Filter by:The purpose of this study is to evaluate the pharmacokinetics of aripiprazole in subjects with Bipolar 1 Disorder or Schizophrenia who have a history of suboptimal aderence and are currently on treatment with oral aripiprazole.
The primary objective of this study is to determine whether aspirin is effective in alleviating symptoms of the clinical high risk (CHR) syndrome for psychosis. The investigators further aim to determine whether it may delay or prevent the onset of psychosis in those currently experiencing CHR symptoms. As secondary measures the investigators aim to collect laboratory studies of inflammation markers and genetic samples to determine whether certain genetic profiles correlate with risk for psychosis, or response to aspirin treatment.
Improvement of clinical long-term outcome through the implementation of early detection and intervention within a specialized network of integrated care (ACT and hometreatment) for adolescents and young adults with a first episode of psychosis between 12 and 29 years.
This study will evaluate the safety and efficacy of pimavanserin 40 mg compared to placebo in patients with Alzheimer's disease psychosis.
Randomized, double-blind clinical trial of tocilizumab vs. placebo as add-on treatment for residual positive, negative, and cognitive symptoms in schizophrenia. The primary study hypothesis is that individuals receiving tocilizumab will show greater improvements in their PANSS total scores than those taking placebo.
The early stages of schizophrenia are associated with significant decreases in social and intellectual abilities, with more declines in chronic disease. Studies have identified relationships between duration of untreated psychosis (the duration between the onset of positive symptoms and treatment) and worse long term outcomes. However, the neurobiology of this phenomenon and its implications for response to antipsychotic medications remain poorly understood. Glutamatergic excess altering brain connectivity might provide an explanation for why those with longer duration of untreated psychosis have worse clinical outcomes. The investigators propose to use neuroimaging to study 67 first episode psychosis subjects before and after sixteen weeks of treatment with risperidone, a common antipsychotic. We will measure (1) glutamate and (2) structural and functional brain connectivity and test the hypotheses that glutamatergic abnormalities are present in first episode patients and that longer duration of untreated psychosis is associated with greater connectivity abnormalities that set the stage for poor response to treatment. 67 demographic-matched controls will also be recruited as a comparison group - healthy controls will not receive antipsychotic medication. The investigator's previous studies have made progress in the understanding of abnormalities in the glutamate system and brain connectivity in unmedicated patients with schizophrenia and modulation of these by antipsychotic medication. Two indices of glutamatergic dysfunction have been identified. While antipsychotic medications appear to modulate glutamate, the disturbance in the relationship between metabolites is not restored with treatment. In addition, the investigators found that both structural and functional connectivity abnormalities in unmedicated patients with schizophrenia predict patients' response to treatment. To the investigator's knowledge, no other group has performed a study that uses a combination of complementary neuroimaging techniques that will allow generating a broad characterization of glutamatergic function and brain connectivity in first episode psychosis and change with treatment. The results of the proposed studies could suggest a mechanism by which the duration of untreated psychosis is associated with poor treatment response which might lead to new interventions to target the illness.
This study will identify and evaluate relevant biomarkers and structural brain imaging for understanding potential biological illness related mechanisms in medication-naïve subjects with early psychosis before and after initiation of antipsychotic medication
As specified in the VA Uniform Services Handbook, Family Psycho-Education (FPE) treatment must be available to all Veterans with schizophrenia who could benefit, and their family members. This includes those receiving care at Community Based Outpatient Clinics (CBOCs), and at Psychosocial Rehabilitation and Recovery Centers (PRRCs), whether provided on site, by referral, or by telemental health. However, less than 5% of VA medical centers offer FPE. Clearly, a major challenge is to devise ways to deliver mental health treatments and services to Veterans who need them in ways that meet their needs and preferences. The proposed project will compare the use of a website to deliver FPE to that of in-person delivered FPE. The findings could have profound implications for the VA's ability to improve the reach, use, appeal, and effectiveness of FPE for Veterans with schizophrenia, by using an e-health model that facilitates family involvement.
The aim of this study is to investigate whether sodium benzoate is superior to placebo in decreasing symptoms among patients with attenuated/transient psychosis. A total of 140 patients will be randomized in 1:1 ratio to receive sodium benzoate 1 g/day or placebo for 12 weeks. Concerning statistical power, the number of patients is sufficient to obtain statistical significance for a clinically meaningful effect size of 0.40 (Cohen's d). The primary outcome measure is change in PANSS sum score of delusions, hallucinations, suspiciousness and conceptual disorganization (the PANSS items that are inclusion criteria) at week 12. Change in CGI score at week 12 is the other primary outcome measure. The secondary outcome measures are change in PANSS total score at week 12, CGI score at week 24, and GAF at weeks 12 and 24.
The purpose of this study is to find the incidence of mental disorders during different periods of pregnancy and its associated factors and consequences.
