Studies of Frontal Lobe Brain Functioning in Schizophrenia

The purpose of this study is to use brain imaging technology to investigate the role of the frontal lobe of the brain in the thinking of individuals with schizophrenia and other neuropsychiatric disorders and healthy volunteers. Participants in this study will undergo a positron emission tomography (PET) scan of the brain while performing neuropsychological tests. Some of the tests involve cognitive operations that depend upon the frontal cortex. Interactions between frontal lobe activation, cognitive behavior, and neuropharmacology will be assessed by measuring regional cerebral blood flow (rCBF) during treatment with drugs that may affect frontal lobe physiology.

A Mobile App to Support Mood, Daily Routines and Medication Adherence in Adults With Severe Mental Illness

The goal of this clinical trial is to learn whether MoodSync, a mobile application for patients and their family caregivers, improves mood stability, medication adherence, daily functioning and early detection of relapse warning signs in adults with severe mental illness in Bahrain. The main question it aims to answer is: Does MoodSync plus standard care improve manic symptoms, medication adherence, practical and social functioning, and early warning signs more than standard care alone? Participants will be randomly assigned to MoodSync plus standard care or standard care alone. MoodSync participants will use the patient app for 12 weeks for daily mood check-ins, sleep and activity tracking with a wearable device, medication reminders, daily-routine (social rhythm) support and early warning-sign reporting. A nominated family caregiver may use the linked caregiver app. All participants continue standard care and complete questionnaires before and after the intervention period. Research hypothesis: \* Patients who use MoodSync will show greater improvement in mood symptoms, medication adherence, practical and social functioning, and relapse-related outcomes than patients receiving standard care alone.

Quality of Life, Safety and Compliance of Patients Using Monotherapy or Combinatorial Therapy With Quetiapine for Treatment of Schizophrenia or Bipolar Affective Disorder

The goal of this observational study is to evaluate the quality of life, drug safety and therapy compliance of schizophrenia or bipolar affective disorder patients during the treatment with quetiapine monotherapy or in combination with another antipsychotic/antipsychotics. The main outcome measures are: * quality of life using the World Health Organization Quality of Life questionnaire (WHOQOL) * safety through the monitoring of the incidence of possible adverse drug events by the researcher, with the assessment of the association between the administration of the drug and the occurrence of an adverse reaction * therapy adherence using the Medication Adherence Rating Scale (MARS). The subjects will be divided into two groups: 1. Newly diagnosed patients with a diagnosis of schizophrenia or bipolar affective disorder whose individual therapeutic approach, based on the clinical assessment of the research physician, includes one of the following therapies: 1. monotherapy with the drug quetiapine 2. combined antipsychotic therapy with quetiapine and aripiprazole 3. combined antipsychotic therapy with quetiapine and haloperidol 2. Patients with a diagnosis of schizophrenia or bipolar affective disorder who are on therapy with one of the antipsychotics (aripiprazole or haloperidol), and who, based on the clinical assessment of the investigator, require adjunctive quetiapine therapy. This group will include two subgroups of patients: 1. combined antipsychotic therapy with quetiapine and aripiprazole 2. combined antipsychotic therapy with quetiapine and haloperidol Recruitment of subjects will be carried out by physicians/researchers based on the patient's history and diagnosis. The diagnosis of schizophrenia or bipolar affective disorder will be based on the standard diagnostic criteria in medical practice (validated measurement scales in psychiatry - Young's Mania Scale, Beck Depression Scale and PANNS Schizophrenia Scale). Patients will have four visits to physician/researcher: 1. First visit - baseline at which patient will be included in the study 2. Second visit - 4 months after the baseline 3. Third visit - 8 months after the baseline 4. Fourth visit - 12 months after the baseline

PET Scanning in Parkinson s Disease

This is an in vivo positron emission tomography (PET) study of regional cerebral dopamine and blood flow in normal volunteers, persons with Parkinson s disease (both familial and sporadic), and those with schizophrenia spectrum disorders. The latter also sign consent for NIH approved protocol 89-M-0160, "Inpatient Evaluation of Neuropsychiatric Patients," PI: Daniel Eisenberg, M.D. Using PET with 6-\[F-18\] Fluoro-L-dopa (FDOPA) and (15)0-H2O in a single scan session, both presynaptic dopaminergic function and regional cerebral blood flow (rCBF) are assessed. The kinetic rate constant (Ki) for presynaptic dopaminergic uptake in striatum and other regions is calculated. We compare Ki across subject groups and relate the findings to rCBF. Findings are also related to allelic variation in genes of interest, for determination of which participants sign separate consent for NIH approved protocol 95-M-0150 Neurobiological Investigation of Patients with Schizophrenia Spectrum Disorders and Their Siblings, PI: Karen F. Berman, MD. We also draw comparisons between subjects with inherited vs. sporadic Parkinson s disease to determine whether the PET phenotype is the same in both groups, and we compare system-level, circuit-based pathophysiology across PD and schizophrenia groups. Each subject is further screened with an MRI to rule out structural abnormalities and also to further delineate areas of interest in the PET scans.

Magnetic Resonance Imaging (MRI) of Neuropsychiatric Patients and Healthy Volunteers

The purpose of this study is to use brain imaging technology to compare differences in brain structure, chemistry, and functioning in individuals with brain and mental disorders compared to healthy volunteers. Schizophrenia is a brain disorder that results from subtle changes and abnormalities in neurons. These deficits likely occur in localized regions of the brain and may result in widespread, devastating consequences. The neuronal abnormalities are inherited through a complex combination of genetic and environmental factors. Brain imaging technologies can be used to better characterize brain changes in individuals with schizophrenia. This study will use magnetic resonance imaging (MRI) scans to identify predictable, quantifiable abnormalities in neurophysiology, neurochemistry and neuroanatomy that characterize schizophrenia and other neurological and neuropsychiatric disorders.

Ketogenic Diet in People With Schizophrenia

Schizophrenia is a serious mental disorder with a heterogenous presentation, lack of clear understanding of pathophysiology and only partially effective treatments. First-line antipsychotic drugs block dopamine, but many people continue to suffer from persistent positive or negative symptoms that cannot be fully treated with available medications. Recently, our group has found that dietary modulations have efficacy comparable to antipsychotic medications and that determining which patients could benefit from a personalized treatment framework is critical. The ketogenic diet consists of low-carbohydrate, moderate protein and high fat intake inducing a state in which ketone bodies in the blood provide energy to the cells. In pharmacologic mouse models a ketogenic diet regimen resulted in complete restoration of normal behaviors, independent of strict caloric restriction and other work has suggested that a ketogenic diet may improve schizophrenia like deficits in rodents. An open label ketogenic diet study in the 1950s reported improvement in schizophrenia symptom. At least 7 additional case reports have found robust improvements or complete resolution of schizophrenia symptoms. Recently a retrospective study found robust and significant improvements in schizophrenia symptoms in 10 schizoaffective disorder patients treated with a ketogenic diet. In addition to psychiatric symptoms, improvements in metabolic outcomes have been demonstrated. However, to date, there have been no published double blind randomized controlled trials evaluating the effects of a ketogenic diet since few sites can conduct inpatient trials and have observation and control for food intake

iTBS to Enhance Social Cognition in People With Psychosis

The goal of this clinical trial is to examine if iTBS applied to the DMPFC improves social cognitive performance compared to sham stimulation in people diagnosed with schizophrenia, schizoaffective disorder, schizophreniform disorder, or psychotic disorder not otherwise specified. The main objectives of this trial are: * Compare changes in social cognitive performance between the active vs. sham treatment groups * Compare changes in social cognitive network functional connectivity between the active vs. sham treatment groups Each participant will receive iTBS (active or sham) five days per week for four consecutive weeks. Functional magnetic resonance imaging (fMRI) scans, clinical assessments, and cognitive tests will be performed at pre-treatment, post-treatment, and 6 months after the completion of treatment.

Acceptability and Feasibility of Work-Oriented Social-Cognitive Skills Training for Veterans With Serious Mental Illness

Many individuals with serious mental illness have difficulty accurately interpreting interpersonal cues and effectively engaging in social exchanges. Difficulties related to the interpersonal aspects of work can lead to isolation, poor productivity, and job loss. The goals of this study are to: 1) adapt an evidence-based social cognitive skills intervention for work settings and use with Veterans, 2) examine the acceptability of the work focused skills training intervention, 3) assess the feasibility of combining the social cognitive skills training program with supported employment, and 4) examine change on functional outcomes. The current study will use feedback from veteran and employment specialist stakeholders to adapt an evidence-based social cognitive skills training program, Social Cognition and Interaction Training (SCIT). The intervention will be modified to tailor it to work relationships and to address any unique relationship concerns among Veterans that are identified by stakeholders. SCIT-Work Edition (SCIT-WE) will add: 1) education about work-related social norms; 2) examples of work-related social interactions that require perspective taking and problem- solving; 3) individual sessions with the study therapist to enhance learning and relevance to each participant's goals; 4) structured interactions with the participant's employment specialist to practice skills outside of group; and 5) skill application sessions with the participant's employment specialist that prompt use of skills after training is completed. SCIT-WE will be developed and piloted in an open trial with 20 Veterans enrolled in the supported employment program at the Minneapolis VA who have a qualifying serious mental illness diagnosis. SCIT-WE will be offered for 2 hours weekly over 13 weeks, when most participants are in the job development and job search phases of supported employment. While participating in the group skills training, participants will have weekly, individual homework review sessions with the group facilitator to promote understanding of the skills and to discuss relevance of the skills to personal goals. Participants also will practice skills weekly with their employment specialist for 10-15 minutes to promote use of skills outside of group sessions. In the 3-months following skills training completion, participants will complete 10 15-minute skills review sessions with their employment specialist to encourage continued skill application in a work setting. Participants will complete assessments at baseline, before receiving the intervention; 3-months post-enrollment, after participating in a weekly skills training group; and 6-months post-enrollment, after receiving 10 additional individual skills review sessions with their employment specialist. Accessibility will be measured with rate of treatment uptake, rate of treatment completion, and participant attitudes toward the intervention. Feasibility of the intervention will be assessed by examining retention in supported employment and the study at 3- and 6-months post-enrollment. Impact of the intervention will be examined with measures of quality of life, social adjustment, self-efficacy, and work relationship quality. It is hypothesized that the intervention will be acceptable to Veterans. The investigators predict a 50% treatment uptake rate, a 70% intervention completion rate, and positive ratings on measures of satisfaction, interest, and value. The investigators hypothesize that it will be feasible to complete this intervention in combination with supported employment activities. The investigators predict that retention in both skills training and supported employment will be 75% at 3-months post-enrollment and 60% 6-months post enrollment. The investigators hypothesize that positive change will be seen at 3-months post-enrollment and sustained at 6-months post-enrollment on measures of quality of life and social adjustment. The investigators predicted that self-efficacy regarding return to work will be improved at 3-months post-enrollment. The investigators predict that Veterans will report being productive and having positive work relationships 6-months post-enrollment. The findings will inform the development of a novel intervention targeting the social and functional impairments associated with serious mental illness. The knowledge gained from this study will guide the development of the next generation of interventions. Given that employment is a critical part of recovery, advancement in therapeutic interventions that support Veterans in this process will be of significance.

Neuronavigated rTMS for Treatment-Resistant Auditory Hallucinations

Auditory verbal hallucinations (AVH), such as hearing voices in the absence of an external sound source, are a common and distressing symptom of schizophrenia. In some patients, hallucinations persist despite treatment with antipsychotic medication. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique that may reduce auditory hallucinations by decreasing activity in brain regions involved in auditory and language processing. This randomized, double-blind, sham-controlled study will investigate whether individualized, neuronavigated inhibitory rTMS can reduce persistent auditory verbal hallucinations. Forty adults with medication-resistant auditory hallucinations will be randomly assigned to receive either active rTMS or sham stimulation. For each participant, the stimulation target in the primary auditory cortex will be individually identified using electroencephalography (EEG), acoustic evoked potentials, and magnetic resonance imaging (MRI)-based neuronavigation. Participants will receive two rTMS sessions per day for five consecutive days. The severity of auditory hallucinations will be assessed before and after treatment and at a 28-day follow-up. The study will also investigate whether treatment is associated with changes in brain activity and functional connectivity measured by EEG, including changes in the P300 event-related potential.

Effectiveness of a Board Game Intervention on Cognitive and Functional Outcomes in Older Adults With Schizophrenia

This study aims to evaluate the effects of a scaffolding-based board game intervention on cognitive and functional outcomes in older adults with schizophrenia living in psychiatric nursing homes. Participants will be assigned by clusters to either an intervention group or a control group. The intervention group will receive a 12-week board game training program, while the control group will receive usual care. Cognitive and functional outcomes will be assessed before the intervention, immediately after the 12-week intervention, and three months after the intervention. The study will examine whether the board game intervention can improve cognitive and daily functioning in older adults with schizophrenia.
