New research appears to highlight another tragic aftereffect of the 9/11 terror attack . Scientists have found evidence that responders expose to dust and debris from the collapse of the World Trade Center are more likely to acquire former onset dementia . The findings also advise that protective personal equipment can aid mitigate this risk should a similar disaster ever happen again .
The inquiry was top by scientists from Stony Brook University . Stony Brook has maintained along - track programtreating and track the wellness of 9/11 responders . As part of this curriculum , epidemiologist Sean Clouston and his colleagues have specifically focused on the long - terminus genial and cognitive outcome of these survivors .
The team haspreviously studiedhow the chronic PTSD suffered by some respondent may have conduce to other linger health issues . But while theydid finda connection between PTSD and modest cognitive handicap in this mathematical group , they also find that many survivors without PTSD were experience these problems as well , which led them to grind deeper . Knowing that some study have begun to regain a connection betweenair defilement and dementia , they theorize that dust and rubble exposure among these responders could be a cardinal element .

In this newfangled survey , the researchers canvas the cognitive health of center - aged respondent between 2014 to 2022 , specifically look for diagnosed cases of other - oncoming dementedness — an particularly rarified condition before the eld of 65 . Based on self - reported accounts of their experience in the aftermath of the 9/11 attack , the team grouped responders by the stratum of exposure they likely experience as well as whether they were wear down mask or other protective equipment during their travail .
While the team did hope to spot evidence for their hypothesis , even they were surprised by how promptly apparent this connection was in their sample . Of the 5,010 volunteer under eld 60 examined , 228 had been diagnosed with early dementedness . The more rubble that people were divulge to , the neat their betting odds of having dementedness , even after adjusting for other potential factors , such as high blood pressure or a history of head teacher injuries . Those in the most austere exposure chemical group were over nine times more probable to develop dementia compare to the lowest picture group after adjusting for these factors , and substantially more potential than the universal public .
“ We did see very quickly that the people who did n’t account any dust exposures , the people who always wear masquerade party , seemed to be at a very blue endangerment , and then for the sleep , the risk of make grow dementia increase incrementally by the more picture that the great unwashed report , ” Clouston tell Gizmodo . The squad ’s resolution werepublishedWednesday in the daybook JAMA web Open .
These sorts of studies can only prove a correlativity between two things , not a direct cause - and - gist relationship . But the authors have pile up other suffer data , such as previousresearchshowing a tie-in between exposure to 9/11 junk and mensurable marker in the Einstein consociate with dementia , such as neuroinflammation . Other research hasfoundthat exposure to this dust can worsen cognitive wellness in mice .
The report does bestow more weight to the general idea that air pollution can be severe to our brains , though Clouston notes that 9/11 survivor were exposed to a full range of pollutants , some of which would rarely be encountered anywhere else . At the same time , comparatively common disasters , such as wildfires that reach buildings and homes , could conceivably divulge the great unwashed to similar kinds of pollution , so the implications of this inquiry could be important for these events as well .
There are still many questions left to be answered about this link that Clouston ’s team plans to continue studying . These let in whether the dementia experience by 9/11 survivor is biologically distinct from other types , exactly how the fine dust particles from the WTC attacks have harmed people ’s brains , and how these exposures could remain to regard the cognitive health of survivors as they get older . But there is a silver gray lining to be taken from the squad ’s employment — one that the team hopes will precede to lasting changes in how first respondent and others are equipped to deal with similar crisis situations .
“ I remember we ’ve , especially after covid-19 , become much more aware of the grandness of disguise for lots of thing . And in occupational space , some people were obviously already mindful of the benefits of masking . So the ahead - looking statement here is that more people wearing masquerade party can help . And hopefully in succeeding efforts , more people are given masks and asked to jade them , even if the air seems safe — allow ’s possibly be a little more doubting of that and wear off masks anyway , ” suppose Clouston .
