Cognitive Strategies in Early Psychosis 2

The goal of this clinical trial is to learn more about decision making in psychosis spectrum disorders, like schizophrenia. Participants will be people who have had symptoms of a psychosis spectrum disorder start within the last five years. The investigators will study how two study agents change decision making in people with psychosis, by asking participants to complete some brain games on the computer before and after taking the study agents. The investigators hope to improve our understanding of psychosis to help people in the future. The main research questions are: * Does a single dose of modafinil change how people with psychosis play the brain games? * Does a single dose of d-serine change how people with psychosis play the brain games? * Does a single dose of modafinil change brain activity? * Does a single dose of d-serine change brain activity? Participants will: * Complete an interview and self-report questionnaires. * Complete safety screening activities, like a blood draw, a urine drug test, and an alcohol breathalyzer test. * Complete functional Magnetic Resonance Imaging (fMRI) scans. fMRI uses magnets to take pictures of the brain. There will be six scanning appointments in the study, with two scans each. Appointments will be about a month apart. * Take a single dose of a study agent during each scanning appointment. The study agent will be taken after the first fMRI. There are three study agents in total: modafinil, d-serine, and a placebo. Each participant will take each study agent twice during the study. * Play brain games on a computer that measure decision making, thinking, and problem solving skills

Cerebellar Modulation of Cognition in Psychosis

The goal of this clinical trial is to learn about cognition in psychotic disorders (schizophrenia, bipolar disorder, and schizoaffective disorder). The main question it aims to answer is: Can we use magnetic stimulation to change processing speed (how quickly people can solve challenging tasks). Participants will be asked to perform cognitive tasks (problem-solving) and undergo brain scans before and after transcranial magnetic stimulation (TMS). TMS is a way to non-invasively change brain activity. Forms of TMS are FDA-approved to treat depression and obsessive compulsive disorder. In this study, we will use a different form of TMS to temporarily change brain activity to observe how that changes speed in problem-solving.

Decision-Making in Schizophrenia: A Combined Neuroimaging and Experience Sampling Study

The goal of this clinical trial is to learn if attention and ways of thinking impact decision-making and brain processes related to decision-making in people with schizophrenia or schizoaffective disorder relative to people without either condition. It will also learn how brain functioning during decision-making relates to real-world decisions made during daily life. The main questions it aims to answer are: * Does paying attention to specific information impact decision-making and brain processes? * Does thinking in a certain way according to specific 'thinking strategies' improve brain processes related to decision-making? * Does brain functioning during decision-making relate to real-world choices to engage in activities? Researchers will compare brain functioning and decision-making on computer tasks of gambling after participants have been trained to use a positive thinking strategy. They will compare what is different in the brain and behavior when participants use this strategy and when they do not. Participants will also answer brief surveys about activities and feelings for a week in their daily lives. Participants will: * Complete several hours of clinical interviewing, cognitive tests, and surveys of about symptoms, experiences, and personality * Complete computer tasks about gambling decisions during MRI brain scanning and while having their visual attention measured using eye-tracking * Complete brief surveys about their activities and feelings 5 times a day for 1 week using a cell phone. Each survey only take several minutes.

Biomarkers/Biotypes, Course of Early Psychosis and Specialty Services

The Biomarkers/Biotypes, Course of Early Psychosis and Specialty Services (BICEPS) study aims to understand the early stages of psychotic disorders like Schizophrenia, Schizoaffective Disorder, and Bipolar I Disorder. It involves gathering mental health information, brain scans (MRI), eye movement patterns (Eye-Tracking), and brain electrical waves (EEG) data from individuals who have experienced these disorders in recent years. Participants will be involved for about a year, with four visits over this period. Screening procedures, lasting approximately 3 hours, include tests for drug use, a pregnancy test for eligible women, clinical interviews about feelings and experiences, psychiatric and family history interviews, and a medical history review. Research procedures for eligible participants include DNA collection, a neuropsychological test battery, EEG, eye-tracking, and MRI. These procedures will help researchers understand brain function, genetics, and cognitive abilities related to psychotic disorders. Follow-up visits at 1-month, 6-month, and 12-month intervals involve modified clinical interviews and repeating neuropsychological tests to track changes over time. Participants may opt to provide DNA samples for genetic analysis, undergo various cognitive tests, EEG to record brain waves, eye-tracking to monitor eye movements, and MRI scans to visualize brain structure. Follow-up visits at regular intervals will help researchers track changes in symptoms and cognitive function. This study provides comprehensive insight into the onset and progression of psychotic disorders and offers valuable information for patients, families, and healthcare providers involved in managing these conditions. Our goal is to better understand whether a combination of biological markers and different types of people (BT1, BT2, BT3) can help us predict how well individuals with early psychosis respond to specialized care. We expect that those in BT3 will have the best outcomes, BT2 will have intermediate outcomes, and BT1 will have the poorest outcomes. Even though BT1 and BT2 might start with similar cognitive issues, their biology might lead to different responses to treatment. This research can help us understand which treatments work best for different people with early psychosis.

LRFN5 and OLFM4 in Schizoaffective Disorder

Schizoaffective disorder (SAD) is a chronic psychiatric condition characterized by psychotic and mood symptoms. Emerging evidence suggests that Leucine-Rich Repeat and Fibronectin Type-III Domain-Containing Protein 5 (LRFN5) and olfactomedin-4 (OLFM4) may play roles in synaptic organization, neurodevelopment, and neuroinflammation. However, no prior study has investigated these biomarkers in SAD. This cross-sectional case-control study aims to compare peripheral serum levels of LRFN5 and OLFM4 in subjects diagnosed with SAD in remission and healthy control subjects. The study also assessed associations between these biomarkers and clinical symptom severity, global functioning, and systemic inflammation measured by the Aggregate Index of Systemic Inflammation (AISI). The study aimed to investigate convergent synaptic and immunoinflammatory dysregulation in SAD.

Acceptability, Feasibility and Preliminary Outcomes of the Kiso Mind App for Outpatients With Schizophrenia Spectrum Disorders

The Kiso pilot study is a randomized controlled trial to test the acceptability and feasibility of a novel digital intervention, namely the Kiso Mind smartphone app. A parallel-group design is utilized. Participants either receive access to the Kiso Mind intervention and treatment-as-usual (TAU) in the experimental condition or receive treatment as usual (TAU) in the control condition. The intervention is designed for participants diagnosed with either schizophrenia (F20.0) or schizoaffective disorder (F25.0) according to the ICD-10. To examine acceptability, feasibility, and preliminary effectiveness, both self-report and rater-based assessments are administered at baseline (T0) and at the end of the 12-week intervention period (post-intervention T1). Lastly, a qualitative interview will be conducted with participants from the experimental condition. The primary outcome of the present study is the acceptability and feasibility of the Kiso Mind app. The secondary outcome consists of general psychopathology, and positive-, negative-, depressive symptoms, as well as social functioning and self-efficacy ratings.

Enhancing Veteran-Clinical Collaboration in VA PRRCs

Over 60% of Veterans with serious mental illness have a service-connected disability that impairs their ability to work, go to school, and/or have successful personal lives. Although traditional treatments tend to focus on symptom remission, Veterans prioritize a range of treatment goals, including personal empowerment and gaining personally meaningful skills. Increasing Veteran-clinician collaboration can help effectively align care with each Veteran's goals and support an empowering therapeutic experience. This project will evaluate the effectiveness of a group-based intervention intended to increase Veterans' comfort, confidence, knowledge, and skills to collaborate with their treatment teams. Findings from this study will contribute important knowledge about this intervention's effectiveness and how to enhance its effectiveness, especially for Veterans from minoritized groups. If the decision-making intervention is effective, it would help Veterans with serious mental illness, and might also help Veterans with other chronic health conditions, like PTSD and chronic pain.

Enhancing Rehabilitation for Veterans With Serious Mental Illness

This study addresses the critical need for innovative therapeutic interventions in Veterans with serious mental illnesses (SMI) receiving care in VA Psychosocial Rehabilitation and Recovery Centers (PRRCs). The vast majority of individuals with SMI suffer from cognitive impairments, leading to chronic functional disability, and impaired outcomes, causing a significant strain on support networks and the VA healthcare system. This study aims to introduce an innovative mental health therapy, Targeted Cognitive Training (TCT), to Veterans struggling with serious mental illnesses (SMI). TCT works to improve basic sensory information processing and, ultimately, clinical, cognitive, and psychosocial functioning. By using EEG biomarkers to identify Veterans with SMI receiving care within VA Psychosocial Rehabilitation and Recovery Centers who are most likely to benefit from this treatment, and by understanding how best to implement this therapy, the investigators hope to enhance care and improve life quality for Veterans with SMI.

Impact of Medication Education on Adherence and Side Effects

Severe mental disorders such as schizophrenia, bipolar disorder, and psychotic depression often require long-term or lifelong medication treatment. However, many psychiatric patients have difficulty adhering to their prescribed medication regimens due to factors such as lack of information, fear of side effects, and negative experiences with psychotropic medications. Poor treatment adherence is associated with symptom relapse, prolonged hospitalization, increased rehospitalization rates, reduced quality of life, and higher health care costs. Medication education is a key psychosocial intervention aimed at improving patients' understanding of their illness, treatment process, and potential medication side effects. Providing structured medication education may enhance treatment adherence and help patients recognize and manage side effects more effectively. This intervention study aims to evaluate the effect of a structured medication education program on treatment adherence and medication-related side effects among psychotic inpatients hospitalized in a psychiatric clinic, including patients diagnosed with schizophrenia, schizoaffective disorder, schizophreniform disorder, bipolar disorder with psychotic features, and major depressive disorder with psychotic features. The findings of this study are expected to contribute to the development of effective psychosocial interventions to improve medication adherence and treatment outcomes in psychiatric inpatient settings.

Integrative Neuro-social Cognitive Strategy Programme for Instilling REcovery (INSPIRE) a Community-Based Cognitive Remediation Trial

Adults with serious mental illnesses (such as schizophrenia and schizoaffective disorders) often experience a range of cognitive difficulties (such as memory, problem solving difficulties) that affect their ability to lead meaningful life roles. Cognitive remediation is an intervention to address cognitive difficulties in this group of mental health service users. Its implementation in less well-resourced community-based settings is less well-studied. Therefore, the aims of the study are: * To investigate the effects of cognitive remediation on various cognitive skills (such as attention, memory, problem-solving, facial expression recognition, taking others' perspectives etc), for participants with schizophrenia or schizoaffective disorders in community mental health settings. * To investigate if factors such as participants' motivation for engagement and social interaction can affect changes in cognitive skills and functional ability. Participants in the treatment group will attend computer-based cognitive exercises to improve their cognitive skills. They will also participate in group sessions facilitated by therapists to learn how to utilize strategies learned from the computer sessions in their daily lives. Participants in the control group will attend the usual rehabilitation activities in their respective community-based psychiatric rehabilitation centers. This research study will compare the differences in their cognitive performance, functional ability and recovery immediately after the intervention and 8 weeks later.
