Shell shock, also known as combat stress reaction, was first diagnosed among soldiers during the Great War. It was a psychological condition caused by the horrors of trench warfare, including constant bombardment, gas attacks, and the loss of comrades. The symptoms included anxiety, panic attacks, tremors, nightmares, and irrational behavior. It was initially misunderstood as a sign of weakness or cowardice, but later recognized as a legitimate medical condition.
