Self-help enthusiasts had it partially right

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.

4. The trouble with statins

One of the most widely prescribed types of drugs on earth may be a Catch-22. Statins, a group of drugs used to lower cholesterol, are now shown to decrease the benefits of exercise (like um, improving cardiovascular health).  Not only that, but they may make getting off the couch and to the gym harder than it already is. Insult to injury, anyone? Researchers at the University of Illinois found that while cholesterol levels improved in statin-injected mice, these mice exhibited more muscle weakness, more pain, and diminished exercise levels compared to the control group. And while the control group showed improved muscle fitness post-exercise, the statin mice showed little to none. One step forward and how many steps back? Until we figure it out, here’s a Harvard Health Publications strategy for lowering cholesterol with foods.
