Traumatic brain injury (TBI) is a leading cause of sustained impairment in military and civilian populations. However, mild (and some moderate) TBI can be difficult to diagnose because the injuries are often not detectable on conventional MRI or CT. Injured brain tissues in TBI patients generate abnormal low-frequency magnetic activity (ALFMA, peaked at 1-4(More)
The present study developed a fast MEG source imaging technique based on Fast Vector-based Spatio-Temporal Analysis using a L1-minimum-norm (Fast-VESTAL) and then used the method to obtain the source amplitude images of resting-state magnetoencephalography (MEG) signals for different frequency bands. The Fast-VESTAL technique consists of two steps. First,(More)
The Marine Resiliency Study (MRS) is a prospective study of factors predictive of posttraumatic stress disorder (PTSD) among approximately 2,600 Marines in 4 battalions deployed to Iraq or Afghanistan. We describe the MRS design and predeployment participant characteristics. Starting in 2008, our research team conducted structured clinical interviews on(More)
A high percentage of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) combat veterans have been diagnosed with Posttraumatic Stress Disorder (PTSD) during and following their respective combat tours. Virtual Reality (VR) treatment has been documented as an exceptional treatment for anxiety disorders and specifically for PTSD. An Office of(More)
The current report summarizes a case study from an Office of Naval Research (ONR) funded project to compare the effects of virtual reality graded exposure therapy (VRGET) with cognitive behavioral group therapy in active-duty corpsmen. Details of the collaborative program between the Virtual Reality Medical Center (VRMC) and Naval Medical Center San Diego(More)
Abstract Virtual reality (VR)-based therapy has emerged as a potentially useful means to treat post-traumatic stress disorder (PTSD), but randomized studies have been lacking for Service Members from Iraq or Afghanistan. This study documents a small, randomized, controlled trial of VR-graded exposure therapy (VR-GET) versus treatment as usual (TAU) for PTSD(More)
Virtual reality (VR) is an emerging tool to help treat posttraumatic stress disorder (PTSD). Previously published studies have shown that VR graded exposure therapy (VR-GET) treatment can result in improvements in PTSD symptoms. Less is known about the impact on depression, general anxiety, and neuropsychological functioning in patients with PTSD. This(More)
OBJECTIVE This purpose of this study was to determine the incidence and types of preexisting mental disorders among military personnel who received mental health services in an Iraqi war zone. METHODS The study examined psychiatric histories of 1,078 American military personnel (Marines, 65%; Army, 23%; Navy, 11%; and Air Force, <1%) deployed to Iraq and(More)
OBJECTIVE Eye movement desensitization and reprocessing (EMDR) is one of the therapy interventions recommended by the Veterans Affairs and Department of Defense Clinical Practice Guidelines. However, the literature concerning the effectiveness of this treatment modality in military service members is sparse. This study investigated the efficacy of EMDR in(More)
This study examines the role of factors such as perceived stress, neuroticism, beliefs in psychotherapy stigma, resilience, and demographics in understanding posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) among deployed military personnel. Results show that personnel who screened positive for PTSD were more likely to screen positive for(More)
