[Minimal brain dysfunction and social class (author's transl)]

The dependence of early occuring minimal brain dysfunction on the standard of living was tested. 1355 6-15 year old patients with psychosomatic and psychiatric disorders were examined and divided into the 3 groups: "no brain dysfunction", "suspected brain dysfunction" and "brain dysfunction" (diagnosed medically). A highly significant correlation between brain dysfunction and a low socio-economic status--evaluated in terms of living conditions and the fathers occupation--was found. A similar dependence of both, early mortality and morbidity on the living standard of different groups of the population is described in the literature.
