31 Clinical Trials for Various Conditions
The goal of this clinical trial is to use psychophysiological methods to test the effects of a message source (expert and peer) and message presentation types (one-sided and two-sided) to identify the optimal message type for young adults who vape and do not vape.
The purpose of this research is to study the effects of nasal oxytocin administration on maternal behaviors that may be influenced by cocaine use during pregnancy. 32 mothers with prenatal use of cocaine during the current pregnancy will be studied at 3-6 months postpartum, when they will complete 3 study visits, a 2-week double-blind trial of twice daily nasal spray (oxytocin or placebo) and 4 telephone interviews. All information collected is confidential.
The Wisconsin Center for the Neuroscience and Psychophysiology of Meditation will be a highly focused center dedicated to novel and cutting edge research on the mechanisms by which meditation works. The core set of hypotheses for this Center focus on the mechanisms of two common meditation practices: Mindfulness Meditation (MM) and Loving-Kindness/Compassion Meditation (LKM-CO), both taught in Mindfulness-Based Stress Reduction (MBSR). The investigators will study both Long-Term Meditators (LTMs) as well as meditation-naïve participants (MNPs). The latter group will be randomly assigned to MBSR, a rigorously matched comparison intervention called the Health Enhancement Program (HEP; MacCoon et al., 2012), or to a Wait List (WL) control group. This will give us a comprehensive view of changes that are produced by meditation practices per se, changes generically associated with interventions designed to promote well-being, and changes that might be effects of repeating testing protocols across multiple occasions. In addition, the inclusion of both novice and experienced meditators provides a wide range of practice experience that will provide critical information on dose-related effects, information that is lacking in the research literature today. Each of the projects is focused on examining the brain mechanisms and peripheral biological correlates of meditation. Project 1 (Davidson) will examine the impact of the explicit use of mindfulness and loving-kindness/compassion strategies on emotion regulation, specifically neural, biobehavioral and hormonal indices of reactivity to and recovery from pictures of human suffering and flourishing. Project 2 (Rosenkranz) will investigate the brain to periphery pathways through which psychological factors contribute to the expression of asthma symptoms. In addition, it will examine the efficacy of meditation training in reducing the inflammatory response to an allergen in asthmatic individuals by reducing the reactivity of emotion-related neural circuitry. Project 3 (Tononi) will examine whether the previously reported increase in gamma oscillations during Non-REM (NREM) sleep in meditators is associated with changes in sleep mentation (Ferrarelli et al. 2013). In addition, project 3 will examine relations between meditation-induced changes in brain activity during sleep and brain activity and cognitive function during wakefulness.
The purpose of the study is to understand the biology and behavior of early mother-infant attachment, and to investigate how it may be affected by prenatal substance exposures. The investigators are interested in how drugs such as cocaine, alcohol, marijuana and cigarette smoking affect both mother and baby.
Prenatal Mindfulness training (MT) shows promise as a preventive intervention against hypertensive disorders of pregnancy (HDP) and may reduce risk for offspring cardiovascular disease (CVD). One proposed mechanism of MT to reduced CVD risk is improved self-regulation following stress. Perhaps the most crucial contributor to the development of self-regulation in the first year is the psychophysiological coregulatory relationship between mother and infant. However, this self-and co-regulation among women exposed to prenatal MT has not been studied and has yet to be examined in relation to CVD risk. The goal of this proposed project is to evaluate maternal-infant physiological reactivity to and recovery from stress at 6 months postpartum following prenatal MT, and to examine the relationship between these maternal infant stress responses and maternal-infant CVD risk at 12 months postpartum. Using a lab-based stress paradigm and well-validated biomarkers of mother and infant CVD risk, the investigators will assess respiratory sinus arrhythmia and heart rate at 6 months postpartum for 40 mother-infant dyads who have completed either prenatal MT or a usual care arm of an RCT examining MT for women at risk for HDP. The investigators will compare maternal, infant, and dyadic stress responses by treatment arm. Then, cardiac stress responses will be examined as predictors of maternal and infant biomarkers of CVD risk at 12 months postpartum.
Alzheimer's Disease (AD) and Alzheimer's Disease-Related Dementias (ADRD) not only exact a heavy toll on patients, they also impose an enormous emotional, physical, and financial burden on unpaid, often family, caregivers. The strain of providing care for a loved one diagnosed with AD, often across several years, is associated with elevated depression risk and poorer overall health. Emotion regulation skills represent an ideal target for psychological intervention to promote healthy coping in ADRD caregivers. The project seeks to use an experimental medicine approach to test the efficacy and biobehavioral mechanisms of a novel, relatively brief, targeted, scalable, smartphone-based cognitive emotion regulation intervention aimed at improving psychological outcomes (i.e., reducing perceived stress, caregiver burden, and depressive symptoms) in ADRD unpaid primary caregivers as well as examine potential benefits of the caregiver intervention on quality of life in care recipients. Cognitive reappraisal is the ability to modify the trajectory of an emotional response by thinking about and appraising emotional information in an alternative, more adaptive way. Reappraisal can be operationalized via two primary tactics: psychological distancing (i.e. appraising an emotional stimulus as an objective, impartial observer) and reinterpretation (i.e., imagining a better outcome than what initially seemed apparent). The project will investigate the efficacy and underlying biobehavioral mechanisms of a novel, one-week cognitive reappraisal intervention in this population, with follow-up assessments at 2 weeks, 4 weeks, and 3 months. ADRD unpaid primary caregivers will be randomly assigned to receive training in either distancing, reinterpretation, or a no regulation natural history control condition, with ecological momentary assessments of self-reported positive and negative affect, remotely- collected psychophysiological health-related biomarkers (i.e., heart rate variability data) using pre-mailed Polar H10 chest bands, and health-related questionnaire reports. Distancing training is expected to result in longitudinal reductions in self-reported negative affect, longitudinal increases in positive affect, and longitudinal increases in HRV that are larger than those attributable to reinterpretation training and no-regulation control training.
The goal of this study is to examine attentional biases for facial displays of emotion as a mechanism of risk in infants of mothers with postpartum major depression, and the potential role of infant arousal in the development of these attentional biases.
The goal of this clinical trial is to investigate how the friendship experiences of maltreated (i.e., abused and/or neglected) and non-maltreated adolescents differentially influence their risk for adverse outcomes. The main questions it aims to answer are: 1. How do the friendships of maltreated adolescents differ from those of non-maltreated adolescents? 2. Which friendship experiences influence the associations between maltreatment and ability to regulate stress, as well as future mental health difficulties and revictimization? Participants will: * Attend the initial study visit on the campus of the University of South Carolina with their primary caregiver and a best friend during which they will: * Complete study questionnaires * Be connected to a device that records their physical ability to manage stress * Complete a task during which they will be audio and video recorded and complete a brief assessment rating how they are feeling at different times during task completion * Depending on which research group they are placed in, be assigned to discuss their experience doing this task with their friend (intervention group) or sit quietly in a room for 5 minutes (comparison group) * The follow-up study visit will involve completion of study questionnaires online or via mail 6 months later Additionally, the participant's caregiver and friend will complete study questionnaires. Researchers will compare the intervention group (debriefs with a friend) and comparison group (sits quietly for 5 minutes) to see if the presence of and discussion with the friend influences their physical ability to regulate stress and future outcomes.
Interested individuals will first complete a telephone screening followed by a series of structured clinical interviews to diagnose PTSD and comorbid psychiatric disorders, confirm initial inclusion criteria, rule out exclusion criteria and create an audio-recorded account of their index trauma. Participants passing screenings will then complete 2 weeks of at-home sleep and nightmare diaries and time-stamped audio-recorded reports of dream content upon awakening from any nightmare. They will also wear a wrist actigraph throughout this period, complete 2 nights of ambulatory PSG, and complete on-line questionnaires. Nightmare data will be examined for frequency and thematic similarity of nightmares to a participant's reported index trauma. Participants' nightmare and index trauma reports will be audio-recorded for use as scripts during SDI. The participant will then undergo two SDI sessions on a single day, one with a nightmare script and one with an index-trauma script, during which they will wear the NINscan. Sessions will be separated by 1 hour and counterbalanced across participants for script order.
The MiSBIE study collects biological, behavioral, psychosocial, neuropsychological, and brain imaging data in participants with either: normal mitochondrial function, individuals with the m.3243A\>G mitochondrial DNA (mtDNA) mutation, and individuals a single large-scale mtDNA deletion. These defects induce mitochondrial allostatic load (MAL). The 2-day protocol, plus home-based data collection, will provide a comprehensive assessment of the multi-systemic dysregulation associated with MAL or mitochondrial dysfunction, and the link to physical and mental health-related symptoms. Aim 1: Determine the influence of MAL on systemic AL biomarkers. Aim 2: Establish the influence of MAL on stress reactivity profiles. Aim 3. Examine the association between MAL and psychological functioning.
The primary objective of this study is to assess acquisition and retention of a Cognitive Behavioral Therapy (CBT)-based "cognitive restructuring" skill, among young adolescents (12-15 years of age) with elevated depression symptoms and with population-level variability in lifetime exposure to adverse childhood experiences. This study uses a repeated-measures, longitudinal design to investigate associations between adversity exposure and learning-related cognitive control processes in the context of elevated depression (Aim 1). Adversity exposure and cognitive control will be examined as direct predictors of cognitive restructuring skill acquisition and skill retention over six-months; an indirect pathway from adversity to skill acquisition through cognitive control will also be examined (Aim 2). The study also includes exploration of key characteristics of adversity, namely the type (threat of harm versus deprivation of resources) and developmental timing of exposure, as distinct predictors of skill acquisition (exploratory Aim 3).
The study will (1) assess feasibility of a TMS treatment in an underserved population; (2) determine if this TMS treatment protocol improves PTSD symptoms and biological markers of PTSD such as brain functioning and startle responses; (3) define new brain targets for future TMS studies; (4) provide the first data for individual differences, which will help personalize treatment for PTSD patients; (5) improve knowledge of the neurobiology of PTSD and treatment response.
The purpose of the study "Stress, Emotion Regulation, and Alcohol in Women Veterans" is to learn about the effects of negative emotion and stress on behavior (including alcohol use) among women Veterans, including women with and without posttraumatic stress disorder. Additionally, the study looks at whether a woman's use of emotion regulation techniques changes the association between stress or negative emotion and behavior. Lastly, the study examines how women's reactions to stress, and the effects of stress, vary across the menstrual cycle - depending on the level of circulating hormones.
Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition that disproportionately affects Veterans. Prolonged Exposure (PE) therapy is a "gold standard" treatment for PTSD. However, approximately one-third of Veterans fail to receive an adequate dose of treatment because they prematurely drop out of PE therapy. There is also room to improve PE treatment outcomes. Consistent with the VA Office of Research and Development initiative to develop effective treatments for PTSD, the proposed randomized clinical trial will examine the ability of oxytocin (as compared with placebo) combined with PE to reduce PTSD symptom severity, improve the rate of PTSD symptom reduction, and to enhance PE treatment retention and adherence. This two-site study will leverage the investments made in the nationwide rollout off PE therapy and has the potential to significantly improve mental health care among Veterans, advance the science in this area, and identify mechanisms underlying positive PTSD treatment response. Participants may choose to complete this research study via home-based telemedicine (HBT) care (i.e. service delivery to patients in their homes using consumer friendly, video-conferencing technology). HBT sessions will be delivered via standard desk, laptop computer, tablet, or smartphone using VA approved applications. All procedures that take place via telemedicine will be performed and completed as though they were in-person/in-office
1. PURPOSE OF THE STUDY 1.1 Justification The purpose of the project is to examine the effect of breathing biofeedback and thoughts about stress on performance under stress and cigarette cravings. Smoking rates in the United States have been steadily going down over the past 50 years, and now 16.8% of adults smoke (Centers for Disease Control and Prevention, 2015). Most smokers try to quit, but end up going back to smoking (Garcia-Rodriguez et al., 2013; Piasecki, 2006; Rafful et al., 2013). The reasons people go back to smoking may have something to do with stress in their lives, particularly for women who smoke. This study wants to see if we can reduce temporary stress and lower craving to smoke after stress. 1.2 Description of the Research Project Approximately 60 adult women will participate in the study. Participants must be between 18 and 65 years old, able to read English fluently, and must agree to engage in the research procedures (stress protocol, physiological assessment, breathing training, questionnaires) to participate. People who are taking medications that interfere with physiological assessment are excluded from participating including people with: self-identified substance use problems, self-identified psychosis, morbid obesity (BMI\>40), and people who take anti-cholinergic medication, beta blockers, Ritalin, benzodiazepines, tricyclic antidepressants or bupropion, varenicline, antipsychotic medication, or nicotine replacement therapy. People who have a cardiac rhythm abnormality or major neurological problem are also excluded from the study. Also, participants may not participate if they are pregnant or color-blind. Participation is strictly voluntary. 2. PROGRESSION OF THIS STUDY 2.1 Procedures The study visit procedures will take place at the Emotion and Psychopathology Laboratory at Rutgers University, located at the Rutgers Institute for Health, Healthcare Policy, and Aging Research. Participants will first complete some questionnaires and provide some basic information about themselves (demographic information, responses to emotion and stress, and smoking history). Next, participants will engage in a baseline psychophysiological assessment where investigators will examine heart rate, breathing, and blood pressure. Next, investigators will either ask participants to sit quietly for 30 minutes while completing a computer task and watching short videos, or practice a specific deep breathing exercise for 30 minutes. Then participants will do three tasks on a computer. The tasks will ask participants to trace different shapes, answer math problems while receiving feedback about how they're doing, and identify colors and words on a screen. Finally, participants will be asked to sit quietly for 15 minutes before investigators remove the psychophysiological recording equipment. One week after the study visit, investigators will contact participants via phone to ask them some questions about the study visit. 2.2 Duration of the study This study visit will last approximately 3 hours. Length of the visit may vary because each individual may complete procedures at a different pace. The phone call after the study visit will last approximately 10-15 minutes.
This study will investigate the effects of intranasal administration of oxytocin, a social neuropeptide, on reducing stimulant use, enhancing therapeutic engagement, and susceptibility to stress-induced relapse in Veterans with stimulant use disorders and enrolled in opioid replacement therapy (ORT) program for co-occurring opioid use disorder (OUD).
Will a primary care-based behavioral intervention for patient activation and engagement and self-management, for patients with chronic pain who are taking opioid pain medication, result in better patient outcomes than Usual Care?
Background: - Scientists know that alcohol use disorders affect brain structure. They want to know more about the effects of alcohol use disorders on a person s behavior. They want to develop tasks that can be done inside a scanner that can help them better understand these effects in later studies. Objective: - To develop tasks that investigate a person s behavior that can be used in later studies. Eligibility: * Inpatient participants of another study. They must be physically healthy right-handed adults 18-60 years old. * Healthy right-handed volunteers 18-65 years old. Design: * Participants will be screened with medical history and physical exam. They will have an EKG to record heart activity. They will give blood and urine samples and have a psychiatric interview. * Participants will have between one and three visits. * Participants will be asked about their alcohol drinking to see if they have an alcohol use disorder. * Participants will complete one of three simple computerized tasks either inside the magnetic resonance imagining (MRI) scanner or outside of it. * The MRI scanner takes pictures of the brain. The scanner is a metal cylinder. Participants lie on a table that can slide in and out of the cylinder. They will be in the scanner for about 60 minutes. They may have to lie still for up to 20 minutes. The scanner makes loud knocking noises, but they will get earplugs.
The central aim of this study is to assess mother-infant communication via behavioral, physiological, and affective indices under conditions where distal stressors may not be directly detectable by the infant.
Despite substantial therapeutic advances, Posttraumatic Stress Disorder (PTSD) remains difficult to treat. One promising new area of research is in post-reactivation pharmacologic intervention, which is based upon the concept of blockade of memory reconsolidation. Recent animal research suggests that reactivation (retrieval) of a stored memory can return it to a labile (alterable) state from which it must be restabilized in order to persist. This process is called "reconsolidation," and various drugs have been found to block it in animals. This blockade may lead to a weakening of the original memory trace. The aim of this study is to pilot the effect of mifepristone on physiologic responding during traumatic imagery. Although mifepristone is widely and safely used to cause a medical abortion, it is also a powerful stress hormone receptor blocker. These stress hormones, called glucocorticoids, may enhance memory (re)consolidation. Indeed, a recent study in animals reported that mifepristone blocked reconsolidation of context-conditioned fear in rats. Reconsolidation blockade is a two-stage process. First, the memory must be destabilized by recalling it. Second, reconsolidation of the memory must be blocked by a drug. Memory traces formed under stressful conditions may resist destabilization and thus are inaccessible to reconsolidation blockers. However, when a reconsolidation blocker was paired with d-cycloserine (DCS) in animals that had been trained under stressful conditions, reconsolidation blockade became successful. These results suggest that DCS promotes the destabilization of resistant memory traces. The traumatic memories of individuals with PTSD may be particularly resistant to destabilization. Therefore, this study will compare mifepristone paired with DCS to placebo controls. The same script-driven traumatic imagery method validated in previous studies of propranolol in this lab will be used. Briefly, subjects with PTSD will describe their traumatic event during a script preparation session, which will reactivate the memory. They will then receive a) mifepristone and DCS or b) placebo. A week later, they will engage in script-driven mental imagery of their traumatic event while physiologic responses (heart rate, sweating, etc) are measured. This is a pilot study so there are no formal hypotheses. The aim is to estimate effect sizes for mifepristone and to compare them with effect sizes for propranolol from this lab's previous work.
The proposed study has three distinct but related research objectives. The first goal is to measure physiological correlates of successful treatment with Prolonged Exposure (PE) therapy for posttraumatic stress disorder (PTSD) in veterans of the Iraq and Afghanistan wars. Individuals with PTSD often experience elevated heart rates and other objectively measurable signs of anxiety when confronted with safe situations that remind them of past dangerous situations. We will measure physiological responses and compare the outcomes to patient's self reported subjective accounts of symptom improvement on traditional measures of PTSD. Developing a way to measure objective gains in symptoms improvement may help researchers who are studying ways to improve PTSD treatment. The second goal of the study is to investigate if yohimbine, a drug found to promote a specific type of learning, will improve treatment outcomes for veterans in PTSD treatment. The third goal is to investigate if ability to get used to loud startling audio tones correlates to baseline PTSD pathology and treatment outcomes for PE. This goal represents an important step forward in understanding characteristics of heritable traits that are related PTSD. It is significant because such research may one day lead to the development of individual responder policies that will assist patients by individualizing treatment plans based on personal characteristics.
The consolidation of learning is enhanced by adrenalin and other stress hormones. This memory enhancing effect is opposed by propranolol. In posttraumatic stress disorder (PTSD), a psychologically traumatic event may overstimulate stress hormones such as adrenalin, which in turn overly strengthen consolidation of the memory of the event, leading to an excessively powerful and persistent memory. Administration of propranolol after a psychologically traumatic event could reduce subsequent PTSD. Unfortunately, there exists a window of opportunity for influencing the consolidation of a traumatic event into long-term memory. In persons who have already developed PTSD, this would have closed months or years earlier. However, recent developments in animal research suggest that reactivation (retrieval) of a consolidated memory can return it to a labile state, from which it must be restabilized in order to persist. This process, which has been termed "reconsolidation," can be reduced in animals by propranolol. In a preliminary study performed by the PI and colleagues in Canada, civilian participants with PTSD described the traumatic event during a script preparation session, which served to reactivate their traumatic memory. They then received either propranolol or placebo. A week later, during script-driven imagery of their traumatic events, physiologic responses were smaller in the participants who had received post-reactivation propranolol compared to placebo, suggesting that the traumatic memory had been weakened by the propranolol. These results suggest that that post-reactivation propranolol recapitulates its effects on consolidation, this time by blocking reconsolidation of the traumatic memory. Several important questions remain unanswered. First, does propranolol also weaken traumatic memories in combat-related PTSD? Second, does this weakening effect only occur when the propranolol is given after combat memory reactivation? If not, this would refute the reconsolidation hypothesis and suggest that propranolol affects non-specific mechanisms. Third, how long does the traumatic memory weakening last? The proposed project will investigate these questions by performing an improved, double-blind, placebo-controlled study in Iraq and Afghanistan veterans with combat-related PTSD. Participants will be randomly assigned to one of two groups: post-reactivation propranolol or non-reactivation propranolol. Participants in the non-reactivation propranolol group will receive propranolol in the absence of traumatic memory reactivation. Participants randomized to the post-reactivation propranolol group will receive matching placebo capsules. Two days later, all participants will return for a script preparation session, at which time they will describe the details of their traumatic event. Participants randomized to the post-reactivation propranolol group will then receive propranolol, whereas participants randomized to the non-reactivation propranolol group will receive placebo. Participants will then return for psychophysiologic script-driven imagery testing one week and six months later. We hypothesize that those who receive propranolol after reactivation of their memories of their traumatic combat event(s) will show significantly smaller psychophysiologic responses during script-driven imagery testing compared to participants who receive propranolol in the absence of combat memory reactivation, supporting the inference that post-reactivation propranolol blocks the reconsolidation of traumatic combat memories.
The goals of the proposed research are to produce preliminary evidence of PE with OEF/OIF veterans with PTSD and to examine cognitive, psychophysiological, and neuroendocrine mechanisms of change in PTSD treatment. In brief, 36 OEF/OIF veterans with chronic PTSD or PTSS of at least 3 months duration will be randomly assigned to 15 sessions of either PE or TAU (see below for descriptions of the interventions). All veterans will receive psychobiological assessments at pre treatment, mid treatment, post treatment, 3 months, and 6 months follow-up. Each of these assessments will cover in 2 sessions on separate days and will include interview and self-report of symptoms (i.e., PTSD, depression, and general anxiety severity), self-report of PTSD-related cognitions, psychophysiological (i.e., heart rate, skin conductance, respiration, and end-tidal CO2) assessment during neutral and trauma scripts, and assessment of salivary cortisol during neutral and trauma scripts. Also, on the morning prior to each laboratory assessment, patients will collect salivary cortisol at the moment of waking and 30 and 45 minutes post-walking. In addition to these assessments, patients assigned to PE will collect salivary cortisol during three imaginal exposure sessions (sessions 3, 9, and 15).
The investigators are studying whether a brief three-session mind-body workshop helps people with fibromyalgia. The investigators hypothesize that this workshop will significantly improve pain and other symptoms, compared to usual care.
This study will assess the effectiveness of taking propranolol soon after a traumatizing incident in reducing the incidence and severity of posttraumatic stress disorder in acutely traumatized individuals.
This 10-week study will examine whether propranolol, a medication that blocks the activity of the stress hormones adrenaline and noradrenaline, can relieve acute stress disorder (ASD) and symptoms from persisting long-term. ASD is a condition that some people develop soon after exposure to trauma. They may be anxious, depressed, have trouble sleeping, startle easily, have difficulties concentrating, and feel as though the event is happening again. Propranolol has been used for many years to treat high blood pressure and heart disease, and has been found useful in treating anxiety states such as social phobia and migraine. Men and women between 18 and 65 years of age who were recently exposed to trauma (between 1 and 3 weeks of evaluation in this study) may be eligible for this study. Candidates must be diagnosed with ASD and must have been mentally healthy before the traumatic event. They will be screened for the study with a medical and psychiatric interview, physical examination, electrocardiogram (EKG), and blood and urine tests. Participants will be evaluated with the following procedures: * Neuropsychological tests using pen-and-paper and computer tests to evaluate cognitive function, particularly memory, learning, attention and concentration, and vocabulary and naming. * Emotion-related performance tasks to determine if the study medication can weaken emotionally arousing information by blocking the activity of adrenaline and noradrenaline. Subjects perform emotion-related and neutral tasks, such as looking at pictures with neutral, pleasant, or unpleasant content, both before and after treatment with the study medication (see below). * Traumatic script exposure: Subjects recount the traumatic event that caused them to develop ASD. The description is summarized, recorded, and played back to the subject. During the playback, physiological responses, such as heart rate and skin conductance (sweating), are recorded using electrodes taped to the hand and chest. * Fear conditioning to evaluate the response to an unpleasant stimulus: Several mild electrical shocks are delivered to the wrists while the subject looks at colored squares. Heart rate and skin conductance are measured. * Magnetic resonance imaging (MRI) to examine brain structure. The subject lies on a table that is moved into the MRI scanner (a narrow cylinder containing a strong magnetic field) and must remain still during the actual scanning. Earplugs are worn to muffle loud noises caused by electrical switching of radio frequency circuits used in the scanning process. After the evaluation, participants are randomly assigned to receive either propranolol or placebo (a look-alike pill with no active ingredient) for 8 weeks During this time they are seen by a doctor once a week for 4 weeks and then once every other week for the rest of the study. At the end of the 8-week treatment period, participants undergo the same evaluation they had before beginning treatment (see above). The decision to continue treatment will then be decided based on the individual's clinical condition and whether he or she received propranolol or placebo.
Fear and anxiety are normal responses to a threat. However, anxiety is considered abnormal when the response to the threat is excessive or inappropriate. This study will examine changes in the body and brain that occur during unpleasant learning experiences in healthy volunteers with high, moderate, and low levels of anxiety. A high degree of generalized anxiety is a component of many anxiety disorders and is regarded as a marker of vulnerability for these disorders. People with anxiety disorders and individuals with high degrees of anxiety have inappropriate expectations of unpleasant events. This study will investigate the development of expecting unpleasant events in healthy volunteers with varying degrees of anxiety using aversive conditioning models. A later phase of the study will enroll participants with anxiety disorders and compare their responses to those of healthy volunteers. Patients who meet criteria for an anxiety disorder, and healthy volunteers who have no history of psychiatric or major medical illness will be enrolled in this study. Volunteers will come to the NIH Clinical Center three times for outpatient testing....
The purpose of this study is to examine the short-term consequences of trauma and to determine the effectiveness of the drug sertraline in preventing and treating post-traumatic stress disorder (PTSD) and acute stress disorder (ASD) symptoms. ASD and PTSD are common consequences of exposure to traumatic events. Despite growing evidence of neurobiological dysfunction in ASD and PTSD, the origin of these disorders is still unknown. This study will attempt to identify psychophysiological markers of ASD and find an effective treatment for its symptoms. Victims of serious motor vehicle collisions will be evaluated with clinical assessments and standardized questionnaires within 2 weeks after the accident. Symptoms of exaggerated startle, emotional reactivity to trauma-related and trauma-unrelated cues, and cerebellum functioning will be evaluated. Participants will be randomized to receive either sertraline or placebo (an inactive sugar pill) for 8 weeks. Psychometric testing and psychological evaluations will be conducted 4, 10, and 14 weeks after the accident and after a 2-week taper of the study medication.
The purpose of this study is to determine the safety and effectiveness of clozapine in children and adolescents with treatment resistant bipolar disorder. This study will also explore how the brain functions in early-onset bipolar disorder.
Subjects with chronic migraine or tension headaches will receive 12 sessions of biofeedback or relaxation training after fulfilling screening, intake interviews, \& psychological testing requirements. They will chart headache pain, anger level, \& medication usage throughout baseline, treatment, and 3 month follow-up periods. Migraine sufferers will receive a combination of progressive muscle relaxation training and thermal biofeedback (learning to warm hands). Subjects are randomly assigned to receive treatment either in the office with the therapist or from another room (where communication will be over a computer). The research is designed to compare the effectiveness of treatment based on location. Tension headache sufferers will receive training in how to reduce their muscle tension levels. They will be randomly assigned to have equipment monitor muscle tension levels either in the forehead or shoulder regions. The research is designed to compare the effectiveness of feedback to the forehead versus the shoulder muscles.
