Terror has been the most merciless and scary method of a fight in the history of humankind. During the post-attack, people go through anxiety disorder and trauma which threaten their physical and psychological integrity. Due to the trauma that is called the state of timelessness, causing victims to lose touch with both the past and the future, they cannot perform the daily responsibilities, suffering the functionality disruption in their family, school, business, and social lives.

Millions of people watched September 11 terrorist attacks on TV; the moment the planes crashed into the World Trade Center, the collapse of colossal buildings and the victims who jumped 400 meters off the building in an attempt to avoid the fire, eventually falling on the ground. The visual and auditory images of those horrific scenes have still kept haunting the mind.

The definition of terror, the September 11 terror attacks, psychological impacts of terrorism, remedial therapy and two case summaries on treatment by the EMDR therapy during Post-September 11 terrorist attacks are provided in this study.
