Abstract
|
|
|
Schizophrenia, which has extraordinary diverse and complex symptoms, is rather a clinical syndrome than single disease entity. With no known etiology, we have no choice but depending on symptoms manifested by the patients to establish disease identity or diagnostic classification of schizophrenia. In the early years of 20th century, a few out-standing researchers arranged characteristic symptoms of schizophrenia. The bases of those arrangement were symptom itself and the course. Since 1970´s so many psychiatrists and researchers felt keenly the necessity of operationalized diagnostic criteria in order to raise interrater reliability. So lots of diagnostic criteria were devised. But those diagnostic criteria inevitably had basic limitations such as poor construct validity.
This article reviewed representative descriptive psychopathological theories of schizophrenia chronologically. In the future by grafting descriptive psychopathology and di-verse cognitive neuroscience techniques together, we can expect more ideal theory concerning disease identity of schizophrenia.
