The specific protein, known as p-tau217, forms "tangles" in the brain that disrupt communication between nerve cells. In a healthy brain, tau helps to stabilize the structure of nerve cells.
In some cases, brain scans can be used to detect these tangles when diagnosing Alzheimer’s. Preliminary studies have suggested that the same method could be used to determine a progression timeline.
