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.
Oppositional defiant disorder
Psychopharmacological treatment is the use of prescribed medication in managing oppositional defiant disorder. Prescribed medication to control ODD include mood stabilizers, antipsychotics, and stimulants. In two controlled randomized trials, it was found that between administered lithium and the placebo group, administering lithium decreased aggression in children with conduct disorder in a safe manner. However, in a third study it found the treatment of lithium over a period of two weeks invalid. Other drugs seen in studies include haloperidol, thioridazine, and methylphenidate which also is effective in treating ADHD, as it is a common comorbidity.
