Neurobehavioral Moderators of Post-Traumatic Disease Trajectories
Post-traumatic stress disorder (PTSD) symptoms are often observed shortly after sustaining a traumatic event. Individuals differ in the trajectory of these symptoms, leading to full, partial, or non-recovery from initial reactions. Impairments in emotional-regulatory functions that influence the processing of stressful events may contribute to the development of long-term PTSD. Neural mechanism through which these impairments mediate the impact of trauma may include hyperactive emotional reactivity coupled with dysfunctional regulatory circuitry. Studies to date have yet to longitudinally explore the neural mechanism of PTSD symptom trajectories over the first year after trauma exposure. In my PhD research, we aim to prospectively probe specific components of the stress response network in trauma-exposed individuals during 14 months following the traumatic event, tracking both symptomatic development, the underlying brain plasticity, and putative brain tissue of function vulnerability factors. Within the study, subjects are assessed shortly after being admitted to Emergency Department following potentially traumatic events and are subsequently evaluated at three time points (one, six, and fourteen months from the trauma), for trauma-related symptoms and contemporaneous brain functions and structures. The combination of behavioral symptoms, specific brain functions and brain structures, and their time-dependent progression, may identify potential targets for preventive neurocognitive intervention for PTSD.
