Among 176 depressive symptoms informative symptomological combinations were differentiated (by means of mathematical methods) which characterize the neurotic and hypopsychotic depressions and provide a high percent of diagnosis of these conditions by a computer. An additional group of patients was distinguished which occupied a sort of intermediate position between the two mentioned categories. It was found, incidentally, that the vegetative syndromes within the framework of depressions have a rather small informative-diagnostic importance.
