"Shell shock" is a term that was first used during World War I to describe a range of psychological symptoms that soldiers experienced as a result of prolonged exposure to the stress of combat. The condition was later referred to as post-traumatic stress disorder (PTSD). Symptoms of shell shock may include anxiety, panic attacks, nightmares, flashbacks, depression, and emotional numbness. The term "shell shock" is no longer used in medical or clinical settings, as it was replaced by more precise and accurate terminology.
