of other countries, as the World Health Organization Pilot Study on Schizophrenia reported in 1973. The city with the highest prevalence of schizophrenia in the world was Moscow. In particular, the scope was widened by sluggish schizophrenia because according to Snezhnevsky and his colleagues, patients with this diagnosis were capable of functioning almost normally in the social sense. Their symptoms could be like those of a neurosis or could assume a paranoid character. The patients with paranoid symptoms retained some insight into their condition but overestimated their own significance and could manifest grandiose ideas of reforming society. Thereby, sluggish schizophrenia could have such symptoms as "reform delusions", "perseverance", and "struggle for the truth". As Viktor Styazhkin reported, Snezhnevsky diagnosed a reformation delusion for every case when a patient "develops a new principle of human knowledge, drafts an academy of human happiness, and many other projects for the benefit of mankind". In the 1960s and 1970s, theories, which contained ideas about reforming society and struggling for truth, and religious convictions were not referred to delusional paranoid disorders in practically all foreign classifications, but Soviet psychiatry, proceeding from ideological conceptions, referred critique of the political system and proposals to reform this system to the delusional construct. Diagnostic approaches of conception of sluggish schizophrenia and paranoiac states with delusion of reformism were used only in the Soviet Union and several Eastern European countries. On the covert orders of the KGB, thousands of social and political reformers—Soviet "dissidents"—were incarcerated in mental hospitals after being labelled with diagnoses of "sluggish schizophrenia", a disease fabricated by Snezhnevsky and "Moscow school" of psychiatry. American psychiatrist Alan A. Stone stated that Western criticism of Soviet psychiatry aimed at Snezhnevsky personally, because he was essentially responsible for the Soviet concept of schizophrenia with a "sluggish type" manifestation by "reformerism" including other symptoms. One can readily apply this diagnostic scheme to dissenters. Snezhnevsky was long attacked in the West as an exemplar of psychiatric abuse in the USSR. The leading critics implied that Snezhnevsky had designed the Soviet model of schizophrenia and this diagnosis to make political dissent into a mental disease. He was charged with cynically developing a system of diagnosis which could be bent for political purposes, and he himself diagnosed or was involved in a series of famous dissident cases, and, in dozens of cases, he personally signed a commission decision on legal insanity of mentally healthy
