While there are many factors that can be associated with early-onset dementia, a new one is now on the radar: the 2001 terror attacks on the World Trade Center (WTC).
A recently-published paper in the JAMA Network medical journal sheds light on a concerning link between first responders and an increased risk of early-onset dementia. The study, conducted among WTC responders residing on Long Island, just outside of New York City, reveals that those with extended exposure to the toxic dust and debris are more likely to develop cognitive impairments before the age of 65. During the eight-year study more than 5,000 responders were eligible to participate and 228 people developed dementia before the age of 65.
Key findings include:
Ground Zero Exposure Increased Risk
Responders with the highest exposure levels to the dust and debris had a significantly higher risk of developing cognitive impairments, compared to those with less or no exposure. Those most at risk include rescuers who were focused on dusty locations or performing dangerous tasks around Ground Zero for at least 15 weeks. The risk dropped for rescuers who were working further away and in less dusty environments.
The study observed that for every additional month of work at the WTC site, the risk of cognitive decline increased by approximately 2%. This statistic underscores the profound impact prolonged exposure can have on brain health.
PPE Works
The use of personal protective equipment (PPE) during the cleanup efforts was associated with a reduced risk of early-onset dementia, highlighting the effectiveness of proper safety measures during exposure to hazardous conditions.
The study authors note that this important takeaway can be used to protect rescuers working on other uncontrolled building collapses and other industrial accidents.
This groundbreaking research not only adds to the growing body of literature on the health impacts of 9/11 but also underscores the long-term consequences faced by those who served during the aftermath.
