[Clinical patterns in the development of hypochondriac disorders within the framework of different mental illnesses].

The authors have examined 106 patients with hypochondriac states developing in the presence of various mental diseases. The patients are divided into three nosological groups: psychogenic, exogenic-organic, and endogenic. Variants of the hypochondriac syndrome occurring in each group of the disease are described. Characteristics of the time-course of hypochondriac symptomatology and the stages of the formation of hypochondriac disturbances in relation to their classification with one or another nosological group are outlined.
