Novel markers of brain blood flow and oxygenation may offer early clues to Alzheimer’s risk

NGP Student Amaryllis A. Tsiknia led new research that suggests vascular health of the brain may play an important role early in the disease process and could help identify individuals at risk before significant symptoms appear.

Amyloid PET imaging was used in the study to measure plaque buildup in the brain, a hallmark of Alzheimer’s disease. Warmer colors indicate higher amyloid levels. Participants with healthier patterns of brain blood flow and oxygen regulation had lower amyloid burden, reinforcing the idea that vascular function may be linked to Alzheimer’s-related changes.
