Filter by:Purpose and objective Schizophrenia is a chronic debilitating illness with cognitive deficits that cause serious impairment in psychosocial recovery and with few treatments to remediate these deficits. One area that holds great promise for the development of novel, effective therapies is noninvasive brain stimulation. The investigators have used one form of brain stimulation, transcranial magnetic stimulation (TMS), for some time to modulate and enhance cognitive function in the brain, especially working memory (WM) function, which has a central role in most executive processing that occurs in the brain. Theta burst stimulation (TBS) is a paradigm of TMS which has been shown to effectively modulate WM. Moreover, TBS can modulate gamma neural oscillations in the brain and neural activity, both of which have been implicated in the physiology of WM and pathophysiology of the disease process in schizophrenia, making these measures highly valuable for assessing physiological effects of TBS on cognition, quality of life and cortical inhibition. The purpose of this study is to evaluate the effect of TBS on WM in patients with schizophrenia, to develop evidence for potential brain stimulation techniques to treat cognitive deficits in schizophrenia. Study activities and population group: Study subjects will be inpatient schizophrenic individuals with minimal positive symptoms and predominant cognitive deficits at Duke University Hospital. In an initial session they will be screened and taught a WM task. Following this, one TBS session will follow in which TBS will target dorsolateral prefrontal cortex. They will perform the WM task before, with and after the TBS, with an expected pre-post enhancement of WM performance. Implications - There is a great need for treatments for cognitive deficits in schizophrenia. The results of this study will serve to generate pilot data for a much larger grant to develop a TBS therapy for remediating such cognitive deficits.
The present work aims to develop a randomized clinical trial with a sample of 165 patients diagnosed with an emotional disorder. All participants are tested by several self-reports related to common mental disorders in a repeated measures design, pre and post treatment as well as a six month follow up. We think this study will demonstrate that brief psychological treatments should be prioritized over pharmacological treatment for such pathologies in the Primary or Secondary Care context to improve the patient´s quality of life while simultaneously reducing costs.
The project aims to test the utility of implementing a mobile health application ("mhealth app") in early psychosis care in the community outpatient setting and in the university medical center setting. We will enroll 60 individuals in the early stages of psychotic illness who are receiving care in two UC Davis affiliated community based early psychosis outpatient programs: the Aldea Child and Family Services SOAR Programs in Napa and Solano Counties (Napa SOAR, and Solano SOAR), as well as the UC Davis Early Psychosis Programs (EDAPT and SacEDAPT clinics). Early psychosis (EP) participants will include individuals at high risk for developing a psychotic illness (termed "clinical high risk" or CHR) and individuals within two years of their first psychotic episode (termed "first episode psychosis" or FEP). Over the course of five months, EP participants will use the app on their mobile device to complete daily surveys assessing mood, social interactions and medication adherence, and weekly surveys assessing clinical symptoms, sleep and medication adherence. EP participants will also complete clinical assessments with UC Davis research staff at the initial and final study appointments (baseline and five month timepoints). Clinicians working in the three early psychosis programs will also participate in the study. In their clinical role, they will interact with EP participants' app data via the Dashboard, a secure web-based portal, and provide feedback on the clinical utility of the data that is provided on the dashboard. EP participants and their clinicians will also provide feedback on the impact of the app on the therapeutic relationship.
The study is a combined health services research study and a clinical patient outcomes sub-study. The aims of the study are to give new knowledge on (RQ1) current implementation in mental health services of four evidence based practices for treatment of psychoses, (RQ2) how and to what degree implementation support affects the implementation, and (RQ3) whether improved implementation is associated with better clinical course and higher patient satisfaction. Pairwise randomized study in six health trusts on implementation of the four evidence based practices physical health care, antipsychotic medication, family psychoeducation, and illness management and recovery. Data on model fidelity and patient course/experience are collected at baseline and after 6, 12 and 18 months. 39 clinical units (CMHCs/departments) choose two practices and receive implementation support on one for 18 months after randomization. RQ1 is answered from baseline data, and RQ2 and RQ3 from data after 6-18 months.
In this study, an APA program by web (e-APA) will be offered to two groups of participants (21 patients and 21 healthy volunteers (HV)) in remote video (use of the SAPATIC (Santé Activités Physiques Adaptées utilisant les Technologies de l'Information et de la Communication) platform developed by the company V@SI). At the same time, two control groups, a group of 21 patients and a group of 21 HV will undergo an health education program (HE) through the collaborative SAPATIC health platform of V@Si and will constitute the control groups. The content of the APA sessions will be administered by V@Si. This program offers content aimed to improve aerobic capacity and muscular strength while relying on the motivation of the participants
Cognitive-behavioral therapy (CBT) and social skills training (SST) are recommended psychological interventions to improve symptomatology and functional recovery in psychosis. In addition, CBT may reduce hyperactivation of the brain structures responsible for the stress response. In patients with early onset psychotic disorder (EOP) there are not any previous controlled study that has analyzed the efficacy of this type of intervention. The aim of this study is to investigate efficacy of CBT + SST in symptomatic and functional improvement after the treatment in patients with EOP. The study will also examine the potential effect of the intervention on neurobiological stress markers.
A burgeoning body of research has pointed to increased efficacy of clozapine (CLZ) over other antipsychotics in schizophrenia (SCZ). On the other hand, safety concerns likely cause underutilization across a range of European and other nations. The lack of data available to predict efficacy and adverse drug reactions (ADRs) of CLZ further contributes to underprescription rates in these countries. Here, we hypothesize that (epi)genetic and non-genetic factors aid to help predict treatment outcome (efficacy + ADRs) to CLZ. We furthermore posit that such prediction will result in enhanced quality of life of both patients and family members. Our primary objective is to predict CLZ treatment outcome based on phenotypic and genetic data obtained through the current design. The first secondary objective is to investigate which methylation levels/patterns are correlated with CLZ treatment outcome. The second secondary objective is to aid in the further elucidation of the genetic architecture of SCZ and any possible differences between 'regular' SCZ patients and those on CLZ, who are generally more severely ill. We thus intend to cover two currently unmet needs using a precision medicine approach: the lack of knowledge about determinants of treatment response to CLZ and the lack of insight into neurobiological differences between 'regular' SCZ and relatively treatment resistant subjects (CLZ users). The prime analysis will be a common variant hypothesis-generating genotyping endeavor investigating treatment response to CLZ. Additional analyses include whole-genome methylation and gene expression analyses and analyses of non-genetic determinants of response. We will include 2,500 CLZ treated patients for our discovery cohort, which is in line with previous whole-genome pharmacogenomics studies and our power calculations. We will replicate any genome-wide loci using our prospectively collected cohort of new users (N=59). Potential yields include a publicly available prediction tool to help identify patients responsive to CLZ in early disease stages and prevent harmful effects. In addition, common variant analyses compounded by pathway analyses may help elucidate the mechanisms of action of CLZ. We ask for broad informed consent from participants ensuring rich, longitudinal phenotypic and genotypic data resources for both currently planned and future analyses, allowing e.g. next-generation sequencing focused on both CLZ and SCZ disease genetics (e.g. in large consortia). We plan to also generate polygenic risk scores (PRS) of CLZ efficacy and use those to identify other diseases or patients for which CLZ may be helpful, e.g. schizoaffective disorder patients who are sometimes first treated with mood stabilizers. Last, evidence hints that disparaging genetic loci influence efficacy to different antipsychotics. Adding genetic data from our cohort to existing datasets of response to other antipsychotics may help identify such loci. Finally, comparison studies with non-CLZ using patients suffering from SCZ may deepen the understanding of biological mechanisms underlying treatment resistance (or: a relatively severe course of illness).The results of this genetic part of the study will be combined with the results from our other research protocol 'Phenomics and genomic of clozapine pharmacotherapy - New Users'.The overarching goal of both projects is to create a prediction model for clozapine outcome (response (and side effects). This model includes genetic, epigenetic and clinical data.
A 2-year prospective observational study comparing a group of patients in remitted states of psychosis undergoing guided antipsychotic dose reduction to a similar group of patients under maintenance antipsychotic treatment with the main outcome of interest that if the rates of relapse of psychosis between these two groups will be different.
This randomized clinical trial compares the influence of joint crisis plans (JCP) or crisis cards to reduce psychiatric coercion for people with severe and often recurring mental illnesses like schizophrenia, bipolar disorder or schizoaffective disorder. Both interventions will be carried out as an integrated part of otherwise standard psychiatric in-patient and out-patient care in psychiatric units specializing in the acute or non-acute treatment of mentioned mental illnesses.
An acute psychotic episode is a severe psychiatric syndrome which might occur in different psychiatric diagnoses. The outcome prediction of relapse rate of a psychotic episode within a certain time frame is difficult and depends on many factors. More and better predictors are required to improve the outcome prediction in order to adjust therapy and follow-up if patients suffer from this acute disease. Copeptin, a surrogate marker for vasopressin, has been proven helpful in the prediction of the outcome in serious somatic diseases. Additionally, a rise of copeptin due to psychological stress was shown. The aim of this study is to investigate the association of the neuroendocrine biomarker copeptin and the prediction of the onset of psychotic episode within one year.
