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…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
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 undergo a scan, which lasts for approximately 2 hours and takes…
Condition: Cancer / Breast Cancer
Investigator: Sheldon Feldman
Status: Closed
The main purpose of this study is to determine the safety and tolerability of Faslodex given directly into thebreast ducts of women with invasive breast cancer or Ductal Carcinoma In Situ (DCIS). This study is for women who have been diagnosed with invasive breast cancer or DCIS. DCIS is the presence of abnormal cells inside a milk duct in the breast, and…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Yagna Pathak, PhD
Status: Closed
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).
