New Research Links Body Movement to Brain Health, Offering Potential Alzheimer’s Defense
Scientists at Penn State University have made a groundbreaking discovery that links simple body movement to brain health. This could revolutionize our understanding of Alzheimer’s prevention and cognitive wellness.
The research, published in Nature Neuroscience on May 1, 2026, reveals that each time you engage your abdominal muscles, even slightly, your brain experiences a gentle sway within your skull. This subtle motion, triggered by pressure changes in connected blood vessels, may aid in circulating cerebrospinal fluid around the brain. This process potentially flushes out harmful waste that can disrupt normal brain function.
Employing microCT scanning and advanced imaging techniques, the researchers discovered a network of veins that form a mechanical link between the abdominal cavity and the brain. When the abdominal muscles contract, they exert pressure on blood vessels connected to the spinal cord and brain, causing the brain to shift slightly within the skull.
“Our research explains how just moving around might serve as an important physiological mechanism promoting brain health,” said Patrick Drew, professor of engineering science and mechanics at Penn State and corresponding author on the paper. “In this study, we found that when the abdominal muscles contract, they push blood from the abdomen into the spinal cord, just like in a hydraulic system.”
This discovery builds on earlier research into the brain’s natural cleaning system. It could have significant implications for preventing neurodegenerative diseases like Alzheimer’s through simple physical activity.
