Does any Correlation exist between I.Q levels, Diagnosis Age & Morphological Parameters in Down Syndrome Patient?

ABSTRACT: The intellectual or mental development of children and adults with Down syndrome has often been described in terms of IQ (Intelligence Quotient) which is calculated on the basis of the various IQ tests. In the present study of Down syndrome patients from Haryana State, all the Down syndrome patients were categorized into four groups on the basis of degree of mental retardation following WHO system of classification (ICD-10, WHO 1993). Maximum number (52%) of Down syndrome cases was with moderate mental retardation. More number of cases of severe Down syndrome group could be diagnosed before six months as compared to mild and moderate group. Two ways ANOVA test was significant at 5 % level, showed association between mental level and age of diagnosis of patients. Chi-square (2) test indicated a significant association between chronological age & I.Q. levels in these patients. Delivery complications like mother had Rh incompatibility & bleeding during late pregnancy were more common in moderate & severe Down syndrome group as compared as compared to mild group. This study will be helping in evaluating the brain development & difference to the progress of patients with Down syndrome. The standardization data allows analyst to compare the scores for a particular child with those of a large sample of children of the same age, so that they can see if the child is doing better or worse than the standard of this large, given sample
