Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Rebecca Straus Farber, MD
Status: Closed
The purpose of this study is to evaluate the differences between immune profiles of individuals remaining on Ocrelizumab/Rituximab versus those transitioning to diroximel fumarate at two years. Baseline visits for subjects transitioning to diroximel fumarate (DRF) will take place 6 months after last Ocrelizumab (OCR) or Rituximab (RTX) dose, prior to…
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Rebecca Straus Farber, MD
Status: Closed
We are currently recruiting individuals with Multiple Sclerosis (MS), first-degree family members of persons with MS, and healthy individuals to take part in our research on the effects of probiotics. Our goal is to better understand how the health of the gut microbiome influences the immune system.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Amy Rapp, PhD
Status: Closed
The goal of the project is to identify differences in learning in obsessive-compulsive disorder (OCD) by measuring the activity of the brain while participants complete computer tasks. Eligible participants will be asked questions about their medical and psychiatric history and perform tasks on a computer while an electroencephalogram (EEG) is recorded.…
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Rebecca Straus Farber, MD
Status: Closed
This study will be used to evaluate the immunologic effects of Prebiotics (soluble fiber required by beneficial bacteria), in comparison to Probiotics (beneficial bacteria), in individuals with Multiple Sclerosis (MS) and Clinically Isolated Syndrome (CIS).
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Victoria Leavitt, PhD
Status: Closed
ASPIRE is a clinical trial to investigate aspirin as a treatment to improve exercise performance in people with multiple sclerosis (MS) who experience overheating during exercise. Persons with multiple sclerosis benefit from exercise, but many avoid it because of exhaustion and overheating. This randomized controlled trial (RCT) tests aspirin as a method to…
Condition: Psychiatric Disorders / Schizophrenia
Investigator: Gaurav Patel, MD, PhD
Status: Closed
Our lab is conducting a series of research studies that investigate how specific brain regions are related to functioning in work, school, and in other social situations. As a study participant, you will be asked to complete clinical and neuropsychological assessments, an eye-tracking task, and a non-invasive MRI scan. Study participants earn between $15-50…
Condition: Psychiatric Disorders / Schizophrenia
Investigator: Guillermo Horga, MD, PhD
Status: Closed
In this study, we are trying to learn more about the symptoms of schizophrenia, specifically to learn how abnormalities in the brain may produce certain experiences that are common in patients with schizophrenia. The study involves clinical interviews, clinical chart review, computer tests, and magnetic resonance imaging (MRI) scans.
Condition: Neurological Disorders / Multiple Sclerosis
Investigator: Claire Riley, MD
Status: Closed
The purpose of this study is to see if ocrelizumab (study drug) will stabilize, or potentiallyimprove the signs and symptoms of your MS. Ocrelizumab is a type of drug called amonoclonal antibody. Monoclonal antibodies act like your bodys immune system andattach to certain cells in order to attack germs and other illnesses in your body.Ocrelizumab attaches…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Reilly Kayser, MD
Status: Closed
The Center for OCD and Related Disorders at New York State Psychiatric Institute/Columbia University Medical Center is seeking individuals aged 18+ with obsessive-compulsive disorder (OCD) to participate in a survey regarding their experiences with marijuana/cannabis. We hope this study will lead to increased understanding of how these substances affect…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
Eligible participants will be asked questions about their symptoms, complete questionnaires, and receive sessions of Cognitive-Behavioral therapy consisting of Exposure and Ritual Prevention (EX/RP) accompanied by the use of a mobile app. The purpose of this study is to assess whether the mobile app may be effective in improving symptoms of OCD.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Pablo Goldberg, M.D.
Status: Closed
The purpose of this study is to assess the effects of a single infusion of ketamine for adolescents and young adults with obsessive-compulsive disorder (OCD). Ketamine is a FDA-approved anesthetic medication that can possibly cause a rapid decrease in OCD symptoms. To be eligible to participate, patients need to have already tried at least one SRI…
