Filter by:The purpose of this study is to establish pharmacodynamics (PD), pharmacokinetics (PK), and adverse event (AE) profile of OPC-34712 administered to schizophrenic/schizoaffective subjects. The goals of this trial are three-fold: - To determine the effect of OPC-34712 on the individual QT interval (QTcI) corrected for placebo - To determine the effect of moxifloxacin on QTcI - To examine the concentration-effect relationship of OPC-34712 and moxifloxacin on QTcI
This project tests a model for improving illness self-management among persons who have both serious mental illness and diabetes and will be performed within a primary care setting at a safety net hospital system. The information gained from the randomized trial will be supplemented with reports from participants about their experiences of trying to improve illness self-management. Improvements in self-management should result in a reduction of psychiatric symptoms and improvements in functioning and physical health.
The project is a 15-year follow-up of 240 young adults whose families participated in an experimental evaluation of the New Beginnings Program (NBP), a preventive intervention for divorced families. The NBP was provided in late childhood; the follow-up occurred in young adulthood. Families were randomly assigned to one of three conditions: mother program (MP), dual-component mother and child program (MPCP), or literature-control (LC) condition. Programs were designed to change several putative mediators of children's post-divorce mental health problems using empirically-supported change strategies. The investigators expected that the NBP would have either main or risk by program interactive effects on mental health and substance use problems and disorders, developmental tasks, parent-young adult relationships, physical health problems, and competencies, such that YAs who participated in NBP will have better functioning than YAs in the control condition. The investigators expected that the NBP will have either main or risk by program interactive effects on mothers' mental health; those in the NBP are expected to have fewer mental health problems than those in the control condition.
The investigators hypothesize that sustained-release DMXB-A-SR (3-2,4 dimethoxybenzylidene anabaseine sustained release) will provide clinical improvement in cognition in patients with schizophrenia who are smokers and who are non-smokers. The study drug may also maintain abstinence from cigarette smoking and improve other symptoms in patients with schizophrenia.
The investigators propose to recruit patients who have experienced a recent first episode of psychosis who have a chart diagnosis of Schizophrenia, Schizophrenifom, Schizoaffective Disorder, Psychosis NOS, or Bipolar I Disorder with psychotic features and self identify themselves as a current cigarette smoker. Aiding this population with smoking cessation is crucial as the majority of people with schizophrenia spectrum disorders (50-90%) smoke, which is leading to early mortality. While these individuals can benefit from standard evidence-based treatment, these treatments are underutilized. Web based programs, such as the EDSS and thetruth.com, can provide education and motivational tools to help people with a recent onset of psychosis use evidence-based smoking cessation treatments. This study aims to test these two web-based programs among young people with a recent episode of psychosis for usability and likeability and to explore whether use of these two programs will motivate users to seek smoking cessation treatment or to engage in other quitting behaviors in the month following use of the programs. Information gathered from this proposal will be used to help the researchers decide whether either of these two programs will be reasonable to include in a larger study of a comprehensive treatment for individuals with first episode psychosis.
Purpose: Test whether intranasal administration of the neuropeptide, oxytocin, improves social cognition, psychotic symptoms and social functioning in schizophrenia. Participants: 80 adults with schizophrenia or schizoaffective disorder for at least one year. Procedures (methods): Oxytocin or placebo will be administered twice daily in an intranasal spray for 12 weeks. Before, during and at the end of the trial, each subject will undergo psychiatric symptom ratings and tests of mental abilities used in social functioning, cognition, and social competence.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of two doses (12.5 and 50 mg) of NBI-98854 administered once daily (q.d.) for the treatment of tardive dyskinesia in subjects with schizophrenia or schizoaffective disorder.
The aim of this study is to determine whether blood levels of lithium or sertraline are affected by different phases of the menstrual cycle and whether there is an effect on psychiatric symptoms. Subjects are seen for two visits: one visit during the luteal phase and one visit during the follicular phase of the menstrual cycle. On each visit, they will fill out a depression, anxiety and mania rating scale. Also at each visit a 20mL blood sample will be drawn to measure progesterone level and either a lithium or sertraline level, depending on which medication the patient takes. The primary hypothesis in this study is that blood levels of lithium and sertraline will be significantly lower in women during the luteal phase of the menstrual cycle than during the follicular phase. Examination will also be made of whether symptoms will increase in severity during the luteal phase as compared to the follicular phase. The investigators expect a negative linear association between symptom severity and blood level, i.e. expect symptom severity to worsen as blood levels of lithium or sertraline decrease.
The overall goal of this project is to identify intermediate phenotypes for psychosis across the schizophrenia and bipolar disorders boundary with implications for future genetic studies. Recent studies provide considerable evidence that schizophrenia and psychotic bipolar disorder may share overlapping etiologic determinants. Identifying disease-related genetic effects is a major focus in schizophrenia and bipolar research, with enormous implications for diagnosis and treatment for these two disorders. Efforts have been multifaceted, with the ultimate goal of describing causal paths from specific genetic variants, to changes in neuronal functioning, to altered brain anatomy, to behavioral and functional impairments. Parallel efforts have identified and refined several alternative endophenotypes that are stable, heritable, have (partly) known biological substrates, and are associated with psychosis liability. Although many such endophenotypes have been individually studied in schizophrenia, and to a lesser extent in bipolar disorder, no study has comprehensively assessed a broad panel of these markers in the two disorders with parallel recruitment, and the extent to which they mark independent aspects of psychosis risk, or their overlap in the two disorders. In this research project, we will examine a broad panel of putative endophenotypes in affected individuals and their first degree, biological relatives in order to: 1) characterize the degree of familial phenotypic overlap between schizophrenia and psychotic bipolar disorders; 2) identify patterns of endophenotypes unique to the two disorders; and, 3) contrast the heritability of endophenotypes across the disorders. We will obtain measures of neurophysiology (e.g., eye tracking, P50 gating, PPI, and P300), neurocognition (e.g., attention/vigilance, episodic and working memory), and brain structure (e.g., volumes of gray and white matter in specified brain regions). Blood samples will also be collected and stored for formal DNA linkage analyses using the independent phenotypes identified above. All volunteers will also be given the option to donate dermal biopsies for future research studies. Establishing similarities and differences in the endophenotypic signatures within schizophrenia and bipolar families will provide important insights for future genetic studies, and clarify concepts about common and distinct aspects of pathophysiology, potentially meaningful heterogeneity with disorders, and the clinical boundaries of the two most common psychotic disorders in adult psychiatry. This line of investigation will potentially impact our conceptualization of psychotic disorders, help us make critical strides to identify the pathophysiology of psychosis, and guide development of new specific treatments targeting particular deficits.
This will be a double blind, randomised, placebo controlled, cross over study in which up to 20 otherwise healthy male nicotine abstinent smokers will be tested following 3 acute treatment conditions (placebo, 4 and 8mg of GSK1034702). Each subject will undergo screening assessments within 30 days prior to administration of the first dose of study medication. There will be 3 treatment sessions and dosing will be separated by a minimum 1 week washout period. There will be two testing days (day 1 and day 2) per treatment session. On each treatment session subjects will be admitted on day 1. On day 1, subjects will be administered placebo and approximately 3 hours later, there will be a Baseline EEG/ERP recording, neuropsychological (Cogstate battery) testing and mood/craving/dependence questionnaire assessments . Subjects will be allowed to smoke until approximately midnight on day 1. On day 2, subjects will undergo a pre-drug neuropsychological (Cogstate battery) testing and questionnaire assessments of mood/craving. This will be conducted approximately 1 hour prior to dosing. Subjects will be randomized to one of six treatment sequences. Post dose EEG/ERP recording, neuropsychological (Cogstate battery) testing and mood/craving measurements will be conducted between 3 and 6 hours post treatment to coincide with peak pharmacokinetic effects. This testing will be performed approximately at 12pm following at least 12hrs of nicotine abstinence. Blood samples will be collected at baseline (pre-drug) and following drug administration to quantify exposure levels.
