The etiology of severe mental retardation has not previously been studied in Jordan. In a group of 203 mainly severely mentally retarded children born 1975-1985, we found the etiology to be related to two main factors: (1) sequele from high perinatal morbidity or meningitis in infancy leading to a combination of severe mental retardation and cerebral palsy; (2) a high degree of intermarriage and a high frequency of retarded siblings indicating that genetic causes of MR are common. The results underscore the importance of further development of antenatal and perinatal care, especially for poor people and the need of genetic counselling.

D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults.

Scores below 67 are in the disabled range.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
