title: The quest for the etiology of mental disorders.
abstract: The evidence for the etiological basis of mental disorders is insufficient and contradictory. Such a situation has at least partly arisen due to the inherent heterogeneity within the various clinical diagnostic categories. Syndrome sub-categorization employing biological variables is suggested as a first step in order to achieve etiological homogeneity.
