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.

ADHD is a neurodevelopmental disorder which is most pronounced in children. Current pharmacological treatments consist of stimulant medications (e.g. methylphenidate), non-stimulant medication (e.g. atomoxetin) and α2 agonists. These medications have a great deal of adverse effects as well as being potentially addictive. Developing alternative treatments is therefore desirable. "In vivo" studies show potential of using HR antagonists in ADHD to aid in attention and cognitive activity by elevating release of neurotransmitters such as acetylcholine and dopamine.
