October Research Round-Up: Findings for Vibrant Aging


From an “engineered” blue zone, to the benefits of the flu shot in preventing Alzheimer’s, to the evils of sitting even if you exercise.  These articles and research can help us keep our minds vibrant as we age!

Singapore is the newest blue zone. It’s being called an engineered blue zone because innovative policy initiatives like restaurant discounts when you’ve logged 10,000 steps, tax breaks for living close to older relatives, and subsidized healthy food have all served to boost life expectancy there by 20 years since 1960.

Prior investigations have demonstrated that individuals who had received at least one flu shot had a 40% reduced risk of developing Alzheimer’s in comparison to those who hadn’t undergone any vaccination. Fresh research findings suggest that other routine adult vaccines present a viable and easily accessible approach to Alzheimer’s prevention. To illustrate, when researchers examined various individuals, they observed that those who had received the Tdap/Td vaccine (for whooping cough) were 30% less likely to develop Alzheimer’s than those who hadn’t been vaccinated. It is plausible that vaccines alter the behavior of the immune system as it encounters the accumulation of harmful proteins in the brain, a process associated with the onset of Alzheimer’s disease. They may enhance the efficacy of immune cells in clearing these detrimental proteins or potentially bolster the immune response, thus safeguarding neighboring healthy brain cells.

People who sit 10 or more hours a day have an 8% greater risk of developing dementia within seven years. And, if you think you can exercise to make up for all the sitting time, think again!
