Obsessive-compulsive disorder and global mental health.

The discipline of global mental health has emphasized the importance of the treatment gap in mental disorders, and of addressing this gap via changes in health policy, an emphasis on human rights, and innovations such as task-shifting. Although global mental health research has focused on both common mental disorders such as depression, and serious mental disorders such as schizophrenia, it has paid relatively little attention to obsessive-compulsive and related disorders (OCRDs). Nevertheless, international collaborations have recently paid a good deal of attention to the nosology and neurobiology of OCRDs, and given the prevalence and morbidity of these conditions, further work along these lines should be encouraged. This article provides a brief overview of recent international collaborations on OCRDs, and outlines future directions for such work.
