Filter by: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 is a two part study. Part A is a multiple-ascending dose study in up to 6 different groups of healthy subjects, with approximately 12 subjects in each of the groups. Part A will allow investigation of up to 6 different doses of LY2979165. The drug will be administered for a total of 14 days. Subjects will be resident in the clinical research unit (CRU) from Day -1 (the day before dosing) until Day 15. Part B will investigate a dose of LY2979165 previously administered in Part A in up to 12 subjects. The drug will be administered for a total of 14 days. In addition to the same assessments as would have been completed in Part A, subjects in Part B will also have cerebrospinal fluid samples taken from the lower lumbar region of their spine.
'Real life' retrospective patient cases (10) to provide an objective and robust analytical report of patient management and prescriptions behaviours for Schizophrenia, Bipolar disorders and Major depressive disorders.
The whole study will be divided into two major parts: (A) A 12-week, double-blind, randomized controlled, parallel n-3 fatty acids adjunctive therapy study in 30 bipolar disorder patients with mild to moderate depression. (B) A double-blind, randomized controlled, parallel n-3 fatty acid add-on prophylactic study in 31 patients with stable bipolar disorder.
Bipolar disorder is a severe, chronic and recurrent illness, that affects nearly the 5% of the population. Recent research point at the relevance and persistence of cognitive dysfunctions in bipolar patients even beyond the acute phases, although cognitive impairment has been classically associated with schizophrenia and not bipolar disorder. Current findings suggest that some intervention is needed in order to improve not only affective symptoms but also cognitive dysfunctions, so that patients could benefit from cognitive remediation techniques to improve cognitive impairment and the functional outcome. There is no previous research on the efficacy of cognitive remediation programs on bipolar disorder.
The aim of this trial is to evaluate the effectiveness of the Illness Management and Recovery program for people diagnosed with schizophrenia or bipolar disorder in according to their level of functioning.
This study will investigate the safety and tolerability of a flexible dosing regimen of asenapine for the long-term treatment of manic or mixed episodes associated with bipolar disorder I in children and adolescents who completed study P06107.
Obtain phenotypic data and a DNA/blood sample from mood disorder patients undergoing pioglitazone or quetiapine XR treatment as a part of an IRB approved clinical trial conducted at the Mood Disorders Program. Pioglitazone treatment is examined in metabolic syndrome comorbid with bipolar depression (IRB # 07-08-24) and unipolar depression (IRB # 07-07-20). Quetiapine XR treatment is examined in generalized anxiety disorder comorbid with bipolar depression (IRB # 10-06-19) and unipolar depression (IRB # 12-01-29). Please refer to the respective IRB protocols for more information.
The purpose of this observational study is to study specific outcomes of interest in users of quetiapine compared with all other atypical antipsychotics and specifically olanzapine and risperidone. The outcomes of interest are all-cause mortality, failed suicide attempts, extrapyramidal symptoms, diabetes mellitus, hypothyroidism, acute myocardial infarction and stroke. This retrospective cohort study is based on population-based record linkage system (PHARMO RLS) capturing about 2.5 millions residents in the Netherlands.
This study aims to investigate the potential for Transcranial Direct Current Stimulation (tDCS) to enhance cognitive functioning in euthymic bipolar patients through comparing the effect of active or sham tDCS (placebo control) during the performance of two cognitive tasks. The investigators hypothesize that task performance will be improved with active relative to sham tDCS.
