Filter by:A broad group of disorders is associated with severe stress existence in children or adolescents. The most characteristic result, and one of the most serious being the state of post-traumatic stress disorder (PTSD), whose main source consists of physical or sexual violence, and to a lesser extent, accidents public road or natural disaster, whose child was the subject or witness. PTSD is associated with a deleterious effect on cognition and including the mnemonic operation. The painful reminder of the traumatic event is one of the most disabling symptoms. However, there are many other memory disorders that experimental studies gradually update. They maintain a close link with emotional regulation that disturbed you know if PTSD. However the majority of studies on emotion and cognition and their relationship with brain activity took adult subject. Work in adolescents are few on the morphological study, on rare neurobehavioral and reduced to two studies of functional neuroimaging. Contrary to what is observed in adults, morphological studies report consistently, no reduction in hippocampal volume. There is no study in the idle state. Two studies in functional MRI, the first highlighted in PTSD patients inhibition of the activity of the anterior cingulate cortex (ACC) to stimuli such as to evoke the trauma, a second reported increased activity in the prefrontal cortex Median (mPFC) in a inhibition. The objective task of our study is to evaluate the impact of psychological trauma on brain structures involved in the emotional component of the memory (amygdala, hippocampus, prefrontal cortex in particular). For this, the investigators will take in 33 adolescents, including patients with posttraumatic symptomatology and matched controls free of trauma age, several neuroimaging exams, anatomical and functional. The functional review will include some rest and another in activation during episodic memory task designed to assess the influence of self-perception on memory impairment observed in patients. The investigators will check, for each group of patients and controls, the involvement of cortical structures in relation to the regulation of emotional memory (CCA, amygdala and hippocampus). The anatomy of the hippocampus benefit specific imaging methods developed in the unit INSERM U923. Endocrine correlates of stress tests will be studied by a fully-traumatic by salivary cortisol sampling. This research will clarify the mechanisms involved in emotional and memory impairments secondary to psychological trauma, their relationship with self (judgment and self-esteem) and studying their morphological substrates. A longer-term goal is to offer help in the diagnosis and monitoring of young patients with posttraumatic symptomatology.
Individuals with affective disorders (including post-traumatic stress disorder (PTSD) and major depressive disorder (MDD)) often experience declines in cognitive abilities such as memory and attention. Such difficulties can reduce functioning in important aspects of life, including at work or school. Little research has been conducted to investigate if cognitive dysfunction can be reduced in individuals with PTSD or MDD following a specific treatment. Thus, the investigators plan to determine the utility of a cognitive training program called goal management training (GMT) in reducing cognitive dysfunction in MDD/PTSD. GMT aims to assist participants in building skills in performing specific behaviours that rely on basic cognitive processes, allowing them to achieve an identified goal. 64 individuals with PTSD and 64 with MDD will be divided into two groups of 32, one GMT group, and one wait-list group that will receive GMT after study completion. The investigators predict that in comparison to the wait-list group, the GMT group will show greater improvements in cognitive functioning and everyday functioning following treatment and that these improvements will remain long-term.
This pilot study aims to investigate the effects of a brief computerized intervention (the computer game "Tetris") on intrusive memories and other posttraumatic stress symptoms following an emergency cesarean section. Patients who have undergone an emergency cesarian section will be randomly allocated to either the brief computerized intervention or usual care within the first 6 hours following the operation. Participants will be followed up at one week and one month. It is predicted that participants given the brief computerized intervention will develop fewer intrusive memories and less severe clinical symptoms than those who are not. This will inform the potential future development of a simple computerized intervention to prevent distressing psychological symptoms after a traumatic event such as an emergency cesarean section.
The purpose of the current study is to develop a better understanding of the brain mechanisms involved in psychological treatments for posttraumatic stress disorder (PTSD). This project will build on past research using script-driven imagery in our lab by investigating brain activity in areas activated during exposure to trauma-related cues. This project will also develop new knowledge concerning volitional control of those areas. The ultimate goal of this study is a better understanding of whether volitional control of these brain areas will improve therapeutic outcomes. This process will first be piloted in a sample of healthy controls. This will allow investigators to refine the methodology prior to recruiting a sample with PTSD.
The proposed study will examine the efficacy of doxazosin in the treatment of PTSD and alcohol use disorder or substance use disorders.
The proposed pilot study is designed to test the feasibility, acceptability, and potential effectiveness of a mobile phone application (app) developed by the VA National Center for PTSD (VA NCPTSD) for use by family members of those with Posttraumatic Stress Disorder (PTSD). The primary objective of the proposed study is to assess whether family members of veterans with PTSD find the PTSD Family Coach app to be satisfactory and feasible to use. Secondary objectives are to determine if use of the app increases family members' self-efficacy and their ability to manage their own life stress, which may in part be the result of living with someone who has PTSD.
The purpose of the present study is to evaluate the safety and efficacy of Brainsway Deep TMS (DTMS) for the treatment of PTSD.
Anxiety disorders are common disorders, which pose a major burden to society and the individual. An anxiety disorder may be treated with medication, in particular with antidepressants such as the selective serotonin reuptake inhibitors (SSRIs). However, much of what is known about antidepressants is derived from research in depression rather than anxiety. In recent years, researchers have found that antidepressants are more effective for severely depressed patients than they are for patients with milder symptoms. It is possible that a similar relationship between symptom severity and antidepressant efficacy exists for anxiety disorders, but there is currently little evidence available to answer this question. As antidepressants are frequently prescribed to patients with mild or moderate anxiety, a clear understanding of their effectiveness across the severity range is vital to inform treatment decisions. Therefore, the purpose of this meta-analysis is to examine whether initial symptom severity affects antidepressant efficacy for anxiety disorders.
This study will investigate the effects of oxytocin on alcohol-related behaviors, social abilities, and physiological startle responses in healthy individuals and patients with posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) using a randomized, placebo-controlled, dose-tiered, between-subject study design. Specifically, the investigators will determine if intranasal administration of a single dose of the pro-social neuropeptide oxytocin decreases alcohol-related approach bias and cravings, enhances social abilities, and decreases physiological hyperactivity. The investigators will also determine the optimal dose to achieve these effects and will explore psychosocial predictors of responses to oxytocin. The proposed work has the potential to yield a novel pharmacological treatment for AUD and PTSD, both leading causes of disability in the US Military for which currently available treatments are inadequate.
The purpose of the study is to determine whether a novel integrated cognitive-behavioral treatment for posttraumatic stress disorder (PTSD) and substance dependence (i.e., Treatment for Integrated Posttraumatic Stress and Substance use; TIPSS) is more effective than cognitive-behavioral treatment for substance dependence alone with regard to PTSD symptoms and substance use quantity and frequency.
