Active clinical trials for "Schizophrenia"

Investigators plan to explore whether Omega-3 fatty acid have effect on the violent behavior of the schizophrenia patients. Investigators will use PET to explore the influence on serotonin function of the brain to understand the mechanism of how Omega-3 fatty acid works. This study will enroll 100 patients of schizophrenia with violent behavior.Participants will be split into two groups randomly. In one group, participants will receive one pill of placebo per day, and in the other, participants will have one pill of 900mg Omega-3 fatty acid per day. This intervention will last 3 months.At week 0, week 4, week 8 and week 12, some scales will be evaluated. Meanwhile, the density of eicosapentaenoic acid(EPA),docosahexaenoic acid (DHA),noradrenalin(NE), dopamine(DA) and serotonin(5-HT) in blood will be tested.At week 0 and week 12, 10 patients of each group will be randomly selected to have the exam of PET.

The primary goal of the present study is to evaluate the utility of mGluR5 binding as measured by PET as a biomarker of the CNTNAP2 mutation and related /mTOR kinase pathway dysregulation.

The purpose of the study is to test a new treatment of social cognition deficits in patients with schizophrenia or schizoaffective disorder by transcranial magnetic stimulation (theta-burst). The study will also identify clinical variables, cognitive and psychomotor most sensitive to treatment, to estimate the most sensitive treatment target, assess tolerance, to assess the impact of repetitive Transcranial Magnetic Stimulation (rTMS) on the brain a multimodal imaging study and compare the imaging variables (resting network, Diffusion Tensor Imaging, magnetic resonance spectroscopic imaging; MRSI) between patients before treatment and healthy subjects.

Efficacy and safety of Tandospirone combined with Atypical Antipsychotic drugs to Improve Cognitive function in Schizophrenia

In the current study, the investigators propose to measure the five domains of social cognition identified by the National Institute of Mental Health (NIMH) as relevant to individuals with psychosis (i.e., theory of mind, attribution style, emotion recognition, social perception, and social knowledge). The investigators will also explore the association between different domains of social cognition and outcomes relevant to psychotic disorder (e.g., symptomatology, social functioning, and vocational functioning).

D2 dopaminergic receptor blockers, used to treat schizophrenia, can lead to the onset of movement disorders. Drug-induced movement disorders encompass several syndromes. Parkinsonism, dystonia, dyskinesia and akathisia are the most prevalent. All of them lead to poor adherence to the treatment instituted, decrease in the quality of life, relapses and hospitalizations. The pathophysiology of drug-induced movement disorders is complex and poorly understood, but seems to be associated with oxidative stress, as a result of an increase in free radicals generated from dopamine metabolism. Treatment strategies following the onset of drug-induced movement disorders include neuroleptic discontinuation, use of atypical antipsychotics and anticholinergics. A pre-clinical study showed that the antioxidant properties of vitamins B6 and B12, alone or in combination, prevented the development of orofacial dyskinesia induced by haloperidol. This clinical trial aims to evaluate the effects of vitamins B6 and B12 on the treatment of patients diagnosed with schizophrenia, schizoaffective or bipolar disorder who present with tardive dyskinesia, dystonia and parkinsonism.

The title of this study is a multi-center,non randomized,open-labeled,intervention study:the efficacy and safety of intramuscular ziprasidone for three days in patients with acute psychotic agitation. The primary objectiveis to evaluate the efficacy of intramuscular ziprasidone in patients with acute psychotic agitation in daily clinical practice. The secondary objectives are:1.To evaluate the safety of intramuscular ziprasidone in patients with acute psychotic agitation in daily clinical practice.2.To compare the efficacy and tolerance of intramuscular ziprasidone in patients with agitation in the different psychotic disorder 3.To compare the efficacy and tolerance of intramuscular ziprasidone in patients with first episode andmulti-episode patients. 4.To explore the measured based administration according to severity of symptoms.5.To compare the efficacy and tolerance of ziprasidone im between the monotherapy and combination with other antipsychotic drug in clinical practice. The Rationale:In China, the studies of ziprasidone im treating agitation focus on schizophrenia. But in the foreign country, ziprasidone im also is approved to treat psychotic agitation, including bipolar and schizoaffective disorder. And in the clinical practice of China, ziprasidone im is also used to treat other patients, although the evidence is less. In this study, we assume ziprasidone im treat the psychotic agitation is effective and safe. Study populations:The study plan to enroll 1000 subjects in China. （6）The background and the hypothesis：The researches of ziprasidone mesylate injection in our country are more concentrated in schizophrenia at present, while in foreign countries ziprasidone is approved for psychotic agitation, including mania etc. It's also used for substance abuse and alcohol induced agitation.Therefore, this study assumes that ziprasidone mesylate injection is effective in the treatment of acute agitation, and it's well tolerated.

Schizophrenia is a severe psychiatric condition that is associated with significant distress and disability. In addition to cognitive difficulties in domains such as attention, memory, and problem-solving, individuals with schizophrenia can experience visual-processing abnormalities, including impairments in visual acuity, low-contrast stimulus detection, and perceptual organization (i.e., perceiving visual information in an organized "perceptual whole"). These visual impairments are clinically significant, with research indicating that specific visual-processing alterations are significantly related to poorer performance on higher-level cognitive tasks, impaired facial emotion recognition, impaired reading ability, and worse functional outcomes. Despite such findings, very few studies have evaluated the therapeutic potential of interventions that are specifically designed to improve visual processing ("visual remediation") for individuals with schizophrenia. Thus the aim of this study is to evaluate the efficacy of a computerized visual perceptual training program that targets low- and mid-level visual processes to improve visual, cognitive, and emotion-recognition functions in outpatients with schizophrenia through a small randomized controlled trial. The investigators will recruit up to 40 individuals with schizophrenia or schizoaffective disorder who are receiving treatment in Rutgers University Behavioral Health Care (UBHC) Partial Hospital Program; half will be randomized to receive the computerized visual training, which will be delivered in small groups over a period of 12-14 weeks. The specific aims of this study are to collect preliminary data on: 1) the feasibility of participant recruitment and retention, and tolerability of the treatment components of the study; and 2) the efficacy of computerized visual training (VT) to improve low- and mid-level visual processes, and higher-level cognitive and social-cognitive performance. Based on preliminary data, the investigators hypothesize that the target number of participants will be successfully recruited and engaged in the VT intervention (n=16) and control condition (n=16), and that the participants who receive VT will demonstrate greater improvements on measures of low- and mid-level visual, higher-level cognitive, and social-cognitive functions compared to those who receive standard partial-hospital care without VT. The results of this initial trial will be used to inform the design and application for funding of a larger-scale investigation of visual remediation for individuals with schizophrenia.

The treatment of schizophrenia is challenging as the existing medications improve only the positive symptoms with the limited benefit on cognitive and negative symptoms which have a large bearing on the functional outcome. Recent research has suggested the association of low level of vitamin D with schizophrenia but studies are few and marred by mixed results. Thus, we propose to evaluate the effect of weekly vitamin D3 supplementation in patients with first-episode schizophrenia through a randomised doubled blind placebo controlled design.Fifty-six participants of either sex (19 - 50 years) with schizophrenia having vitamin D insufficiency/deficiency (< 30 ng/ml) will be randomly supplemented with Vitamin D3 or placebo for 8 weeks in 1:1 pattern. The clinical treatment i.e., antipsychotic medications will be continued as usual within the two groups. Participants in both the groups will be assessed at study entry, at the end of the 04 and 08 weeks (after completing supplementation) on the Positive and Negative Syndrome Scale (PANSS), Computerized Neurocognitive Battery (CNB) & Clinical Global Improvement (CGI) subscale (CGI-I). Raters will be blind to the group assigned to participants. Side effects will be monitored at every visit. The serum levels of vitamin D will be measured at baseline and at the end of 08 weeks.

This study compares the efficacy and effectiveness of two of the second-generation antipsychotics (SGAs) most used in our society in the treatment of schizophrenia (Aripiprazole and Risperidone) and the investigators do within an assistance program of early-stage psychosis individuals of the Community of Cantabria, clinical reference for the treatment of this disease in the Spanish Autonomous Community. Patients are included in a prospective naturalistic study, open flexible-doses and randomized into one of two possible patterns of treatment that includes the protocol.
