Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s waste-clearing systems. The discovery may explain how circulation changes contribute to Alzheimer’s and other neurodegenerative diseases.
