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.
Treatments for PTSD
Antidepressants are widely used in the treatment of PTSD and have consistently shown efficacy, though the magnitude of improvement is often modest. The most popular types of antidepressants are SSRIs, atypical antidepressants, tricyclic antidepressants (TCAs), and monoamine oxidase inhibitors (MAOs). SSRI are most often used as they are considered safer than TCAs and MAOIs. To date, only sertraline and paroxetine carry FDA approval for PTSD, though in general, all SSRIs seem similarly effective. These medications appear to be helpful across all PTSD symptoms. According to the APA Practice Guidelines, "SSRIs have proven efficacy for PTSD symptoms and related functional problems".
