If psychedelics heal, how do they do it?

mycolabadmin

Psychedelic drugs like MDMA and magic mushrooms are showing remarkable promise in treating serious mental health conditions like PTSD and depression, with clinical trials demonstrating higher success rates than traditional therapy alone. However, scientists still don’t fully understand how these drugs work at the molecular and brain level, or whether the hallucinations they produce are necessary for healing. Researchers are investigating whether modified versions without hallucinations could provide the same benefits while being easier to administer, while also exploring how individual factors and treatment environment affect outcomes.

Psilocybin’s effects on cognition and creativity: A scoping review

mycolabadmin

This comprehensive review examines how psilocybin affects thinking abilities and creativity. Researchers found that large doses initially impair mental performance during the experience, but small doses may enhance creativity. Importantly, the cognitive effects appear to improve after the acute effects wear off, suggesting initial impairment doesn’t cause lasting damage. The review emphasizes the need for more rigorous long-term studies to better understand psilocybin’s effects on brain function.

Psilocybin in the real world: Regulatory, ethical, and operational challenges in Australia’s clinical landscape

mycolabadmin

Australia has approved psilocybin as a treatment for severe depression, but the rollout faces major practical challenges. Only a handful of psychiatrists are authorized to prescribe it, treatment costs over $20,000 per person, and there are no standardized training programs for therapists. The therapy can profoundly alter patients’ beliefs and worldviews, raising ethical concerns about proper support during and after treatment. The article proposes solutions including national training standards, better funding access, and stronger safeguards for vulnerable patients.

Exploring the neurobiological correlates of psilocybin-assisted psychotherapy in eating disorders: a review of potential methodologies and implications for the psychedelic study design

mycolabadmin

This review examines how psilocybin-assisted therapy might work for eating disorders by looking at various ways to measure changes in the brain. The authors discuss different brain imaging techniques and other tools that scientists could use to understand how psilocybin affects the brains of people with eating disorders. They emphasize that combining multiple measurement approaches provides the best understanding of how this emerging treatment works and can guide future research and clinical applications.

Psychedelics for the Treatment of Obsessive–Compulsive Disorder: Efficacy and Proposed Mechanisms

mycolabadmin

Psilocybin mushrooms show promise as a treatment for obsessive-compulsive disorder (OCD), a condition where people experience unwanted intrusive thoughts and compulsive behaviors. Current standard treatments with antidepressants don’t work for many patients and take weeks to show effects. Early research suggests psilocybin may reduce OCD symptoms quickly and works in treatment-resistant cases, though more rigorous studies are needed to confirm its effectiveness and understand how it works in the brain.

Synergistic, multi-level understanding of psychedelics: three systematic reviews and meta-analyses of their pharmacology, neuroimaging and phenomenology

mycolabadmin

This comprehensive study analyzed three classic psychedelic drugs—LSD, psilocybin (from magic mushrooms), and DMT—across three levels: how people experience them, how they affect brain activity, and how they interact with brain receptors. Researchers found that LSD produces more intense visual experiences than psilocybin, and all three drugs significantly alter brain connectivity patterns. The study highlights the importance of standardizing research methods to better understand how these compounds might help treat depression and addiction.

Social pain: A systematic review on interventions

mycolabadmin

This study reviews different treatments for social pain—the emotional hurt from rejection and social exclusion. Researchers found that regular pain reliever acetaminophen, mindfulness meditation, and the psychedelic compound psilocybin can reduce social pain, while placebo pills also help when people believe they work. Interestingly, combining acetaminophen with forgiveness works better than either alone, suggesting that both physical and emotional pain may use similar brain pathways.

Ketamine induces multiple individually distinct whole-brain functional connectivity signatures

mycolabadmin

This study examined how ketamine, a promising depression treatment, affects different people’s brains in different ways. Rather than averaging brain scans across all participants, researchers looked at individual differences and found that each person showed unique patterns of brain activity changes. The research suggests that personalized approaches to ketamine treatment, based on individual brain responses, could help identify which patients would benefit most from the therapy.

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat

mycolabadmin

Researchers studied how meditation combined with a psychedelic compound called DMT affects the brain. They scanned 40 experienced meditators before and after a 3-day retreat, with some receiving the psychedelic and others a placebo. While meditation alone reduced connections between different brain networks, the psychedelic enhanced certain connections, suggesting the two practices may complement each other in promoting mental health.

The therapeutic potential of microdosing psychedelics in depression

mycolabadmin

This review examines whether taking very small doses of psychedelic drugs like LSD and psilocybin might help treat depression. While users report benefits and some studies show subtle positive effects on mood and thinking, scientists have not yet confirmed whether microdosing actually works as a depression treatment. More research with depressed patients is needed to understand if this approach is truly helpful and safe for regular use.
