Researchers at USC's Keck School of Medicine have identified new cerebrovascular indicators that may signal Alzheimer's disease risk by examining blood flow and oxygen delivery in the brain. Utilizing noninvasive techniques like transcranial Doppler ultrasound and near-infrared spectroscopy, the study connects these indicators with established imaging markers of Alzheimer’s, suggesting that regulating blood and oxygen supply is vital in understanding cognitive health. The findings indicate that patients with greater vascular stability align with lower amyloid and larger hippocampal volumes, potentially aiding early detection of Alzheimer's progression.
