Bleuler at English => English (The Britannica Concise) Of Explained:
Swiss psychiatrist. He is best known for his studies of schizophrenics and for introducing (1908) the term schizophrenia for the disorder previously called dementia praecox. Bleuler argued (against accepted wisdom) that schizophrenia was more than one disease, was not always incurable, and did not always progress to full dementia. He described the basic symptoms--disordered mental associations and splitting or fragmentation of the personality--but believed that many cases were not apparent. He insisted that psychosis did not need to result from organic brain damage, and could have psychological causes instead. His Textbook of Psychiatry (1916) became a standard text.
