Clinico-pathological investigation of borderline schizophrenia (42 women) and cyclothymia (22 women) with concomitant disorders in menstrual function was performed in a regional out-patient gynecological department. Major types of the course of mild psychopathology were identified which involve the endocrine gynecological dysfunction. Functional disorders of the menstrual cycle are seen as a class of numerous somatic signs masking the psychopathology in its proper sense in mental diseases and emerging at the edge of "soft" endogenous mental disorder. The authors postulate that the central nervous system regions responsible for child birth are involved into these forms of mental pathology. The issues of differentiating these ailments involving gynecological dysfunction from the true endocrine-gynecological pathology are discussed.
