Positive and negative symptoms in schizophrenia: application of Jacksonism

Factors influencing prognosis and relapse in schizophrenia were investigated systematically. The results agreed with Jacksonism. Data were collected from 166 patients who suffered relapses and were readmitted to Hospital, into seven categories from Nov 15, 1971 to Dec 31, 1974. The psychiatric symptoms were classified from A to G, positive to negative. The initial symptoms were divided into 4 groups. There was interrelation between the somatic and psychiatric symptoms; in the initial symptoms and the prognosis, courses, and psychiatric symptoms. Based on the author's results, the author suggests that an evolutional and hierarchical interpretation, which Jackson emphasized, in the correlation between brain and mind is applicable in the psychopathology of schizophrenia.
