Associated neuropsychiatric problems in Swedish school children with mild mental retardation.

A total of 83 mildly mentally retarded children aged 13-17 years were examined. These children are considered representative of all clearly mildly mentally retarded children born in 1966-1970 and living in Göteborg, Sweden. Fifty-seven per cent of the children were suffering from a handicapping psychiatric condition. Epilepsy and male sex were found to be associated with psychiatric abnormality.
