Up to 50 Years Before Diagnosis

1 Sleep Disorder May Be a Sign of Impending Dementia

Rapid Eye Movement (REM) sleep behavior disorder, in which people act out their dreams with violent movements, may be an indicator of dementia and Parkinson’s disease, finds research published in the journal Neurology®. Mayo Clinic records identified patients with REM sleep behavior disorder before they developed dementia or Parkinson’s and found that the time between the two incidents could be as long as 50 years. "More research is needed on this possible link so that scientists may be able to develop therapies that would slow down or stop the progression of these disorders years before the symptoms of Parkinson's disease or dementia appear," said study author Dr. Bradley F. Boeve. It’s not known how many people who have REM disorder may later develop neurologic diseases.

2 Calcium Supplements Increase Heart Attack Risk

A study published online in the British Medical Journal has found that calcium supplements are associated with an increased risk of heart attack and cardiovascular events in healthy older women. An international team of researchers analyzed the results of 11 randomized controlled trials of calcium supplements involving 12,000 patients. They found that calcium supplements were associated with about a 30 percent increased risk of heart attack, and smaller increases in the risk of stroke and mortality. Previous studies have found no increased cardiovascular risk with increased dietary calcium intake, such as drinking milk, suggesting the risks are restricted to supplements. The authors suggest a reassessment in the role of calcium supplements in osteoporosis management.

3 White Button Mushrooms Keep Immune System Healthy

In the United States, white button mushrooms represent 90 percent of the total mushrooms consumed. Researchers have found that the commonly enjoyed vegetable plays an important role in keeping the immune system healthy. An Agricultural Research Service (ARS) funded study, conducted at the USDA Human Nutrition Research Center on Aging at Tufts University, found that white button mushrooms promote immune function by increasing production of antiviral and other proteins that are released by cells while seeking to protect and repair tissue. Nutrients within the mushrooms enhance the maturity of dendritic cells from bone marrow which make T-cells. T-cells are white blood cells which recognize and deactivate antigens or invading microbes.
