Post-traumatic stress disorder, known as PTSD, is not just a problem for military veterans, sexual assault survivors and other crime victims — it also plagues many stroke victims, according to new research. …The new research developed from a growing awareness that medical traumas can lead to PTSD. Study leader Donald Edmondson, an assistant professor at Columbia University, previously established that PTSD is common among heart attack survivors and that it is linked to an increased risk of later developing heart disease. This led his team to question how often stroke victims develop PTSD. “For something especially acute and scary like a stroke, we wondered: Why couldn’t that be a trigger for PTSD?” said Dr. Ian Kronish, a general internist at Columbia and part of the research team.
