In a recent paper (Georgopoulos et al 2010 J. Neural Eng. 7 016011) we reported on the power of the magnetoencephalography (MEG)-based synchronous neural interactions (SNI) test to differentiate post-traumatic stress disorder (PTSD) subjects from healthy control subjects and to classify them with a high degree of accuracy. Here we show that the main(More)
IMPORTANCE Posttraumatic stress disorder (PTSD) and resilience reflect 2 distinct outcomes after exposure to potentially traumatic events. The neural mechanisms underlying these different outcomes are not well understood. OBJECTIVE To examine the effect of trauma on synchronous neural interactions for veterans with PTSD and resilient controls using(More)
While some trauma survivors find their faith helpful in recovery, others find it a source of distress, and still others abandon their faith. More complex conceptualizations of religious functioning are needed to explore its relationship with trauma. This study explores such relationships using measures of religious action and behaviors in a community sample(More)
OBJECTIVE The goal of this study was to assess and describe the long-term impact of traumatic prisoner of war (POW) experiences within the context of posttraumatic psychopathology. Specifically, the authors attempted to investigate the relative degree of normative response represented by posttraumatic stress disorder (PTSD) in comparison to other DSM axis I(More)
Traumatic experiences can produce post-traumatic stress disorder (PTSD) which is a debilitating condition and for which no biomarker currently exists (Institute of Medicine (US) 2006 Posttraumatic Stress Disorder: Diagnosis and Assessment (Washington, DC: National Academies)). Here we show that the synchronous neural interactions (SNI) test which assesses(More)
OBJECTIVE The purpose of this study was to evaluate levels of post-traumatic stress disorder (PTSD), depression, alcohol abuse, quality of life, and mental health service utilization among returnees from Operation Enduring Freedom and Operation Iraqi Freedom. METHODS One hundred twenty returnees, enrolled for health care at a midwestern Veterans Affairs(More)
OBJECTIVE Because findings on the mental health status of Holocaust survivors' offspring have been inconsistent, we aimed to identify factors that place some offspring at greater risk for developing mood or anxiety disorders. METHOD Using a web-based survey and structured clinical interviews with adult children of survivors, we attempted to predict(More)
OBJECTIVE The authors examined the longitudinal changes in posttraumatic stress disorder (PTSD) symptom levels and prevalence rates over a 4-year time period among American former prisoners of war (POWs) from World War II and the Korean War. Retrospective symptom reports by World War II POWs dating back to shortly after repatriation were examined for 1)(More)
American former prisoners of war (POWs) are an aging group who seek health care with increasing frequency. To examine the prevalence of long-term physical and emotional consequences of captivity in this population, the authors analyzed medical and psychiatric examination data for 426 former POWs. Detailed psychiatric diagnostic criteria were used to assess(More)
BACKGROUND Gulf War Illness (GWI) is a disease of unknown etiology with symptoms suggesting the involvement of an immune process. Here we tested the hypothesis that Human Leukocyte Antigen (HLA) composition might differ between veterans with and without GWI. METHODS We identified 144 unique alleles of Class I and II HLA genes in 82 veterans (66 with and(More)
