Talking Ketamine Podcast

For decades, the "trip" caused by ketamine—sensory detachment, time warping, and out-of-body experiences—was seen as a nuisance, a "bug" to be tolerated during anesthesia. But a groundbreaking 2025 review paper by Berra and colleagues asks a provocative question: What if dissociation is actually the point? In this episode, we dive into the "Science of Dissociation," exploring the spectrum from sim...

For decades, ketamine has been viewed primarily through two lenses: a safe anesthetic or a rapid-acting antidepressant "reset button." But a new paper by Sophie Holland argues we may be missing half the picture. This episode challenges the binary view of ketamine by exploring two distinct therapeutic pathways defined essentially by dose: the Psychedelic and the Psycholytic. The Psychedelic Path (H...

Sickle Cell Disease (SCD) pain crises are the leading cause of hospitalization for affected children, causing excruciating vaso-occlusive episodes where misshapen blood cells block oxygen flow to tissues. For decades, the standard treatment has been high-dose opioids, but this often leads to tolerance, inadequate relief, and the dangerous paradox of opioid-induced hyperalgesia —where the treatment...

"Will this actually work for me?" It is the most critical question patients ask before investing time, money, and hope into ketamine therapy. In this episode, we analyze a massive body of research—including a systematic review of 112 studies and a real-world analysis of 77 patients —to find actionable predictors of success. The results are reassuringly broad: factors like age, sex, depression seve...

urgery is a trauma that wrecks sleep, and for vulnerable patients, Post-Operative Sleep Disturbance (PSD) is a serious complication linked to delirium, increased pain, and slowed recovery. In this episode, we dive into a fascinating study that connects three seemingly unrelated dots: ketamine , sleep, and the oral microbiome . Researchers treated 130 high-risk surgical patients with a continuous l...

Catatonia is often misunderstood as simple immobility, but it is a terrifying, life-threatening syndrome of stupor, mutism, and extreme negativism—a state where the brain is essentially "frozen." For decades, the standard protocol has been to step on the "brake pedal" using GABA-ergic drugs like lorazepam , followed by Electroconvulsive Therapy (ECT) if medication fails. But what happens when the...

We move beyond depression and anesthesia to examine ketamine's role in fighting one of the most severe types of chronic pain imaginable: Complex Regional Pain Syndrome (CRPS). This condition is marked by wildly disproportionate and persistent pain , exemplified by the case of a 15-year-old athlete whose simple hand fracture healed, but whose nervous system got stuck in a pathological pain loop. Th...

Chronic mental illnesses like severe MDD (major depressive disorder) and PTSD are alarms, not just for the mind, but for the body. This episode explores the fact that ongoing trauma and depression accelerate biological aging , leading to reduced health span and higher risks for chronic diseases. But can rapid, effective psychiatric treatment actually reverse this damage? We dive into a compelling...

The KARMA-Dep2 trial delivered a shocking headline: up to eight serial ketamine infusions were no better than the midazolam placebo for hospitalized adults with moderate to severe depression. In an era of intense hope for ketamine's rapid antidepressant effects, this result demands a closer look. This episode critically dissects why this large, pragmatic trial may have failed to show a significant...

For years, the most recognized physical risk of chronic ketamine abuse has been bladder damage, but a new clinical puzzle is emerging: severe injury to the liver and bile ducts, known as Ketamine-induced Sclerosing Cholangitis (K-SC). This episode dives into a recent case series detailing patients—including older and female European users—broadening the picture of who is at risk. Sclerosing cholan...

This episode breaks down a truly radical theory of consciousness: The General Resonance Theory (GRT). Forget the traditional idea that consciousness comes from synapses firing—GRT proposes that it emerges from near-instantaneous, resonant electromagnetic field interactions within the brain, moving information up to 40,000 times faster than slow neuronal spikes. This electrical "field" is the true...

When stroke strikes, the damage doesn't stop once the blood flow is restored. This episode dives into the dark side of recovery: the Ischemia-Reperfusion (IR) Injury, a devastating "second wave" of damage that causes lasting neurological deficits. We explore a fascinating preclinical study on esketamine, the S-enantiomer of ketamine. Researchers hypothesized that this powerful NMDA receptor antago...

When traditional antidepressants fail older adults with treatment-resistant depression, where can they turn? Standard therapies, built on the monoamine hypothesis, often fall short in aging brains or those affected by neurodegenerative diseases like Alzheimer's, as the pathways they rely on may be dysfunctional. This episode dives deep into a systematic review exploring a paradigm-shifting alterna...

Ketamine is known for its powerful effects on the mind and body, but could one of its most profound secrets be the ability to fight cancer?
