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.
Norepinephrine transporter
Many drugs exist in the treatment of ADHD. Dextroamphetamine (Dexedrine, Dextrostat), Adderall, methylphenidate (Ritalin, Metadate, Concerta, Daytrana), and lisdexamfetamine (Vyvanse) block reabsorption of the catecholamines dopamine and norepinephrine through monoamine transporters (including NET), thereby increasing levels of these neurotransmitters in the brain. The strong selective norepinephrine reuptake inhibitor (NRI), atomoxetine (Strattera), has been approved by the U.S. Food and Drug Administration (FDA) to treat ADHD in adults. The role of the NET in ADHD is similar to how it works to ease the symptoms of depression. The NET is blockaded by atomoxetine and increases NE levels in the brain. It can work to increase one's ability to focus, decrease any impulsiveness, and lessen hyperactivity in both children and adults who suffer from ADHD.
