Ketamine: Benefits and Risks for Depression, PTSD & Neuroplasticity

Listen or watch on your favorite platforms

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.
