A recent placebo-controlled trial has revealed that a single dose of psilocybin, the active compound in magic mushrooms, significantly alleviates symptoms of obsessive-compulsive disorder (OCD). Remarkably, these effects last for at least 12 weeks, suggesting psilocybin could offer enduring relief for OCD sufferers.

“Investing in experiences like travel can disrupt patterns of obsessive thinking and behavior,” notes Dr. David Nutt from Imperial College London, who wasn’t part of the study. “The essence of OCD treatment is to guide individuals towards behavioral change—like reducing the number of times they check the lights from 15 to 2.”

Approximately 1-3% of the population suffers from OCD, a condition marked by distressing obsessions and compulsive behaviors that can severely affect daily life. Conventional treatments often involve talk therapy and antidepressants; however, 40-60% of OCD patients fail to respond to these options.

Other psychedelics, including psilocybin and ketamine, have demonstrated therapeutic potential for various mental health disorders. To explore these possibilities, Dr. Christopher Pittenger at Yale University launched the first randomized, placebo-controlled study focused on psilocybin’s effects on OCD.

The research involved 28 adults with an average of 20 years of OCD experience who had previously undergone at least two failed treatment attempts. Participants assessed their symptom severity using a standard scale ranging from 0 to 40 and were randomly assigned to receive either a single oral dose of psilocybin (0.25 milligrams per kilogram) or niacin (250 milligrams), serving as a placebo.

The psilocybin dose was sufficient to induce a psychedelic experience, often associated with profound changes in perception, cognition, and emotion. “The intensity varies, but it’s generally quite strong,” remarks Pittenger.

Following 48 hours, participants who received psilocybin reported an average symptom score reduction of 9.76 points, while those given niacin showed minimal changes. “The rapid and enduring improvements after a single psilocybin dose are astonishing,” states Dr. Alex Kwan from Cornell University.

After one week, around 70% of participants who took psilocybin experienced a 35% decrease in symptom scores, and this effect persisted through the 12-week follow-up. “Psilocybin outperforms traditional OCD medications in both efficacy and speed,” says Nutt, who was involved in a separate clinical trial that lacked a placebo control. Research indicates that low doses of psilocybin can significantly diminish OCD symptoms.

Kwan suggests that the positive outcomes in individuals who have previously undergone several standard treatments point to psilocybin’s unique influence on the brain, though the precise mechanisms behind its efficacy in managing OCD remain unclear. “Understanding the biology behind its effects could revolutionize the treatment strategies not only for OCD but also for various mental health disorders,” he notes.

One hypothesis suggests that psilocybin enhances brain plasticity, potentially weakening entrenched thoughts that typically dominate an individual’s mindset. This flexibility is a critical challenge with all psychedelic substances, according to Nutt, who previously demonstrated that a single dose of the psychedelic DMT alleviated depression symptoms. “Individuals experiencing depressive thoughts found their thinking became more adaptable post-psychedelic experience,” he states.

Another theory posits that psilocybin recalibrates the brain’s default mode network, influencing areas linked to rumination and self-awareness, according to Pittenger. Research has also shown that a single psilocybin dose can enhance mental health by rewiring neural connections and reducing inflammation.

However, safety concerns regarding psilocybin use have emerged. In a Yale University study, a participant with a history of suicidal thoughts began to actively plan suicide during the trial. Although this risk was later mitigated through standard monitoring, Pittenger emphasizes the necessity for stringent clinical safeguards when administering psilocybin in medical contexts. Comprehensive trials are also needed to validate the drug’s efficacy, safety, optimal dosing, as well as to identify ideal candidates and those at increased risk, he adds.

A recurring challenge in psychedelic research is that participants’ experiences can often reveal whether they received the active drug or placebo. To combat this, researchers administered niacin, which can provoke sensations like facial flushing and elevated heart rate. However, many participants still discerned their treatment, according to Pittenger. “As with most studies of this nature, this presents a limitation,” he concludes.

Brain Changes from Eating Disorders Mirror Those Seen in OCD and Autism

New research indicates that children with anorexia nervosa are undergoing significant brain changes that go beyond what starvation can explain. This insight helps clarify the neurological mechanisms behind the disorder, potentially paving the way for improved treatment strategies.

Anorexia nervosa is noted for severe dietary restrictions and a distorted body image, making it a less understood condition. While previous studies have highlighted that the brain’s outer layer, or cortex, is notably thinner in these individuals, it remains uncertain whether such changes stem from malnutrition or are intrinsic to anorexia.

Clara Morrow from The University of Montreal, Canada, examined brain scans of children with anorexia alongside those with Avoidant/Restrictive Food Intake Disorder (ARFID). Although both conditions encompass significant food restrictions and weight loss, ARFID lacks the body image concerns that characterize anorexia. Instead, individuals with ARFID may avoid food due to sensory sensitivities, disinterest in eating, or fear of adverse consequences like choking, vomiting, or gastrointestinal distress. The comparison could shed light on the unique brain changes associated with each condition and malnutrition, according to Moreau.

The study analyzed brain scans from 124 children diagnosed with anorexia, 50 with ARFID, and 116 without eating disorders. All participants were under 13 years old and resided in France. Researchers examined the extent of brain differences between those with and without eating disorders.

On average, children diagnosed with anorexia exhibited a significantly thinner cortex compared to those without eating disorders. Once body mass index (BMI) was taken into account, anorexia correlated with cortical thinning across 32 brain regions, particularly in the superior head lobule, an area involved in sensory information processing. “This aligns with our understanding, as we know anorexic patients often struggle with their perception of weight and size,” stated team member Anael Ayrolles from the University of Paris.


These alterations are akin to those observed in older adolescents and adults suffering from anorexia, notes Moreau. “The effect size is among the most significant in psychiatry,” she comments. “It appears as if they’ve experienced accelerated brain aging or early Alzheimer’s disease, though they show no symptoms of Alzheimer’s. However, if their BMI is normalized, brain recovery is often observed, though not in every case.”

In contrast, no significant differences in cortical thickness were observed between children with ARFID and those without any eating disorders. “We anticipated some overlap with anorexia potentially reflective of BMI,” explains Moreau. “However, our findings did not reveal many similarities between the two conditions.” The reason for this remains unclear, especially since this is the inaugural brain imaging study focused on ARFID. Given that ARFID typically manifests before the age of five, the brain may have adapted to limited food intake, suggests Moreau.

The researchers subsequently contrasted these brain differences with findings from previous studies on other disorders, including obsessive-compulsive disorder (OCD), ADHD, and autism. They found a notable correlation between anorexia and OCD, whereas ARFID displayed brain changes similar to those associated with autism. This aligns with Moreau’s assertion that sensory sensitivity is prevalent in both autism and ARFID. Conversely, OCD and anorexia exhibit obsessions, rituals, and preconceived notions.

Nevertheless, individuals with OCD and anorexia frequently present other mental health challenges, notes Joanna Steinglass from Columbia University in New York. Approximately 14% of those diagnosed with anorexia also meet the criteria for OCD. This complicates the understanding of whether a genuine neurological resemblance exists between the two conditions or if other mental health challenges underpin this correlation.

“We were cautious not to over-interpret our results,” said Ayrolles. However, these discoveries imply that malnutrition alone may not account for all the brain changes observed in anorexia. “Mental illness is fundamentally a brain-based illness, and understanding this helps us address patient experiences more effectively, often leading to less blame,” remarks Steinglass. “This insight could drive the development of more effective treatments.”

Fresh Insights into OCD Will Lead to Innovative Treatments

When my daughter was little, she would wash her hands a lot. We might have lightly teased her, saying she was a bit OCD. Then she started to reveal “bad thoughts” that I thought were typical of a child's imagination. I told her that everyone has these thoughts and that they will go away if she ignores them.

That wasn't the case with her. At 21, her emotions were out of control and completely out of proportion to reality. She was diagnosed with OCD, and I finally realized there was nothing “a little” about this condition.

OCD is complex, widely misunderstood, and treatment options are limited. But in recent years, the brain and body mechanisms that cause OCD have finally been uncovered, revealing a complex picture that involves genetics, various brain networks, the immune system, and even gut bacteria. The resulting improved understanding is opening up new possibilities for tackling this life-destroying condition.

Around the world, It is estimated that 1-3% of people suffer from OCD.Obsessional thoughts typically begin during adolescence or early adulthood. As its name suggests, it is characterized by obsessions, or intrusive thoughts, and compulsions, which are habits that cannot be stopped. “Obsessive thoughts capture and dominate our attention because they have become obsessive habits,” says Barbara Sahakian At Cambridge University…

Reasons to stop making light of having “a touch of OCD”

We’ve probably all heard people jokingly or proudly describe their habit of meticulously rearranging their bookshelves or taking an incredibly long time to clean their bathroom as “a bit OCD.”

Most people have a rough idea of ​​what OCD is, but it tends to be thought of as a behavioral quirk. In fact, the condition is characterised by intrusive thoughts and compulsions that cannot be stopped, and it is debilitating for the 1-3% of the world’s population that are affected.

In this light, the “kind of OCD” joke risks trivializing illnesses as serious as schizophrenia or depression. This misuse of the phrase may reflect our ignorance about OCD. But as we explore in “New Understanding of OCD Paves the Way for New Treatments,” we are now discovering more about how OCD manifests in the brain, which is influencing how we think about the illness.

It’s true that obsessions and compulsions exist in all of us to some degree — maybe you run back into the house to make sure the front door is locked, or you can’t help but think about an upcoming stressful event. In fact, many of the symptoms of OCD seem to represent distortions of beneficial behavior. But imagine what it would be like if the intrusive thoughts and urges to act were unstoppable. That’s the hallmark of OCD.

It is becoming clear that OCD is a complex condition that involves the immune system.

Thanks to decades of research into the mechanisms underlying this disease, we now know that entire brain networks are affected, causing a significant imbalance in the neurotransmitters that transmit signals around them, and that the disease is more complex than we thought, with the immune system and gut bacteria also playing a role.

These insights into the body and brain causes of OCD are paving the way for much-needed new treatments for people who don’t respond to current first-line therapies. But what’s clear is that OCD is an incredibly distressing condition, and we’re only just beginning to address the problem. It’s time to stop kidding ourselves.
