Animal study presents best evidence to date that Parkinson’s begins in the gut

“An important and rigorous new animal study led by scientists at Johns Hopkins University has demonstrated how the misfolded proteins thought to cause Parkinson’s disease may originate in the gut, and travel up to the brain via the vagus nerve. This research builds on a compelling body of evidence pointing to a gut-brain connection in the disease and hints at possible new treatment pathways.” learn more

Study links nutrients in blood to better brain function

The interesting thing to me here is the methodology. They used nutrient biomarkers in blood instead of surveys to understand diet, and fMRI scans rather cognitive tests to understand brain activity. “A new [University of Illinois] study links higher levels of several key nutrients in the blood with more efficient brain connectivity and performance on cognitive tests in older adults.” | learn more
