaming, and shopping, emphasizing the broad spectrum of addictive behaviors.

The episode clarifies that "addiction" itself is not a DSM-5 TR diagnosis but rather a primary, chronic disease affecting brain reward, motivation, memory, and related circuitry. It explains how substance use and process addictions cause physiological changes in the brain, leading to rewiring and dysregulation of neurotransmitters like dopamine and endogenous opioids, which in turn affect mood, energy, and pain perception. The discussion underscores that recovery involves a complex process of brain remodeling, and failure to address process addictions can hinder true healing by maintaining dysfunctional neural circuits. The chronic disease model is defended, asserting that addiction disrupts normal functioning, has serious consequences, is preventable, and can be fatal if untreated, while also acknowledging the underlying pain and distress that often drive initial use.

Dr. Snipes provides a detailed breakdown of the DSM-5 TR criteria for Substance Use Disorder (SUD), introducing the mnemonic "TWCrapOut" to remember the nine symptoms (Tolerance, Withdrawal, Cravings, Repeated attempts to quit, Amount of time spent, Precluded activities, Ongoing use despite harm, Risky situations, Trouble with social relationships). She emphasizes that only two symptoms within a 12-month period are needed for a diagnosis, and tolerance or withdrawal are not mandatory. The episode also distinguishes between mild, moderate, and severe SUD, as well as early and sustained remission, noting the ongoing challenge of cravings even in sustained recovery and the complexities of medication-assisted therapy in these definitions. NAAC's differing criteria for mild, moderate, and severe use are also briefly discussed.

Finally, the physiological course of addiction is explained, detailing how initial surges of pleasure chemicals lead to repeated reward-seeking, disrupting the brain's homeostasis. This repeated overload causes the brain to adapt, becoming tolerant and resistant to neurochemicals, leading to withdrawal symptoms when the substance or process is absent. The episode stresses that addiction is a learned behavior that is difficult to unlearn, requiring lifelong management, especially for process addictions like food or sex where complete abstinence is not feasible. It concludes by reiterating the importance of addressing the root causes of pain and distress that drive addictive behaviors, rather than solely focusing on substance removal, to prevent relapse and promote genuine recovery.

"Addiction is a primary chronic disease of brain reward motivation memory and related circuitry."

"You can't monkey if you will with any of the neurotransmitters without affecting all of his buddies."

"Dysfunction in these brain circuits leads to characteristic biological psychological social and spiritual manifestations reflected in a pathological pursuit of a reward and or Relief by a substance or process."

"Addiction is a progressive condition and can result in disability or premature death."

"Many people don't like that term disease they're like well it gives people an excuse to use because they say they have a disease no it doesn't."

"Preventing people from being able to access a substance is fool hearty if we look back over way back in alcohol prohibition."

"Addiction is a chronic lifetime disease or condition that people are going to have to cope with."

"You only need two of these criteria to appear at some point over the course of 12 months to diagnose somebody with a substance use disorder."

"Homeostasis means balance this is the way everything is in a very particular balance."

"Addictive behaviors are used to numb or quill pain or discomfort whether it's physical or emotional."
