BACKGROUND: People with HIV (PWH) are disproportionately affected by cigarette use, with a 40 - 70% prevalence rate. Although many express a strong interest in quitting, many PWH who smoke experience lower cessation rates with traditional treatments, in part due to their comorbid anxiety and depressive symptoms. Psilocybin, a classic psychedelic referred to ...
Background and HypothesisVisual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; e.g., Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; e.g., psilocybin and mescaline). While these classes of VH differ in etiology, shared pathways are suggested by overlapping phenomenology and neural mechanisms. T...

Background Recent years have seen renewed clinical interest in the therapeutic potential of classical psychedelics, such as psilocybin, LSD, DMT, and mescaline. While modern studies have focused on adult populations, adolescents under 18 are routinely excluded due to regulatory, legal, and ethical challenges. Although there exists observational data and hist...
Psychoactive substances are compounds that can influence perception, consciousness, cognition, and emotions. The psychoactive substances caffeine, nicotine, cannabis, and psilocybin all originate from natural sources and can be used without complex processing or synthesis. Their natural availability has contributed to a long-standing history of human use and...
Parkinson’s Disease (PD) is a progressive neurodegenerative disorder marked by motor symptoms due to dopaminergic degeneration and non-motor symptoms such as depression, anxiety, and cognitive impairment, which significantly affect patients' quality of life. Traditional dopaminergic therapies address motor symptoms but offer limited efficacy for neuropsychia...
Trauma-related disorders and substance use are disproportionately underdiagnosed and undertreated in individuals with High-Functioning Autism (Level 1 Autism Spectrum Disorder), particularly those in underserved or marginalized communities. Emerging evidence suggests that psychedelic-assisted therapies-including psilocybin, MDMA, and ketamine-offer promising...
Human neuroimaging with functional Magnetic Resonance Imaging has been a key feature of the current wave of psychedelic research, in both healthy and clinical populations. The available data has suggested that classic psychedelics (psilocybin, LSD, DMT) have a characteristic effect of acutely and profoundly disrupting the normal pattern of resting-state conn...
Psychedelic drugs, known for their potent psychoactive effects, have gained attention for their potential therapeutic benefits in treating mental disorders.However, distressing experiences induced by psychedelics can lead to adverse long-term effects. To better assess these experiences, we aimed to provide a Norwegian translation and psychometric validation ...
Psilocybin, a serotonergic psychedelic, has emerged as a promising treatment for a range of mental health conditions, including anorexia nervosa. Recent insights from animal models and human imaging studies suggest psilocybin enhances cognitive flexibility and modifies reward processing - two core processes disrupted in anorexia nervosa. Both cognitive flexi...
Microdosing, the repeated use of psychedelic substances at low doses, is growing in popularity among recreational consumers. While this practice is associated with many benefits to mood, well-being and health, research in this area is in its early stages and predominantly centered on human applications. In this narrative review, we synthesize the findings fr...
Abstract Major depressive disorder (MDD) is a leading cause of disability that affects over 300 million people globally. Despite multiple antidepressant trials, approximately one-third of MDD patients remain symptomatic, progressing to treatment-resistant depression (TRD). This persistence possibly is due to the multifaceted etiology of TRD, encompassing bio...
Most Delphi studies primarily rely on questionnaires and subsequent quantitative ratings across multiple rounds to learn about a complex issue. This article demonstrates the integration of qualitative inquiry into a Delphi study to enhance and complement quantitative findings. We conducted a mixed methods Delphi study to establish a comprehensive list of qua...
Abstract PcncAAAD is a calcium-activatable noncanonical aromatic L-amino acid decarboxylase (AAAD) featuring a unique appendage C-terminal domain (CTD) and two metal-binding sites. In this study, we establish an in silico RMSD-based evaluation model through molecular dynamics simulations, validated by in vitro enzyme assays, to decipher the enzyme’s calcium ...
This chapter reviews the effects of classic psychedelics on human oscillatory brain activity, as measured by resting-state electroencephalography (EEG) and magnetoencephalography (MEG). Across moderate to high doses of LSD, psilocybin, ayahuasca, and DMT, a consistent reduction in alpha power (8-13 Hz) emerges, particularly in occipital regions. Below 30 Hz,...
Psilocybin is an active alkaloid found in magic mushrooms (Psilocybe cubensis). It is classified as a Class I Psychoactive Substance due to its psychoactive properties. Recent research has suggested that psilocybin holds potential for treating major depressive disorder. The objective of this study was to develop a physiologically based pharmacokinetic (PBPK)...
Psychiatric disorders are marked by habitual patterns of thought, emotion, and behavior, and many mental health disorders are resistant to standard treatments (1)(2)(3)(4). For example, symptoms of major depressive disorder include ruminative negative thoughts, pervasive sadness, and lack of goaldirected behavior (5)(6)(7). Similarly, many anxiety and trauma...
Psilocybin-assisted therapy (PAT) has gained recognition as an innovative intervention in hospice and palliative care, demonstrating potential in mitigating the psychological, spiritual, and existential distress experienced by patients with serious illnesses. This article explores the role of PAT within these care settings, emphasizing its influence on vario...
Neuroplasticity, the ability of the nervous system to adapt throughout an organism's lifespan, offers potential as both a biomarker and treatment target for neuropsychiatric conditions. Psychedelics, a burgeoning category of drugs, are increasingly prominent in psychiatric research, prompting inquiries into their mechanisms of action. Distinguishing themselv...
