Cognitive Functions and Psychological Problems in Children with Sickle Cell Anemia

Area of Science:

• Pediatric Hematology
• Neuropsychology
• Child Psychology

Background:

• Sickle cell anemia (SCA) is a genetic blood disorder with known systemic effects.
• Cognitive and psychological impacts in pediatric SCA are increasingly recognized.
• Comprehensive assessment is needed to understand the full spectrum of SCA's effects on children.

Purpose of the Study:

• To investigate cognitive function deficits in children diagnosed with sickle cell anemia.
• To identify the prevalence and nature of psychological problems in pediatric SCA.
• To compare cognitive and psychological profiles of children with SCA against a healthy control group.

Main Methods:

• Utilized the Malins Intelligence Scale for Indian children to assess IQ.
• Employed the modified PGI memory scale for memory function evaluation.
• Administered the Childhood Psychopathology Measurement Schedule for psychological assessment.
• Compared SCA children with age, sex, and community-matched controls.

Main Results:

• Children with SCA showed significantly lower verbal, performance, and full-scale IQ scores (77, 81, 78) compared to controls (92, 95, 93).
• Higher incidence of borderline intellectual functioning (70%) and mild mental retardation (16%) observed in the SCA group.
• Impaired attention, concentration, and working memory were noted in children with SCA.
• Children with SCA presented with a greater number of behavioral problems than controls.

Conclusions:

• Cognitive functions are demonstrably impaired in children with sickle cell anemia.
• Children with SCA are more prone to psychological and behavioral issues.
• Integrating early identification and remediation services for intellectual and psychological problems into SCA healthcare is recommended.
