Those familiar with Human Biodiversity (HBD) are aware of the ubiquitous hierarchy of races Asian-white-Hispanic/Mideastern-black. Average IQ, propensity for violence, time-orientation, muscle-mass, bone-density, and several other traits follow this pattern.
So it shouldn’t be surprising that a study of dementia fell in line with this pattern. A Medicalexpress.com article reports:
This is the first study to look at dementia risk in a large population representing the diversity of the United States. Researchers found dementia incidence to be highest in blacks and American Indian/Alaska Natives, lowest among Asian Americans, and intermediate among Latinos, Pacific Islanders and whites.
While the article doesn’t actually assume that these disparities are the result of environmental factors, it does conclude:
The researchers emphasize that while this study documents racial and ethnic disparities in dementia, the next step is to understand the mechanisms driving these inequalities.
“Based on the present study, we cannot determine the extent to which genetic or social and behavioral factors contribute to the observed patterns,” said Whitmer. “But if social and behavioral factors are the primary pathways, these findings suggest substantial reductions in dementia incidence are possible.”
That’s a big “IF.” And it’s an “if” that comes with its own assumption: That different behaviors are not linked to different DNA. Even if it can be shown that these disparities are the direct result of different habits, it must still be shown that these habits are divorced from each race’s genetics. In today’s political climate, such questions are not likely to even be asked, let alone researched.
We’re told that…
“This study has major public health implications. If all individuals aged 65 or older had the same rate of dementia as Asian Americans, 190,000 cases of dementia would be prevented annually,” Whitmer added. “These findings underscore the need to better understand risk factors for dementia throughout life to identify strategies to eliminate these inequalities.”
A true scientist would explore all possibilities, not just the politically correct ones. Whether the main risk factors are environmental or genetic, this is yet another argument to carefully select who immigrates to the United States. It would be interesting to see what the dementia rates are for countries in Africa or Brazil. With current trends, our future could be one where those who make it to old age will have nobody to care for them, and where dementia patients will be on their own.
