In 2019, researchers discovered meaningful insights into the causes, risk factors and treatment of Alzheimer’s disease and other dementias. Here are five of their important discoveries:
1. Lifestyle may play a major role in reducing risk. We’re told that eating a healthy diet and exercising are good for overall health, but did you know that these habits may also reduce one’s risk for cognitive decline and dementia? Research reported at this year’s Alzheimer’s Association International Conference suggested that making multiple healthy lifestyle choices — including eating a low-fat, high vegetable diet, not smoking, getting regular exercise and engaging in cognitive stimulation — may decrease dementia risk and may even offset increased risk caused by genes or exposure to air pollution. This year, researchers also learned that intensive high blood pressure treatment can significantly reduce the occurrence of mild cognitive impairment, which often leads to dementia.
2. A blood test is on the horizon. Researchers are working at full speed to develop a simple blood test that can detect signs of Alzheimer’s early and accurately. Blood tests are cheaper, easier to administer, less invasive and more accessible than many advanced technologies currently available for Alzheimer’s research and diagnosis. Once these tests become available in doctors’ offices, they may also play a role in early detection of dementia, giving individuals and families more time to plan for the future and get needed care and support services, and potentially increase their chances of participating in clinical trials.
