Groundbreaking Study by University of Utah Reveals Key Connection Between Blood Pressure and Brain Health

In six giant freezers at the University of Utah, nearly 40,000 blood samples are waiting. These samples come from a major study on high blood pressure, known as the SPRINT trial. Inside them, scientists hope to find clues about brain health, including conditions like Alzheimer’s disease.

Thanks to a new grant of $21.6 million from the National Institutes of Health, researchers are ready to dig deep into these samples. They want to explore how high blood pressure might relate to Alzheimer’s and other dementias, which are among the leading causes of disability for older adults.

High blood pressure is a big player in dementia risk. Alzheimer’s, the most common type, is linked to protein buildups in the brain. However, high blood pressure may also cause issues with blood vessels that affect cognitive function. While we know it’s harmful, the exact connections and how managing blood pressure could help are still unclear.

This study aims to analyze blood molecules that might indicate the presence of Alzheimer’s or other cognitive declines. Adam Bress, a professor at the University of Utah, leads the research. He wants to answer several critical questions:

• How does aggressive blood pressure treatment impact brain health?
• Do these treatments affect Alzheimer’s-related brain changes?
• How does existing Alzheimer’s pathology influence blood pressure management?

An exciting part of this study is the use of a new blood biomarker. This biomarker can identify early Alzheimer’s changes almost as effectively as traditional methods like brain scans. By comparing these biomarkers with detailed health information, researchers hope to see how blood pressure treatments can vary based on individual factors like genetics and health history.

Rachel Hess, a leader in research at the University, emphasizes the value of having such a comprehensive biobank. This resource allows them to look back at samples that could be years old and apply new findings related to blood pressure control and aging.

The ultimate goal? To help doctors make better decisions based on patient-specific data. A more personalized approach could lead to more effective treatments, especially for those at higher risk for dementia.

Experts in the field like Jeremy Pruzin, a neurologist, highlight the study’s potential impact. Understanding how blood pressure affects dementia risk can lead to better treatment strategies. Likewise, Jasmeer Chhatwal from Harvard Medical School believes this research could transform how we diagnose and treat cognitive impairments.

Angela Fagerlin from the University of Utah adds that using blood biomarkers with clinical data will illuminate the links between hypertension and brain health. She believes the outcomes of this study could vastly improve the quality of life for many older adults.

Overall, the combination of advanced research and extensive data from the SPRINT trial positions this study to make significant strides in understanding brain health and managing hypertension.
