Abstract Disclosure: V. leal: None. V. Alvarez: None. S.S. Awadalla: None. Growth hormone (GH) is necessary for longitudinal growth and also has multiple other functions including neurologic development. Cognitive function in children with idiopathic isolated growth hormone deficiency (IGHD) has been poorly studied. This study aims to prospectively investigate cognitive capacity in children with IGHD.Cognitive function of 10 children with IGHD (peak GH <10 μg/L) was studied using Wechsler Intelligence Scales for Children IV: Intelligence Quotient, Verbal Comprehension Index, Perceptual Reasoning Index, and Working Memory and Processing Speed Indices.6 females and 4 males were included , Age was 10.04 ±2.01 years (M± DS) , height SDS was -1.86 ±0.19 . The IQ was 100.6 ±8.5, Verbal Comprehension was 99.3 ±8.5, Perceptual Reasoning was 102.5 ±9.1, Working Memory was 99.9 ±9.8, and Processing Speed was 98.9 ±13.1. Using Spearman correlation test ; a moderate positive correlation was observed between the GH peak and the intellectual coefficient IQ and peak GH: r=0.45, p=0.18, Perceptual reasoning and GH: r=0.43, p=0.2 without a statistical significance probably because of the sample size. In conclusion; The overall IQ score fell within the normal range, with lower scores in processing speed and working memory. These findings underscore the importance of considering not only the impact on linear growth but also on cognitive development when addressing growth hormone deficiency in the pediatric population Presentation: 6/3/2024
