Filter by:Introduction: Numerous studies support the practice of different physical exercise modalities as an effective treatment to address the different problems associated with schizophrenia, reporting that they result in significant improvements in patient symptoms and quality of life. Given the lack of studies comparing different types of training in controlled environments, the aim of this proposed study will be to compare the effects of three physical exercise programs (strength, aerobic, and mixed) on the symptoms, body composition, level of physical activity, and health-related quality of life of patients with schizophrenia. Ethics and dissemination: This study was approved by the ethics committees for Biomedical Research at the CEU Cardenal Herrera University of Valencia in Spain (reference number: CEI18/215). Participants will be fully informed of the purpose and procedures of the study, and written informed consent will be obtained from every participant. The results from this study will be published in peer-reviewed journals and presented in scientific conferences.
The INTRUDE trial aims at assessing the efficacy of an fMRI-based neurofeedback procedure on drug-resistant auditory hallucinations. Hallucinations are complex and transient mental states associated with subtle and brain-wide patterns of activity for which we were recently able to validate an fMRI multivariate decoder. Based on this progress, we can track patients' hallucinatory status using real-time fMRI. We will test whether schizophrenia patients with drug-resistant hallucinations can be trained to maintain the brain state associated with a no-hallucination condition using appropriate strategies and thus reduce overall severity. We will refer to a double-blind randomized placebo-controlled design. A total of 86 patients will be enrolled and equally split in an active neurofeedback group (n=43) and a sham group (n=43), matched for sex, age and PANSS scores. Each patient will benefit from 4 runs of either active or sham neurofeedback. The primary outcome measure will be the mean decrease of AHRS scores relative to baseline, and at 1 month post-treatment. We expect significant clinical benefits from fMRI-based neurofeedback on drug-resistant hallucinations compared with the sham group.
In the last years, the imbalance between excitatory and inhibitory neuronal activity has come to the fore as a possible molecular disease mechanism of schizophrenia . Pharmacological studies have suggested different fMRI and EEG markers of that molecular dysfunction (resting state connectivity changes, auditory mismatch and steady state deficits). However, previous research is inconclusive regarding their genetic basis, their reliability, inter-individual relationship as well as disease specificity. Therefore, in this study we aim at estimating the effect sizes, test-retest-reliability and clinical correlates of the respective markers in a comparative fashion in patients with schizophrenia, their relatives and healthy control subject. To assess their molecular validity, we will assess their relationship with glutamatergic and GABAergic genotypes and cellular disease models. The proof of such a relation would give the opportunity of detecting a glutamatergic and GABAergic imbalance throughout non-invasive imaging. Furthermore, it would help deepening our understanding of the molecular pathophysiology of mental disorders which will be essential for the development of more effective drugs.
The diagnostic announcement of a chronic disorder is an essential step in the patient's care. Recommendations specify the importance of including caregivers at the time of the announcement. In practice, caregivers are not systematically associated with the announcement of the diagnosis of schizophrenia, while the daily support of patients is provided in 75% of cases by the family. This support can lead to the exhaustion of caregivers and have repercussions on their sick loved one. This study will qualitatively describe and explore the experience of the diagnostic announcement in relatives of patients with schizophrenia. Specifically, the investigators will explore the history before the diagnosis is announced, the conditions of the announcement and the experiences of relatives as well as the impact at the personal and family-levels. This study will also explore the expectations of caregivers and avenues for reflection for announcement of schizophrenia diagnosis. The number of subjects to be included in this study is therefore set at 30. A preselection of each potential participant will be carried out by phone or in person to ensure the presence of inclusion criteria and the absence of non-inclusion criteria. The patients will also be provided with oral information about the study to allow sufficient time to reflect before inclusion. Then, the selection-inclusion-interview visit will take place visually in an intra-hospital or extra-hospital consultation structure of the Center Hospitalier Alpes-Isère. This visit will be unique and will consist of the entire protocol. It will be both a selection, inclusion and interview visit. Once the results have been analyzed, this study will provide a better understanding of the experiences of relatives of patients when the diagnosis of schizophrenia is announced, the impact of this announcement on caregivers and family relationships and the expectations of caregivers regarding this announcement. In the long term, the data collected will be add value in developing medical recommendations on consultation to announce the diagnosis of schizophrenia to relatives of patients, in order to best meet the expectations of relatives and to minimize as much as possible the harmful impact that can have such announcement.
The aim of this study is to assess the efficacy of a short term compensatory cognitive group intervention - the Compensatory Cognitive Training (CCT) among people with severe mental illnesses, receiving ambulatory treatment
Negative symptoms are one of the five-dimensional symptoms of patients with schizophrenia, and medications are not effective in treating negative symptoms. The mechanism of negative symptoms of schizophrenia is unknown, which may be related to insufficient dopamine function of the prefrontal cortex. Amisulpride is a D2/D3 receptor antagonist, which can improve negative symptoms. Intestinal microbes are related to central nervous system mental diseases. Animal studies have found that changes in the intestinal microflora are related to schizophrenia. Clinical studies have found that the gut microbes of patients with schizophrenia are different from those of normal healthy people. Therefore, we are trying to discover the changes of gut microbes in patients with effective amisulpride treatment, and to improve the negative symptoms of schizophrenia patients through the intestinal immune system. The mechanism of brain relationship provides direction, and also provides a new way for the drug treatment of negative symptoms.
The project intends to take treatment-resistant schizophrenia as the research object and uses sequential multiple assignment randomized trial(SMART) design to define the treatment recommendations of different drug regimen for treatment resistant schizophrenia and to determine the physical enhancement regimen for clozapine-resistant schizophrenia and to explore targeted regulation scheme for ultra-resistant schizophrenia.
Patients with schizophrenia have a higher risk of committing violent crimes than the general population, and the relative risk of violence against others is four times higher than the general population. Violence is a major public health problem because it often leads to poor prognosis, readmission and stigma in patients with schizophrenia. MRI studies on violent behavior in schizophrenia are relatively few. These studies have found that violence is primarily associated with dysfunction in the ventral prefrontal and temporal limbic systems. Structural MRI found that violent behavior in schizophrenia was associated with increased volume of white matter in caudate nucleus, left orbitofrontal gyrus and right orbitofrontal gyrus. However, the current research results in this field are uneven, the methods are not consistent, and there is a lack of breakthrough progress, which needs to be integrated and deepened urgently. If the violent behavior of the patients with schizophrenia could be predicted by magnetic resonance imaging, it would be a revolutionary try. By doing so, the investigators can strengthen the treatment of these patients and reduce the occurrence of violence. Based on previous studies, the investigators believe that violent schizophrenics exhibit recognizable imaging characteristics under structural phase, resting state, negative emotional images and natural stimuli models. Anomalies in a particular mode may be subtle and difficult to identify, but when multiple different modes are integrated, a significant and characteristic set of imaging markers will be present. This study will use the multivariate model of machine learning method, detection brain activation patterns under different situations among patients with violence. The investigators are going to study imaging biomarkers, and try to predict the possibility of onset of violence among schizophrenia patients, thus reduce the risks of violence.

Animal-assisted therapy (AAT) can be helpful to improve the psychiatric, emotional, physical,and social status in patients with physical and mental illness and the elderly. The study aims to investigate the effects of AAT program in middle-aged and older patients with schizophrenia. The investigators will recruit 40 patients with schizophrenia in psychiatric ward randomised into AAT group and control group. AAT group will complete the 12-week program. This study contains two assessment sessions before and after intervention, including PANSS, ACIS, MoCA-T, CHI, DASS‐21, CST, TUG and 5MWT.
