How sickle cell trait affects brain health and cognitive function in older adults

Interaction of sickle cell trait with human apolipoprotein E ε4: Impact on brain structure, brain lipidomics, neuroinflammation and cognitive deficit

NIH-funded research University of Cincinnati · NIH-10993275

This study is looking at how having sickle cell trait might affect brain health, especially in older African Americans, by exploring its connection with a gene linked to Alzheimer's disease, and it involves brain scans and memory tests to better understand these effects.

What this research studies

This research investigates the relationship between sickle cell trait and brain health, particularly focusing on how it interacts with a specific gene variant (apolipoprotein E ε4) that is linked to Alzheimer's disease and related dementias. The study aims to understand how these factors influence brain structure, lipid composition, neuroinflammation, and cognitive deficits in older adults, especially within the African American population. By analyzing brain imaging and lipid profiles, the research seeks to uncover potential biological mechanisms that contribute to cognitive decline. Participants may undergo assessments that include brain scans and cognitive tests to gather data on these interactions.

Who could benefit from this research

Good fit: Ideal candidates for this research are older adults aged 65 and above, particularly those of African ancestry who carry the sickle cell trait.

Not a fit: Patients who do not have sickle cell trait or are under the age of 65 may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and targeted interventions for cognitive decline in older adults with sickle cell trait.

How similar studies have performed: While the interaction of sickle cell trait and cognitive decline is a relatively novel area of investigation, previous studies have shown that genetic factors can significantly influence dementia risk, suggesting potential for impactful findings.
