Abstract

INTRODUCTIONThe events of September 11, 2001 at the World Trade Center (WTC) in New York, New York, USA, have been widely documented and several groups have monitored the long‐term psychiatric and disease outcomes among distinct WTC‐affected populations.1–3 Research reports high rates of chronic post‐traumatic stress disorder (PTSD)22–25 among WTC responders. WTC responders were men and women whose employment required their service or who volunteered at the site. While there, they inhaled airborne toxins, and participated in a range of high‐risk activities including, for example, digging through the rubble while looking for survivors, sifting through the debris looking for remains, or working on bucket brigades.4,5Over the past decade, studies have reported a higher than expected incidence of mild cognitive impairment (MCI),6 more rapid cognitive decline,7 and greater than age‐expected impairments in physical functioning in WTC responders.8 Recent neuroimaging work examining the reasons for these changes in WTC responders with chronic PTSD have identified reduced cortical complexity,9 and evidence of cortical and hippocampal atrophy,10,11 as well as widespread changes to the brain's connectome.12,13 These changes raised concerns that WTC exposures and related PTSD may have accelerated brain atrophy, resulting in a neurodegenerative disease that is emerging at mid‐life, 20 years after response efforts ended.12
