The main part of neurological growth and development occur in the first two years especially in the first 6 months of life. Metabolic or skeletal diseases are important causes of developmental delay. Early diagnosis of deviance from the normal diagram of development in lower ages is important. Materials & Methods Specific ages and stages questionnaires (ASQ) for 6 months was completed in the health centers for 800 infants conferring for their vaccination in Isfahan and the retest was performed at 24 months of age by ASQ and then these two questionnaires were compared. Results 10.5% of the infants were delayed in at least one domain. At 24 months, 38.4% of them remained delayed; 21.1% in one domain, 9.6% in two domains, 3.8% in four domains and 3.8% in five domains. Of the children who had problem in communication, 20%; in gross motor, 25%; in fine motor, 20%; and in problem solving, 30% remained delayed. In the personal social domain, none of the delayed children at 6 months remained delayed at 24 months. Conclusion ASQ is feasible, inexpensive, easy to use and was appreciated by the parents. It can be used as a screening test for detection of developmental delay in lower ages, but its results must be followed by other standard tests or diagnostic tools.
