Obsessive–compulsive disorder
A form of psychotherapy called "cognitive behavioral therapy" (CBT) and psychotropic medications are first-line treatments for OCD. Other forms of psychotherapy, such as psychodynamic and psychoanalysis may help in managing some aspects of the disorder, but in 2007 the American Psychiatric Association (APA) noted a lack of controlled studies showing their effectiveness "in dealing with the core symptoms of OCD". The fact that many individuals do not seek treatment may be due in part to stigma associated with OCD.
Wayne Goodman
Goodman was one of the first investigators to test and establish the efficacy of Selective Serotonin Reuptake Inhibitors (SSRIs) in OCD and show their comparative advantage over other antidepressant medications. He also developed the use of adjunctive antipsychotic medications in SSRI-resistant OCD and found that patients with comorbid tic disorders are most likely to respond to this combination.
