Is this trial a fit for you?

Likely a good fit

Ideal candidates are children and adolescents aged 6-18 years diagnosed with sickle cell disease of any genotype.

Probably not a fit

Patients with prior abnormal brain MRIs unrelated to sickle cell disease or those unable to provide informed consent may not benefit from this study.

What this trial studies

This study evaluates the changes in brain structure and neurocognitive development in children and adolescents aged 6-18 years with sickle cell disease (SCD) over a four-year period. It aims to understand the relationship between brain structure, biomarkers, and cognitive functioning by comparing SCD patients with a healthy cohort. Participants will undergo MR scans, blood work, neurological examinations, and neuropsychological assessments to gather comprehensive data on brain health and cognitive abilities. The study seeks to identify the timing and nature of brain tissue damage in relation to other organ systems affected by SCD.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cognitive impairments in children with sickle cell disease.

How similar studies have gone: While studies on sickle cell disease exist, this longitudinal approach focusing on brain development is relatively novel and untested.
