He revised and expanded his schizophrenia concept in his seminal study of 1911, Dementia Praecox, oder Gruppe der Schizophrenien (Dementia Praecox, or Group of Schizophrenias), which was only translated into English in 1950 (by Joseph Zinkin). Like Kraepelin, Bleuler argued that dementia praecox, or "the schizophrenias," was fundamentally a physical disease process characterized by exacerbations and remissions. No one was ever completely "cured" of schizophrenia—there was always some sort of lasting cognitive weakness or defect that was manifest in behavior.
