Human genetics as an approach to the classification of mental diseases.

摘要: If we try to arrange the many patterns of mental disease as regards underlying heredological trends it is possible develop a system disposed "natural series". In our tentative one, which combines eugenic and dynamic criteria chiefly, tried assemble 24 separate clinical conditions into 5 major groups: I - Psychoses with toxi-infectious diseases (4 entries); II accidental intoxications (2 entries) ; III Constitutional endogenous psychoses (7 IV Marginal states V Defective by local or abiotrophic brain lesions entries). Among listed under are Kleist's marginal "degenerative" psychoses, frequent indeed in psychiatric practice, so require their consideration.
