Insights
Children with type 1 diabetes show lower verbal and full intelligence quotients compared to healthy peers. High glycosylated hemoglobin levels are linked to poorer cognitive function in these children.
Area of Science:
- Pediatric Endocrinology
- Neuropsychology
- Metabolic Disorders
Context:
- Type 1 diabetes (T1D) is a chronic condition affecting children.
- Cognitive function is crucial for development and academic success.
- Understanding T1D's impact on cognition is vital for early intervention.
Purpose:
- To assess cognitive function changes in children with T1D.
- To identify factors influencing cognitive performance in pediatric T1D.
- To compare cognitive abilities between T1D children and healthy controls.
Summary:
- Children with T1D exhibited significantly lower verbal and full intelligence quotients (IQ) than controls.
- Specific verbal sub-test scores (knowledge, category, comprehension, arithmetics, vocabulary) were reduced in the T1D group.
- Elevated glycosylated hemoglobin (HbA1c) levels correlated negatively with full, verbal, and operational IQ in children with T1D.
Impact:
- Type 1 diabetes may adversely affect children's verbal intelligence and overall cognitive function.
- Glycosylated hemoglobin levels emerge as a potential independent risk factor for cognitive deficits in pediatric T1D.
- Findings highlight the importance of glycemic control for preserving cognitive development in children with T1D.
Objective:
To study the changes in cognitive function of children with type 1 diabetes and explore the possible factors influencing cognitive function.
Methods:
Thirty-two children with type 1 diabetes (disease course equal to or more than one year) and aged from 6 to 16 years, were enrolled in this study. Cognitive function was evaluated by the Chinese Wechsler Intelligence Scale. Factors influencing cognitive function were investigated using multiple regression analysis. Thirty-two age- and gender-matched healthy children served as the control group.
Results:
Verbal intelligence quotient in the diabetic group was significantly lower than in the control group (97±15 vs 118±13; P<0.01). Full intelligence quotient in the diabetic group was also lower than in the control group (99±15 vs 113±12; P<0.01). In the verbal scale test, a sub-test of the Wechsler Intelligence Scale, scores in knowledge, category, comprehension, arithmetics and vocabulary scale in the diabetic group were significantly lower than in the control group (P<0.01). Multiple regression analysis showed that glycosylated hemoglobin level was significantly negatively with full, verbal and operation intelligence quotients in diabetic children (r=-5.64, -7.29, -3.00 respectively; P<0.05).
Conclusions:
Type 1 diabetes may affect adversely children's verbal intelligence quotient, resulting in a decreased full intelligence quotient. Glycosylated hemoglobin may be an independent risk factor for cognitive function in diabetic children.
