BACKGROUND
Context- Congenital hypothyroidism is an important cause of preventable mental retardation in children. Since, neonatal screening is not done routinely in India, many cases are diagnosed late. Earlier, the diagnosis and initiation of treatment, better will be the outcome.
The aim of the study is to assess the effect of time of onset of treatment in intellectual and scholastic performances in children with congenital hypothyroidism.
MATERIALS AND METHODS
Children were classified into 3 groups. Group 1 were diagnosed and treatment initiated within one month of birth. Group 2, between 1 and 6 months and group 3 after 6 months. General intelligence and IQ were assessed by Malin’s intelligence scale for Indian children. Scholastic performance were evaluated by academic evaluation scale for slow learners and ADHD were diagnosed by DSM-IV criteria.
Settings and Design- The study was done in the Paediatric Endocrinology Clinic of Institute of Maternal and Child Health, Department of Paediatrics, Government Medical College, Kozhikode. Study population included children of age group 6-9 years with congenital hypothyroidism.
Statistical Methods Used- Statistical analysis was done with SPSS software version 16. The statistical analysis was done by ANOVA test.
RESULTS
IQ and intellectual outcomes were better in group 1 where treatment was initiated within one month. Similarly, poor academic abilities and increased incidence of ADHD were noted in children in whom diagnosis was made late.
CONCLUSION
Later the diagnosis more will be the intellectual and scholastic backwardness in children underscoring the importance of universal newborn screening.
