Active clinical trials for "Stress Disorders, Traumatic"

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.

The purpose of this study is to compare two treatments for post-traumatic stress disorder (PTSD): fluoxetine (an antidepressant) and Eye Movement Desensitization and Reprocessing (EMDR, a psychological treatment in which the patient is led through the memory of a traumatic experience in order to heal him/herself). There are a variety of therapies used to treat PTSD, but the effectiveness of medication alone vs an exposure treatment, such as EMDR, has not been tested. Patients will be assigned randomly (like tossing a coin) to one of three groups for 8 weeks of treatment. Group 1 will receive fluoxetine; Group 2 will receive EMDR; and Group 3 will receive inactive placebo. Patients will then stop treatment and have evaluations, including psychological tests, at the time treatment is stopped, 8 weeks later, and at 6 months. An individual may be eligible for this study if he/she: Has PTSD and is 18 to 65 years old.

This study investigates the utility of Goal Management Training (GMT) in patients with post-traumatic stress disorder (PTSD), in order to determine if this treatment is effective in improving cognitive function in patients with frontal-temporally mediated brain dysfunction. Specifically, the primary aim of this study is to examine whether a standardized 9-week program of GMT results in durable improvements in cognitive functioning relative to a wait-list control group. A secondary aim will be to determine whether participation in the GMT group is associated with long-term functional improvements. It is hypothesized that at post-treatment, participants with PTSD assigned to the GMT groups will show greater improvement in neuropsychological test performance and greater functional improvement compared to those in the wait-list group; these gains are expected to be maintained at 3 month follow-up.

This is a small, open-label treatment study that tests the potential safety and treatment effectiveness of a stellate ganglion block combined with Massed Prolonged Exposure (PE). Each of the 12 participants will receive ten 90-minute sessions of Massed Prolonged Exposure and an injection of a stellate ganglion block between the first and second PE sessions.

The standard of care for PTSD involves both psychotherapy and pharmacotherapy, but treatment resistance is common. The discovery of effective complementary treatment approaches would have major implications for patients with PTSD. Mindfulness meditation and related practices have been studied intensively in recent years for a variety of psychiatric illnesses, including depression, generalized anxiety disorder, and PTSD. Studies in PTSD suggest that mindful meditation holds promise. For example, mindfulness-based stress reduction (MBSR) has shown effectiveness for reducing symptom severity and improving mental-health related quality of life in combat-exposed veterans and child survivors of sexual abuse. Mechanistically, mindfulness meditation appears to counteract the types of functional changes that have been identified in the brains of patients with PTSD. In particular, while PTSD symptoms are associated with decreased activation of the prefrontal cortex (PFC) and increased amygdala activity, mindfulness meditation is associated with increased PFC activation and decreased amygdala activation. Other physiological effects of mindfulness meditation in patients with PTSD are not fully defined. However, available data suggest that it leads to a normalization of vagal tone and plasma cortisol levels, which are known to be abnormal in patients with chronic PTSD. Research utilizing validated and standardized pre- and post- PTSD outcome measures, in addition to pre- and post- physiologic variables such a vagal tone, plasma cortisol and catecholamine levels, may better the understandings of physiological effects of mindfulness medication.

This feasibility study investigates the impact of reminder-focused-positive-psychiatry (RFPP) on attention-deficit-hyperactive-disorder (ADHD) and posttraumatic-stress-disorder (PTSD) symptoms, vascular-function, inflammation and well-being of adolescents with comorbid ADHD & PTSD. In this randomized clinical trial, 24 subjects with comorbid ADHD and PTSD, aged 12-18 years old, free of known medical and other major psychiatric disorders, will be recruited from the pool of eligible subjects at Los Angeles and Kern County Children Mental Health Centers (>1500 subjects) after obtaining informed consent from parents as well as subjects' assentment. Commonwealth and Oswell Kern County Mental Health Clinic will be used for subjects enrollment, randomization as well as study implementation from trauma disorder clinic. Kern Medical will be used for manuscript write up and analyses. Adolescents will be randomized to: group-RFPP or trauma-focused group-cognitive-behavioral-therapy (TF-CBT). Participants will complete twice-weekly-intervention for 6-weeks-trial. The group-RFPP-intervention will be inclusive of RFPP interventions on a) traumatic-reminders, and b Avoidance & negative-cognition. Vascular-function-measured as temperature-rebound (TR), C-reactive-protein (CRP), homocysteine, SNAP-questionnaire, Clinician-Administered PTSD-Scale-children-version (CAPS-CA) and neuropsychiatric-measures will be measured at baseline and 6th week. Subjects will be followed for 12 months. Parents and subjects will be informed of the risks associated with use of venipuncture and loss of confidentiality of collected information.

The purpose of this research is 1) to investigate the role of the sympathetic nervous system and cardiac-vascular function in women with PTSD; and 2) to determine whether lifestyle modifications (exercise training and healthy eating) would be effective in reducing sympathetic activity, improving cardiovascular function, and improving psychiatric and quality of life outcomes in women with PTSD. It is hypothesized that (1) women with PTSD will have over-activation of the sympathetic nervous system and impaired cardiac-vascular function compared with women who are trauma free, and (2) lifestyle modifications can reduce sympathetic activity, improve cardiac-vascular function, and improve psychiatric symptoms and quality of life in women with PTSD.

The purpose of the study is to investigate whether an occupational therapy program could enhance mental health outcomes for veterans who SCUBA dive. SCUBA diving requires modified breathing techniques and has been found to provide calming effects to individuals who engage in this activity. Occupational therapy interventions such as mindfulness, journaling, and deep breathing techniques can also provide similar calming effects. Therefore, this study will explore whether occupational therapy can provide additional benefits to overall mental health of veterans who SCUBA dive.

The purpose of this study is to determine if cognitive processing therapy (CPT) delivered in a massed format (MCPT) is as effective as standard delivery of CPT. MCPT will be delivered in an intensive outpatient setting (12 sessions in 5 days) composed of both group and individual sessions. Standard delivery of CPT consists of 12 sessions over 6 weeks and involves only individual sessions. Assessment of PTSD and related symptoms will be conducted at pre-treatment and 1 month and 4 months following treatment in both conditions. Additionally, in order to compare the treatment groups at the same point in actual time, each group will be assessed at the one month posttreatment time point for the other condition.

The purpose of this study is to learn more about Narrative Exposure Therapy for Justice Involved Veterans. This pilot study will examine the feasibility of this intervention in a justice-involved veteran population, and will see whether the intervention needs to be tailored to best meet their needs. The investigators will examine whether the intervention impacts key clinical outcomes, including posttraumatic stress disorder symptoms, as well as on measures of moral injury, anger, depression, suicidality, and aggression.
