Anna Lembke, M.D.: 多巴胺是一种神经递质,是所有增强性物质和行为的最终共同通路。它在大脑的奖励回路中发挥作用,包括前额叶皮层等区域。成瘾的诊断基于行为模式,包括失控使用、强迫使用、渴望和尽管后果仍在继续使用,以及耐受性和戒断反应。成瘾的风险因素包括遗传因素、后天因素和环境因素。通过禁欲可以重置大脑的奖励系统,改善心理健康。然而,戒断过程可能很痛苦,需要根据药物的不同进行相应的干预措施。对于行为成瘾,例如赌博成瘾和性成瘾,其诊断和治疗也遵循类似的框架。不同个体对不同物质或行为的成瘾倾向存在差异,这与遗传、环境和可及性等因素有关。在治疗过程中,了解患者的个人经历至关重要。 Peter Attia: 讨论了多巴胺在成瘾中的作用,以及前额叶皮层作为“刹车”的作用。探讨了成瘾的临床定义、诊断标准以及不同成瘾类型(如酒精、赌博、大麻、性、社交媒体、运动)的具体表现。分析了成瘾的遗传、环境和社会因素,以及不同个体对不同成瘾物质或行为的易感性差异。讨论了如何帮助患者安全戒断成瘾物质,以及从戒断到长期康复的策略。探讨了行为成瘾(如性成瘾)的特征以及性别差异。分析了全球成瘾率上升的原因,以及如何应对年轻人(特别是男性)的色情成瘾问题。讨论了健康应对策略(如运动、冷水浸泡)、棉花糖实验及其对行为的影响,以及GLP-1激动剂在成瘾治疗中的潜在作用。最后,讨论了12步互助小组的益处以及如何应对工作的挑战。

Deep Dive

Chapters
The discussion delves into the biochemistry and neurobiology of dopamine, its role in reward and motivation, and the function of the prefrontal cortex in controlling addictive behaviors.
  • Dopamine is a neurotransmitter involved in pleasure, reward, and motivation.
  • The prefrontal cortex acts as the 'brakes' on the brain's reward system, allowing for delayed gratification and future consequence appreciation.
  • Addiction can result from too little control from the prefrontal cortex or too much stimulation from the reward circuitry.

Anna Lembke is the Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic and author of Dopamine Nation: Finding Balance in the Age of Indulgence. In this episode, Anna dives deep into the biochemistry and neurobiology of addiction, exploring the critical role of dopamine and the prefrontal cortex. She shares her framework for diagnosing and treating addiction, providing real-world examples involving alcohol, gambling, cannabis, social media, and more. Anna outlines the risk factors for addiction, including inherited and nurture-based risks, explores the rise of addictions in younger generations, and discusses effective ways to address these issues with children. Additionally, she touches on healthy coping strategies, the evolution of the “marshmallow experiment,” and provides insights into GLP-1 agonists as a possible tool for addiction treatment. Finally, she reflects on the value of 12-step programs and how she navigates the emotional challenges of her work.

We discuss:

  • The role of dopamine and the prefrontal cortex in addiction [3:00];
  • The clinical definition of addiction and the behavioral criteria for diagnosing it [13:00];
  • Assessing alcohol use: patterns, risks, and addiction diagnosis [17:15];
  • Applying the addiction diagnosis framework using gambling as an example [21:45];
  • Exploring addiction variability: how nature, nurture, and access shape individual vulnerability and drug of choice [25:15];
  • How abstinence from addictive behaviors can help reset the brain’s reward system and improve mental health [41:15];
  • Safely abstaining from addiction substances, drugs needing medical supervision, and other key considerations [51:30];
  • Transitioning from abstinence to long-term recovery: tools and considerations [59:00];
  • Exploring behavioral addictions like sex addiction, and the gender differences in addiction patterns [1:08:30];
  • Factors contributing to the increasing levels of addiction across the world [1:13:45];
  • How online pornography can affect young boys' developing brains and lead to addictive behaviors, and strategies for parents to address this issue [1:23:30];
  • The link between social media use and declines in mental health, potential solutions, and protective measures [1:34:45];
  • How exercise affects brain chemistry, the role of dopamine and endorphins, and how exercise can become addictive [1:44:00];
  • Cold-water immersion for mood regulation, and other healthy coping strategies [1:47:15];
  • The “marshmallow experiment”: how broken promises affect behavior and trustworthy environments help children develop self-control [1:54:00];
  • Can GLP-1 agonists be useful in treating addiction? [1:58:30];
  • The benefits of 12-step programs [2:06:00];
  • Why understanding a patient’s story is essential for meaningful psychiatric care [2:11:45]; and
  • More.
