Light Therapy for Obsessive-compulsive Disorder (OCD)

The goal of this clinical trial is to test whether light therapy is effective for reducing symptoms in young adults with OCD and late bedtimes (1am or later). The main question\[s\] it aims to answer are: Does light therapy reduce OCD symptoms? Does light therapy advance the circadian clock? If there is a comparison group: Researchers will compare a higher dose of light therapy to a lower dose to see if dose amount affects symptom reduction. Participants will asked to: 1. Wear light therapy glasses for 1 hour each morning and complete a daily light therapy log for 5 weeks 2. Track their sleep every day with a wearable monitor and an electronic sleep diary for 5 weeks 3. Complete a 1-time assessment of sensitivity to light exposure 4. Complete self-report measures of OCD 4 times/day at baseline (2 weeks), mid-treatment (1 week), and end of treatment (1 week)

Testing Delivery Modalities of Team-Based CBT for Pediatric Anxiety in Community Health Settings.

The purpose of this study is to test how the delivery of Cognitive Behavioral Therapy (CBT) for pediatric anxiety and OCD via different methods might increase its availability and effectiveness. CBT involves teaching the patient skills to enable them to gradually come into contact with feared situations. This process of gradually approaching feared situations is called exposure. Although CBT with exposure has the best evidence for treating anxiety disorders, not all children have equal access or respond the same way to CBT. As part of this study, patients will receive weekly CBT treatment sessions involving a combination of weekly visits with an exposure coach and one visit a month with a licensed provider (e.g., social worker) who also provides weekly supervision for the exposure coach. This treatment will be delivered using one of three methods: 1) in-person (face-to-face sessions, occurring in the office and the home/community), or 2) telehealth (entirely remote sessions via web-based video conference), or 3) flexible (individualized mix of in-person and/or telehealth sessions). Eligible participants will be randomly assigned to one of these three methods. Results of this study will help determine which treatment method works best for whom. Treatment as described above will occur as part of care at partnering community care sites in Rhode Island. Providers from the following partnering community care sites will make up patient treatment teams: Blackstone Valley Community Health Care, Family Services of Rhode Island, Gateway Healthcare, Newport Mental Health, and Thrive Behavioral Health. The research study is being conducted by the Pediatric Anxiety Research Center at Brown University Health. The research team will conduct the study assessments that patients will be asked to participate in as study participants. Patients will be asked to complete assessments prior to starting treatment, at two time points during treatment, at the end of treatment, and at two timepoints 3 and 6 months following the end of treatment. Participants will be compensated for their time completing research assessments.

Neuromodulation for a Novel OCD Biomarker and Treatment

Although multiple treatments for OCD exist, slow symptom decrease, high remission, and significant side effects for some OCD patients limit their efficacy. More research into the precise neural mechanisms and linked cognitive functions in OCD is also necessary. To address both concerns, this study by Dr. Reinhart and his team will test a new, non-invasive, and well-tolerated neuromodulation method for reducing OCD symptoms, based on reward-related rhythms of the orbitofrontal cortex (OFC; a brain region responsible for reward, decision making and other crucial functions that is affected by OCD). This proposal is based on highly encouraging preliminary data in both subsyndromal and treatment-resistant populations that shows rapid reductions in OCD behaviors that last at least 1-3 months. Using high-definition transcranial alternating current stimulation (HD-tACS) guided by EEG brain wave recordings, the study will test whether repetitive modulation of relevant rhythm activity in the OFC can lead to rapid (within five days) and sustainable (up to three months) OCD symptom reduction. This research aims to increase knowledge of OCD and development of effective treatment with minimal side effects.

How Hormones and Exposure and Response Prevention (EX/RP) Affect the Brain of People With OCD

Studies show that hormones affect the brain's fear extinction network, which is relevant for therapy involving exposure and response prevention (EX/RP), a first-line treatment for obsessive compulsive disorder (OCD). This study will examine the effect of delivering EX/RP to women during different phases in their menstrual cycle to determine the effects of hormones on the fear extinction network and on their OCD symptoms.

Locating Biomarkers in OCD Through Behavioral Tasks

Subjects that have a diagnosis of OCD will participate in a clinical interview and cognitive tasks, during which they will be exposed to their individual OC stressors or will be asked to make decisions related to information value and quantity while measuring neural activity and filming facial reactions. This will assist investigators to look for biomarkers of that change. This study offers a unique opportunity to develop biomarkers for key domains of OCD, and other neuropsychiatric disorders, that are grounded in brain neurocircuitry at the individual-patient level. Subjects will participate in a clinical interview (Day 1), and then tasks+EEG (Day 2). Day 1 will be 4 hours or less, and Day 2 will be 2.5 hours or less.

Digital Coach to Support Exposure Therapy Homework for Anxious Youth

This study is testing a digital tool called BraveBot for young people who are receiving cognitive behavioral therapy (CBT) for anxiety, OCD, or related problems. BraveBot is a computer program, not a person. It talks with youth through their phone or computer while they do "face-your-fears"-style exposure therapy homework that their therapist has assigned. Sometimes an exposure is done with BraveBot's real-time coaching, and sometimes on their own; after each exposure, youth answer a few short questions about how it went. Rather than dividing participants into separate groups, the study randomizes each individual exposure homework assignment. Every time a young person opens an eligible exposure, the system makes a 1:1 random assignment deciding whether that exposure is completed with BraveBot's support or independently (self-guided). The main goal is to learn whether using BraveBot helps youth understand their exposure assignments better, put in more effort, stick with exposures when they are hard, feel more capable, and find exposures more helpful in "fighting back" against anxiety. The study also examines whether BraveBot increases the likelihood that assigned exposures are completed, and explores effects on anxiety symptoms and how safe, easy to use, and useful BraveBot feels for youth, their therapists, and parents. BraveBot does not replace the therapist, diagnose, or design exposures; it only supports the homework the clinician has assigned, and is used under clinician oversight. A built-in safety system can detect possible risk-related language, pause the session, show crisis resources (such as 988), and notify the treating clinician. The study is conducted within routine outpatient psychology clinics at Mass General Brigham. Up to 40 youth ages 12-22 will take part.

Open-Label Psilocybin Study in Transdiagnostic Population

The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significant symptom reduction and functional improvement from baseline symptom measurements (Visit 3) to 1-week (Visit 7), 4-weeks (Visit 8), and 6-weeks (Visit 9) post dosing. The investigators will recruit individuals with mood, anxiety, trauma, addictive, or related symptomatology, and who have functional impairment associated with these symptoms. A DSM-5 diagnosis is not required (nor is it an exclusion). The investigators will allow for comorbidity and only exclude based on psychological and physiological safety considerations. Critically, this approach will allow us to assess the tolerability of our interventions in individuals who would typically be excluded from efficacy studies due to various comorbid DSM-5 conditions. The investigators will employ an open-label study where participants will be given one dose of oral psilocybin 25mg. The investigators will also have follow-up visits at 1, 4, and 6 weeks and an optional long-term follow-up at 3, 6, and 12 months.

Neurostimulation Versus Therapy for Problems With Emotions

The primary goal of this clinical trial is to evaluate the unique neural and behavioral effects of a one-session training combining emotion regulation skills training, with excitatory repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (dlPFC). The secondary aim is to identify key changes in the emotion regulation neural network following the combined intervention versus each of the components alone. The third aim is to explore personalized biomarkers for response to emotion regulation training. Participants will undergo brain imaging while engaging in an emotional regulation task. Participants will be randomly assigned to learn one of two emotion regulation skills. Participants will be reminded of recent stressors and will undergo different types of neurostimulation, targeted using fMRI (functional MRI) results. Participants who may practice their emotion regulation skills during neurostimulation in a one-time session. Following this training, participants will undergo another fMRI and an exit interview to assess for immediate neural and behavioral changes. Measures of emotion regulation will be assessed at a one week and a one month follow up visit.

Objective Characterizatoion of Repetitive Behaviors

Introduction: Repetitive behaviors (RB) constitute a broad range of symptoms across different psychiatric/neurologic disorders. The most famous are stereotypies (found in autism), compulsions (found in obsessive-compulsive-disorder, OCD) and tics (found in Gilles de la Tourette syndrome, GTS). For some patients, it is sometime difficult to distinguish the nature of the repetitive behaviors presented, however this distinction is crucial in order to chose the appropriate treatment. Aim: In our study, the investigators will try to define electrophysiological and accelerometric marker of both OCD and tics to allow objective distinction between both tics and compulsions. Method: Subjects: Both OCD and GTS patients will be recruited, 25 patients in each group. Protocol: our study protocol will involve two step: a step in laboratory, another step at patient home. * first step: both patients group will be recorded through a high density EEG and a portative EEG while doing a task of symptom provocation. Then they will get an anatomical MRI for source recontruction. Finally, the patients will have to mimic their symptom while wearing an accelerometer (a smartwatch). * second step: both patient groups will be recorded at home through a portative EEG while tagging their symptom through a smartwatch (also used for accelerometry). After the recording, the patients will keep the smartwatch for 2 weeks, still tagging their sympoms (compulsions or tics).

Discovering Factors in the Clinical Study Journey of Patients With OCD

This research aims to collect comprehensive data on the clinical trial experience of OCD patients. Its goal is to identify the factors that limit patients' ability to join or complete a trial successfully. Clinical trial participation often favors specific demographic groups, and limited research exists on the impact of trial attributes on participation. Therefore, this study aims to analyze data from various demographic groups and identify any recurring trends that could provide valuable insights for future OCD patients.
