An overview of Indian research in obsessive compulsive disorder

Obsessive-compulsive disorder (OCD) was considered a relatively rare disorder until about two decades ago. Since then, considerable advance has been made in understanding the various aspects of OCD that include epidemiology, clinical features, comorbidity, biology and treatment. In the last one decade, there has also been interest in a group of related disorders called obsessive-compulsive spectrum disorders. There is substantial research from India on various aspects of OCD, particularly from the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore. We attempt to review all the relevant Indian data on OCD.
