Filter by:This research on cognitive training addresses the following questions: 1. Does cognitive training lead to improved cognition, functional abilities, psychiatric symptoms, treatment adherence, or quality of life in patients with psychoses? 2. What are the neurocognitive and non-cognitive factors that predict good outcomes following cognitive rehabilitation? In addition to verbal learning and memory, immediate verbal memory, vigilance, and executive functioning, the cognitive training intervention attempted to improve prospective memory ability (i.e., the ability to remember to do things in the future, such as take medications or attend a doctor's appointment).
The investigators propose to recruit individuals with schizophrenia who are symptomatically stable and already taking medications to participate in this study. The investigators will recruit 90 individuals with schizophrenia and randomize them to low and high doses of DAR-0100A, as well as to placebo. The investigators will have them stay in the hospital for several weeks and receive up to 10 doses of DAR-0100A. The investigators will also test their cognition before and after receiving DAR-0100A to see if DAR-0100A is helpful and perform MRI scans before and after taking the medication to see which areas of the brain are activated when DAR-0100A is administered. These tests will be very important because they will help the investigators determine whether the D1 receptor is a good treatment target for schizophrenia and whether more research and resources should be devoted to finding medications that target this system. Patients with schizophrenia will be free of other medical, psychiatric and neurological disorders including alcohol and substance dependence, and will be able to understand the nature of the study and to provide informed consent.
To evaluate the safety and tolerability of multiple, ascending doses of PF-04958242 administered orally to psychiatrically stable subjects with schizophrenia receiving antipsychotic and adjunctive medication.
This study will evaluate whether oxytocin will facilitate the learning of social cognitive skills in schizophrenia patients who receive 12 sessions of Social Cognitive Skills Training (SCST). The primary hypothesis is that schizophrenia subjects who are treated with oxytocin will demonstrate greater improvements in a summary measure of social cognition than subjects treated with placebo over the course of SCST.
A Randomized, Double-blinded, Double-dummy, Parallel-controlled and Multicenter Clinical trial to Investigate Blonanserin in Treatment of Schizophrenia when compared with Risperidone
The purpose of this study is to demonstrate that a paliperidone palmitate 3 month formulation (PP3M) is as effective as the paliperidone palmitate 1 month formulation (PP1M) in the treatment of patients with schizophrenia who have been stabilized on PP1M.
Despite current antipsychotic treatment, the majority of people with schizophrenia continue to exhibit persistent positive and negative symptoms and cognitive impairments. An alternative approach to the use of psychotropic agents for the treatment of persistent symptoms is the use of anti-inflammatory agents to reverse the pro-inflammatory state hypothesized to underlie the symptom and sign manifestations of the illness. The investigators primary hypothesis is that add-on anti-inflammatory combination therapy will have significant beneficial effects on persistent positive symptoms and cognitive impairments. The investigators secondary hypotheses are: 1. add-on anti-inflammatory combination therapy will be associated with improvements in depressive and negative symptoms and a reduction in pro-inflammatory cytokines 2. add-on anti-inflammatory combination therapy compared to placebo will not be associated with elevated adverse risk.
Schizophrenia beginning before 18 years is a clinical entity not well known because of its low incidence and difficulties in the clinical diagnosis. However, in the investigators clinical practice, due to the specialization of the investigators service, the investigators are led to hospital to receive important feel active of patients meeting the Diagnostic and Statistical Manual of Mental Disorders IV text revision (DSM IV-TR) precose schizophrenia. The work of us team on the theme of the relationship between Pervasive Developmental Disorders and precose Schizophrenia led us to hypothesize that a number of children in care in the medical and educational institutes, hospitals and day shelters therapeutic part-time symptoms of schizophrenia or a line real early diagnosis of schizophrenia undervalued or not diagnosed. The main goal is to estimate the prevalence of dissociative disorders in a population of children in care institutions and medical education in child psychiatry in hospitals and others structures.
Auditory verbal hallucinations (AVH) are a characterising symptom of schizophrenia. In the majority of patients, these AVH respond well to antipsychotic medication. Yet, a significant minority continues to experience frequent AVH despite optimal pharmacotherapy. The number of alternative treatment options for this medication resistant group is currently low and most of them focus on coping with the hallucinations. Transcranial magnetic stimulation (TMS), in contrast, is a non-invasive technique of influencing cortical excitability. This technique has the potential to actually decrease the frequency and severity of medication resistant hallucinations. Several previous studies have assessed efficacy of low frequency rTMS, with contradicting results. A previous large study by the investigators group could not demonstrate efficacy of low frequency rTMS. A new stimulation protocol using theta burst rTMS (TBS) could provide a more effective therapeutic option. Objective: The present study aims to examine the efficacy of TBS on the severity of AVH. Study design: The objectives are tested in a randomized double blind placebo-controlled trail. Study population: 60 patients with the diagnosis of schizophrenia, schizoaffective disorder, schizophreniform disorder or psychosis not otherwise specified with frequent auditory verbal hallucinations will be included. Intervention: The participant will receive either 10 TBS treatments or 10 placebo treatments consisting of 900 pulses each with a 30 minute interval on the left temporoparietal area, distributed over 5 treatment days. Stimulation will be at 80% of the motor threshold. Main study parameters/endpoints: the main study parameter is the change in the severity of the AVH. The secondary study parameter is the number and severity of adverse events.
This study aims to assess the safety, tolerability, and pharmacokinetics of PF-04958242 at a number of ascending doses administered once daily for 14 days in healthy volunteers.
