Around 19 percent of Poles - almost one in five - have symptoms of post-traumatic stress disorder (PTSD), new research shows. This is much higher than the world average (approx. 5-10 percent). This is facilitated by unprocessed, transgenerational trauma dating back to World War II, explains Dr. Marcin Rzeszutek from the Faculty of Psychology of the University of Warsaw.
