ABSTRACT
S. Freud's Schreber text agrees with E. Kraepelin's separating dementia praecox from paranoia, and, although it follows G. Weber's diagnosis of classical paranoia, it also recognizes traits of Kraepelin's dementia paranoides in D. Schreber. This chapter argues that Freud accepted Kraepelin's new nosological distinctions, but not his aetiology, and that Kraepelin, for his part, rejected Freud's Schreber text aetiology. Freud's Schreber text follows Kraepelin in distinguishing paranoia and dementia praecox. In fact, Freud prefers the name paraphrenia for dementia praecox, since it is related to paranoia and recalls Hecker's hebephrenia. While Freud follows Kraepelin on classificatory division, Kraepelin's Lehrbuch does not return the compliment regarding Freud's psychogenic aetiology. In particular, the eighth edition dismisses Freud's Schreber text aetiology of paranoia. In relation to Freud's conception of obsessional neurosis, Kraepelin finds the notion that affect can attach itself to new ideas, and turn them into compulsive ideas, not only unproved, but most improbable.
