Psychological trauma is very common, understudied and consequently undertreated in Greece and many other countries. The word trauma comes from the Greek trauma (τραύμα) meaning trauma wound, alteration of trōma; akin to Greek titrōskein = to wound, tetrainein = to pierce. Although there is no data available on the prevalence rates of trauma or posttraumatic stress disorder (PTSD) in Greece, there is no reason to believe that various types of traumatic experiences are not common phenomena in Greek society.
