Compulsive hoarding
Obsessive-compulsive disorders are treated with various serotonergic antidepressants including the tricyclic antidepressant clomipramine and various SSRI medications. With existing drug therapy, OCD symptoms can be controlled, but not cured. Several of these compounds (including paroxetine, which has an FDA indication) have been tested successfully in conjunction with OCD hoarding.
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.
