Neurocognitive Changes in Sickle Cell Disease: A Comprehensive Review

Area of Science:

• Neurology
• Hematology
• Cognitive Science

Background:

• Sickle cell disease (SCD) is a hemoglobinopathy with diverse acute and chronic complications.
• Neurological issues like stroke, silent infarction, headache, and neurocognitive impairment are prevalent in SCD.
• Anemia in SCD can lead to cerebral hypoxia, exacerbating cognitive deficits.

Purpose of the Study:

• To review the neurocognitive aspects of sickle cell disease.
• To explore the impact of SCD on cognitive functions such as memory, learning, executive functions, and attention.
• To discuss the association between neurocognitive impairments and functional outcomes in SCD patients.

Main Methods:

• Review of literature focusing on neurocognitive deficits in SCD.
• Analysis of findings from various neuroimaging techniques.
• Examination of psychological testing batteries and neuromarkers.
• Evaluation of interventions for managing cognitive deficiencies in SCD.

Main Results:

• SCD is linked to widespread neurocognitive impairments affecting multiple cognitive domains.
• Neuroimaging studies reveal structural and functional brain changes in SCD patients.
• Cognitive deficits in SCD correlate with poorer functional outcomes and quality of life.

Conclusions:

• Neurocognitive impairment is a critical complication of sickle cell disease.
• Comprehensive assessment and management strategies are essential for addressing cognitive deficits in SCD.
• Further research is needed to develop targeted interventions for SCD-related cognitive dysfunction.
