The Nutrients You Need to Fight Off Alzheimer's

Salmon is a great source of vitamin D and omega-3 fatty acids , two nutrients that may help fight off Alzheimer's disease. Alzheimer's disease is one of the most trying illnesses that affects seniors, burdening families and the U.S. healthcare system. According to the Alzheimer's Association, one in eight older Americans has the disease, which is the sixth-leading cause of death in the country. As of yet, there is no cure. However grim these statistics are, an influx of funding through the National Alzheimer's Project Act has allowed scientists to make great strides in the fight against the condition.

Several recent studies offer some tangible - and edible - advice that may help senior care providers or those offering Alzheimer's care to better support an older adult who has this disease. Vitamin D, omega-3 fatty acids, green tea and red wine extracts have all been found to play a role in the treatment of Alzheimer's. 

Vitamin D
The "sunshine vitamin" that can be found in foods like salmon, sardines, milk and eggs was proven to assist the immune system in the process of clearing the brain of amyloid-beta plaques, a hallmark of Alzheimer's disease. In a study published in the Journal of Alzheimer's Disease, researchers discovered vitamin D3 regulates key genes and signaling networks that boost the immune system's ability to clear these harmful plaques from the brain. 

Omega-3 fatty acids
The same study showed that omega-3 fatty acid DHA can also help clear these plaques because of the way it reduces inflammation and promotes the absorption of amyloid-beta plaques, instead of allowing them to build up. Omega-3 fatty acids can be found in flaxseeds, walnuts, salmon, scallops, shrimp and tofu, according to U.S. News and World Report.

Green tea
Green tea has long been lauded for its antioxidant properties, and now a study from the University of Leeds suggests it could disrupt a critical step in the development of Alzheimer's disease. The study, published in the Journal of Biological Chemistry, determined that purified green tea extracts were effective in interrupting the process by which harmful amyloid plaques can build up and latch onto brain cells, causing the cognitive symptoms of the disease. 

Red wine
Purified resveratrol extracts from red wine had the same effect as the green tea extracts, the study found. Researchers are now exploring whether these extracts could be used in drugs to target Alzheimer's disease. Until then, a cup of green tea or a glass of red wine might offer good sources of these powerful antioxidants.

New Study Refutes Link Between Memory Loss, Statins

New Study Disclaims Link Between Memory Loss, Statins A new paper published in the Annals of Internal Medicine may disprove previous claims about the connection between statins and cognitive function. According to Forbes, the Food and Drug Administration issued a warning in 2012 that linked statins to memory loss and confusion - an assertion that remained unchallenged until the release of new studies conducted by scientists at the University of Pennsylvania and Stanford University. Analysis of random, controlled trials as well as cross-sectional studies resulted in no conclusive ties between cognitive disorders and statin use, the researchers reported, although they indicated in their conclusion that further research could provide greater insight.

Correlation Identified Between Dementia And Heart Disease In Older Women

Correlation Believed Between Dementia And Heart Disease In Older Women New studies reveal that women over the age of 65 may be at a higher risk of developing dementia if they previously experienced heart issues. According to Reuters, research indicated that residents of senior living who have previously had a heart attack face the highest chances of memory loss, although heart failure and arrhythmia were not definitively linked to cognitive decline.

Stress Tied to Increased Alzheimer's Risk

Stress Might Be Tied To Increased Alzheimer's Risk Stress can have an impact on health in a wide variety of ways. For instance, those who experience high levels of stress often face a greater risk of cardiovascular disease, according to the World Heart Foundation. A new study from Gothenburg University in Sweden found that people who deal with a high level of stressors on a day-to-day level may also have a greater risk of developing Alzheimer's disease later in life, according to results published in BMJ Open.

Recognizing Memory Loss Issues Could be Indicator of Cognitive Decline

If you are concerned about issues with memory loss, discuss the problem with your doctor. Mild memory loss is a natural part of senior living. Older adults will sometimes have trouble remembering names or appointments, but will be able to remember them soon after, according to the Alzheimer's Association. Seniors might have a hard time coming up with certain words on the spot, but it shouldn't take them too long to recall it in most cases.These issues differ from dementia-related memory loss, and it's important for older adults and their caregivers to be able to recognize the difference.
