Rorschach thought disorders and schizophrenia spectrum

This article intends to understand how well the different typologies of Rorschach thought disorders appear in psychiatric disturbances belonging to schizophrenia spectrum disorders: schizophrenia in general, paranoid schizophrenia, schizoaffective disorder and schizotypal disorder. Beginning from the analysis of some works about Thought Disorder Index (TDI), an important index detecting various forms of pathological thinking, 4 particular Rorschach thought disorders, and their respective diagnostic implications, are considered: confabulatory thought, contaminated thought, paleologic or primitive thought and combinatory thought. Rorschach confabulatory thought consists of those responses with an exaggerated elaboration degree that move away the subject from the perceptual reality or that approach him overly from it, depending on the typologies of confabulation. Formerly this phenomenon was considered exclusive of schizophrenia, today there are conflicting ideas with regard to that. Contami-nated thought represents one of most serious Rorschach phenomena, and may be considered a schizophrenia pathognomonic sign. Paleologic or primitive thought should be a rather reliable index of schizophrenia too, because is connected to primitive forms of reasoning that violate the formal logic rules, whereas in the combinatory thought diagnostic specificity results more intricate than other typologies of thought disorder.
