[Newly developed nomenclature (Neuroscience-based Nomenclature)]

The current nomenclature is based on clinical indications; for example, drugs used for mania and psychosis are classified as "mood stabilizers" and "antipsychotic drugs", respectively. This discrepancy between their names and indications often confuses patients and their caregivers and sometimes leads to a misunderstanding of the effects of prescribed medications. In addition, up-to-date scientific knowledge on these drugs has not been reflected in the current nomenclature. To overcome these limitations of the current nomenclature, following an initiative of the European Congress of Neuropsychopharmacology (ECNP), a taskforce for psychotropic nomenclature was established with representatives from 5 international organizations, including the Asian College of Neuropsychopharmacology (AsCNP). The mission of this taskforce is to provide a pharmacologically-driven (rather than indication-based) nomenclature, which is now referred to as Neuroscience-based Nomenclature (NbN). The NbN project has just started. Since it always takes time to change the culture, we understand the transition will likely involve some expected and unexpected responses from the field. However, we believe that such responses and feedback will surely improve the quality of the NbN, which in turn will be beneficial for clinicians, researchers, and patients as well as their caregivers.
