[Possibilities of the clinical comparison of diseases with a hereditary burden in the descendant generation using the model of "parents-children" ill with schizophrenia].

A special statistic method of confrontation of diseases with aggravation hereditary in the group "parents - children" is proposed. This method can be used under clinical formalization of the diseases. It is shown on a model group parents - children (118 pairs) suffering with schizophrenia, that statistical confrontation makes possible to work out group and individual prognoses in the descending generation. It is found that invariability in the descending generation is provided by a small number of stable indices, other symptoms being variable. Statistic description of the disease symptoms in the descending generation is of interest for planning genetic interpretation.
