Post-traumatic stress disorder linked to cognitive impairment in 9/11 responders
A new study published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring of World Trade Center responders reports that post-traumatic stress disorder (PTSD) may be associated with cognitive impairment, a link previously observed in veterans. Researchers examined the connection between PTSD and cognitive impairment among 800 responders who helped with search, rescue and cleanup efforts following the 2001 World Trade Center attacks. Nearly 13 percent of study participants had scores indicative of cognitive impairment, while 1.2 percent had scores suggesting possible dementia.
