Abstract
Anemia is usually defined as a decrease in the amount of red blood cells (RBCs) or hemoglobin in the blood .
Pediatric Anemia is defined as a hemoglobin (Hgb) concentration or red blood cell (RBC) mass less than the 5th percentile for age .
Chronic anemia may result in behavioral disturbances in children as a direct result of impaired neurological development in infants, and reduced scholastic performance in children of school age .
Our aim in this study was assessment of IQ at different types of anemia in Children including ( Microcytic hypochromic anemia and Normocytic normochromic anemia) and in healthy controls.
This study was conducted at outpatient clinic of the Hematology Unit at El-Minia University Hospital in Egypt during the period from September 2015 to April 2016.

group A had 24 children with microcytic hypochromic anemia (MCV<80) theses children were further divided into 2 subgroups:
group A1 had 14 children with Iron deficiency anemia (serum ferritin less than 10 μg/L ).
group A2 had 10 children with β-thalassemia major (Hb electrophoresis).
2) group B had 20 chil¬dren with normocytic normochromic anemia (MCV 80–100).
3) group C the control group of 25 apparntly healthy children of matched age & gender to both groups A & B
The included children in this study were subjected to history taking, clinical examination as well as laboratory investigations including complete blood count, serum ferritin & Hb electrophoresis. All the patients and controls were subjected to psychometric assessment using the Arabic version of the Wechsler Intelligence Scale for Children–Third Edition.
