Investigators tested whether this intervention improves PTSD symptoms and improves quality of life. Results from this study may be used to develop a new non-medication approach to treating chronic PTSD.', 'detailedDescription': 'PTSD is highly prevalent in Veterans and is associated with significant psychiatric and medical comorbidity, as well as poor quality of life. Despite its prevalence and impact, the success of currently available treatments is mixed, highlighting the need for novel approaches that aim to reduce symptoms and improve outcomes. Prior research demonstrated that reduced activity in a part of the brain, the ventromedial prefrontal cortex (VMPFC), is associated with an inability to regulate fear responses, preventing the generation of safety memories and allowing PTSD symptoms to persist. Targeting the VMPFC with non-invasive electrical brain stimulation may therefore alleviate these symptoms.\n\nTranscranial direct current stimulation (tDCS) is a type of non-invasive brain stimulation that may enhance the likelihood of neuronal activity in the VMPFC. In doing so, tDCS prepares the brain to respond to external stimuli and to facilitate learning and memory. Because therapeutic success from exposure to trauma-related content - as used in exposure-based therapy for PTSD - is thought to be based on an adaptive learning process, applying tDCS in combination with exposure to trauma cues may effectively boost exposure-based learning. In this study, investigators at the VA Providence Healthcare System will use a standardized virtual reality (VR) setting to deliver trauma-related content. The virtual reality setting involves three, 8-minute driving scenarios, constituting one VR session, which consist of VR stimuli (sights, sounds, smells, etc.) often encountered in combat training and in theater.\n\nEligible participants will be randomized to receive six sessions of either active tDCS plus virtual reality (tDCS+VR) or sham tDCS+VR. Clinical and self-report assessments will be completed at baseline, midpoint, and endpoint, as well as 1 and 3 months following the final VR session. Primary outcome measures occur at the 1 month timepoint. Psychophysiology (skin conductance reactivity) will be collected throughout each VR session to capture habituation. Participants will also undergo a MRI before and after completion of all six active or sham tDCS+VR sessions to assess change over time. Additionally, MRI data will be used for electrical field modeling to predict treatment response based on individually obtained electrical field values in PTSD relevant neural circuitry. Participants may also choose to participate in an optional pre-active or sham tDCS+VR session EEG and an optional 1-month follow-up MRI.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Must be a Veteran\n* Located in the greater Providence and Boston areas\n* Have a diagnosis of chronic PTSD, meeting DSM-5 criteria\n* If in treatment, symptomatic despite ongoing stable treatment regimens for at least 6 weeks prior to study procedures.\n* Willing and able to comply with all study related procedures and visits\n* Capable of independently reading and understanding study materials and providing informed consent.\n\nExclusion Criteria:\n\nContraindications to MRI or tDCS, including:\n\n* Implanted device (e.g., deep brain stimulation) or metal in the brain, cervical spinal cord, or upper thoracic spinal cord.\n* Skin lesions at the site of stimulation that may increase conductance (e.g., vascular moles or angiomas)\n* Pregnancy/lactation, or planning to become pregnant during the study\n* Lifetime history of moderate or severe traumatic brain injury (TBI)\n* Current unstable medical conditions\n* Current (or past if appropriate) significant neurological disorder, or lifetime history of a) seizure disorder b) primary or secondary CNS tumors c) stroke or d) cerebral aneurysm.\n\nOther exclusions:\n\n* Primary psychotic disorder\n* Bipolar I disorder\n* Active moderate/severe substance use disorders (within the last month, excluding nicotine/caffeine)\n* Active suicidal intent or plan as detected on screening instruments or in the investigative team's judgment is likely to attempt suicide within 6 months\n* Other conditions or circumstances that, in the opinion of the investigator team, have the potential to prevent completion and/or have a confounding effect on outcome assessments."}, 'identificationModule': {'nctId': 'NCT03372460', 'acronym': 'TAVRE', 'briefTitle': 'tDCS Plus Virtual Reality for PTSD', 'organization': {'class': 'FED', 'fullName': 'VA Office of Research and Development'}, 'officialTitle': 'Combined Transcranial Direct Current Stimulation and Virtual Reality for PTSD', 'orgStudyIdInfo': {'id': 'D2450-R'}, 'secondaryIdInfos': [{'id': '2017-053', 'type': 'OTHER', 'domain': 'PVAMC IRB'}, {'id': '1633742', 'type': 'OTHER', 'domain': 'PVAMC IRB'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Active Stimulation', 'description': 'Active stimulation (tDCS) will be used in the dose of 2mA /25 min per day, for 6 sessions over the course of 2 weeks (3 sessions per week).', 'interventionNames': ['Device: Active stimulation', 'Other: Virtual Reality (VR)']}, {'type': 'SHAM_COMPARATOR', 'label': 'Sham Stimulation', 'description': 'Sham tDCS uses the device study mode (10 µA over 15 ms current pulse applied every 550 ms, 3ms peak current).
