Neurocognitive sequelae of sickle cell disease: current issues and future directions

Area of Science:

• Genetics and Hematology
• Pediatric Neurology

Background:

• Sickle cell disease (Hgb SS) is an inherited blood disorder common in individuals of African American and Mediterranean descent.
• Cerebral vascular accident (stroke) is a significant complication of sickle cell disease in children, impacting physical and neurocognitive functions.
• Emerging evidence indicates neurological deficits in children with sickle cell disease, even without overt stroke symptoms, detectable via MRI and neurological exams.

Purpose of the Study:

• To review and delineate current research areas concerning risk factors for cerebral vascular accident (CVA), silent infarcts, and neurocognitive deficits in children with sickle cell disease (Hgb SS).

Main Methods:

• Literature review of recent studies on neurological complications in pediatric sickle cell disease.
• Analysis of findings from magnetic resonance imaging (MRI) and neurological examinations.
• Exploration of identified risk factors for CVA and silent infarcts.

Main Results:

• Children with sickle cell disease (Hgb SS) may exhibit neurological deficits not clinically apparent.
• Subtle neurological impairments can be detected through advanced imaging and detailed examinations.
• Research is actively identifying specific risk factors contributing to stroke and silent infarcts in this population.

Conclusions:

• Further research is crucial for understanding and addressing the neurological impact of sickle cell disease (Hgb SS) in children.
• Continued investigation into risk factors and early detection methods is needed for effective intervention.
• The field is advancing in identifying and characterizing neurological deficits in pediatric sickle cell disease.
