Comparison of epidemiological studies of seizures and epilepsy in mentally retarded populations is difficult. The following factors need to be taken into Reprint requests to Dr. Richardson, Albert Einstein College of Medicine, Yeshiva University, 1300 Morris Park Avenue, Bronx, NY 10461. Dr. McLaren is with the MRC Medical Sociology Unit, Institute of Medical Sociology, Westburn Rod, Aberdeen AB9 2ZE, Scotland. This study was supported by the Foundation for Child Development, The William T. Grant Foundation, The Easter Seal Research Foundation, The National Institute of Child Health and Human Development Grant No. HD07907, and The Social Science Research Council of the United Kingdom. The authors wish to thank Professor Raymond Illsley and Gordon Horobin of the MRC for their help and support, and Drs. J. Selman and W. A. Hauser for their advice and suggestions.

N2 - The paper examines seizure histories in a 5-year cohort, age 22, who had been classified as mentally retarded during the school years in a British city. Results are examined in relation to matched comparisons, a borderline mentally retarded group, and other studies. Twenty-seven percent of the mentally retarded experienced one or more seizures. Equivalent figures for the borderline and comparison groups are 11% and 4% respectively. Within the mentally retarded population, the more severely mentally retarded more often had seizures, had them earlier and over a longer time span than the mildly retarded. Seizures are described on a year-by-year basis using both longitudinal and cross-sectional views. Prevalence studies of epilepsy in mentally retarded populations are reviewed, and problems of definition and method are discussed.
