BACKGROUND: Psychogenic psychonosema means a group ofphrenoblabia caused under the conditions of severe and continuouspsychic trauma, which often has goad prognosis and can achievecomplete alleviation. Mental stimulation is considered as the mostbasic reason. But it is curt not be differentiated clinically becauseindividuals have different sense and tolerance against external stim-ulation and intensity of psychological stimulation itself is up to therelationship between accidence and interests of individuals, so it cannot be calculated. In addition, patients themselves have the potentialpossibility of attack of schizophrenia. Then we should think it iscaused because inducing schizophrenia not because psychogenicpsychonosema.
