Filter by:The present study seeks to evaluate the clinical utility of repeated transcranial alternating current stimulation (tACS) by assessing long-term, lasting changes in oscillatory activity and subsequent changes in related behavioral processes of anxious arousal and sensory sensitivity. To date, only transient effects of tACS have been reported, lasting no longer than 30 to 70 minutes. In order to be truly impactful within a clinical setting, however, evidence for long-term effects of tACS is needed.
Neurofibromatosis type 1 (NF1) is one of the most common autosomal dominant genetic disorders. The aim of our study was to evaluate post-traumatic stress disorder (PTSD) in patients and their families following the disclosure of sporadic NF1. Diagnosis of NF1 was retained according to NIH criteria, familial forms were excluded. The French version of the Impact of Event Scale-Revised was used for the diagnosis of PTSD.
Post-traumatic stress disorder (PTSD) is a psychiatric pathology noticed in the DSM-5, in troubles due to a traumatism or a stress factor and appearing at least 1 month after confrontation with trauma. This trouble can become chronic, and be the source of psychiatric and somatic comorbidities, which themselves have personal, professional and economic consequences at the level of the individual and society. Some studies looked at the psychological effects induced by a stay in intensive care unit (ICU) since few years. The emergence of PTSD in these patients has been described, with an incidence varying from 4% to 60%. The literature is contradictory about identified risk factors for PTSD. It's not possible to design a screening of these patients actually, only focused on the risk factors. It has been shown that the presence of acute stress trouble (presence of symptoms during the first month after the traumatism) was a risk factor for PTSD. Early detection of acute stress disorder could be a way to screen risk of emergence of a post-intensive care PTSD. Post-intensive care consultations have been done at 6 months, but not systematically. Only few symptoms are looked for and a sizable part of this population were not being followed probably due to a non-diagnosed-PTSD. In case of the emergence of a post-intensive care PTSD, those patients will never be diagnosed and treated, favoring all complications linked to this trouble. Associated with other factors, IES-R (Impact Event Scale Revisited) at the ICU exit would permit an exhaustive screening of patients at risk for PTSD and could permit to propose them an adapted care and then limit the emergence of PTSD and its consequences.. In this study, the investigators will screen acute stress symptoms within 8 days following the ICU's exit, using the IES-R, in order to evaluate his ability to predict the emergence of a PTSD at three months. IES-R is an auto-questionnaire, easy and fast with good psychometrics capacities for PTSD.
This project aims to determine whether cannabidiol (CBD), a compound derived from the cannabis plant, is effective in treating alcohol use disorder (AUD) in individuals with comorbid posttraumatic stress disorder (PTSD). Investigators will test the hypothesis that oral cannabidiol (CBD) will reduce alcohol drinking in individuals with AUD comorbid with PTSD. To test this hypothesis, 48 otherwise healthy adult participants with moderate or severe AUD and PTSD will be randomized to treatment with either CBD (600 mg daily) or placebo, for a period of 6 weeks, such that both participants and study staff are blind to treatment condition. Participants (each treated for 6 weeks) will be continuously recruited over a study period of 14 months until 48 have completed. Baseline and weekly data will be collected on alcohol usage and PTSD symptoms, and investigators will assess whether CBD treatment leads to a greater improvement in these measures relative to placebo, and whether reduction in alcohol drinking is temporally linked to improvement in PTSD symptoms. Subjects will also participate in a task designed to quantify the psychological and physiological links between negative emotion produced by re-experiencing PTSD trauma, and alcohol craving. The task will be administered following 4 weeks of treatment. Treatment-associated reduction in alcohol craving elicited by trauma-associated negative emotion between CBD and placebo groups will be compared. This study will be the first to test whether CBD is effective in treating alcohol addiction and in treating PTSD in humans, and the first to examine the interaction between these treatment effects. Results will serve as proof of concept and provide guidance for a future larger clinical trial. Because CBD is a safe, readily available drug, such a trial would have an immense potential to prevent death, medical illness, and psychological suffering associated with AUD and PTSD. Further, because the brain circuits via which CBD acts to produce hypothesized effects are relatively well-understood, results may substantially advance understanding of the neurobiological basis of alcohol addiction.
The purpose of this study is to quantify the therapeutic efficacy and role of trained service dogs on socio-emotional functioning among military veterans with posttraumatic stress disorder (PTSD).
mTBI is a leading cause of sustained physical, cognitive, emotional, and behavioral deficits in OEF/OIF/OND Veterans and the general public. However, the underlying pathophysiology is not completely understood, and there are few effective treatments for post-concussive symptoms (PCS). In addition, there are substantial overlaps between PCS and PTSD symptoms in mTBI. IASIS is among a class of passive neurofeedback treatments that combine low-intensity pulses for transcranial electrical stimulation (LIP-tES) with EEG monitoring. Nexalin is another tES technique , with FDA approvals for treating insomnia, depression, and anxiety. LIP-tES techniques have shown promising results in alleviating PCS individuals with TBI. However, the neural mechanisms underlying the effects of LIP-tES treatment in TBI are unknown, owing to the dearth of neuroimaging investigations of this therapeutic intervention. Conventional neuroimaging techniques such as MRI and CT have limited sensitivity in detecting physiological abnormalities caused by mTBI, or in assessing the efficacy of mTBI treatments. In acute and chronic phases, CT and MRI are typically negative even in mTBI patients with persistent PCS. In contrast, evidence is mounting in support of resting-state magnetoencephalography (rs-MEG) slow-wave source imaging (delta-band, 1-4 Hz) as a marker for neuronal abnormalities in mTBI. The primary goal of the present application is to use rs-MEG to identify the neural underpinnings of behavioral changes associated with IASIS treatment in Veterans with mTBI. Using a double-blind placebo controlled design, the investigators will study changes in abnormal MEG slow-waves before and after IASIS treatment (relative to a 'sham' treatment group) in Veterans with mTBI. For a subset of participants who may have remaining TBI symptoms at the end of all IASIS treatment sessions, MEG slow-wave changes will be recorded before and after additional Nexalin treatment. In addition, the investigators will examine treatment-related changes in PCS, PTSD symptoms, neuropsychological test performances, and their association with changes in MEG slow-waves. The investigators for the first time will address a fundamental question about the mechanism of slow-waves in brain injury, namely whether slow-wave generation in wakefulness is merely a negative consequence of neuronal injury or if it is a signature of ongoing neuronal rearrangement and healing that occurs at the site of the injury.
The BASIC study will take place in Kanduyi/Bungoma South Sub-County, in western Kenya, and focuses on children orphaned by one or two parents. Growing evidence demonstrates that orphaned children in low- and middle-income countries are at higher risk of mental health problems, but mental health professionals are largely unavailable in this area. Research suggests that some mental health treatments can be delivered effectively in low- and middle-income countries using a task-shifting approach, in which lay counselors with little or no prior mental health experience are trained to provide treatment, and deliver with supervision. However, very little is known about how to support local systems and organizations in delivering mental health care via task-shifting, particularly in a way that could scale-able and sustainable in the low-resource context. The BASIC team's prior work suggests that partnering with two government sectors, education and health, could be a low-cost and sustainable strategy to implement task-shifted mental health services. By training teachers (via the Education sector) and community health volunteers (via the Health sector) to provide mental health care, a larger population could potentially be reached. Before attempting any country or system-wide implementation, it is important to know what is needed to enable successful implementation in either or both sectors, client outcomes for those receiving mental health care when delivered via Education or Health, and cost of delivery in both sectors. The team aims to collect outcomes that are relevant to policy makers, and that can be considered along with cost and experiences in both sectors.
This pilot study investigated the trauma reducing effects of the Transcendental Meditation program on female prisoners The study was conducted over the 4 month period and measured total trauma symptoms at baseline and posttest in both the TM experimental group and waitlist controls
This study will evaluate the effects of Mindfulness-Based Stress Reduction (MBSR) on physiological reactivity. This study will focus on individuals with anxiety who will participate in an 8-week MBSR class. The investigators will test participants' reactivity to both predictable and unpredictable stimuli before and after the class to understand the physiological changes that may occur after to the intervention. Secondary measures include psychometric instruments and a delay discounting task.
The primary objective of this study is to evaluate the feasibility of the revised brain training program with individuals diagnosed with Alcohol Use Disorder (AUD) and Post-Traumatic Stress Disorder (PTSD).
