Many people with dementia have poor blood flow to the brain. This happens when a protein called Piezo1 gets stuck "on," acting like a broken switch. Scientists at the University of Vermont found that a fat called PIP2 is the missing "off switch" needed to fix it. By adding PIP2 back, they were able to reset the protein and restore healthy blood flow. This discovery is a huge win because it could lead to new treatments that stop dementia early, helping millions of people stay mentally sharp as they age.
