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 post-traumatic stress disorder (PTSD) is prolonged exposure therapy. However, few studies have investigated psilocybin's potential effect on fear learning paradigms. More specifically, the extents to which dose, timing of...
In recent years, scientists have initiated a renaissance in psychedelic research following decades of prohibition. Compounds such as ketamine, LSD, and psilocybin 'once primarily associated with recreational use' are now being investigated for their therapeutic potential, with promising results. An estimated 40-60% of people with post-traumatic stress disorder (PTSD) do not respond to selective...
Post-Traumatic Stress Disorder (PTSD) is a debilitating mental health condition that can occur after experiencing or witnessing a traumatic event. The impact of PTSD extends beyond the individual, affecting families, communities, and society as a whole. This study aims to investigate the potential of psilocybin as a treatment for PTSD. Psilocybin, after being metabolized to psilocin, binds to...

Abstract Introduction: The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) contains a dissociative subtype of post-traumatic stress disorder (PTSD) characterized by depersonalization and derealization. Yet, there is evidence that dissociative symptoms in PTSD go beyond this kind of detachment dissociation and that some patients present with additional...
AbstractBackground and AimsPost-Traumatic Stress Disorder (PTSD) is a debilitating condition that affects a sizable proportion of U.S. civilians, military personnel, and veterans. 3,4-Methylenedioxymethamphetamine-Assisted Therapy (MDMA-AT) is a novel treatment approach for PTSD that has both stirred media enthusiasm and drawn criticism. This critical review analyzes individual randomized,...
Psychedelic compounds have potentially rapid, long-lasting anxiolytic, antidepressive and anti-inflammatory effects. We investigated whether the psychedelic compound (R)-2,5-dimethoxy-4-iodoamphetamine [(R)-DOI], a selective 5-HT2A receptor partial agonist, decreases stress-related behavior in male mice exposed to repeated social aggression. Additionally, we explored the likelihood that these...
Sleep disturbances are an important symptom dimension of post-traumatic-stress-disorder (PTSD). There is no meta-analytic evidence examining the effects of all types of pharmacotherapy on sleep outcomes among patients with PTSD. Medline/Embase/PsychInfo/CENTRAL/clinicaltrials.gov/ICTRP, reference lists of published reviews and all included studies were searched for Randomised Controlled Trials...
MDMA-assisted psychotherapy has shown potential as an effective treatment for post-traumatic stress disorder (PTSD). Preclinical studies involving rodents have demonstrated that MDMA can facilitate the extinction of fear memories. It has been noted that MDMA impacts oxytocin neurons and pro-inflammatory cytokines. Thus, the aim of this study was to explore the role of oxytocinergic signaling...
A recent decision by the U.S. Food and Drug Administration's (FDA) advisory committee to reject psychedelic treatment and therapy to treat post‐traumatic stress disorder (PTSD), citing that the available evidence of midomafetamine, better known as MDMA, fails to show that the drug is effective, has been met with mixed reaction by a member of the field and an advocacy organization committed to...
Last week, the Food and Drug Administration (FDA) voted 9‐2 to reject the application of Lykos Therapeutics, the newly formed commercial arm of MAPS, for “midomafetamine” (actually MDMA, or methylenedioxymethamphetamine) to treat post‐traumatic stress disorder (PTSD).
Mindfulness-Based Cancer Recovery (MBCR) program is a group course training for cancer patients that combines cancer knowledge and psychological knowledge, emphasizing focusing on the psychosomatic symptoms of cancer patients. Currently, the application value of Mindfulness-Based Cancer Recovery in improving psychosomatic health of cancer patients has been confirmed, however, its intervention...
Ketamine-assisted psychotherapy (KAP) is an emerging treatment option to alleviate treatment-resistant affective disorders, but its long-term effectiveness remains unclear. To examine the treatment effects of KAP on anxiety, depression, and post-traumatic stress disorder (PTSD) at 1, 3, and 6 months post-treatment. This retrospective effectiveness study included self-reported outcomes from...
Ayahuasca (AYA) is a botanical psychedelic with promising results in observational and small clinical trials for depression, trauma and drug use disorders. Its psychoactive effects primarily stem from N,N-dimethyltryptamine (DMT). However, there is a lack of research on how and where AYA acts in the brain. This study addressed these questions by examining the extinction of aversive memories in...
Post-traumatic stress disorder (PTSD) is an often debilitating condition caused by a person’s exposure to traumatic events. Symptoms of PTSD include intrusive thoughts, suicidal ideation, and highly negative and distressing emotional states. Current treatments for PTSD such as cognitive behavioral therapy, EMDR, and SSRIs and SNRIs are ineffective for a large chunk of patients who seek out...

Several studies suggested the efficacy of dispositional mindfulness and mindfulness-based interventions in reducing anxiety and depression in cardiovascular diseases. However, data on the impact of mindfulness on the psychological well-being of patients with an implantable cardioverter-defibrillator (ICD) are scarce. In this study, 422 patients with an ICD were prospectively recruited. Logistic...
This case study explores how an Intensive Care Paramedic (ICP) experienced a significant decline in his diagnosed chronic post-traumatic stress disorder (PTSD) and co-morbid depression and anxiety symptoms following a spontaneous episode of Rapid Atrial Fibrillation (AF) treated with ketamine and cardioversion emergency medical intervention. This article explores how by using therapeutic...

Emerging evidence supports mindfulness as a potential psychotherapy for post-traumatic stress disorder (PTSD). Individuals with subthreshold PTSD experience significant impairment in their daily life and functioning due to PTSD symptoms, despite not meeting the full diagnostic criteria for PTSD in DSM-5. Mindfulness skills, including non-judgmental acceptance, attentional control and openness...
Stress affects the brain and alters its neuroarchitecture and function; these changes can be severe and lead to psychiatric disorders. Recent evidence suggests that astrocytes and microglia play an essential role in the stress response by contributing to the maintenance of cerebral homeostasis. These cells respond rapidly to all stimuli that reach the brain, including stressors. Here, we used a...
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 antidepressants target the 5-HT system,...
Australia has just rescheduled two drugs controlled under the United Nations Psychotropic Drug Conventions, psilocybin and MDMA, as treatments for treatment-resistant depression and post-traumatic stress disorder respectively. This feature explores the reasons for these developments, the opportunities and challenges they provide to psychiatry communities and how along with health systems these...
