The South Bronx has been identified to undergo from poor air high quality and well being inequality for many years, however now that scourge might be linked to a different public well being downside: Alzheimer’s illness. In response to knowledge from the Coalition of New York State Alzheimer’s Affiliation Chapters, greater than 426,500 New Yorkers aged 65 and older have the situation. New York is second among the many 5 states with the best projected prevalence of Alzheimer’s, at 12.7% — and at 16.6%, Bronx county has the best prevalence within the state.
These statistics tackle new that means with the findings of a research launched in November 2024 by the Dementia Threat Discount Challenge displaying that three of 12 threat elements that will affect dementia threat are smoking, air air pollution, and diabetes. The Bronx has the second-highest proportion of grownup people who smoke at 11.7%, barely behind Staten Island at 12%.
Analysis signifies that air high quality within the South Bronx is poor due to factories, business, and hundreds of vans shifting by means of the neighborhood emitting nitrogen oxide. The Dementia Threat Discount Challenge discovered that extended publicity to air air pollution considerably raises dementia threat.

“Research have proven that tremendous particulate matter — a part of air air pollution — can penetrate the physique and attain the mind,” mentioned Dr. Chris Vercammen. “Whereas the exact relationship between air air pollution and dementia remains to be being studied, researchers have discovered that this particulate matter can result in power irritation all through the physique, together with throughout the mind itself.”
Vercammen defined that this irritation might be damaging to mind cells and will contribute to cognitive decline. As well as, sure chemical air pollution can have poisonous results on each the physique and mind cells, doubtlessly resulting in cognitive impairment.
Prevalence of diabetes amongst New York Metropolis residents additionally makes the outcomes of this research vital, with roughly 16% of Bronx residents being identified with the ailment, the best fee by county within the state. Elevated fasting plasma glucose (FPG) ranges, a marker of diabetes, are linked to an elevated threat of dementia, with an roughly 25% enhance in threat even at prediabetes ranges and a 50% enhance in threat on the threshold for diabetes analysis.
“Individuals with diabetes have constantly elevated blood sugar over time, which may injury your blood vessels, result in power irritation, and contribute to atherosclerosis, all of which may have a unfavourable affect in your mind,” mentioned Dr. Raj Dasgupta. He added that insulin resistance, usually linked to an elevated FPG, can even intervene with how mind cells talk and filter dangerous proteins. All of this will increase the chance of neurodegeneration, making circumstances like Alzheimer’s extra seemingly. As blood glucose ranges enhance additional, dementia threat continues to rise.
Rising diabetes fee mixed with extended publicity to air air pollution make it simple to grasp why Alzheimer’s illness is a rising downside in New York Metropolis.
“By understanding and influencing dementia threat elements, we will disrupt dementia,” mentioned Sarah Lock, AARP senior vice chairman for coverage and govt director of the International Council on Mind Well being (GCBH). “We will use this data to advertise more healthy brains and empower folks to decrease their very own dangers, doubtlessly delaying dementia onset and fostering wholesome getting older. This analysis goals to provide older People extra high quality time with family members. Via this first-of-its type analysis endeavor, AARP hopes to glean and share data on the connection between potential dangers and dementia and the way can we will scale back these dangers for older People.”
This research has even better implications for Black and Brown New York Metropolis residents. Within the Bronx, the place air pollution is the best, the racial make-up is 56.6% Hispanic and 28.2% Black. Coupled with statistics displaying that 14.5% of New Yorkers identified with diabetes are Black,and 11.7% are Hispanic, the chance of Black and Brown New Yorkers is clearly better. As well as, Black People with Alzheimer’s usually tend to be identified later.
With rising analysis, it turns into extra apparent that analysis and remedy of Alzheimer’s and dementia in New York Metropolis is a well being fairness situation. “If these are points that disproportionately have an effect on communities of shade, and these points are tied to elevated threat of dementia, then you may put that collectively and say communities of shade are extra impacted as a result of the underlying elements of how and the place folks stay expose us to greater ranges of threat,” mentioned Doris Phildor, MPH, well being system director of the Alzheimer’s Affiliation, NY.
