Really depends on the trauma, the person and the environment. I think this is an ongoing field of study in neuroscience.
Using PTSD as an example. A traumatic event (or multiple events), leaves the brain stuck in fight or flight mode. The hormones that trigger this response can impact the structure of the brain over time. Studies have found that the size of certain parts of the brain related to stress are different in some people with PTSD.
