This early-phase study at Johns Hopkins University is testing whether psilocybin, the active compound in magic mushrooms, can safely help people with obsessive-compulsive disorder (OCD). Thirty-five adults with moderate to severe OCD who have already tried other treatments will r…

This small early-phase study is testing whether psilocybin, the active ingredient in magic mushrooms, combined with supportive therapy can safely help people with obsessive-compulsive disorder (OCD) that hasn't responded to standard treatments. Ten adults with treatment-resistant…

This study explores whether a new type of group therapy, based on Eastern cultural practices, can help people with anxiety disorders. Researchers will enroll 60 participants aged 15 to 55 to test the therapy's effects on anxiety symptoms. The goal is to see if this approach is bo…

This study tests whether tolcapone, a drug used for Parkinson's disease, can reduce symptoms of obsessive-compulsive disorder (OCD) in adults. About 49 people with moderate to severe OCD will receive either tolcapone or a placebo. The main goal is to see if the drug safely lowers…

This study tests a therapy called RETELL that helps people with severe mental illness explore and reshape their life stories. The goal is to improve personal recovery, quality of life, and identity. Twenty adults with conditions like schizophrenia, bipolar disorder, or PTSD will …

This early-stage study is testing whether repeated doses of psilocybin, the active ingredient in magic mushrooms, can reduce symptoms of obsessive-compulsive disorder (OCD). Twenty-eight adults with moderate-to-severe OCD who have not responded to standard treatments will receive…

This study tests whether a short, intensive course of cognitive behavioral therapy (CBT) over 2 weeks works better than the usual weekly sessions over 6 months for people with anxiety disorders. 120 adults with conditions like panic disorder, OCD, or PTSD will be randomly assigne…

This study planned to see if using virtual reality (VR) before a brain stimulation treatment called TMS could help people with OCD feel more comfortable. It was designed for adults already approved for TMS. However, the study was withdrawn before any participants were enrolled, s…

This study tests whether a single type of cognitive-behavioral therapy (CBT) can work for several anxiety disorders, compared to therapies designed for each specific disorder. About 76 adults with panic disorder, generalized anxiety, social anxiety, OCD, or PTSD will participate.…

This study looks at whether unlicensed professionals can successfully provide cognitive behavioral therapy (CBT) to patients in a general hospital. It includes 250 adults with conditions like anxiety, depression, OCD, and PTSD. The goal is to see if this approach improves psychol…

This study tests whether a gentle electrical current applied to the scalp (tDCS) can reduce obsessive-compulsive disorder (OCD) symptoms in people who haven't gotten better with standard therapy. 43 adults with severe, long-lasting OCD will receive either real or fake stimulation…

This study tests whether the anti-inflammatory drug celecoxib (Celebrex) can reduce obsessive-compulsive disorder (OCD) symptoms in adults who are already on medication but still struggling. Researchers will use brain scans and blood tests to measure inflammation and see if it pr…

Researchers are sequencing the gut microbiomes of people with a wide range of conditions, from autism and Alzheimer's to Crohn's disease and multiple sclerosis, to see whether bacterial patterns differ by disease. The study also enrolls healthy participants for comparison. By mat…

Researchers at Baylor College of Medicine are studying how brain activity and visible behaviors, like head movements, facial expressions, and voice tone, change during tasks that trigger OCD symptoms. Adults with OCD and healthy volunteers will complete tasks that provoke distres…

This study is testing whether functional MRI brain scans can predict and track how well children and teens with obsessive-compulsive disorder (OCD) respond to a type of therapy called Exposure and Response Prevention (ERP). Thirty participants aged 10 to 17 will receive 14 weekly…

This study looks at brain activity in people already receiving deep brain stimulation (DBS) for severe obsessive-compulsive disorder (OCD). Researchers will collect recordings from the implanted device to see how brain signals relate to OCD symptoms. The goal is to better underst…

This study was designed to test the safety and feasibility of a focused ultrasound device called Exablate Neuro with a new Echo-Focusing feature for people with treatment-resistant brain disorders like essential tremor or depression. However, the trial was withdrawn before enroll…

This early study tests an adaptive deep brain stimulation (aDBS) system in 2 people with severe, treatment-resistant OCD. The device records brain signals to identify patterns linked to OCD distress and stimulation side effects. The goal is not to treat OCD now, but to gather dat…

This study tests an adaptive deep brain stimulation (aDBS) system in just 3 people with severe, treatment-resistant OCD. The device is implanted in the brain and chest, and it aims to detect brain signals linked to OCD distress and adjust stimulation automatically. The main goal …

This study looks at 60 people with obsessive-compulsive disorder (OCD) who either respond well to medication, respond to brain stimulation, or don't respond to either. Researchers will take blood samples and turn them into nerve cells in the lab to study how these cells react to …
