How long has the term ptsd been used?

Post-traumatic stress disorder (PTSD) is a mental health condition that can occur after a person has experienced or witnessed a traumatic event. The symptoms of PTSD can include flashbacks, nightmares, difficulty sleeping, irritability, and difficulty concentrating.

The term PTSD was first used in the 1970s to describe the symptoms that Vietnam War veterans were experiencing. However, the concept of PTSD has been around for much longer. In the 19th century, PTSD was known as "shell shock" or "battle fatigue." In the early 20th century, it was known as "traumatic neurosis."

The term PTSD was officially adopted by the American Psychiatric Association in 1980. It is now used to describe the symptoms that can occur after a person has experienced or witnessed a traumatic event.
