Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer: A randomized double-blind trial

December 1, 2016 / Anxiety Disorders / PTSD, Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose (1 or 3 mg/70 kg) vs. a high dose (22 or 30 mg/70 kg) of psilocybin administered in counterbalanced sequence with 5 weeks between sessions and a 6-month follow-up. Instructions to participants and staff minimized expectancy effects. Participants, staff, and community observers rated participant moods, attitudes, and behaviors throughout the study. High-dose psilocybin produced large decreases in clinician- and self-rated measures of depressed mood and anxiety, along with increases in quality of life, life meaning, and optimism, and decreases in death anxiety. At 6-month follow-up, these changes were sustained, with about 80% of participants continuing to show clinically significant decreases in depressed mood and anxiety. Participants attributed improvements in attitudes about life/self, mood, relationships, and spirituality to the high-dose experience, with >80% endorsing moderately or greater increased well-being/life satisfaction. Community observer ratings showed corresponding changes. Mystical-type psilocybin experience on session day mediated the effect of psilocybin dose on therapeutic outcomes.

The Therapeutic Potential of Ayahuasca

December 1, 2016 / Anxiety Disorders / PTSD, Ayahuasca, Biology & Ethnobotany, Depressive Disorders, Papers, Psychology, Publications / By / ,

Abstract

Ayahuasca is a plant-based psychoactive decoction traditionally utilized by cultural groups throughout parts of Brazil, Peru, Colombia, Bolivia, Venezuela, and Ecuador during rites of passage, divination, warfare, magico-religious practices, and for healing in ethnomedical contexts. Over the last 150 years, ayahuasca has entered the global sphere and become a focus of scientific inquiry due to its reported use as an effective medicine to diagnose and treat illness. As a result, the use of ayahuasca within a healing context has become widespread and prompted researchers to investigate its putative therapeutic potential. In this chapter, the authors discuss current therapeutic applications of ayahuasca to treat addiction, depression, and anxiety. In this context, we highlight several studies to help facilitate a greater understanding of the therapeutic potential of ayahuasca.

Potential Psychiatric Uses for MDMA

November 9, 2016 / Anxiety Disorders / PTSD, Depressive Disorders, MDMA, Papers, Psychology, Publications / By / ,

Abstract

Phase 2 trials of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy have demonstrated initial safety and efficacy for treatment of PTSD, with potential for expansion to depression and anxiety disorders. In these trials, single doses of MDMA are administered in a model of medication-assisted psychotherapy, differing from trials involving daily drug administration without psychotherapy. This model presents an opportunity to utilize accelerated regulatory pathways, such as FDA Breakthrough Therapy Designation, to most effectively and expeditiously test such novel approaches.

Psychedelics as Medicines: An emerging new paradigm

November 4, 2016 / Anxiety Disorders / PTSD, Depressive Disorders, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

Abstract

Scientific interest in serotonergic psychedelics (e.g., psilocybin and LSD; 5-HT2Areceptor agonists) has dramatically increased within the last decade. Clinical studies administering psychedelics with psychotherapy have shown preliminary evidence of robust efficacy in treating anxiety and depression, as well as addiction to tobacco and alcohol. Moreover, recent research has suggested that these compounds have potential efficacy against inflammatory diseases through novel mechanisms, with potential advantages over existing anti-inflammatory agents. We propose that psychedelics exert therapeutic effects for psychiatric disorders by acutely destabilizing local brain network hubs and global network connectivity via amplification of neuronal avalanches, providing the occasion for brain network “resetting” after acute effects have resolved. Anti-inflammatory effects may hold promise for efficacy in treatment of inflammation-related non-psychiatric as well as potentially for psychiatric disorders. Serotonergic psychedelics operate through unique mechanisms that show promising effects for a variety of intractable, debilitating, and lethal disorders, and should be rigorously researched.

MDMA and PTSD treatment: “PTSD: From novel pathophysiology to innovative therapeutics”

July 6, 2016 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By /

Abstract

There is a range of therapies to treat Post Traumatic Stress Disorder (PTSD) but treatment resistance remains high, with many sufferers experiencing the chronic condition. Engagement in trauma-focused psychotherapy is difficult for some patients with PTSD, especially those with extreme affect dysregulation associated with recall of traumatic memories. In recent years there have been a number of neuroscientific and clinical studies examining the potential role for adjunctive drug-assisted psychotherapy using 3,4,-methylenedioxmethamphetamine (MDMA) as a treatment for PTSD. re-visiting of a novel approach to trauma-focused psychotherapy with Used just two or three times, under careful medical supervision and specialised psychotherapy support MDMA appears to facilitate the recall of traumatic memories without the user feeling overwhelmed by the negative affect that usually accompanies such memories. This therapeutic approach began in the 1980s and was subsequently shelved in the midst of public health concerns surrounding the recreational use of the drug ecstasy. When pharmaceutical grade MDMA is used in a clinical setting it does not share the same risk profiles as ecstasy. Recent phase one neurophysiological studies and phase two clinical studies are showing promise as a potential new approach to managing treatment-resistant PTSD.

±3,4-Methylenedioxymethamphetamine: Treating PTSD in The Modern World

May 26, 2016 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By /

Abstract

Post-traumatic stress disorder (PTSD) is a serious condition that afflicts millions of individuals in the United States. Its complexity has resulted in physicians struggling to effectively implement and maintain treatment. Emerging studies suggest that ±3,4-Methylenedioxymethamphetamine (MDMA), or “ecstasy”, may prove beneficial in treating PTSD in combination with conventional psychotherapy. By acting on the 5-HT transporter in the brain, MDMA has been found to have positive effects on brain activity; encouraging neuroplasticity through the accumulation of brain-derived neurotrophic factor (BDNF). Integrating psychoactive drugs into polytrauma therapy will broaden our understanding of the components involved in maintaining wellness in the human psyche.
