Filter by:The purpose of this study is to investigate the efficacy of IPS in Denmark and compare effects of 1. Individual Placement and Support (IPS) vs. 2. IPS + cognitive remediation and work-related social skills training vs. 3. standard intervention, among individuals with severe mental illness.
The purpose of this study is to determine if EVP-6124 (an alpha-7 nAChR agonist) enhances the cognitive abilities of subjects with Schizophrenia who are also taking stable antipsychotic therapy.
Accumulating evidence suggests a role of oxidative stress in the pathophysiology of schizophrenia. The potent antioxidant sulforaphane (SFN) is an organosulfur compound derived from a glucosinolate precursor found in cruciferous vegetables such as broccoli, Brussels sprouts and cabbage. The protection afforded by SFN is thought to be mediated via activation of the NF-E2-related factor-2 (Nrf2) pathway and subsequent up-regulation of phase II detoxification enzymes and antioxidant proteins, through an enhancer sequence referred to as the electrophilic responsive element or antioxidant responsive element. Recently, we reported that SFN could attenuate behavioral abnormalities in mice after the NMDA receptor antagonist phencyclidine. Considering the potent antioxidant effects of SFN, we have a hypothesis that SFN would be a potential therapeutic drug for schizophrenia. The purpose of this study is to determine whether SFN-rich broccoli sprout extract have beneficial effects in patients with schizophrenia.
This study is being conducted to further investigate the safety of prolonged exposure to EVP-6124 in subjects with Schizophrenia receiving a stable dose of an atypical antipsychotic who completed double-blind treatment on studies EVP-6124-015 and EVP-6124-016.
The purpose of this study is to determine if EVP-6124 (an alpha-7 nAChR agonist) enhances the cognitive abilities of subjects with Schizophrenia who are also taking stable antipsychotic therapy.
Introduction: Schizophrenia is a serious mental illness. For majority of patients it is a lifetime condition,characterized by intermittent episodes of hospitalization due to relapse or acute symptom exacerbation. The nature and course of the disorder impose significant social and economic burden. Relapse is costly, with hospitalization accounting for a substantial portion of healthcare expenses. Second generation antipsychotic side effect such as metabolic syndrome and diabetes mellitus will contribute additional costs to the treatment. Many studies have since then provided convincing evidence for a high risk of diabetes and other glucose abnormalities, metabolic syndrome and mortality due to elevated cardiovascular risk in patients with schizophrenia. However many studies has shown the effectiveness and safety of aripiprazole and ziprazidone.In one of the study, aripiprazole showed improvement of negative schizophrenic symptoms by 25% and 50% of functioning level from baseline. In term of safety, antipsychotics considered to have a safer metabolic profile were amisulpride, ziprasidone and aripiprazole. Study objectives: - To investigate the safety and efficacy of ziprazidone versus aripiprazole in the treatment of schizophrenia patients with metabolic syndrome and diabetes mellitus. - To investigate the reversibility of metabolic syndrome and diabetes parameters following the treatment with ziprazidone versus aripiprazole. Hypotheses: * The proportion of reversibility of metabolic syndrome and diabetes parameters is higher following the treatment of ziprazidone than aripiprazole.
The main objective of this study is to determine the preliminary efficacy of Paranoia-Focused Cognitive Behavioral Therapy (PFCBT) relative to standard care in the treatment of persecutory delusions in patients diagnosed with schizophrenia or schizoaffective Disorder.
Cognitive Remediation Therapy (CRT) can enhance cognitive performance in schizophrenia improving functional outcome. But most of the studies have involved participants who are in average in their mid 30s, and little is known about the efficacy of CRT in adolescents with early-onset schizophrenia (EOS). The aim of this study is to investigate efficacy of CRT in improving cognitive performance and functional outcome in adolescents with EOS. We expect to find that CRT improves cognitive and functional outcomes in adolescents with schizophrenia.
Background: A large body of research has shown that Oxytocin (OXT) is an important prosocial peptide and there is also initial evidence that the central OXT system is altered in several mental disorders that are characterized by severe social disturbances and deficits, such as anxiety disorders with prominent social dysfunction (e.g., schizophrenia), mood disorders and borderline personality disorder. OXT may reduce psychotic symptoms and may diminish certain social cognition deficits that are not improved by current antipsychotic medications. Aims: The project has two main aims, listed below: 1. To assess the efficacy of intranasal OXT in reducing negative symptoms in patients with schizophrenia in association with second-generation antipsychotics (SGA); 2. To use an Emotional Priming Paradigm task to assess pre- and post-treatment change in the patients general cognitive and emotional status. Study Design: Randomized, double-blind, placebo-controlled, cross over design. Materials and methods: Patients involved in the study will be recruited in six centres in the north of Italy. Each subject (aged 18-45, with a duration of the disorder no longer than 10 years) will be enrolled after a screening phase. 80 patients will be randomly assigned to either 40 IU OXT once daily or vehicle placebo, in addition to their pre-study antipsychotic medication regimen: all reasonable attempts maintain the same SGA dosages throughout the study will be made. The study ratio is 1:1. The total study duration for each individual subject will be approximately 8 months, which includes an up to 7-day screening period, a baseline randomization visit, and a four month long cross-over treatment period. Subjects will be trained by researchers about the self-administration of intranasal OXT. A trustworthy caregiver will be trained as well. Each patient will receive every morning a SMS text message on his mobile phone as a reminder for OXT administration. Before starting the treatment, all patients will be assessed with standardized assessment instruments and will undergo an in depth neuropsychological assessment; additional evaluations, including safety evaluations, will be performed at 4 and 8 month follow-ups. The primary outcome measure will be the negative score in the Positive and Negative Syndrome Scale (PANSS) performed at 2,4,6 and 8 months since the start of the treatment.
The aim of this study is observation of effectiveness and side effect of patients with schizophrenia who will switch the antipsychotics from risperidone long acting injection to paliperidone palmitate.
