NCT01551199
To evaluate the feasibility, acceptability and effectiveness of Multiple Channel Exposure Therapy-Veterans (MCET-V) as a treatment for returning service members with comorbid posttraumatic stress disorder (PTSD) and panic disorder (PD) in two phases. The first phase of the study will examine the feasibility and acceptability of MCET-V.
NCT02237703
This study uses positron emission tomography (PET) imaging to measure kappa opioid receptors (KOR) in the brains of individuals with and without post-traumatic stress disorder (PTSD). The investigators propose to recruit 45 drug-naïve individuals, N=15 patients with PTSD, N=15 trauma-exposed, but asymptomatic healthy control subjects (TC) and N=15 non-trauma exposed healthy control subjects (HC) to participate in one magnetic resonance imaging (MRI) and one PET study. The investigators will also carefully document trauma history, and collect behavioral and neuroendocrine measures to provide a more integrative view on the neurobiology of PTSD and its phenotype. The investigators predict PTSD will show greater carbon - 11 (11C)\[11C\]LY2795050 volume of distribution (VT) (i.e. KOR binding) values than control populations in an a priori defined PTSD circuit.
NCT00923923
Method: This study is designed as an accompaniment to an already funded study - a 12-week treatment trial with prazosin for patients with PTSD and AD. The study design will consist of III phases. In phase I, all subjects will participate in three laboratory sessions to determine their reactivity to stress. Stress reactivity will be measured using: traumatic experiences, stressful non-trauma experiences and neutral experiences, presented randomly. Laboratory sessions will be conducted in an outpatient setting. Phase II is a randomized clinical trial evaluating prazosin versus placebo for 12 weeks in a double-blind, controlled fashion in an outpatient setting. The treatment will last for 12 weeks and outcomes will include symptoms of PTSD and alcohol use. In phase III, subjects will again participate in a laboratory session. This phase of the study will be conducted after at least 6 weeks of treatment while patients are on medication (prazosin or placebo). Hypotheses: Primary: The investigators hypothesize that prazosin will be more effective than placebo in reducing trauma-related stress reactivity in a laboratory paradigm, particularly anxiety, craving for alcohol, and hormonal response, in individuals with PTSD and AD. Secondary: The investigators hypothesize that stress reactivity will have a moderating effect on treatment with prazosin, such that individuals with high levels of stress reactivity will have fewer heavy drinking days, a significant reduction in PTSD symptoms, and shorter time to relapse than individuals with low levels of stress reactivity.
