Active clinical trials for "Psychotic Disorders"

Women represent the fastest growing population within the VHA. Many are of reproductive age and experience mental health concerns. Women with mental illness are at greater risk for unplanned pregnancy and poor pregnancy outcomes due to factors related to mental health and mental health treatment. Similarly, mental health concerns (e.g., impact of pregnancy on mental illness, psychiatric medications and pregnancy) can affect reproductive life goals and plans. Reproductive life planning (RLP) interventions that include considerations and concerns women Veterans with mental illness face are needed. The investigators adapted existing RLP materials to create an interactive, individualized, client-centered RLP intervention designed to help women Veterans with mental illness develop a mental health-informed reproductive life plan and reproductive life goals (RLP-MH). The current study aims to determine if the RLP-MH intervention is feasible and acceptable to women Veterans and if it increases engagement in behaviors to address RLP goals.

This study aims to examine the effectiveness of cognitive behavior therapy for psychosis in first episode patients and see the outcome of CBT on psychotic symptoms. Because cognitive behavior therapy mostly use in depressive patient to treat the negative thinking pattern Cognitive behavioral approaches in the treatment of psychosis have become more prevalent in recent years for a number of reasons. Evidence has been available for the past two or three decades regarding the success of these techniques with other forms of psychopathology such as depression, anxiety disorders, and medical problems. Anxiety, depression and low self-esteem have been cited as the most common consequences of psychotic disorders. The observation has also emerged that many patients develop their own coping strategies for reducing the frequency, severity, and disruptiveness of their symptoms. There has also been increasing evidence regarding the influence of social environmental factors on the course of psychosis and the development of stress-vulnerability models to explain these relationships. Research suggests that 20 to 50 percent of persons with psychosis who receive neuroleptics continue to experience difficulties related to their psychotic symptoms.

Clozapine has been demonstrated to be clinically superior to other antipsychotics in treatment-resistant schizophrenia (TRS), and is positioned as such in treatment guidelines. Because it is relegated to use in TRS, guidelines require that it only be used after other antipsychotics have failed; accordingly, clinicians routinely contend with stopping the previous antipsychotic in making the switch to clozapine. Perhaps because of its numerous and potentially severe side effects, the issue of clozapine titration has frequently been addressed, although to our knowledge no study has, as of yet, assessed the comparability of gradual vs. immediate antipsychotic discontinuation in switching to clozapine. To address the gap in knowledge specific to clozapine, the investigators conducted a pilot, 8-week, double-blind, randomized controlled trial examining immediate vs. gradual antipsychotic discontinuation in patients with schizophrenia undergoing a switch to clozapine.

This study will investigate the efficacy and safety of RO6889450 as monotherapy in participants experiencing an acute exacerbation of symptoms of schizophrenia or schizoaffective disorder.

For the present study, Investigators will examine the efficacy of active prefrontal anodal tDCS versus placebo (sham) interventions to treat WM dysfunction in schizophrenia. Investigators selected the prefrontal stimulation modality that proved most effective in enhancing high-load WM performance in single dose stimulation in healthy participants . The study employs a multi-stimulation approach, with 2 sessions per day for 5 consecutive days in the active treatment group (n=15) compared to a group that receives only sham stimulation (n=15). This preliminary approach is based upon findings of a recent study applying cathodal tDCS stimulation over left temporoparietal cortex (with left prefrontal anodal stimulation) for the treatment of persistent auditory hallucinations in schizophrenia. In a a recent study clinical benefits were maintained for at least 3 months following stimulation. In the present study, in addition to clinical outcome, researchers will evaluate whether similar improvement can be obtained with WM, EEG activity, and functional outcome (e.g., discharged from hospitalization following significant improvement or remission).

Social functioning deficits are among the most disabling and difficult to treat aspects of schizophrenia. An essential component of social functioning is metacognition-a process that is profoundly disrupted in schizophrenia and represents the ability to reflect upon the mental states of oneself and others. To date, treatment efforts in schizophrenia have been hindered by barriers in accurately monitoring client's real-world social interactions. Recently, wearable technologies have evolved to provide therapists with innovative, ecologically-valid tools. The Electronically Activated Recorder is a wearable audio recorder that collects behavioral samples at pre-programmed intervals; it holds great promise as a method for yielding concrete, real-world examples of social interactions that can be used by therapists in session to enhance metacognition. Despite the immense costs of social functioning deficits, no previous studies have investigated whether functioning can be improved by integrating wearable audio recorders with psychosocial interventions. By enhancing therapy using a wearable recording device, this proposal's primary goal is to implement a novel intervention that targets metacognitive deficits to improve social functioning. The novel intervention will be tailored to individual clients-based on the content of recorded social interactions-in a way that is not possible using traditional psychotherapy. This will allow clients and therapists to step out of the therapy room by offering a window into how clients process material in real-world interactions. In this study, a randomized controlled trial will be conducted with two schizophrenia groups receiving six months of individualized: 1) Metacognition Reflection and Insight Therapy (MERIT) alone (Standard MERIT); and 2) Tailored MERIT using wearable audio recorders. In this study, our specific aims will test feasibility, effectiveness, and acceptability of Tailored MERIT.

In this study, the investigators will be examining the effects of repetitive transcranial magnetic stimulation (rTMS) and intermittent theta burst stimulation (iTBS) on social cognitive impairments in individuals with schizophrenia spectrum disorders. Participants will be chosen by chance to receive either active rTMS stimulation, active iTBS stimulation, sham rTMS, or sham iTBS. The investigators predict that active 10Hz and iTBS stimulation will improve social cognitive impairments compared to sham stimulation. We aim to identify which type of active stimulation is most effective at inducing changes social cognition brain circuitry and secondarily which type of active stimulation is best tolerated and most effective at inducing changes in social cognitive performance.

Purpose: To test the effectiveness of an exercise intervention that combines group walking, activity tracking, and heart rate monitoring (i.e. Physical Activity can Enhance Life, PACE-Life) on the physical and mental health for individuals with schizophrenia spectrum disorder. Participants: 50 individuals with schizophrenia spectrum disorders. Procedures (methods): During the baseline assessment, which can be completed virtually and in-person (based on participant preference) all participants will be provided with a Fitbit wristband and instructed how to use it. During the first group session, participants will be taught how to use their heart rate (on the Fitbit) to determine how fast participants should walk (to achieve the appropriate exercise dosage). Information on proper care, usage, and how to determine the appropriate heart rate from the watch, to guide the intensity of the walk, will be provided to participants and reviewed at each group session. Participants randomly assigned to the PACE Life virtual walking group sessions will meet the other group members and group leaders and be reminded of the heart rate (HR) that corresponds with the intensity of that group session. Next, the group will exercise for 15 minutes in the first two weeks, progressing to 30-minute walking sessions over the course of the intervention. At the completion of the sessions, everyone will take a break for water and review the walk. After the second group session of each week, participants will receive weekly progress reports of their steps and minutes spent walking the prior week (obtained from Fitbit devices). During this session, participants will also set individual goals for the upcoming week for both their "intensity walks" and total steps per day. Participants randomly assigned to Fitbit Alone will be given a Fitbit and shown how to use it by study staff. Participants will also be given information on current recommended physical activity guidelines (150 min/week of moderate intensity exercise) and will be told that study staff may be contacting them on a weekly basis (or shorter, if necessary) if it looks like participants are not wearing their Fitbit for a certain number of days (e.g. 3 consecutive days) or to troubleshoot any issues. If necessary, participants might be invited to meet with research staff to get assistance on any Fitibit or exercise-related issues.

The acute phase of this study will monitor the response to a combination of an atypical antipsychotic medication olanzapine with an antidepressant medication sertraline in the acute treatment of the disorder. It is predicted that this combination will improve symptoms of psychotic depression and be associated metabolic side effects. Factors that moderate tolerability will be monitored. Improvement in symptoms could take between 4 and 12 weeks, followed by a period of 8 weeks during which participants will continue to take the same medications to stabilize the remission from symptoms of psychotic depression. The maintenance phase will be a randomized, double-blind, placebo-controlled study of olanzapine for a period of up to 36 weeks to test whether continuing this combination decreases the risk of relapse and whether discontinuing the combination leads to improvement in metabolic measures. Subjects who complete the acute phase will be asked to consent separately to the randomized maintenance phase.

Supplementation of Vitamin D in those with low levels will increase the level and result in some improvement in health and psychopathology measures.
