Psilocybin, the active compound in so-called magic mushrooms, is currently one of the hottest topics in psychiatric research. While much about Obsessive Compulsive Disorder (OCD) remains disputed, OCD is a mental health disorder that combines obsessive thoughts and compulsive behaviour. Psilocybin is chemically very similar to serotonin, a neurotransmitter that has been implicated as a central factor in the appearance of OCD symptoms. Research has shown that psilocybin may alter functional connectivity in the brain, reducing OCD symptoms. While pre-clinical and clinical evidence remains scarce, early research has shown promising beneficial effects on OCD.

Psilocybin's effect on serotonin
Psilocybin, the psychedelic compound found in "magic mushrooms", is currently a hot topic in psychiatric research. Scientists are studying how psilocybin affects the brain and its potential therapeutic applications for various psychiatric disorders, including obsessive-compulsive disorder (OCD).
Psilocybin is chemically and structurally similar to serotonin, a neurotransmitter in our body. It interacts with the same receptors in the brain, specifically the serotonin 2A (5-HT2A) receptors. By activating these receptors, psilocybin reduces the energy required for the brain to switch between different activity states, leading to altered states of consciousness. These experiences can include heightened emotional awareness, visual and auditory phenomena, and a sense of transcendence of time and space.
The Default Mode Network (DMN) in the brain is highly involved in self-referential thinking and has been linked to OCD. Treatment with psilocybin may reset functional connectivity within the DMN, leading to reduced OCD symptoms. Additionally, the subjective transformative experiences induced by psilocybin may contribute to improved wellness, decreased stress, and better management of OCD symptoms.
While psilocybin shows promise in treating OCD, it is classified as a Schedule I substance by the DEA, complicating research efforts. Furthermore, the risk of serotonin toxicity associated with psilocybin use, especially when combined with certain medications, is a concern that requires careful monitoring.
Several clinical trials are underway to investigate the efficacy of psilocybin in treating OCD. These studies employ rigorous methodologies, including randomized, double-blind, placebo-controlled designs, to assess the impact of psilocybin on OCD symptoms and brain connectivity. The results of these trials will provide valuable insights into the therapeutic potential of psilocybin for OCD and other mental health disorders.

Psilocybin's potential to alleviate OCD symptoms
Psilocybin, the active compound in so-called "magic mushrooms", has been the subject of recent research for its potential to alleviate symptoms of OCD. While OCD currently has FDA-approved treatments, such as SSRIs, CBT, and TMS, these treatments have only been modestly effective, with many patients considered treatment-resistant.
Psilocybin is chemically and structurally similar to serotonin, a neurotransmitter that has been implicated as a central factor in the appearance of OCD symptoms. By binding with serotonin receptors and preventing serotonin reuptake, psilocybin may be able to reduce OCD symptoms. This is supported by research from the University of Arizona, which found that psilocybin significantly reduced symptoms of severe OCD after 8 weeks. The study included 15 adults with severe OCD symptoms, and at a one-week follow-up after the end of dosing, 80% of participants had a symptom reduction of 25% or more, with 40% in remission.
Other research has explored the impact of psilocybin on brain connectivity and neuronal activation in patients with OCD. One study hypothesized that psilocybin would normalize abnormal fronto-striatal functional connectivity and decrease activation in certain brain regions in response to symptom-provoking stimuli, leading to an improvement in symptomatology.
While psilocybin shows promise in treating OCD, it is not without its risks. Due to possible side effects such as panic, paranoia, drowsiness, anxiety, and psychosis, patients with a history of bipolar disorder, mania, or psychosis are discouraged from using psilocybin to treat their OCD.

Yale Medicine's double-blind, placebo-controlled study
Yale Medicine is conducting a double-blind, placebo-controlled study to investigate the efficacy of psilocybin in treating OCD. Psilocybin is a psychedelic compound found in "magic mushrooms". It is chemically similar to the neurotransmitter serotonin and interacts with the same receptors in the brain.
The study will involve 30 participants who will be randomly divided into two groups. One group will receive 0.25mg/kg of psilocybin, while the other will receive an active placebo-control agent, niacin 250mg. The participants will be blinded to their group allocation. Both groups will also receive non-drug preparatory and follow-up support appointments. The participants will be admitted as inpatients for at least 3 nights/4 days surrounding the initial drug administration.
The study has two main aims. The first is to investigate the effects of psilocybin on OCD symptoms. The severity of OCD symptoms will be assessed before treatment and at various time points after treatment, including 24 and 48 hours, one week, two weeks, one month, and three months. The researchers hypothesize that the psilocybin group will show greater symptom improvement than the placebo group at all assessment points.
The second aim is to explore the relationship between psilocybin-induced brain connectivity changes and neuronal activation following symptom provocation in OCD. Resting-state brain connectivity will be assessed before and 48 hours after treatment. The researchers hypothesize that psilocybin will normalize abnormal fronto-striatal functional connectivity in patients with OCD and decrease activation in certain brain regions in response to symptom-provoking stimuli. They further hypothesize that normalization of these abnormalities will correlate with improvement in symptoms after psilocybin treatment.
The results of this study will provide valuable insights into the potential therapeutic benefits of psilocybin for OCD.

Side effects and risks
While psilocybin, the active compound in "magic mushrooms", has been shown to have therapeutic benefits for OCD, it also has several side effects and risks associated with its use.
Psilocybin interacts with serotonin receptors in the brain, and larger doses can cause hallucinations, a feeling of euphoria, and spiritual or introspective experiences. However, it can also cause panic, paranoia, drowsiness, anxiety, and psychosis, also known as a "bad trip". Due to these potential side effects, psilocybin treatment may not be suitable for individuals with a history of bipolar disorder, mania, or psychosis.
In addition, psilocybin is classified as a Schedule I substance by the US Drug Enforcement Administration (DEA), which means that it has a high potential for misuse and has no currently accepted medical use. This classification complicates research efforts and access to the drug for therapeutic purposes.
Furthermore, the effects of psilocybin are highly variable and depend on factors such as dose, purity, and individual mindset and setting. The benefits may also be transient, as reported by some individuals, lasting only 1-2 weeks and not occurring every time.
While psilocybin has shown promising results in early research, careful clinical data and long-term follow-up are still needed to fully understand its safety and efficacy as a treatment for OCD.

Psilocybin's classification as a Schedule I substance
Psilocybin, the psychedelic compound found in "magic mushrooms", is currently classified as a Schedule I substance by the US Department of Justice Drug Enforcement Administration (DEA). This classification is given to drugs or substances that have a high potential for abuse and no currently accepted medical use in the US. Drugs in this category also lack accepted safety profiles for use under medical supervision, and prescriptions may not be written for them.
However, recent research has indicated that psilocybin may have therapeutic benefits for various psychiatric disorders, including obsessive-compulsive disorder (OCD). OCD is a debilitating mental health disorder characterised by recurring obsessive thoughts, images, or urges that lead to compensatory repetitive compulsive behaviours. The unique symptoms and associated stigma often make it difficult for those affected to seek help.
Psilocybin's therapeutic potential in OCD is attributed to its ability to alter functional connectivity within the Default Mode Network (DMN) in the brain, which is highly active in individuals with OCD. Preliminary clinical research suggests that psilocybin may reduce OCD symptoms by resetting functional connectivity within the DMN, leading to improved wellness, decreased stress, and reduced compulsive behaviours.
In light of these findings, researchers from Johns Hopkins University have recommended that psilocybin be reclassified as a Schedule IV substance, which includes prescription sleep aids. They argue that psilocybin has a relatively low risk of harm and low abuse potential compared to other drugs, and that its reclassification could facilitate its path to clinical use. While the researchers acknowledge that psilocybin should remain under the supervision of healthcare professionals, they believe that its reclassification could streamline its implementation in clinical settings.
