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.
Marble burying
Critics also point out that the marble burying test reacts to two types of drugs the SSRIs and benzodiazepines. Benzodiazepines have been shown to have no effect on patients suffering from OCD. If the test measured OCD then benzodiazepines would not affect rodent behavior.
