Filter by:rTMS and MEG for auditory hallucinations via self controlled clinical trials. Repetitive transcranial magnetic stimulation (rTMS) can increase or decrease cortical excitability in patients with psychosis (such as schizophrenia). Here, we conducted an open clinical trial on 60 schizophrenics with auditory hallucinations. We searched for targets through magnetoencephalography and then intervened to prove that rTMS guided by magnetoencephalography is effective for auditory hallucinations.
In this randomized double-blind trial, the investigators aim to investigate whether online high definition transcranial direct current stimulation (HD-tDCS) over the left dorsolateral prefrontal cortex (DLPFC) during a working memory task improves the severity of negative symptoms in schizophrenia patients with predominant negative symptoms.
Our proposed study employs a novel approach to determine the clinical and functional imaging effects of brainstem neuromodulation, with an investigational study device, on illness awareness in schizophrenia - a significant contributor to medication non-adherence and poor treatment outcomes, and arguably the most treatment resistant manifestation of the disorder. The study device under investigation provides a safe and non-invasive method of brainstem stimulation that will be used in conjunction with a neuroimaging biomarker to measure brain changes associated with treatment and illness awareness.
Background: Presence of a series of typical physical symptoms is an enduring and functionally relevant feature of early-onset schizophrenia (EOS). Psychotherapy improves clinical symptoms in adults with schizophrenia, although data in adolescents with EOS remain scarce. The purpose of this study is to examine the efficacy of the adapted group psychotherapy in improving clinical symptoms from a perspective of neuroimaging in a sample of symptomatically stable adolescents with EOS. Methods: Investigators conducted a double-blind randomized controlled trial using multidomain, adaptive, group psychotherapy in 28 EOS patients, who were randomly allocated into either training (group psychotherapy) or active control (health education) groups. Data of diffusion tensor imaging, and clinical symptoms were obtained at baseline and after an average of 2 hours/day, 2 days/week for 4 weeks of intervention.
Internalized stigma, (i.e. the application of negative stereotypes about a diagnostic group to one's self) is a strong predictor of recovery and quality of life for individuals with psychosis. Be Outspoken and Overcome Stigmatizing Thoughts (BOOST) is an evidence-based intervention aimed at improving internalized stigma, self-esteem, and quality of life for those with psychosis. The proposed research expands BOOST's program by adding additional therapeutic methods and material, and adopting the use of virtual care methods to: (a) increase the generalization of treatment effects, (b) examine long-term treatment effects, and (C) provide rural Ontario communities with remote treatment access.
This study is to determine the tolerability and efficacy of an accelerated schedule of Transcranial Magnetic Stimulation for treating symptoms of psychotic disorders such as schizophrenia.
Brief Summary: Definition: A short description of the clinical study, including a brief statement of the clinical study's hypothesis, written in language intended for the lay public. Limit: 5000 characters. The purpose of this study is to investigate the relationship between speech features and severity of positive and negative clinical symptoms in Arabic speaking patients with schizophrenia. Individuals will be invited to participate in this study because (1) they have a confirmed clinical diagnosis of schizophrenia; (2) they plan to receive routine clinical care for schizophrenia at one of the four participating sites; (3) they speak Arabic as a first language. Participants must be between the ages of 18-65 years. Participation will involve seven visits consisting of one baseline visit and six monthly follow-up visits. All participants will continue to receive routine clinical care. Participation in this research will involve providing speech samples using standardized tasks collected using an electronic device. Additionally, study team members will assess positive and negative symptoms of schizophrenia using validated questionnaires.
The overall aim of this study was to develop a meta-cognitive group intervention in order to apply it and to understand and distinguish the components that influence participation among people with schizophrenia
Repetitive transcranial magnetic stimulation (rTMS) can alleviate persistent auditory verbal hallucinations (AVH) in schizophrenic patients, but the classical procedure with low-frequency stimulation for several weeks upon the left temporoparietal junction have shown modest therapeutic effects, and there is currently no robust predictive factor to the response of the treatment. In a previous multicentric, randomized, and double-blind controlled study, it has been demonstrated that a high-frequency rTMS over an anatomical target can rapidly affect AVHs. Moreover, an intensification of the classical procedure delivering 20-Hz rTMS over a 2-day period was used in addition to a personalized anatomical stimulation target and neuronavigation guidance. Besides the significant efficacy of the procedure, the efficacy was maximal at two weeks after the end of the treatment. In this project, the hypothesis is that the two-day cure could benefit from maintenance rTMS sessions every week for one month and then every two weeks for 3 months to provide an optimal strategy for a long-lasting AVH reduction. This has for now never been tested. Predictive factors to the response of the treatment are also investigated.
This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, multi-arm, multi-stage inpatient study designed to assess the efficacy, safety, tolerability, and pharmacokinetics (PK) of NBI-1117568 compared with placebo in adult subjects with a primary diagnosis of schizophrenia, who are experiencing an acute exacerbation or relapse of symptoms.
