Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees

mycolabadmin

This study followed 52 people who attended psilocybin retreats in the Netherlands and measured their anxiety levels before, one day after, and one week after the experience. Participants showed significant reductions in both immediate anxiety (state anxiety) and long-term anxiety tendencies (trait anxiety) that lasted up to a week. The anxiety improvements were most strongly linked to feeling a sense of ego dissolution during the experience and to lasting changes in personality traits, particularly becoming less neurotic.

Discovering the Potential Mechanisms of Medicinal Mushrooms Antidepressant Activity: A Review

mycolabadmin

This review explores how medicinal mushrooms may help fight depression through several natural mechanisms. These mushrooms contain compounds that boost serotonin production, reduce brain inflammation, and promote healthy neural growth. The review also discusses psilocybin from magic mushrooms as a promising rapid-acting treatment for severe depression that doesn’t respond to conventional medications.

Comparative Efficacy and Functional Outcomes of Psychedelic-Assisted Therapies in Treatment-Resistant Depression: A Systematic Review of Recent Clinical Trials

mycolabadmin

This systematic review examines how psychedelic-assisted therapies like ketamine and psilocybin help people with severe, treatment-resistant depression that doesn’t respond to standard antidepressants. The analysis of 10 recent clinical trials shows these therapies work quickly, often providing symptom relief within days rather than weeks, and importantly, they also help people return to work and daily functioning. These treatments are generally well-tolerated with minimal cognitive side effects, suggesting they could become important new options for patients who haven’t benefited from conventional depression treatments.

Down the rabbit hole – the psychological and neural mechanisms of psychedelic compounds and their use in treating mental health and medical conditions

mycolabadmin

Psychedelic compounds like psilocybin and LSD are showing significant promise for treating various mental health conditions including depression, anxiety, and PTSD. These substances appear to work through multiple mechanisms, including inducing profound mystical experiences and increasing neuroplasticity in the brain. Research indicates that environmental and contextual factors significantly influence how effective these treatments are, and even virtual reality experiences mimicking psychedelic effects show therapeutic benefits. The field is moving toward responsible, evidence-based clinical applications of psychedelics in psychiatry.

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.

Comparing Antidepressant Effects of Psilocybin-Assisted Psychotherapy in Individuals That Were Unmedicated at Initial Screening Versus Individuals Discontinuing Medications for Study Participation

mycolabadmin

This study compared how well psilocybin therapy works for people with treatment-resistant depression depending on whether they were already off antidepressants or had stopped taking them for the study. The researchers found that both groups improved similarly in depression and anxiety symptoms after receiving psilocybin with therapy support. These results suggest that stopping antidepressants before psilocybin treatment may not reduce its effectiveness, though more research is needed to fully understand the relationship between medication status and treatment outcomes.

An Occupational Perspective on Psychedelic Therapy: A Scoping Review

mycolabadmin

This review examines how psychedelic therapy affects people’s daily lives and overall health from an occupational therapy perspective. Using interviews from nine studies, researchers found that people using psychedelics for mental health reported becoming more mindful and engaged in meaningful activities, better understanding themselves, increased motivation for positive change, and stronger connections with others and nature. The findings suggest psychedelic-assisted therapy can be understood as a meaningful occupation that enhances participation in everyday life rather than a harmful activity.

Negative affective bias in depression following treatment with psilocybin or escitalopram – a secondary analysis from a randomized trial

mycolabadmin

This research compared how psilocybin mushrooms and escitalopram (a common antidepressant) affect the way depressed people perceive emotions. Both treatments helped patients become better at recognizing positive facial expressions and less likely to misinterpret neutral or positive faces as negative. Interestingly, while both treatments improved emotional processing similarly, the improvements were connected to later mood improvement in different ways for each drug, suggesting they may work through somewhat different mechanisms in the brain.

Psychedelics and Neuroplasticity: A Systematic Review Unraveling the Biological Underpinnings of Psychedelics

mycolabadmin

This review examines how psychedelic substances like psilocybin and LSD affect brain structure and function. Research shows these compounds can increase BDNF (a protein crucial for brain health) and promote the growth of new neurons and connections between brain cells. These biological changes may explain why psychedelics have shown promise in treating depression and anxiety, with effects lasting weeks after a single dose.

Psychedelic-Assisted Therapy: Potential Benefits and Challenges in Mental Health Treatment

mycolabadmin

This review examines how psychedelic substances like psilocybin and MDMA, when combined with professional psychotherapy, show promise in treating difficult-to-treat mental health conditions including depression, PTSD, and anxiety. While early research suggests these substances could help in cases where conventional treatments have failed, the evidence is still preliminary and limited by small study sizes. Psychedelics appear to work by changing how the brain processes information and memories, though much more rigorous research is needed before they can be considered standard treatments.
