Running on Empty: Blood Flow, Brain Energy, and Dementia
Join Professor Catherine Hall at the University of Sussex as she journeys through your brain’s 400 miles of blood vessels and explains how they keep your brain healthy and what happens to our brains when blood vessels go wrong.
“Thinking really is hungry work, and not feeding our brains enough might start them on the path to dementia. I want to understand how so we can stop that from happening.”
Catherine’s research studies how the brain’s blood vessels work, what happens to brain cells when they don’t get enough blood, and why some parts of the brain go wrong more quickly when that happens. She is a Professor of Neurovascular Science in the School of Psychology and Sussex Neuroscience, at the University of Sussex and a Professorial Research Fellow at University College London in the British Heart Foundation and UK Dementia Research Institute’s Centre for Vascular Dementia Research.
