1 Eating Fish May Reduce Alzheimer’s Risk

Eating baked or broiled fish may reduce the risk of developing mild cognitive impairment and Alzheimer’s disease, finds a study from the U of Pittsburgh Med Ctr and the U of Pittsburgh Schl of Medicine. The study is the first to establish a direct relationship between fish consumption and brain health. The study found, through 3-D volumetric MRIs of the brain, that weekly consumption of fish positively impacted the volume of gray matter, a crucial component of brain health. Decreases in the brain’s gray matter indicate that brain cells are shrinking. “We found higher levels of working memory in people who ate baked or broiled fish on a weekly basis, even when accounting for other factors, such as education, age, gender and physical activity," says researcher Dr. Cyrus Raji.

Detroit Tops List of Eight

2 Magazine Names Worst Cities for Heart Disease

Prevention magazine placed Detroit, Michigan on top of their list of the cities with the highest rates of obesity and heart disease in the U.S. The magazine came up with the list after analyzing the most recent obesity and heart disease information from the CDC. The list is made up of the most at-risk metropolitan cities with populations of more than 200,000 residents. Other cities named for their ability to clog your arteries include Fort Wayne, Indiana; Lubbock, Texas; New Orleans, Louisiana; Dallas, Texas; Baton Rouge, Louisiana; Tulsa, Oklahoma; and Louisville, Kentucky. Prevention cautions that unhealthy habits are contagious. That means anyone moving to or spending time in any of the eight named cities should pay extra attention to their hearts!

Mice Can Smell Again

3 Researchers Reverse Earliest Sign of AD

New research in mice shows that the loss of smell which can be an early sign of Alzheimer’s Disease (AD), can be reversed by reducing the beta amyloid that accumulates in patients’ brains. Mice that were treated with a synthetic liver x-receptor agonist that cleared amyloid beta from the brain allowed them to smell normally within two weeks. Only a very small amount of amyloid beta is required to cause smell loss and it accumulates in that part of the brain long before it does in areas that affect coordination and cognition. Researchers were able to see the activity level in the olfactory bulb decrease as levels of the protein increased. Screening people by testing their sense of smell is likely a valid way to assess their AD risk and can allow treatment to begin early.
