Dementia praecox (a "premature dementia" or "precocious madness") refers to a chronic, deteriorating psychotic disorder characterized by rapid cognitive disintegration, usually beginning in the late teens or early adulthood. It is a term first used in 1891 in this Latin form by Arnold Pick (1851–1924), a professor of psychiatry at the German branch of Charles University in Prague. His brief clinical report described the case of a person with a psychotic disorder resembling hebephrenia (see below). It was popularized by German psychiatrist Emil Kraepelin (1856–1926) in 1893, 1896 and 1899 in his first detailed textbook descriptions of a condition that would eventually be reframed into a substantially different disease concept and relabeled as schizophrenia.
