Tech Explorist covered a study by Daniel Nation that explores the relationship between cerebrovascular reactivity (CVR) in the medial temporal lobe and memory function in older adults, particularly those with and without mild cognitive impairment (MCI). “We’re studying the ability of these very small vessels to respond to stimuli and to dilate, and they’re showing dysfunction in people who have memory problems. … It could implicate blood vessel dysfunction in a very early stage of memory loss. It happened whether or not people had Alzheimer ‘s-related brain changes. They still had this blood vessel problem if they had memory issues.”
