Objective: The aim of this work was to evaluate receptive and expressive language skills in children with congenital hypothyroidism receiving early hormonal replacement treatment before the age of 3 months and to identify any subtle areas of weaknesses in their language development to check the necessity for future language intervention. Patients and Methods: The study was conducted on 30 hypothyroid children receiving hormonal replacement. They were subdivided into group I (5-8 years 11 months; 12 cases) and group II (9-12 years 11 months; 18 cases). All patients were subjected to a protocol of assessment applied in the Diabetes, Endocrine and Metabolism Pediatric Unit (DEMPU) and evaluation of language skills by the REAL scale. Results: The younger group reached average Arabic language scores, while the older group showed moderate language delay. Conclusion: Early replacement therapy supports language development in young children. However, longitudinal and follow-up studies are required to identify difficulties presenting at older ages that may affect children in the academic settings.
