[Clinico-psychologic studies on the problem of functional psychotic deterioration in schizophrenia]

Our concept of the functional-psychotic mental deterioration of schizophrenia approximately characterizes the same point of view as Kraepelin's terminus "Dementia praecox". The first result of our psychological examination on 225 schizophrenic persons with defect psychotic symptoms was the statement of the deficit in achievement between the former school education (average IQ of the school-type) and the results of examination of intelligence during our research. The functional-psychotic mental deterioration as well appears as a decrease of memory and psychomotoric speed deficiency, furthermore as mental deconcentration and increase of psychoorganic signs in the Rorschach-Test. The psychometric results of this research were statisticly significant.
