Filter by:BACKGROUND It is demonstrated that strong associations between trauma suffered in childhood and having schizophrenia, and more specifically to experience acoustic-verbal hallucinations (AVH). A second generation of research is currently examining the cognitive and affective processes likely to play a mediating role in this association. These mediators appear to include early maladaptive personality patterns and dissociative experiences. Although these factors have most often been explored separately, recent research indicates that they could be associated, and thus contribute to AVH. More specifically, another study has shown that the association between childhood trauma and predisposition to AVH is not direct but depends on cognitive factors including the impact of violence suffered during childhood on early maladaptive schemas and dissociation. However, this study was carried out on a non-clinical sample of subjects with a predisposition to AVH. OBJECTIVES: testing a structural model of AVH, childhood trauma, early maladaptive schemas and dissociative symptoms in large multicentric sample of inpatients diagnosed with schizophrenia and AVH (n=350). Secondary objectives are (i) test in the model the role of all the early patterns described by Jeffrey Young instead of targeting only the schemes that are part of the model tested in previous study as the one by Bortolon and colleagues, (ii) compare the quality of the adjustment of the confirmatory model to the quality of the adjustment of the exploratory model. METHODS: one single visit in which subjects will receive self-reported questionnaires (Childhood trauma questionnaire, The Young schema questionnaire short form, Dissociative experiences scale, Launay-Slade hallucination scale and Cardiff Anomalous Perceptions Scale. ANALYSES: Structural equation model performed additional analysis using Partial Least Squares Structural Equation Modelling. The primary endpoint corresponds to significant associations between the variables. The quality of the model will be assessed using a fit quality measure. The secondary endpoints are significant associations between the different variables (p <0.05) and the model quality assessed with a quality measure of the fit. MAIN HYPOTHESIS: the association between childhood trauma and predisposition to AVH is not direct, but depends on the impact of violence suffered during childhood on early maladaptive schemas and dissociative symptoms in patients with schizophrenia.
The study wishes to examine whether "extended" antipsychotic treatment, in this case, antipsychotic treatment every other day, is as effective as daily treatment. It is also evaluating whether there may be differences in terms of side effects. Participants will be randomly assigned to either the treatment as usual group (i.e., taking antipsychotic daily) or the extended dosing group (i.e., taking antipsychotic one day on, one day off). That means, like flipping a coin, there is a 50/50 chance that participants will continue on daily dosing of your antipsychotic or have it switched to every other day dosing. This study will last for 1 year. Participants will be evaluated at the beginning and every two weeks during the first 6 months, with visits once every 4 weeks for the final 6 months. In total, participants will make 22 visits over 52 weeks to the investigator's office. The investigators hypothesize that with ED, there will be no change in symptom severity but improvement in the frequency and severity of side effects, wellbeing, and functioning.
Based on the hypothesis that low-frequency deep transcranial magnetic stimulation(dTMS) on anterior cingulate cortex （ACC） could down-regulate the glutamate level of ACC and regulate the acc-related functional network in patients with treatment resistance schizophrenia,this research plan to utilise multimodal functional magnetic imaging method(including structural MRI,resting-state functional magnetic resonance imaging and 1H-MRS) to investigate therapeutic efficacy of low-frequency deep transcranial magnetic stimulation on SZ patients symptoms,as well as to elucidate the correlation between treatment effects and glutamate level of ACC
Smokers with schizophrenia spectrum disorders have high rates of morbidity and mortality from smoking-related diseases compared with the general population and current options for smoking cessation in this vulnerable group are unsatisfactory. Considering that most people with schizophrenia spectrum disorders continue smoking, it is urgent to consider alternative and more efficient interventions to reduce or prevent their morbidity and mortality. Switching to combustion-free technologies for nicotine delivery (I.e. e-cigarettes) could be a pragmatic and much less harmful alternative to tobacco smoking with the possibility of significant health gains. Emerging research is suggesting that ECs may be useful for smoking cessation and relapse prevention in people with schizophrenia spectrum disorders. In particular, a study conducted with JUUL e-cigarette with 5% nicotine strength showed that this product had sufficient nicotine delivery and product appeal to determine high success rates in heavy smokers with schizophrenia spectrum disorders. In consideration of these preliminary findings, we hypothesized that switching smokers with a schizophrenia spectrum disorder diagnosis to JUUL e-cigarette with 5% nicotine strength could result in higher success rates compared to JUUL e-cigarette with 1.7% nicotine strength. Recent work indicates that nicotine PK of the JUUL e-cigarette with 5% nicotine strength (a device that utilizes a nicotine salt formulation) approximates the nicotine delivery of combustible cigarettes and that the 5% nicotine strength product is far more efficient in delivering nicotine compared to the sister product with 1.7% nicotine strength. Both products are identical in their appearance, making them suitable for a double-blind study design.
The body esteem influences the physical appearance, which can be a social brake. To enhance the socio-professional insertion of persons with severe mental disorders, the investigators developed a group program about self-presentation and body esteem. The study's objective is to understand the body esteem impact on socio-professional insertion, and how to improve that with a dedicated group program, for patients in a psychosocial rehabilitation center
As an ancient, popular Chinese exercise, Baduanjin is characterized by symmetrical posture, deep breathing and meditation and easy to learn. Previous studies showed immediate effect of Baduanjin on cognition in patients with schizophrenia.The purpose of this study is to investigate the immediate effect and chronic effect of Baduanjin exercise on physical fitness, cognition and daily functions in middle-aged and older adults with schizophrenia.
These studies look to conduct efficient pilot testing of a novel intervention strategy for chronic psychotic disorders - Pharmacologic Augmentation of Cognitive Therapy (PACT) - via an experimental medicine approach. Antipsychotics are the major therapeutic tool for chronic psychotic disorders, including schizophrenia, but do not significantly alter their course or real-life impact. Specific cognitive therapies achieve modest symptom reduction and improved function and cognition in psychosis patients, including "bottom-up" sensory-based targeted cognitive training (TCT). While benefits of TCT are evident at the group level, almost half of all patients demonstrate little or no cognitive gains after 30-40 hours (h) of TCT. For patients and clinicians, the costs and logistical complexities associated with these time- and resource-intensive interventions can be prohibitive. We propose and will test a novel "augmentation strategy" for using medications to specifically enhance the benefits of TCT in schizophrenia.
The current study examines the efficacy of a cognitive training intervention for improving emotion regulation in psychotic disorders. it is hypothesized that the cognitive training program will enhance prefrontal activation, leading to enhanced emotion regulation.
Sound and Vision: A collaboration between service-users, artists and the public to explore the lived experience of hallucinations
Veterans with mental illness face challenges with community reintegration, including achieving vocational success, attaining their educational goals and going back to school, and maintaining a high quality of life. VA Mental Health Residential Rehabilitation Treatment Programs, Psychosocial Rehabilitation and Recovery Centers and other mental health treatment programs are designed to help Veterans overcome these barriers, but cognitive impairment often seen in Veterans with mental illness limits gains from these settings. Cognitive remediation interventions can be helpful, but they are either "one-size fits all," and thus may not be useful for all Veterans with mental illness, or are too narrow in scope, focusing on specific mental illnesses, limiting generalizability. This project will test whether an objective neurophysiological biomarker, mismatch negativity (MMN), can better match the "right" Veteran to the "right" cognitive remediation treatment regardless of their specific mental health diagnosis.
