Anxiety Disorders Clinic

The Anxiety Disorders Clinic (ADC) was established in 1982 to study the diagnosis, pathophysiology, and treatment of anxiety disorders. The clinic now includes programs in obsessive-compulsive disorder (OCD), posttraumatic stress disorder and related traumatic conditions (PTSD and Trauma program), social anxiety disorder, adult separation anxiety disorder, the Hispanic Treatment Program, and anxiety and depression in primary care and other medical specialty patients. Studies include effectiveness trials in community settings, efficacy trials in tertiary care settings, biological studies (e.g., brain imaging studies, translational studies), and epidemiological and health services research.

Our mission is to improve the outcome of our patients by developing and studying new therapeutic strategies, elucidating the brain mechanisms underlying their symptoms, and disseminating evidence-based practices to clinicians and patients. We are examining pharmacotherapy, psychotherapy (cognitive-behavioral therapy, interpersonal therapy, problem-solving therapy, motivational interviewing, brief supportive therapy, relaxation therapy), and complementary medicine approaches. In collaboration with colleagues at Columbia University and the New York Psychiatric Institute, we conduct brain imaging studies using a range of techniques (positron emission tomography, magnetic resonance spectroscopy, functional magnetic resonance imaging). We also conduct epidemiological and services research. For more information check the links below.
