Fragile X Syndrome (FXS) is the most common inherited intellectual disability and a leading monogenic cause of autism spectrum disorder (ASD). As a synaptic disorder, FXS involves the loss of Fragile X messenger ribonucleoprotein 1 (FMRP), leading to abnormal dendrite development and immature dendritic spines. Serotonergic signaling, essential for neuronal development and circuit remodeling,...

Background: Psychological distress is a common problem near the end of life, for which we lack effective, timely and scalable treatments. No previous study has assessed whether microdose psilocybin can improve symptoms in this population. Aim: To determine whether microdose psilocybin is safe, feasible and potentially efficacious in a palliative setting. Design: Open label, single-arm clinical...
Shelter environments frequently expose dogs to chronic stress and anxiety, which can compromise their welfare and reduce their chances of adoption. Recent interest in psychedelic-assisted approaches has suggested potential therapeutic applications in veterinary behavioral medicine, although empirical evidence remains scarce. This study aimed to evaluate the combined effects of low-dose...
Lysergic acid diethylamide (LSD) has been considered as a potential treatment for depression for over 75 years, but its therapeutic potential has only recently been considered in mainstream psychiatry. Repeated ingestion of low doses of LSD ("microdoses") is thought to reduce depression, but the neurobiology underlying this effect is unknown. We previously reported that low doses of LSD...

Psychedelic-assisted therapy (PAT) is a novel intervention for depressive symptoms, typically delivered with additional psychological therapy sessions. Quantitative evidence on how this concomitant therapy contributes to treatment outcomes is limited, highlighting the need for a systematic synthesis. To evaluate whether the quantity of psychological therapy is associated with symptom reduction...
Some individuals interpret persistent depression and anxiety, alongside the exhaustion of standard treatment options, as leading to a desperate need for relief. While desperation may shape how people assess treatment options, its role in psychedelic self-treatment and its relevance for emerging clinical models of psychedelic treatment remain underexplored. We collected discussion threads from...
Obsessive-Compulsive Disorder (OCD) can present significant challenges to individuals mental health, characterized by intrusive thoughts and repetitive maladaptive behaviors. Recent research into alternative treatments has highlighted psychedelics, notably psilocybin, for their potential therapeutic benefits in various psychiatric disorders, including OCD. This case study evaluated the impact...

The therapeutic potential of low, non-psychedelic doses of psilocybin, a fungal tryptamine alkaloid, was investigated in metabolic disorders including obesity, type 2 diabetes mellitus (T2DM), and liver steatosis. Mice fed a high-fat/high-fructose diet received chronic treatment with psilocybin (0.05 mg/kg) for 12 weeks. Body weight, liver histology, insulin sensitivity, and skeletal muscle...
Low-dose psychedelics have shown potential in modulating chronic pain in humans, yet their application in veterinary medicine remains unexplored. This study protocol proposes to investigate the therapeutic potential of low-dose oral administration of 1-cyclopropionyl-D-lysergic acid diethylamide (1cp-LSD), a legal LSD analogue in certain countries, for the management of chronic pain in...
The popularity of the red fly agaric in the past 10 years has led not only to a positive impact on the inhabitants of Europe and Asia, but also to a number of hospitalizations and even deaths. Independent macrodosing and combination with other entheogens is especially dangerous. Based on the available literature, as well as independent field studies on volunteers, as well as police and...
