Objective

Central Nervous system (CNS) malformations are one of the most important causes of global developmental delay (GDD) in Children. About one percent of infants with GDD have an inherited metabolic disorder and 3-10 percent have a chromosomal disorder. This study aimed to survey the frequency of brain structural anomalies and their subtypes among the variety of etiologic factors in children with GDD in our patients.

Materials & Methods

This study used the results of neuroimaging studies [unenhanced brain Magnetic Resonance Imaging (MRI)] of all children who had been referred for evaluation of GDD to outpatient Clinic of Pediatric neurology at Children’s Medical Center affiliated to Tehran University of Medical Science between September 2009 and September 2010.

Results

In this study, unenhanced brain MRI was performed on 405 children, of which

80 cases (20 percent) had brain structural anomalies. In 8.7 percent of the cases, previous history of brain structural disorders existed in other children of the family and 20 percent of mothers had inadequate consumption of folate during pregnancy.

Conclusion

Based on the results of this study, unenhanced cranial MRI seems to be a fundamental part of evaluation in all children with GDD. Adequate folate consumption as prophylaxis as well as genetic counseling can be worthy for high-risk mothers who have previous history of CNS anomaly or miscarriage to avoid repeated CNS anomalies in their next pregnancies.
