Décadas después del 11 de septiembre, el polvo tóxico y el trastorno de estrés postraumático podrían estar acelerando el envejecimiento cerebral entre los socorristas

Researchers studying World Trade Center first responders report that PTSD appears linked to accelerated brain aging, with affected responders' brains scanning roughly three years older than their chronological age.

About 23% of WTC responders have been diagnosed with PTSD, compared to an estimated 6% lifetime rate in the general U.S. population, and a separate study tracking over 5,000 responders found 228 developed dementia before age 65 between 2014 and 2022.

The research ties dementia incidence to the severity of dust and debris exposure at Ground Zero, with those using protective equipment consistently faring better, a pattern researchers say may extend to responders at more recent disasters in Venezuela, Colombia, Indonesia, and Nepal.
