It turns out “do what makes your heart happy” is not just a self-help cliché. Scientists recently identified another reason to take good care of one’s heart: a link between vascular health and Alzheimer’s Disease. A plasma component named Factor XII, usually involved in blood clotting and inflammation, may play a part in Alzheimer’s Disease for some patients. Reducing Factor XII in mice with AD showed less brain inflammation and better memory function than untreated AD mice. It is still unclear how changes in one’s blood might catalyze the disease, but the discovery corroborates previous findings that people with compromised vascular systems are at increased risk for AD.
