Title:Ketamine: Benefits and Risks for Depression, PTSD & Neuroplasticity | Huberman Lab Podcast

In this episode, I explain how ketamine causes rewiring of brain circuits and dissociative states to relieve symptoms of depression and post-traumatic stress disorder (PTSD). I explain how ketamine impacts both the brain’s glutamate and its endogenous opioid pathways, which together regulate mood and well-being. I discuss how ketamine therapy is used clinically to treat major depression, bipolar depression, obsessive-compulsive disorder (OCD), suicidality and other psychiatric challenges. I also describe how ketamine causes the subjective effects of dissociation and euphoria and, at higher doses, is an anesthetic. I compare the different routes of ketamine administration, dosages and forms of ketamine, and if micro-dosing ketamine is effective. I also highlight the potential risks of recreational ketamine use (and the colloquial term ‘K-holes’). This episode should interest anyone interested in ketamine, treatments for depression, neuroplasticity mechanisms, psychiatry and mental health. #HubermanLab #Science Thank you to our sponsors AG1: ROKA: Eight Sleep: LMNT: Supplements from Momentous Social & Website Instagram: Threads: Twitter: Facebook: TikTok: LinkedIn: Website: Newsletter: Articles Antidepressant effects of ketamine in depressed patients: Attenuation of antidepressant and antisuicidal effects of ketamine by opioid receptor antagonism: atai Life Sciences Announces Results from Phase 2a Trial of PCN-101 (R-ketamine) for Treatment-Resistant Depression: Comparative effects of (S)-ketamine and racemic (R/S)-ketamine on psychopathology, state of consciousness and neurocognitive performance in healthy volunteers: Ketamine Metabolite (2R,6R)-Hydroxynorketamine Interacts with μ and κ Opioid Receptors: Other Resources The Science & Treatment of Bipolar Disorder (Huberman Lab episode): Timestamps 00:00:00 Ketamine 00:02:29 Sponsors: ROKA & Eight Sleep 00:05:13 Ketamine & PCP; Clinical & Recreational Use 00:09:00 Depression & Current Treatments 00:15:17 Preclinical Models of Depression & Ketamine; “Learned Helplessness” 00:22:11 Ketamine & Clinical Uses; Depression & Suicidality 00:28:32 Ketamine & Other Psychiatric Challenges; Relief & Durability 00:33:24 Sponsor: AG1 00:34:29 NMDA Receptor & Neuroplasticity 00:41:36 Excitatory & Inhibitory Communication, Seizure, NMDA Receptors & Ketamine 00:48:26 How Ketamine Functions in Brain; Acute & Long-Term Effects 00:55:36 Brain-Derived Neurotrophic Factor (BDNF) & Ketamine Therapy 01:02:28 Sponsor: LMNT 01:03:40 Ketamine & Opioid Pathway 01:10:00 Divergent Mechanisms of Immediate & Long-Term Effects 01:15:45 Habenula, Pro-Depressive Behaviors & Ketamine Therapy 01:20:36 Ketamine & Context-Dependent Strategy; Reward Pathway 01:22:45 Dissociative States 01:26:04 Doses & Routes of Administration; “K-holes”; Risk & Caution 01:32:25 Ketamine Forms; R-, S- vs R/S- Ketamine; Micro-Dosing 01:38:24 Ketamine: Effects & Therapy 01:40:40 Zero-Cost Support, YouTube Feedback, Spotify & Apple Reviews, Sponsors, Momentous, Social Media, Neural Network Newsletter The Huberman Lab podcast is for general informational purposes only and does not constitute the practice of medicine, nursing or other professional health care services, including the giving of medical advice, and no doctor/patient relationship is formed.
