Filter by:In the present study, investigator will investigate the effects of methylphenidate (40 mg) on mPFC activity in healthy male volunteers during fear extinction using functional magnetic resonance imaging (fMRI). Additionally, investigators will examine the effects of methylphenidate during aversive interoceptve arousal. The present study will help to identify brain structures and networks involved in anxiety and will give insights for methylphenidate as a possible adjunct to behavioral therapy for patients with anxiety disorders. Further, this study may provide important information about the possible use of fMRI to help the development of drugs for the treatment of anxiety disorders.
This open label study will evaluate the safety and efficacy of riluzole in patients with PTSD. Patients will receive riluzole 50mg twice per day orally for 12 weeks as outpatient, with a one month follow up at week 16.
The purpose of this study is to evaluate the effects of treating Obstructive Sleep Apnea (OSA) with continuous positive airway pressure (CPAP) therapy on symptoms of post traumatic stress disorder (PTSD). The study hypotheses are that CPAP use will improve PTSD symptoms overall and that CPAP use will improve sleep quality and duration, nocturnal symptoms related to PTSD, mood, daytime sleepiness, sleep-related quality of life, and general health perception.
Background: A traumatic brain injury (TBI) could mean a person is at high risk for other long-lasting problems. These problems could include post-traumatic stress disorder (PTSD), depression, and post-concussive syndrome (PCS). For example, about 700,000 Americans each year who have a TBI later go on to have PTSD also. Depression and PCS are also common in people who had a TBI. Some people will have these problems later. These problems can seriously interfere with a person s life. Some people will not have these problems at all. There are many reasons for this difference. Researchers think the main reason is that people have different genetic and environmental influences. Right now, we only have few kinds of treatments to prevent or treat these problems after a TBI. The few treatments we have often do not work well. It is important to understand what factors make a person at high risk for these problems after a TBI. This could allow researchers and doctors to help address these problems early. Addressing these problems earlier may help a person have better health in the long run. Objectives: - To study the biological changes that happen after mild to moderate TBI which could be linked to the onset of PTSD, depression, and post-concussive syndrome - To study brain mechanisms that could explain risks for getting a psychiatric disorder after mild to moderate TBI. This will be done using a test called functional MRI (fMRI). This test takes images of the brain while a person is doing a simple task. Eligibility: - Men and women who are 18 to 65 years old. - Had a mild to moderate TBI (including concussion) in the last month. Design: - 5 outpatient visits to the NIH Clinical Center over one year. - The first visit is a screening visit to see if you can join the study. This visit must happen within 30 days of the TBI. The visit includes lab work (blood and urine), a history and physical exam done by a physician or nurse practitioner, and a psychiatric interview with a behavioral health nurse. - Visits 2, 3, 4 and 5 happen at one, three, six and twelve months post-injury. At these visits participants may have some or all of the following tests: blood and saliva collection, urine collection, questionnaires and interviews to assess symptoms, a test to see your response to stress (called hydrocortisone challenge), and fMRI brain imaging. - This study does not provide treatment. - This study is not a substitute for seeing a primary care provider. - This study should not replace any therapies you may be taking.
Treatment for veterans who have had a traumatic brain injury (TBI) and who are suffering from post traumatic stress syndrome (PTSD) is varied with varied outcomes. Investigators will study PTSD treatment in military Veterans who have suffered traumatic brain injuries. Investigators will use 1 independent specialty treatment centers that utilize a specific novel methodology of PTSD treatments and study the clinical outcomes of veterans who have suffered a TBI with associated post-concussive symptoms and other comorbidities such as PTSD. Investigators hypothesize that the treatment of PTSD will have a significant outcome with neurological physical and vestibular rehabilitation when compared to psychological or psychiatric therapy. This study will use gold standard measurement scales and compare changes in the scales after treatment to evaluate the treatments.
The purpose of this study is to examine whether behavioral activation as an adjuvant to standard smoking cessation treatment improves smoking cessation outcomes among veterans with PTSD relative to a comparably intense combination of standard smoking cessation treatment + health and smoking education. It is expected that behavioral activation will produce more successful results than health and smoking education when paired with standard smoking cessation treatment.
The primary goal of the study is to evaluate the use of a new smart phone application in preventing relapse to smoking among people with PTSD. The technology intervention will combine a mobile system to reward non-smoking, smoking cessation counseling, smoking cessation medications, and use of the smart phone app. The primary aim is to evaluate how effective this intervention is in preventing smoking relapse compared to another intervention that does not include the app.
Evidence from preliminary studies suggests that people with PTSD have heightened fear responses and that cortisol suppression reduces this heightened fear. Research has shown the drug dexamethasone (DEX), a cortisol suppressor, reduces the startle response in civilians with PTSD. This current research proposal represents a blinded, randomized, placebo-controlled efficacy study with the goal of determining whether a drug that suppresses the stress hormone cortisol will increase the efficacy of exposure therapy. Specifically, it is proposed that a dose of DEX, given the night before (approximately 10 hours before) each of 5 to 11 individual virtual reality exposure (VRE) therapy sessions, will significantly enhance the rate of response and possibly the efficacy of treatment. Participants will be treated until they have experienced at least a 70% reduction in PTSD symptoms from baseline or up to 12 sessions or until they and their therapist agree treatment should be terminated, a minimum of 6 sessions to a maximum of 12 sessions. Comprehensive multi-modal outcomes will be assessed by independent assessors blind to subject condition on interviews, self-report measures, and psychophysiological measures. Participants will be assessed pre- and post-treatment and at a follow-up of 3, 6 and 12 months to assess long term effects.
The purpose of the study is to use fMRI to investigate amygdala response to fearful faces in men and women with and without PTSD who have experienced childhood trauma. The study will also compare the effects of oxytocin and placebo on amygdala response, and explore the interaction of oxytocin plasma levels and amygdala response in men and women with and without PTSD who have experienced childhood trauma. Hypothesis 1: Amygdala responding will be greater in subjects with PTSD as compared to resilient subjects, and no sex differences in the magnitude of the response will be found. Hypothesis 2A: In response to OT, women will exhibit a greater reduction in amygdala responding than men. Hypothesis 2B: In response to OT, women with PTSD will exhibit a greater reduction in amygdala responding compared to women without PTSD. Hypothesis 3A: Women with PTSD will have lower levels of plasma OT as compared to men with PTSD, and women and men without PTSD. Hypothesis 3B: Plasma OT levels will be inversely correlated with amygdala responding to fearful faces in women but not in men.
The aim of this randomised controlled trial is to study two types of physical activities as add-on treatment, compared to treatment as usual for traumatised refugees. Hereby, the study will examine the evidence of an often-used treatment modality in a field where very little research yet has been conducted.
