Brain health warning sign could be hiding in plain sight, say researchers (Fox News)

Fox News covered a study led by Professor Daniel Nation showing that rapid beat-to-beat fluctuations in blood pressure may signal early brain health problems—even when overall readings look normal. “Even when blood pressure is well-controlled with medication, the rapid fluctuation in blood pressure from heartbeat to heartbeat is associated with worse memory and signs of brain shrinkage and brain cell injury,” he said.
