Methods: It is a hospital-based descriptive study where hospital records of all cases diagnosed as a language delay presented to PNUSU from January 1st, 2015 to December, 31st, 2015 were analyzed. Results: Among 800 cases, DLD due to intellectual disability (ID) is the commonest type (34.4 %) followed by below average borderline intellectual (28.5 %). Risk factors study reveals that 66.7 % of studied children are males, 48.9 % of cases show a history of consanguineous marriage between parents and 20 % of studied children had a positive family history of language, speech, or learning problems. Perinatal and neonatal period risk factors appear most frequently as 54.3 %, and the predominant factor is Hyperbilirubinemia. Conclusion: Reported data reflect the magnitude of language disorders problem in Upper Egypt that necessitates special attention from multi-disciplines toward consanguineous marriage and neonatal Hyperbilirubinemia as both are the highest incidence within investigated cases.
