NCT ID: NCT03971487 Recruiting - Schizophrenia Clinical Trials

Ocrelizumab for Psychosis by Autoimmunity

OPA
Start date: October 1, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Some people who have what doctors currently call schizophrenia or bipolar disease may actually have a brain disease caused by auto-antibodies. Auto-antibodies are produced when the normal defense mechanism of the body goes wrong and begins to attack the body, similar to "friendly fire." Auto-antibodies attack brain receptors and then the person who has this problem begins to have hallucinations and other manifestations of schizophrenia, like feeling that people can see what they are thinking and also feeling that other people do not like them. If this disease is caused by auto-antibodies, typically the person is well until they are 15 years of age or older, but seldom older than 35 years. Then, in a matter of a few months they begin to have hallucinations and the other symptoms. Doctors still do not know whether some people with schizophrenia or bipolar disease have auto-antibodies attacking their brain. For this reason, in this study some of these patients will receive a treatment that suppresses the auto-antibodies and their symptoms after treatment will be compared with the symptoms of a group of similar patients who are given a preparation that looks like the real treatment, but it is not.

Study on Predictiors and Mechanism of Conversion to Psychosis in Individuals at Ultra-high Risk Group

Start date: November 1, 2016
Phase:
Study type: Observational

Considering the complex pathological mechanism and the poor treatment outcomes of schizophrenia, early detection and intervention gradually become the key work for the foundational and clinical research in schizophrenia. Ultra-high risk for psychosis (UHP) is defined as individuals at the prodromal stage of schizophrenia. Early intervention in individual at UHP can effectively delay or even prevent the development of the illness. Long-term longitudinal studies suggested that there are clinical outcomes in people at UHP. Nearly 1/3 of individuals at UHP may be naturally relieved without any intervention, about 1/3 of individuals at UHP will remain at the prodromal stage of schizophrenia, and only 1/3 individuals at UHP will eventually develop schizophrenia. In this regard, it will cause adverse effects on false positive individuals if they accept clinical intervention. Unfortunately, it is difficult to accurately predict which individuals at UHP will make a transition to frank illness. To solve this issue, we explore the association between baseline brain structural and functional networks, methylation modifications, gene expression, neurocognitive function and the clinical outcomes of UHP individuals, and to identify the potential biological and clinical predictors for the long-term outcomes in the individuals at UHP. In addition, we also detect the changes of brain structure and function, methylation status and gene expression in individuals at UHP during follow-up, and further to investigate the etiology and pathogenesis of schizophrenia.

Early Psychosis Intervention - Spreading Evidence-based Treatment

EPI-SET
Start date: January 3, 2020
Phase:
Study type: Observational

Implementation of 'NAVIGATE' in Ontario aims to help youth and emerging adults suffering from a first episode of psychosis. Although Ontario already has early psychosis intervention programs, the team's recent work has identified major challenges of delivering coordinated care, particularly those elements of care that enhance recovery. These challenges also exist nationally and internationally. By building on the already existing early psychosis intervention community of practice through the Early Psychosis Intervention Ontario Network, the investigators will implement NAVIGATE with the help of CAMH's Provincial System Support Program facilitators. The use of tele-videoconferencing through ECHO Mental Health Ontario and ECHO processes and protocols provide us with an opportunity to ensure sustainability. Using health administrative data held at the Institute for Clinical Evaluative Sciences (ICES), the investigators can examine system-level outcomes, including hospitalizations, emergency department visits, and outpatient physician visits of youth and emerging adults suffering from a first episode psychosis who are treated with NAVIGATE compared with those treated in early psychosis intervention programs without NAVIGATE and those who are not treated in early psychosis intervention programs. In addition, the investigators can also evaluate health care costs. Prior to initiating this project, the investigators obtained the input of youth and emerging adults with a first episode psychosis and family members. The investigators will also continue to measure engagement across the study. Hypotheses: 1. Following the implementation of NAVIGATE, program fidelity (i.e. adaptability) to the Ontario early psychosis intervention standard will improve. 2. Compared to patients not receiving NAVIGATE, those who receive NAVIGATE through this implementation study will have fewer days in hospital, fewer emergency department visits, fewer suicide attempts, lower mortality, and lower healthcare costs. 3. Improvements in functioning and symptoms will be comparable to the RAISE study (an earlier study assessing NAVIGATE); improvement may be influenced by demographic, socio-economic, geographic, and clinical factors. 4. The project's engagement approach will demonstrate that the investigators used the full range of patient engagement based on objectively assessed engagement metrics.

NCT ID: NCT03911726 Recruiting - Schizophrenia Clinical Trials

Do Antipsychotic Agents Induce Supersensitivity in Humans: A Combined PET/MRI Study in Patients With Schizophrenia

Start date: August 1, 2020
Phase: N/A
Study type: Interventional

The aim of the present study is to detect changes in the dopamine system in the brain of patients with schizophrenia, especially when pretreated with antipsychotic medication. Here, the investigators want to find out whether the treatment with these drugs can cause permanent changes in docking points (receptors) of dopamine in the brain. It will be examined whether number and response of dopamine receptors is altered, which are associated with the onset of psychotic symptoms. For this purpose, a single PET/MR measurement will be performed in all participants. In total 140 volunteers, consisting of 30 healthy volunteers, 20 first-episode, drug-naive patients with schizophrenia and 90 pretreated patients with schizophrenia will be included over a time period of three years. In addition, the influence of nicotine consumption on dopamine receptors will be invesitgated by comparing data from smoking and non-smoking patients. In clinical practice, an elevation of dopamine action caused by alterations in receptors in the brain is of most importance. This may be the reason why the treatment with antipsychotic agents does not work in some patients. In addition, a permanent elevation of dopamine action is associated with permanent brain alterations by these drugs. The result can contribute to work out valuable indications, whether it makes sense to continue a long term therapy with antipsychotic drugs in a patient. But also the in-depth understanding of the impact of nicotine on the course of therapy can help to open up possibilities for improved drug treatment.

NCT ID: NCT03873922 Recruiting - Schizophrenia Clinical Trials

Ketogenic Diet for Psychotic Disorders

PsyDiet
Start date: March 15, 2021
Phase: N/A
Study type: Interventional

Disturbances in glucose metabolism and glutamate neurotransmission feature in the pathophysiology of psychotic disorders. Ketogenic diet (KD) is a high-fat, low-carbohydrate diet that restricts glucose and forces metabolism of ketones, which serve as alternative energy substrates for the brain. KD is an established treatment for intractable epilepsy. However, we lack the randomized controlled trials (RCT) evidence regarding potential effects of KD on psychotic symptoms in humans. This randomised, controlled pilot study aims to investigate: 1. feasibility of a Modified Ketogenic Diet (MKD) intervention protocol in psychotic inpatients, 2. potential impact of MKD intervention on psychotic symptoms, depressive and anxiety symptoms, and functioning in patients with psychotic symptoms / psychotic disorder. A 6-week randomised KD pilot study will be carried out in psychotic inpatients (aimed n=40) at Niuvanniemi Hospital and Kuopio University Hospital, Finland. In the KD group, carbohydrate consumption is limited to 15-20 g/day to activate ketosis. The control group will have their ordinary hospital meals. A number of different assessment will be carried out at time points 0, 1 week, 3 weeks and 6 weeks.

NCT ID: NCT03862209 Recruiting - Schizophrenia Clinical Trials

NCT ID: NCT03814967 Recruiting - Schizophrenia Clinical Trials

Effects of Brain Stimulation on Higher-Order Cognition

Start date: May 22, 2019
Phase: N/A
Study type: Interventional

The purpose of this study is to better understand the neural correlates of higher-order cognition, both in the healthy brain and in schizophrenia, and to determine how these mechanisms are modulated by transcranial direct current stimulation (tDCS) at frontal and occipital scalp sites. Testing the effects of tDCS at these scalp sites on cognitive task performance will help us understand the roles of the brain regions corresponding to these sites during higher-order cognitive processing (language comprehension, cognitive control, and related attention and memory processes). Behavioral and electrophysiological (EEG) measures will be used to assess cognitive performance. The investigator's overarching hypothesis is that stimulating prefrontal circuits with tDCS can improve cognitive control performance, and ultimately performance on a range of cognitive tasks, as compared to stimulating a different cortical region (occipital cortex) or using sham stimulation. This study is solely intended as basic research in order to understand brain function in healthy individuals and individuals with schizophrenia. This study is not intended to diagnose, cure or treat schizophrenia or any other disease.
