Summary

Story summary

Researchers from the University of Southern California (USC) developed a noninvasive imaging method to measure pulsations of tiny brain blood vessels.
The method combines vascular space occupancy and arterial spin labeling MRI to reveal age- and risk-related changes.
The study found that older adults with high blood pressure have significantly stronger pulsations in deep white matter.
Deep white matter is linked to cognitive decline and Alzheimer's disease.
