Changes in the Hippocampus

The hippocampus is the area of the brain that regulates happiness, joy, hunger, and it also regulates memories. Without the hippocampus, the brain would be unable to distinguish time frames for memories, as it aids in differentiating what memories took place in the past and what is happening in the present.

When PTSD occurs, the stress that takes place alters the hippocampus by killing cells, causing it to become less effective. In this weakened state, the hippocampus has trouble identifying what memories occurred in the past and which memories occur in the present. Because of this, flashbacks and memories that flood the brain cause the patient to believe that they are reliving their traumatic event.
