The Center will be among the first to study how traumatic stress can lead to illness. It will study how traumatic stress can cause depression, and anxiety. The Center will also look at the ways that stress can affect medical care. We plan to study many different people. We plan to study the young and old. We also will study people from different backgrounds. Then we will look at the ways these people are alike and different when it comes to coping with trauma. By studying these people we can help everyone get better medical care.
