There is controversy about a causal role of serotonin (5-HT) in depression, some arguing that there is no proof for impaired brain 5-HT function in depressed patients. Major depressive disorder comes with multiple endophenotypes; not surprisingly classical antidepressants (tricyclics, MAO inhibitors, SSRIs, SNRIs) are not universally effective. Most antidepr...
Prolonged Grief Disorder (PGD) is distinct from yet related to non-pathologic grief, depression, addiction, and Post-Traumatic Stress Disorder (PTSD) with a prevalence of up to 10% in bereaved populations. Hallmarks of PGD include functional impairment a year or more post-bereavement and intense yearning for the deceased. Current treatments for PGD are typic...
ABSTRACT A variety of classic psychedelics and MDMA have been shown to enhance fear extinction in rodent models. This has translational significance because a standard treatment for posttraumatic stress disorder (PTSD) is prolonged exposure therapy. However, few studies have investigated psilocybin’s potential effect in fear learning paradigms. More specific...
We aim to systematically review and meta-analyze the effectiveness and safety of psychedelics [psilocybin, ayahuasca (active component DMT), LSD and MDMA] in treating symptoms of various mental disorders. Web of Science, Embase, EBSCO, and PubMed were searched up to February 2024 and 126 articles were finally included. Results showed that psilocybin has the ...
ObjectiveThis study aims to provide an overview of pharmacological trials that examine the neurocognitive effects of psychedelics among healthy individuals and patients with post-traumatic stress disorder (PTSD) or major depressive disorder (MDD).MethodsThe Preferred Reporting Items for Systematic Reviews (PRISMA) was used as a guide to structure and report ...
Post-traumatic stress disorder (PTSD) is a debilitating disorder inflicting high degrees of symptomatic and socioeconomic burdens. The development of PTSD results from a cascade of events with contributions from multiple processes and the underlying pathophysiology is complex, involving neurotransmitters, neurocircuitry, and neuroanatomical pathways. Present...
IntroductionPost-traumatic stress disorder (PTSD) is associated with significant patient burden. While pharmacotherapies and evidence-based psychotherapy interventions (EBPI) are effective, studies consistently highlight inadequate outcomes and high treatment dropout. Psychedelic therapy (PT) has shown preliminary promise across difficult-to-treat conditions...
Psilocybe cubensis is a species of psilocybin mushroom (magic mushroom) of moderate potency whose principal active compounds are psilocybin and psilocin. Recent studies have shown the significant procognitive and mood-enhancer effects of Psilocybe cubensis. However, evidence is so limited, especially in preclinical studies. We aimed to investigate the effect...
The purpose of this study is to evaluate the safety, tolerability, and potential efficacy of psilocybin-assisted psychotherapy to reduce post-traumatic stress disorder (PTSD) severity in a sample of individuals with PTSD. The proposed Phase I study aims to evaluate the safety, tolerability, and potential efficacy of psilocybin-assisted psychotherapy to reduc...
“Pretty girls don't buy cocaine,” Greta1 says and laughs as she walks out the front door.My hands and face sting as I stand frozen in the entryway and hear her start the car. I'd asked my twenty-two-year-old daughter where she got the money to feed the addictions she was battling.Over the past three years, she'd chosen a few subpar boyfriends who introduced ...
Abstract A review of the literature on posttraumatic stress disorder (PTSD) suggests it to be a complex disorder with many contributing factors. The concept of PTSD has continued to evolve over time. A diagnosis of PTSD may be hard to get right. Studies suggest a wide variation in its presentation and diagnostic stability. It is tempting to explore the possi...
Post-traumatic stress disorder (PTSD) is a mental health condition that can occur following exposure to a traumatic experience. An estimated 12 million U.S. adults are presently affected by this disorder. Current treatments include psychological therapies (e.g., exposure-based interventions) and pharmacological treatments (e.g., selective serotonin reuptake ...
Borderline personality disorder (BPD) and post-traumatic stress disorder (PTSD) share overlapping neurobiological mechanisms particularly reward deficiency and stress-like anti-reward processes. And so, BPD may be reclassified as a "traumatic personality stress disorder" (TPSD) with ensuing common therapeutic strategies that may stabilize dopaminergic reward...
Post-Traumatic Stress Disorder (PTSD) is a mental disorder that may develop in people who have been exposed to a traumatic event, including actual or threatened death, serious injury, or sexual violence. Exposure to a traumatic event is defined as directly experiencing the event, learning about the event, or repeated exposure to details of the event. PTSD is...
There has been a resurgence in psychedelic research for managing psychiatric conditions in recent years. This study aimed to present a comprehensive review of the current state of the field by applying a systematic search strategy for articles on the effectiveness and tolerability of four psychedelic-assisted therapies (psilocybin, lysergic acid diethylamide...
Serotonergic hallucinogens also referred to as psychedelics, are psychoactive substances that profoundly alter perception, mood, and cognitive processes. These substances, historically intertwined with religious and cultural rituals, offer profound effects that extend beyond mere hallucinations to profoundly altered states of consciousness. Notable compounds...
Purpose of reviewThis review discusses the current and projected landscape of psychedelic-assisted therapy (PAT), with a focus on clinical, legal, and implementation considerations in Department of Defense (DoD) and Department of Veterans Affairs (VA) healthcare systems.Recent findings3,4-Methylenedioxymethamphetamine (MDMA)- and psilocybin-assisted therapy ...
This review aims at RCT's of psychedelics used in the treatment of depression and PTSD. Psilocybin has shown an antidepressant effect in cancer patients that was sustained at 6- and 12-months follow-up. The effect of psilocybin was comparable to escitalopram in one study. Ketamine has shown effect for the treatment of resistant depression. Phase 2 and 3 tria...
