Emotional trauma and physical trauma can disrupt brain development and changes will occur that are negative to the brain. People traumatized by floods, fires, earthquakes have been studied and it was learned that it does change brain function.
People become fretful, anxious, and moody and often and may experience headaches, bowel problems,
and anxiety. These  conditions will create stress and kill cells in the hippocampus, one of the major memory centers in the temporal lobes. So, a victim must learn how to handle chronic stress forever or until conquered.
