Abstract

Association on Mental Deficiency (AAMD).The concept of mild retardation is quantitative and embraces, using conventional standards, some 2 20, of the population in addition to the 0 4%' who are even less gifted.Not all of this considerable population is in receipt of special services, even at school age; but prospects for training for skilled employment and independent social adaptation tend to be limited.Fortunately, the AAMD has omitted from the revised classification of mental handicap' the term "borderline mental retardation," but this is still in common use and embraces much of the "dull normal" stream.It seems contrary to the general sense of the leading article thus arbitrarily to exclude any causal role in mental retardation to mal- nutrition when this can admittedly cause some deficiency in the developing brain.It would seem more reasonable in the present state of science to keep an open mind on this question and to view it as one of the many possible modes of operation of the impact of adverse social and economic factors among under- privileged groups and disadvantaged classes.
