This study indicates that elephants suffer from post-traumatic stress disorder, which in humans causes depression, nightmares and anxiety, the traumatic experiences they have suffered previously.

Thus, flocks of these mammals have assaulted people, demolished huts and destroyed crops, not for food as they did in the past, but to scare people.
