Filter by:Post-traumatic stress disorder, PTSD, is one of the most prevalent psychiatric disorders. As casualties of motor vehicle accidents, criminal acts or terrorism are arriving to the ER, it is almost impossible to conclude who will overcome his psychiatric trauma and will be able to return to his normal life course and who will be thrown out of his promising life trajectory. Current attempts to identify those who are at the greatest risk are still unsatisfactory, which comprise a therapeutic dilemma, since the interventions used to ameliorate and prevent the occurrence of PTSD in a high-risk patient, might be counter-productive and even precipitate the emergence of PTSD in lower-risk patients. Since PTSD is closely related to the "Fight, Flight or Freeze" reaction, it has much to do with the autonomic nervous system and the major stress hormone, cortisol. Despite many studies demonstrating the involvement of those factors in the development of PTSD, various attempts to profile the direction of the association between PTSD and cortisol abnormalities have yielded conflicting results. The introduction of a novel method of assessing the excretion of cortisol using residues in the human hair shaft, has allowed an unprecedented evaluation of its activity over a prolonged period of time. Using this novel method of cortisol assessment, the investigators aim to identify biomarkers that will be able to aid in the prediction of PTSD development ahead of symptoms emergence, and will enhance the understanding of the physiological mechanism involved and etiology of this disorder.
The purpose of this study is to explore the effectiveness of adding lithium carbonate (lithium) to treatment for combat-related post traumatic stress disorder in combat veterans. The goal of this study is to establish that lithium is a practical and tolerable treatment option for veterans with combat posttraumatic stress disorder.
It has been suggested that N-acetylcysteine exerts neuroprotective effects by regulating neurotransmitters and cell signaling pathways. We hypothesize that oral N-acetylcysteine augmentation will help reduce symptoms in patients with posttraumatic stress disorder as well as improve cognitive functions. We also expect that the N-acetylcysteine augmentation will induce change in structural, functional, and neurochemical aspects of the brain. In this study, we plan to conduct a randomized, double-blind, placebo-controlled augmentation study with N-acetylcysteine in addition to escitalopram. We will assess the efficacy and safety of the N-acetylcysteine augmentation.
The purpose of this study is to determine whether deep brain stimulation of the basolateral nucleus (BLn) of the amygdala, on both sides of the brain, can safely reduce symptoms of post-traumatic stress disorder (PTSD) in combat veterans whose condition has not improved despite extensive treatment with currently available medication and psychotherapy interventions.
The investigator proposes to examine treatment for Posttraumatic Stress Disorder for Veterans who served in Iraq and Afghanistan provided through telemedicine which connects patients to doctors in different locations using the internet. In this study, Veterans will receive prolonged exposure therapy (PE). This treatment has been shown to be effective in reducing PTSD symptoms. For this study 9 weekly 90 minute sessions will be given over a period of up to 3 months. The first 2 sessions of each treatment will involve education, rational and treatment preparation. Sessions 3-9 will consist of recounting the traumatic event out loud and repeatedly. The purpose of this study is to determine if this treatment is effective when given through telehealth. To this end, the investigators propose to enroll up to 20 individuals who will access the investigators services through the GA telehealth network who has hundreds of telehealth sites across the state of Georgia. Patients will go to these sites to access the investigators therapists using GA telehealth equipment. The investigators hypothesize that PE delivered remotely through telemedicine will work to reduce the symptoms of PTSD.
Background: - Some people who have a traumatic brain injury (TBI) recover completely. Others, however, develop post-traumatic stress disorder (PTSD), with anxiety and depression. Research suggests that levels of a brain chemical called GABA may differ in people with PTSD compared to those without PTSD. Researchers want to see if TBI can affect GABA in the brain and help develop PTSD. To look at the brain, researchers will use imaging studies with the chemical 11C-Flumazenil, which will help the scan show GABA levels in the brain. Objectives: - To study the relationship between PTSD and TBI. Eligibility: The subjects will be recruited from the Walter Reed National Military Medical Center (WRNMMC). - Individuals between 18 and 50 years of age who have PTSD and/or had a mild TBI. - Healthy individuals between 18 and 50 years of age who have no history TBI and no history of PTSD. Design: - Participants will be screened with a physical exam and medical history. Urine and breath samples will also be collected. - Participants will have two imaging studies, on the same day if possible. The first will be a magnetic resonance imaging scan to look at the brain. The second will be a positron emission tomography scan with the study chemical to look at GABA pathways in the brain....
The objective of this study is to evaluate whether use of TRMDU in addition to medication review leads to improved outcomes and reduced health care costs for patients when compared with medication review alone. The study will be conducted in patients assigned to Department of Defense (DOD) Warrior Transition Units (WTU's), similar DOD units, and VA polytrauma centers.
This study will be an 8-week randomized, placebo-controlled clinical trial of pregnenolone administered adjunctively to treatment as usual in PTSD and depression in OEF/OIF Veterans.
In this study, the investigators are looking at how PTSD affects things such as memory, attention, reaction to sounds, eye movements, and heart rate. The investigators are also studying whether a medication called prazosin has an effect on these things.
Chronic posttraumatic stress disorder (PTSD) is a debilitating disorder and treatment response to pharmacological interventions has been modest for these patients. Chronic elevated anxiety and associated psychophysiological parameters including increased heart rate and alterations in skin conductance are key symptoms of chronic PTSD. Antidepressants, including selective serotonin reuptake inhibitors (SRIs) or norepinephrine-serotonin re-uptake inhibitors are considered treatment of first choice for these patients, however a substantial portion of patients do not respond sufficiently (Zhang and Davidson 2007). Therefore, there is a need to establish novel and effective add-on treatment strategies for these patients. Recently, atypical neuroleptics have received considerable attention since it was shown in multiple controlled and naturalistic trials that these medications are an effective treatment option for patients with PTSD (Davis et al 2006). In chronic PTSD, the psychophysiological responses at baseline and in response to treatment have yet been inadequately studied and may provide novel insight into antidepressant and anxiolytic mechanisms of medications used in the treatment of PTSD. Therefore, in addition to evaluating the antidepressant and anxiolytic effects of paliperidone, a novel atypical neuroleptic, in the treatment of PTSD, we also aim to compare neurophysiological responses at baseline with post-treatment effects in antidepressant-refractory PTSD patients. Primary Aim 1: Evaluate the anxiolytic and antidepressant effects of paliperidone in patients with PTSD. Secondary Aim 2: Evaluate the effects of paliperidone on fear conditioned psychophysiological responses (including startle eyeblink, skin conductance, and cardiovascular inter-beat interval) at baseline and after 6 weeks of naturalistic treatment in chronic PTSD patients.
