    Severe mental retardation (developmental quotient (DQ)<50) was investigated in 1303 children from 2 to 24 months of age, born during 1984-87 in four population groups representing different socioeconomic levels in and around Lahore, Pakistan.

    The incidence per 1000 live births was 22 in the periurban slum, 9 in the urban slum, 7 in the village and 4 in the upper middle class group.

    The aetiology was prenatal in 79%, perinatal in 14% and untraceable in 7% of cases.

    Down's syndrome was the most common cause of severe mental retardation (36%). Impairments were studied at 2 years of age.

    Impairment of language was present in all, while locomotor dysfunction was seen in 89% of cases.

    Epilepsy and cerebral palsy were each present in 22% of cases.

    Mortality among these severely mentally retarded children was 36%.
