A population-based study of active epilepsy was conducted in 6-13-year-old mentally retarded children born between 1975 and 1986.
The population at risk comprised 48 873 children.
Ninety-eight children were identified, 35 mildly and 63 severely retarded.
The prevalence was 2.0 per 1000 ; 0.7 per 1000 for mildly and 1.3 per 1000 for severely retarded children.
Sixty-nine children had at least one additional neuroimpairment.
Cerebral palsy was found in 42 children with a majority of spastic/dystonic tetraplegias ; visual impairment was present in 24 and autism in 24.
Thirty-three children had only a mild or no gross motor disability and mild mental retardation, while 23 had IQs<20 and a very severe gross motor disability.
This study underlines the fact that active epilepsy in mentally retarded children is often associated with additional neuroimpairments, especially a combination of severe cerebral palsy and severe visual impairment.
