Filter by:The purpose of the study is to investigate the effect of a 30 hour cognitive remediation program for young patients with early phase schizophrenia spectrum disorders on cognitive, clinical and functional outcome measures. The remediation program is integrated with whatever active rehabilitation the participant is currently attending (school, work, day program etc).
As in the general population, there is no clear standard of care within Veterans Affairs Medical Centers for treating posttraumatic stress disorder (PTSD) among individuals with severe mental illness (SMI). This is a considerable issue because trauma, posttraumatic stress disorder (PTSD), and severe psychiatric comorbidity are particularly common among Veterans and this symptom presentation clearly exacerbates the overall course and severity of mental illness. This study is significant in that it proposes to establish the efficacy of a frontline exposure based intervention for posttraumatic stress disorder (PTSD), Prolonged Exposure, for improving critical clinical, quality of life, and cost outcomes among Veterans with severe mental illness (SMI) enrolled in VA healthcare. Collectively, it is anticipated that these data will establish a much needed clinical course of action for what is considered a vulnerable yet highly underserved patient population.
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.
The objective of this study is to evaluate the efficacy and safety of RP5063 relative to placebo for the treatment of schizophrenia or schizoaffective disorder.
Persons with serious mental illness (SMI) are at increased risk of cardiovascular disease (CVD). The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and improve mental health and physical health-related quality of life, as well as to get feedback from patients and providers on what is needed to help better coordinate the physical and mental health care of these patients.
The aim of this project is to investigate the effect of Raloxifene 120mg in men with schizophrenia. This trial will adopt a 12 week randomised controlled model. Hypotheses 1: That the men receiving adjunctive selective estrogen receptor modulators (SERM) will have a significantly greater reduction in psychosis symptoms over the course of the study than men receiving adjunctive placebo. Hypotheses 2: That the men receiving adjunctive SERM will have a significantly greater improvement in cognitive function than men receiving adjunctive placebo
Persistent neurocognitive deficits are a major cause of severe disability and impaired long-term psychosocial outcome in schizophrenia (SZ). In particular, within the auditory system, early deficits such as the behavioral and neurophysiological ability to match tones that vary in pitch correlate with impairments in auditory emotion recognition (affective prosody) and general functioning, suggesting that interventions aimed at remediating sensory-level dysfunction may lead to significant improvement in higher order cognitive/emotion processes. Efforts to ameliorate cognitive deficits in schizophrenia utilize either pharmacological agents or behavioral treatments such as cognitive remediation, which generally focus on higher order processes, and not on the early sensory processing which may be key to functioning. Numerous pharmacological agents have been proposed, but accumulating evidence suggests that dysfunction of the N-methyl-D-aspartic acid (NMDA) receptor may be one of the root causes of schizophrenia, including sensory and cognitive impairments, suggesting that an NMDA based treatment may be efficacious in reversing these deficits. D-Cycloserine, a synthetic partial NMDA agonist has been used in anxiety disorders to augment learning in cognitive remediation. Because of a tendency to act as an NMDA antagonist at higher doses D-cycloserine is not effective in schizophrenia. In contrast, D-serine (DSR), is a full agonist, and is therefore more ideal for enhancing NMDA function and cognitive remediation. While previous use of DSR was limited by safety concerns in rodents,the investigators have shown that it can safely be used at doses of 60 mg/kg and, moreover, demonstrates converging improvement in symptomatic, cognitive and sensory-based measures in schizophrenia. Evidence also suggests that NMDA receptor dysfunction in schizophrenia may be relative, rather than absolute, suggesting that the enhanced practice of a cognitive remediation paradigm might be able to overcome reduced plasticity and treat cognitive dysfunction. This project will be the first to combine the NMDA based and sensory-based cognitive remediation (SBR) approaches, and will utilize not only DSR, but also a tone matching SBR paradigm has been shown to enhance learning in healthy controls, as well as a paradigm designed to augment visual motion detection. This study will pilot these interventions in a double-blind, placebo-controlled, randomized crossover design that will use neurophysiology together with cognitive tests to explore the effects on brain activity and cognitive function in 16 patients with schizophrenia or schizoaffective disorder. The investigators hypothesize that DSR+SBR will lead to improvement. Subjects will have an initial visit to establish baseline performance on cognitive tasks before returning for 3 visits when they will receive blinded study medication [60 mg/kg of DSR (2 days) or placebo (1 day)] in a randomized order. The procedures on the treatment days will include the SBR paradigm and pre/post neurophysiological measurements. Primary outcomes are improvements in neurophysiologic and behavioral sensory processing. The main goal is to establish the preliminary efficacy to use in a follow-up multi-dose study utilizing a multiple session SBR R01 application.
This Phase I/IIa Proof-of-Concept (PoC) trial is designed to assess the effect of adding a single and repeated low dose (15mg/d) of pipamperone (PIP) for 6 weeks to stable treatment with an effective dose of risperidone (RIS) or paliperidone (PAL) on functional MRI tests and clinical outcome of chronic schizophrenic patients with residual, so-called 'positive' symptoms, as well as on cognition, motivation, subjective well-being of patients, negative symptoms, general psychopathological symptoms and safety/tolerability.
In this trial, researchers aim to investigate if prolonged-release melatonin can facilitate the withdrawal of chronic benzodiazepine administration in patients with schizophrenia. Furthermore, researchers will investigate the association of benzodiazepine dose reduction with the following clinically important variables: sleep, psychophysiology, cognition, social function, and quality of life.
