Obsessive-compulsive disorder (OCD) is a chronic neuropsychiatric condition characterized by intrusive thoughts and repetitive behaviors that cause distress and functional impairment worldwide. Although selective serotonin reuptake inhibitors and cognitive behavioral therapy are first-line treatments, a considerable proportion of patients show an insufficien...
Abstract Background Prolonged grief disorder (PGD) is a clinically distinguishable bereavement-related condition characterized by persistent yearning, identity disruption, and impaired functioning, formalized in DSM-5-TR and ICD-11 (6L72) and empirically distinguishable from but frequently co-occurring with major depressive disorder. Approximately 7 to 10 pe...
Background: Advanced Alzheimer's disease (AD) is generally regarded as a stage of irreversible functional decline. Psilocybin is known to transiently alter large-scale brain network dynamics and to induce plasticity-related mechanisms in preclinical models, yet clinical data in advanced dementia remain lacking. Case presentation: We report the case of an oct...
Mescaline, a 5-HT2A agonist psychedelic used ceremonially for millennia, lacks neuroimaging characterization due to its Schedule 1 status. Using pharmacological and resting-state fMRI in awake rats, we report mescaline's first comprehensive neurobiological profile. Acutely, mescaline produced cerebellar-selective BOLD suppression, suggesting functional disco...
The goal of this clinical trial is to evaluate whether psilocybin therapy can effectively treat depression and psychological distress in adult patients with COPD, ALS, MS, or APD who have at least 6 months life expectancy. The main questions it aims to answer are: * Can psilocybin therapy safely reduce depressive symptoms compared to low-dose control? * Will...
BACKGROUND AND PURPOSE: Methamphetamine (MA) use disorder is associated with widespread disruption of large-scale brain networks involved in cognitive control, attention, and salience processing. Resting-state functional MRI (rs-fMRI) provides a means to characterize these alterations; however, little is known about the capacity for functional network reorga...
The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significa...
Functional disorders, characterised by symptoms unexplained by organic disease, impose a significant burden on individuals and healthcare systems. Existing treatments are limited in efficacy, with no effective pharmacotherapies. There is growing evidence supporting the treatment potential of psychedelics in neuropsychiatric conditions, including several dist...
As psychedelic-assisted psychotherapy gains momentum, clinical investigation of next-generation psychedelics may lead to novel compounds tailored for specific populations. 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenethylamine reported to produce less dysphoria and subjective impairment than the psychedelic tryptamine psilocybin. Despite ...
PURPOSE/BACKGROUND: The therapeutic effects of psilocybin treatment are thought to be influenced by the subjective dose-dependent psychedelic experience, as well as the individual participant's mindset and the treatment environment. However, the relative contribution of an individual's pretreatment clinical characteristics and their subjective psychedelic ex...
Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by recurrent distressing thoughts and substantial anxiety, accompanied by repetitive behaviors or mental rituals. Individuals with OCD often have diminished quality of life, and functional impairment. The disorder cause high personal, societal and economic costs. Current availab...
BACKGROUND: Motor functional neurological disorder (FND) is a common illness associated with significant functional impairment. There are no effective pharmacotherapies, and despite the early promise of physiotherapy studies, many suffer disabling symptoms in the long term. There is a theoretical rationale for combining psychedelics with physiotherapy; howev...
Background and Aims The ongoing opioid epidemic remains a major public health crisis in the United States, with over 100,000 opioid-related deaths annually. Mental health disorders are strongly associated with opioid use disorder (OUD), compounding risks of misuse and overdose. Emerging evidence indicates that psychedelics may be associated with reduced risk...
Abstract Background Major Depressive Disorder (MDD) is a leading cause of disability and economic loss, with high recurrence and treatment resistance. Psilocybin-assisted therapy (PAT) shows promise in reducing depressive symptoms, but long-term effects are unknown. We aimed to determine the long-term safety and efficacy of PAT for MDD over a five-year follo...
Introduction In recent years, psychiatry has witnessed a renaissance in the investigation of psychedelic compounds, a broad class of psychoactive substances that induce altered states of consciousness, often characterized by changes in perception, mood, and cognition, which were largely shelved following regulatory crackdowns in the 1970s. The renewed intere...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition for which there are few efficacious treatments. Psilocybin is being studied for use in treatment-resistant depression but has not yet been investigated in PTSD. Aims: The trial’s primary outcome was to investigate the safety and tolerability of single-dose psilocybin in participant...
Psychogenic non-epileptic seizures (PNES) are functional paroxysmal motor disorders that may be clinically suggestive of epilepsy but are not associated with the electroencephysiological and electroencephalographic changes of epilepsy. Thus, hyper-connectivity of the regions of the default mode network (DMN) linked to executive control could be involved in t...
Abstract Background Obsessive-compulsive disorder (OCD) is associated with significant personal suffering and functional impairment. At least a third of OCD patients do not respond to conventional treatments. There is a substantial anecdotal literature suggesting that psychedelic agents, specifically psilocybin and psilocybin-containing psychedelic mushroom ...
