Nosologic homotypes are psychiatric populations identical in psychopathological symptoms and assigned to the same position in a “nosologic matrix” based on form of onset, course, outcome, polarity and totality of clinical manifestations. The term was coined by Thomas A. Ban, while searching for psychiatric populations more suitable for neuropsychopharmacological and molecular genetic research than those identified by psychiatric diagnoses. It was introduced, in 2002, in his chapter on “Neuropsychopharmacology: the interface between genes and psychiatric nosology”, published in Bernard Lerer’s “Pharmacogenetics of Psychotropic Drugs” (Ban 2002, 2007).
