Cortisol Suppression and Startle Responses in Posttraumatic Stress Disorder (PTSD)
Post Traumatic Stress DisorderPosttraumatic stress disorder (PTSD) occurs in some people after exposure to events that cause extreme fear or helplessness. The incidence of war zones worldwide and the prevalence of violence in large cities in the U.S., increases the likelihood that people will experience a traumatizing event in their lifetime. About 1 in 10 people who survive such events will develop PTSD, while most people will get better over time. This suggests that some people may have biological vulnerabilities that make it harder for them to recover. One of these biological risk factors may be related to how stress hormones work in people who get sick. Another is how people react to things that make them afraid or nervous, investigators have found that PTSD patients have higher than normal fear reactions. The part of the brain that reacts to fearful stimulation is linked to stress hormones; the purpose of this study is to examine how these systems interact. The study will suppress stress hormones (cortisol) production in one group of participants, while another will get a placebo. When their cortisol is suppressed, the participants will undergo a startle study to see if their fear responses are decreased. Investigators expect that people PTSD will show a normal fear response when their cortisol levels are reduced, similar to people without PTSD. This research can help discover new medicines for people with PTSD.
Self-Efficacy Enhancing Interviewing Techniques Study
DiabetesDepression3 morePatient self-efficacy, or confidence in one's ability to take the necessary steps to achieve a goal, has been shown to influence a number of important health behaviors and outcomes. However, current ways of increasing patient self-efficacy are time and labor intensive and occur away from doctor visits, where most health care is delivered. We developed, and are testing in a study the effectiveness of a new way of teaching doctors how to talk to patients during office visits in a way that will boost their patients' self-efficacy for changing important health behaviors.
Telephone-based Care for OEF/OIF Veterans With PTSD
Post-Traumatic Stress DisorderObjective: OEF/OIF (Operation Enduring Freedom and Operation Iraqi Freedom) veterans are presenting with high rates of PTSD. Translating Initiatives for Depression into Effective Solutions (TIDES) is a model of phone-based care being implemented nationally as a model to address those patients suffering from depression, PTSD, or alcohol use disorders. However, evidence-based treatments do not yet exist for phone-based management of OEF/OIF veterans who suffer from PTSD. Research Plan: This is an open trial to assess feasibility of augmenting standard treatment of PTSD with TIDES based telephone-based nurse care management.
Stress Reactivity in Veterans Receiving Pharmacological Treatment for PTSD and Alcohol Dependence...
Post-traumatic Stress DisorderAlcohol DependenceMethod: 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.
Evaluating a Telehealth Treatment for Veterans With Hepatitis C and PTSD
Chronic DiseaseHepatitis C2 moreThe main objective of this proposal is to develop and test the efficacy of two interventions (a telehealth and face-to-face intervention) designed to improve quality of life, self-care, motivation to engage in healthcare, and psychological distress in patients diagnosed with HCV and PTSD. It is hypothesized that
Psychological Symptoms and Families of COVID-19 Patients
Family MembersPost Intensive Care Unit Syndrome1 moreFamilies of patients in Intensive Care Units (ICUs) are at increased risk for developing psychological symptoms that can last for months after the patient is discharged. These symptoms can have significant impact on both the patient and family member's quality of life. The investigators have found that families of patients admitted to the Rush University Medical Center ICU during to the COVID-19 pandemic were more likely to develop clinically significant psychological symptoms than families of patients admitted prior to the COVID-19 pandemic. The investigators suspect that this finding is due in part to the hospital-wide no visitation policy that altered our standard communication practices and may have prevented families from being active participants in the patient's medical care. The goals of this project are 1) to determine the prevalence of psychological disorders among families of COVID-19 patients after ICU discharge 2) to determine the characteristics of ICU care that were associated with the development of psychological disorders among family members and 3) to pilot a program in which families with psychological disorders after ICU discharge receive therapy from mental health professionals.
Early EMDR Following Covid-19 Critical Illness: A Feasibility Trial
Post Traumatic Stress DisorderIntensive Care Psychiatric Disorder4 morePrimary objective is to evaluate the feasibility of delivering an online early Eye Movement Desensitisation Reprocessing (EMDR) Recent Traumatic Events Protocol (R-TEP) to patients who have survived Covid-19 related critical illness, within the context of a randomised controlled trial (RCT). This will inform the design of a future RCT investigating the effectiveness of EMDR R-TEP in reducing psychological symptoms, for adult survivors of intensive care.
PTSD Affect Labeling Study
Post-traumatic Stress DisorderPost-Traumatic Stress Disorder1 moreThe overall goal of this study is to use fMRI and psychophysiological measures to investigate a novel strategy involving "Affect Labeling" for improving emotion regulation in PTSD that could lead to a new treatment regimen for PTSD. Our project has two specific aims. First, the investigators aim to identify a novel neural target for possible PTSD intervention by verifying that RVLPFC-based inhibitory processing is impaired in PTSD. Second, the investigators will examine whether repeated practice with a simple cognitive-emotional task that requires inhibitory processing, namely, affect labeling, can strengthen the RVLPFC's ability to down-regulate emotional responses and physiological reactivity in PTSD and thereby form the basis of a novel treatment strategy to be developed in future studies. Secondary objectives are to examine the extent to which RVLPFC-based inhibitory impairments in PTSD are specific to trauma-relevant emotional processing (i.e., trauma-related distress) or extend to other types of inhibitory regulation in general, which would have implications for the future study of inhibitory-enhancement-based interventions for PTSD.
PTSD (PostTraumatic Stress Disorder) Services for Veterans With SMI (Severe Mental Illness)
Post Traumatic Stress DisorderSchizophrenia3 moreAs in the general population, there is no clear standard of care within Veterans Affairs Medical Centers for treating posttraumatic stress disorder (PTSD) among individuals with severe mental illness (SMI). This is a considerable issue because trauma, posttraumatic stress disorder (PTSD), and severe psychiatric comorbidity are particularly common among Veterans and this symptom presentation clearly exacerbates the overall course and severity of mental illness. This study is significant in that it proposes to establish the efficacy of a frontline exposure based intervention for posttraumatic stress disorder (PTSD), Prolonged Exposure, for improving critical clinical, quality of life, and cost outcomes among Veterans with severe mental illness (SMI) enrolled in VA healthcare. Collectively, it is anticipated that these data will establish a much needed clinical course of action for what is considered a vulnerable yet highly underserved patient population.
