Dementia rate declines but aging America may halt the trend

"R$3 ecent studies suggest that the age-specific risk of dementia may have actually declined in some high-income countries over the past 25 years, perhaps owing to increasing levels of education and better control of key cardiovascular risk factors, such as hypertension, diabetes, and hypercholesterolemia", the authors of the new study wrote.
The number of people in the USA with Alzheimer's disease and other geriatric cognitive syndromes declined significantly between 2000 and 2012, according to a nationally representative longitudinal study.
While Dr Langa and colleagues noted that their study provides further support to the theory of "cognitive reserve" - the theory that early-life and lifelong education, as well as cognitive stimulation, may give individuals the ability to better tolerate or compensate for cognitive abnormalities - they also noted that the associations between education, brain biology, and cognitive function are complex, and that there may be other explanations. Researchers found that the people in the study who had more years of education had a lower risk of dementia. Dr. Kenneth Langa, a professor of medicine at the University of MI and the lead author of the study, says that researchers don't know why education should be a protector against dementia, but they have some theories.
NEW YORK (AP) - President-elect Donald Trump is planning to meet on Monday with Oklahoma Gov. Mary Fallin and.
In a hopeful sign for the health of the nation's brains, the percentage of American seniors with dementia is dropping, a new study finds.
BEDMINSTER, N.J. (AP) - Vice President-elect Mike Pence says Mitt Romney is "under active considerationR". It means, he said, that "roughly a million and a half people aged 65 and older who do not have dementia now would have had it if the rate in 2000 had been in place".
More than 5 million Americans have Alzheimer's disease. This number represents an increase from 2000, in which roughly 12.5 percent of the USA population was 65 or older, and is in line with the trend that predicts a rise to 21.7 percent by 2040.
The falling rates of dementia suggest there are modifiable factors, such as education and cardiovascular health, that reduce your chances of developing Alzheimer's. People with more education tend to earn more money and have better access to health care.
Dementia impairs patients' memory and cognitive skills.
For those who do develop dementia, Langa notes, the challenge for America going forward will be to address the need for long-term care at home and in institutions, in the face of smaller families with fewer members to act as caregivers. John Haaga, director of the National Institute on Aging's behavior and social research division, said dementia rates would have to decline much more sharply than they have to counteract that trend.
Dementia rates have dropped since 2000, a new study reveals. Continued monitoring of trends in dementia incidence and prevalence will be important for better gauging the full future societal impact of dementia as the number of older adults increases in the decades ahead. They're less likely to smoke, more likely to exercise and less likely to be overweight.
"Although the putatively protective role of education against dementia risk is presently well accepted, several aspects of this phenomenon continue to generate controversy".
"We think that two factors were likely important in this trend toward better brain health in the United States", Langa said. "These differences in education and wealth may actually be creating disparities in brain health and, by extension, the likelihood of being able to work and be independent in our older years". But a journal editorial says more research is needed to determine whether excess pounds in older age somehow protect the brain.
