Clinical Research

Trauma and posttraumatic stress disorder (PTSD) are common in veteran and civilian populations. Meanwhile, observationally estimated half of people cared for at UW autonomic nervous system (ANS) disorder clinic have a history of trauma. Increasingly, research explains this observation through an evolving understanding of the complex interplay of peripheral and central catecholamine signaling that appear to underlie much of the persistent impact of trauma. An improved understanding of ANS changes in trauma and their relationship to the complex symptoms people experience is an important research frontiers to improve a) our understanding of PTSD, b) our ability to predict effective treatment for a given person, and c) the development of new treatments for PTSD. We propose implementing a novel analysis method for non-invasive autonomic testing in context of several clinical studies at VA Puget Sound. The proposed research aims to 1) make use of ANS testing results already available to provide quantitative data for adrenergic signaling, 2) test associations of extracted biomarkers with symptoms of PTSD, and 3) collect prospective data to test the relationship of peripheral autonomic signaling to quantitative measures of central nervous system (CNS) catecholamine signaling measured by event-related potential (ERP).
