What's in a name? Researchers track PTSD's many identities during war -- ScienceDailyThe paper revealed that PTSD symptoms were known as shell shock during World War I, and irritable heart or soldier's heart during World War II. The term gross stress reaction was introduced in the first edition of the Diagnostic and Statistical Manual in 1952, but was omitted in a second edition in 1968 during the Vietnam War. It wasn't until 1980, with the publication of the manual's third edition, that the term PTSD was introduced to describe military trauma and non-war related factors, such as sexual abuse. "PTSD has existed forever," Chekroud said. "It's just a question of what we've been calling it." Chadi Abdallah, MD, Assistant Professor of Psychiatry at Yale and the editor of Chronic Stress, said the history of disjointed terminology resulted in a 60-year delay in understanding traumatic symptoms experienced by veterans and others.
