What the research found
ScienceDaily, on 28 October 2026, reported a University of Virginia paper by Souza, Abbott, and colleagues in Circulation Research (2026; 138(4), DOI 10.1161/CIRCRESAHA.125.326792), with NIH support HL148004. The paper title is Control of Blood Pressure Variability Across Behavioral States by Brainstem Adrenergic Neurons. Loss of a few hundred of these nerve cells produced unstable blood pressure while the average pressure stayed normal. The same cells have been found damaged or missing in multiple system atrophy. The release used here does not state the species or a human sample size. This does not describe a remedy for blood pressure. Not medical advice.
