Yale Psychiatry is the largest provider of psychiatric services in Connecticut, and the top National Institutes of Health-supported Department of Psychiatry in the United States. We are dedicated to adding to the body of knowledge in the field, and improving treatments for psychiatric disorders that span all ages. This includes helping people cope with major life events or medical illnesses, behavioral problems associated with personality disorder or addiction, mood and psychotic disorders, and dementia. Yale investigators have pioneered new treatments for nearly every psychiatric disorder. Our research programs have produced breakthroughs in areas as diverse as molecular neuroscience, genetics, translational neuroscience, neuroimaging, psychopharmacology, psychotherapy, rehabilitation, health services, forensic psychiatry, epidemiology, and health policy. Today, our clinicians are at the forefront of social, pharmacological, psychological, rehabilitative, and neurostimulation treatments. Through clinical trials, our interventional psychiatry service delivers high-impact treatments, including ECT (electroconvulsive therapy) and ketamine, for patients with treatment-resistant symptoms of depression. Our clinical programs are interwoven with our research efforts. We host programs that specialize in the major mental diseases and substance abuse treatment at three major institutions: Connecticut Mental Health Center, the Veterans Affairs Connecticut Healthcare System, and the Yale New Haven Psychiatric Hospital. We also provide increased psychiatry support for Smilow Cancer Hospital in areas such as smoking cessation.
