Biological Factors in Mild Mental Retardation.
Costeff, H.; And Others
Developmental Medicine and Child Neurology, v25 n5 p580-87 Oct 1983
Children (N=434) with nonsyndromic mental retardation were analysed for frequency of prenatal, perinatal and infantile biological disturbances. Mildly retarded individuals of unrelated parentage, both idiopathic and familial, had a strikingly higher prevalence of disturbances than a control group of retarded individuals with consanguineous parents and of probably genetic aetiology.
