Filter by:This study proposes to adapt an evidence based peer parent navigator (PPN) intervention, called Parent Connectors, in which trained and supervised PPNs deliver weekly telephone-based support for six to nine months to parents or caregivers of all newly enrolled youth or young adults (Y/YA) in FEP services. This PPN model will be used to enhance the delivery of Coordinated Specialty Care (CSC) for Y/YA in New York's state program for FEP, called OnTrackNY (OTNY). This research project has potential to add value to the CSC model through the inclusion of a feasible, low burden intervention that may improve family participation in services and Y/YA outcomes. Using random assignment, this study will examine the feasibility and preliminary impact of an accelerator strategy-the inclusion of peer parent navigators or PPNs-in CSC teams.
A large proportion of people with a schizophrenia-spectrum disorder, especially in the early stages of the disease, regularly consume cannabis. Cannabis use is associated with poor prognostic outcome; however, there are no effective interventions targeted at reducing cannabis use or its deleterious effects in this population. The present trial is designed to test whether cannabidiol (CBD), a cannabinoid whose effects are in many ways antagonistic to those of Δ9-tetrahydrocannabinol (THC), can reduce psychiatric symptoms, cognitive deficits, and cannabis use in people with recent-onset psychosis who regularly consume cannabis.
Early intervention programs for psychosis help improve short-term treatment and recovery outcomes for individuals experiencing psychosis. OnTrackNY is a coordinated specialty care (CSC) program, developed to treat young adults within two years of experiencing a non-affective episode of psychosis. This project aims to expand the role of family engagement and support within the OnTrackNY model. Borrowing from the Needs Adapted and Open Dialogue models, the study team created a family therapy service that includes the client and members of his/her social network to navigate crises and assist in treatment planning. This service, Social Network Meetings, will be offered to individuals enrolled in the OnTrackNY@MHA program as an additional, voluntary, service option. The study proposes that the introduction of Social Network meetings may improve treatment and recovery outcomes.
Social cognition concerns the understanding of how people think about others and how that, in turn, influences our behavior, feelings, and social interactions. schizophrenia social-cognitive impairment is profound (effect size D>1.2), medication resistant and critically limits functional well-being . Social cognition involves complex patterns of coordinated activity within numerous cortical and subcortical networks, making it a difficult target for clinical neuroscience investigation. Yet, prior research demonstrates that sensory-perceptual dysfunction in schizophrenia can upwardly generalize into higher-order social-cognitive impairment making perception a tractable and fruitful approach for studying social cognition in schizophrenia. Here, the investigators explore how distortions in perception of temporal coincidence can contribute to the aberrant inferences of physical causation and social agency.
Cognitive deficits are some of the most prominent and disabling symptoms of schizophrenia. Evidence suggests that schizophrenia involves alterations to the functioning of a neural system under the control of a brain chemical called GABA. The present project will compare the effects of low-dose clonazepam (at a sub-sedating dose) to placebo, for effects on GABA- modulated brain activity measured by EEG, and associated cognitive processes in people who have schizophrenia.
The purpose of this study is to test the efficacy of transcranial direct current stimulation (tDCS) for the treatment of auditory hallucinations in patients currently on risperidone treatment who are experiencing recent onset psychosis.
The objectives of this 15-day study are: 1. To compare steady-state trough plasma concentrations of clozapine and its metabolite norclozapine when given once daily and twice daily (at the same total daily dose) 2. To determine if frequency of clozapine administration has an effect on: 1. Symptoms of schizophrenia 2. Adverse effects of clozapine 3. Fasting blood glucose, lipids, creatinine, and urea 4. Weight and waist circumference
The purpose of this 9-day study is to determine if: 1. Pantoprazole modifies the steady-state plasma concentrations of orally administered psychotropic medications including valproic acid, lithium, and second-generation antipsychotics (i.e., aripiprazole, asenapine, clozapine, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, ziprasidone) 2. Serum gastrin levels change within a week of starting or stopping pantoprazole
A ten week, blinded trial of vitamin D vs. placebo in 80 patients with schizophrenia or schizoaffective disorder who have low blood levels of vitamin D and elevated blood levels of the amino acid proline. The aims of the study are to evaluate an anticipated clinical response to vitamin D supplementation including negative symptoms and cognitive deficits, evaluate safety of vitamin D supplementation for schizophrenia patients and evaluate the relationship of changes in plasma proline levels and efficacy outcomes.
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.
