Filter by:The aim of this study is to investigate the effects of non invasive brain stimulation - NIBS - techniques (Electroconvulsivotherapy - ECT, transcranial Direct Current Stimulation - tDCS, repetitive transcranial magnetic stimulation - rTMS) on serum Brain Derived Neurotrophic factor (BDNF) levels in patients with depression and schizophrenia. Four blood samples will be collected in each participants, one before the NIBS sessions, and 3 after the completion of NIBS protocols: one immediately after the end of the NIBS sessions, a second one week after and a last one month after. Two blood samples separated by one month will also be collected in a a group of healthy volunteers.
The aberrant expression of micro-RNAs (miRNAs) has been described in many human diseases, including schizophrenia (SZ). The previous work has indicated a strong genetic association between the miRNA-30e precursor (pre-miR-30e) and the risk of SZ. However, to date, few reports have focused on the expression level of the miR-30 family (miR-30s) and its networks of co-regulation in SZ, even in response to antipsychotic treatment. Given this, the investigator first constructed a hybrid miRNA-TF (transcription factor)-gene-PPI (protein-protein interactions) network focusing on miR-30s by bioinformatics technology. The investigator then selected several candidate miR-30s and key regulators for further validation. These candidates were then quantified by real-time quantitative PCR (qRT-PCR) in an independent cohort of 200 healthy controls and 200 drug-free SZ patients, among which were followed up by 12-week antipsychotic treatment. Furthermore, the investigator evaluated the correlation between the change in gene expression and the improvement of symptoms.
Levetiracetam (LEV: (S)-α-ethyl-2-oxo-pyrrolidine acetamide) is an anticonvulsant/antiepileptic drug. The specific aim of this study is to assess the efficacy of low-dose LEV in reducing hippocampal activity in schizophrenia. The investigators also hypothesize that LEV will improve neurocognition in participants with schizophrenia.
This multi-centre study will evaluate the safety and related factors study of atypical antipsychotics long-term treatment in Chinese Patients with Schizophrenia. The atypical antipsychotics include quetiapine, olanzapine, risperidone, aripiprazole, ziprasidone, paliperidone , amisulpride , perospirone and clozapine. This is an open, cohort, multi-center observational clinical study. The main purpose is to evaluate the safety. And the second purpose is to evaluate the efficacy of atypical antipsychotics. The efficacy evaluations include symptoms, social function, recurrence rate and hospitalization. This study belongs to IV period post-marketing drugs research. Planned sample size is 3000 cases. Visits occurs at 0,4,8,13,26,52,78,104,130 and 156 weeks. The main indexes include physical examination, vital signs, abdominal circumference , laboratory tests (blood cell analysis/ blood biochemical tests / prolactin (PRL) / thyroxine, etc.), adverse events, 12-lead electrocardiogram( ECG), extrapyramidal syndrome(EPS )assessment, sexual function evaluation, medication and other subjective feelings. The second indexes include scales of Positive and Negative Syndrome Scale(PANSS)，Clinical Global Impression-severity of Illness Scale(CGI-S), Calgary Depression Scale for Schizophrenia(CDSS),Personal and Social Performance Scale(PSP), the MOS 36一item Short Form Health Survey(SF-36), relapse rate, drug consolidation, medical-related expenses, income, drug plasma concentration and genetic information.
Plasma half-life has routinely been used to establish the dosing schedule of antipsychotics; for example, it is recommended that agents with a short plasma half-life be administered multiple times per day. However, to date, several randomized controlled trials (RCTs) have shown no differences in clinical outcomes between once- and twice-daily dosing of various antipsychotics, suggesting that once-daily dosing of antipsychotics is a viable option regardless of plasma half-life. This would apply to clozapine as well; however, there have been no studies comparing once-daily vs. twice-daily dosing regimens of clozapine in terms of efficacy and tolerability. To address this gap in the literature, the investigators shall conduct a pilot, double-blind, RCT to examine efficacy and tolerability following a switch to once-daily dosing regimen of clozapine in patients with schizophrenia receiving clozapine twice a day.
The Joint Crisis Plan = SOS Plan is a reference to a particular form of psychiatric advance directive which involves the patient, the healthcare team, their relatives and a third party caregiver as intermediary for the project. The main objective is to evaluate the effectiveness of the SOS Plan (JCP) in terms of the reduction in hospitalisations within 18 months of its development by comparison to the standard psychiatric care. Thus, the investigators' proposal is that SOS Plan's are regularly reassessed every 6 months and again where there is an unplanned psychiatric readmission that lasts beyond two weeks. Single blind multicentre randomised trial with parallel control groups. Effectiveness study of a psychiatric care strategy.
The purpose of this trial is to explore parent-child interactions in parents with and without psychosis, and ascertain whether a brief (10 week) supported self-help parenting program offered to parents in their own homes can help improve parents' self-efficacy and general well-being, as well as interpretations of their parent-child relationship and child behaviour in children who are 3-10 years old.
The purpose of this study is to investigate the effect of a neuroplasticity-based computerized cognitive training for people with schizophrenia in the Brazilian population.
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.
This a randomized double-blind placebo controlled trial which aims to determine the beneficial effects of minocycline augmentation to clozapine in partial responders to Treatment Resistant Schizophrenia (TRS).
