The authors analyze both the demographic situation in Russia during the past years and its perspective. A number of patients with paranoid schizophrenia and with schizophrenia on the whole (all forms of disease) was estimated for the period of the coming 15 years (till 2011 yr.). The level of the patients' detection in some Russian regions was estimated by means of comparison of the calculated number of the patients (according to tables of incidence) and actually known during the same period. The proportion of registered schizophrenic patients was up to 95.7% from calculated data in Moscow, while in other regions this index was not more than 50%. A low detection of the schizophrenic patients was explained by both specificity of the organization of psychiatric care in the regions, a shortage of psychiatrists as well as by other factors.
