We are doing this study because we want to find out if MRI brain scans alone is better or worse than MRI brain scans plus preventative brain radiation for patients with small lung cancer. The usual approach for patients with small cell lung cancer is prophylactic…
The purpose of this study is to compare any good and bad effects of avoiding the hippocampus during whole brain radiation to the usual whole-brain radiation. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-…
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…
The purpose of this study is to obtain information on the safety and effectiveness of NovoTTF-100M (study device) in subjects with brain metastases (tumors) as a result of non-small cell lung cancer (NSCLC).
The Center for OCD Research at Columbia University Irving Medical Center is seeking individuals with obsessive-compulsive disorder (OCD) to participate in a research study, at no cost to you. This study is investigating the medicinal effects of nabilone for OCD symptoms. Nabilone is a synthetic form of tetrahydrocannabinol (THC), which is one of the active…
This study is investigating how the brains of people with OCD may change with treatment. The study uses Magnetic Resonance Imaging (MRI) to scan the brain, and the treatment used is a form of Cognitive-Behavioral therapy consisting of Exposure and Ritual Prevention (EX/RP). Participants will…
The purpose of this pilot research study is to test whether certain components of the marijuana plant, known as "cannabinoids", may help to reduce symptoms in patients with OCD. Specifically, patients enrolled in the study will smoke marijuana containing different concentrations of 2 different cannabinoids, THC and CBD. Both of these agents act on the…
The study aims to assess the impact of repetitive transcranial magnetic stimulation (rTMS) on brain imaging and neurophysiological measures in patients with Obsessive-Compulsive Disorder (OCD).
