Low Amplitude Pulse Seizure Therapy Versus Standard Ultra-Brief Right Unilateral Electroconvulsive Therapy
This protocol proposes an initial randomized clinical trial that includes all patients with suicidal ideation (SI) at baseline, and with SI as the primary outcome measure to examine whether Right Unilateral Low-Amplitude Pulse - Seizure Therapy (RUL LAP-ST) treatment has more magnitude and rate of remission of SI as conventional pulse amplitude Right Unilateral Electroconvulsive Therapy (RUL ECT) (based on our prior secondary analysis). Our central hypothesis is that RUL LAP-ST has significantly less cognitive/memory side effects (no memory side effects were noted in our prior studies for 500mA and 600mA) and thus is more favorable in terms of side effects compared to RUL conventional pulse amplitude ECT, while maintaining better anti-suicidal effect.

D-serine AudRem: R33 Phase
Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the D-serine treatment over 16 weeks of a program designed to measure auditory plasticity.

Cognitive Neurocomputational Task Reliability and Clinical Applications Consortium: Study 2
In Study 2, investigators will recruit individuals with schizophrenia (SZ) and or schizoaffective disorder (SZA) and healthy controls (HC) using optimized behavioral tasks to replicate the behavioral findings from Study 1 and to assess additional psychometric properties such as test re-test reliability and practice effects. Investigators will obtain data on: A) clinical symptoms, with detailed assessment of hallucinations and delusions; B) community functioning; and C) functional capacity, allowing us to examine clinical validity. To generate a sample with sufficient variation in hallucinations and delusions, investigators will recruit the following groups that balance feasibility with clinical relevance: A) healthy controls \[HC, N=125\]; B) schizophrenia and schizoaffective disorder \[SZ/SZA, N=200\]). Investigators anticipate a \~20% screen fail/drop-out rate based upon prior studies. Thus, investigators will run an additional 40 SZ/SZA and 15 HC. Investigators will administer tasks optimized in Aim 1 without electroencephalogram (EEG), to this new sample of individuals with SZ/SZA and HC. All participants will be retested after approximately 28 days and repeat clinical assessments. Although the investigators' goal is to shorten task length using the Study 1 analyses, they will administer longer tasks than optimal for public dissemination in Study 2 to determine the minimum number of trials required for acceptable reliability. Study 2 will use the same clinical and functional measures as Study 1.

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

REACH Study (Recovery Environments: Assessing Cognitive & Brain Health in Community Mental Health)
The purpose of this study is to understand how different types of community-based mental health care affect thinking abilities, daily functioning, and brain activity in adults with schizophrenia and related conditions. The investigators are especially interested in learning whether the Clubhouse Model-a structured, supportive community for individuals with mental illness-has unique benefits compared to standard outpatient mental health services. If participants decide to join, they will be asked to complete a total of six study visits with the research team over the course of your participation. Three of these study visits are at the beginning (baseline) and the remaining three are six months later. Two of the three visits will includes interviews, questionnaires, and thinking and memory tasks (cognitive testing) and one session will be an MRI brain scan, which is a safe and non-invasive imaging procedure. The total time required for each visit will be approximately 90 minutes to two hours. Participants may take breaks as needed.

TOPUS - Testing an Implemented Intervention to Reduce Duration of Untreated Psychosis
This study examines whether an early-detection program for psychosis can shorten the time patients remain untreated after the first appearance of psychotic symptoms, and whether such a reduction improves later functioning for people with first-episode schizophrenia. Psychosis involves symptoms such as hallucinations and delusions. When these symptoms are recognized and treatment begins, most patients improve. However, many individuals live with psychotic symptoms for months-or even longer-before receiving care. This period is known as the duration of untreated psychosis (DUP). A long DUP has repeatedly been linked to poorer long-term outcomes, but it is still unclear whether DUP itself causes worse outcomes or simply reflects different illness courses. In Denmark, Region Zealand has implemented a large-scale early-detection effort. This includes public awareness campaigns and a specialized team that identifies people with emerging psychosis and helps them start treatment quickly. The Capital Region of Denmark provides usual care without these additional initiatives. This situation makes it possible to compare two regional systems that differ in their approach to early detection but provide the same specialized treatment once patients enter care. The study follows a quasi-experimental design, recruiting adults (18+) who receive a first diagnosis of a schizophrenia-spectrum disorder within the OPUS early-intervention programs in the two regions. No interventions are assigned by the research team; participants receive standard clinical care. Researchers conduct interviews to establish how long psychotic symptoms were present before treatment began and to assess functioning and symptoms over a two-year follow-up period. Functioning, symptoms, cognition, and treatment factors will be examined at baseline and at follow-ups. The study addresses three questions: Whether early-detection efforts in Region Zealand reduce the duration of untreated psychosis compared with usual detection. Whether a shorter duration of untreated psychosis leads to better functional and clinical outcomes fifteen months after treatment begins. How DUP can best be defined and measured so that it reliably predicts later outcomes. Results may provide evidence for whether early-detection services improve timely access to care and whether reducing the duration of untreated psychosis contributes to better long-term functioning. The study may also help establish clearer international standards for how DUP should be measured in both research and clinical practice.

EPI-MINN: Targeting Cognition and Motivation - National
The purpose of this study is to perform a practice-based research project designed to assess whether cognition and motivated behavior in early psychosis can be addressed as key treatment goals within real-world settings by using a 12-week mobile intervention program. We will recruit participants who are receiving care for early psychosis from clinics across the United States. We will compare outcomes from participants who receive treatment at coordinated specialty care (CSC) early psychosis clinics to those that receive standard community care. A qualifying CSC program will provide comprehensive clinical services such as psychotherapy, medication management, psychoeducation, and work or education support. This study will be conducted remotely, and participants can participate at home with their own electronic devices. The aim of this study is to investigate a well-defined 12-week mobile intervention program specifically designed to target cognitive functioning and motivated behavior for individuals with early psychosis. Participants will complete a screening interview which will include diagnosis and symptom ratings, neurocognitive assessment, and self-reports of symptoms, behavior, and functioning. Then participants will be randomized to receive the 12-week mobile intervention, or an active control of treatment as usual. The investigators will test for differences in the clinical trajectories after training, and at two follow up appointments at 6 and 12 months post-training.

Using Transcranial Magnetic Stimulation (TMS) to Understand 'Negative' Symptoms of Schizophrenia
The main purpose of this study is to learn how transcranial magnetic stimulation (TMS) helps improve negative symptoms of schizophrenia. These 'negative symptoms' include anhedonia (the inability to enjoy things), low motivation, and decreased facial expression. TMS is a noninvasive way of stimulating the brain. TMS uses a magnetic field to cause changes in activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study we will be stimulating the brain to learn more about how TMS may improve these symptoms from schizophrenia.

Getting Out of the House: Using Behavioral Activation to Increase Community Participation
The goal of this study is to evaluate the effectiveness of an behavioral activation intervention to increase meaningful activity and community participation for people with serious mental illness. The overall objective of this study is to increase engagement in meaningful activities and community participation. The objectives of the project are as follows: 1. To determine if the intervention leads to increases the frequency and variety of activities. 2. To determine if the intervention leads to increases in community mobility. 3. To determine which demographic and environmental factors and mechanisms of action impact the effectiveness of the intervention. 4. To determine if the the intervention leads to an improvement in overall well-being (e.g., improved quality of life). Participants will be asked to attend a 2-hour weekly online session for 10 weeks and then a 1-hour online monthly session for a 3 month maintenance period. For data collection, participants will also be asked to: 1. Complete three, approximately 1-hour interviews at baseline, after the 10 week intervention, and again at the end of the maintenance period; 2. Carry a mobile phone with a global positioning system app to track their movements outside their home for 2 weeks at a time, at three separate times (e.g., baseline, after the intervention, and at the end of the maintenance period); and 3. Complete a 15 minute weekly interviews for 26 weeks about their daily activities and participation. The study will enroll 52 participants split into 4 cohorts of 13. The study will use a multiple baseline design and, as such, all participants will receive the intervention and there is no control group.

Multi-modal Assessment of Gamma-aminobutyric Acid (GABA) Function in Psychosis
The purpose of this study is to better understand mental illness and will test the hypotheses that, while viewing affective stimuli, patient groups will show increased blood oxygenation level dependent (BOLD) signal by fMRI after lorazepam. This study will enroll participants between the ages of 16 and 60, who have a psychotic illness (such as psychosis which includes conditions like schizophrenia, schizoaffective disorder, and mood disorders like bipolar disorder). The study will also enroll eligible participants between the ages of 18 and 60 without any psychiatric illness to compare their brains. The study will require participants to have 3-4 sessions over a few weeks. The initial assessments (may be over two visits) will include a diagnostic interview and several questionnaires (qols) to assess eligibility. Subsequently, there will be two separate functional magnetic resonance imaging (fMRI) sessions in which lorazepam or placebo will be given prior to the fMRI. During the fMRI, the participants will also be asked to answer questions. Additionally, the participants will have their blood drawn, vital signs will be taken, they will be asked to complete more qols, and women of childbearing potential will have a urine pregnancy test.

Neurotransmitters in Treatment Resistant Schizophrenia Patients With add-on Sodium Benzoate
Although antipsychotic is effective for schizophrenia, however, still certain proportion of patients were not responsive to treatment. Treatment resistant schizophrenia (TRS) is accompanied by function decline and heavy burden. In recent decades, the biological mechanism of schizophrenia extended from dopamine theory to the role of glutamate system. This shift could be an alternative pathway to developing the treatment of TRS. Sodium benzoate (SB) could be an option as a glutamatergic agent for the patients with TRS. However, most evidence of SB is for treating patients with schizophrenia and other mental disorders but the evidence for treating patients with TRS is scarce. To predict the treatment response of SB will be an urgent topic in the future. Little is known about the precise medicine for treating patients with TRS. The present project will extend our pilot randomized clinical trial on SB for TRS. A total of 90 patients with TRS will be enrolled from three centers and will be assigned to 8 weeks of treatment with SB or placebo (2:1). A comprehensive battery of potential markers will be employed, including 1H- magnetic resonance spectroscopy (MRS), brain functional connectivity, genotyping, immune biomarkers, cognitive function, and clinical characteristics. The efficacy of SB on TRS will be confirmed in this project. Predictors for treatment response will be identified. Artificial intelligence algorithms will be used for probing the feasibility of precision medicine.

Exploring the Feasibility of Transcranial Ultrasound Stimulation in the Treatment of Schizophrenia
1. The purpose of this study is to evaluate the safety and feasibility of transcranial ultrasound stimulation (TUS) treatment in patients with schizophrenia. Subjects are individuals diagnosed with schizophrenia who will receive non-invasive, low-intensity pulsed ultrasound stimulation targeting the hippocampus and its surrounding regions. Evaluations will be conducted before and after the treatment sessions, including electrocardiograms (ECG), blood biochemistry tests, psychiatric symptom assessments, depression level assessments, and cognitive function assessments. 2. The primary objective is to assess the safety of this intervention in patients with schizophrenia. The secondary objective is to explore whether the current stimulation parameters may lead to improvements in the assessed symptoms. Ultimately, this study aims to support the future application of low-intensity pulsed ultrasound as a potential intervention to alleviate symptoms of schizophrenia and improve patients' quality of daily life.

Clinical Trial of an IL-23 Inhibitor for Immune Activation in Clinical Trial of an IL-23 Inhibitor for Immune Activation in People With Schizophrenia
This 16 week clinical trial investigates a precision-medicine approach to schizophrenia by targeting a biologically distinct subgroup,-approximately one-third of patients-characterized by the presence of anti-gliadin antibodies (AGA IgG+) which is associated with elevated inflammation in the IL-23/IL-17 immune axis (Th17 pathway). This specific biotype is associated with pronounced negative symptoms, cognitive deficits, and reduced white matter integrity. Building on evidence that this pathway can be modulated to improve clinical outcomes, we are conducting a randomized, double-blind clinical trial of mirikizumab, an FDA-approved monoclonal antibody targeting IL-23, in addition to current antipsychotics, in schizophrenia patients who are positive for AGA IgG. The primary objective is to determine whether mirikizumab - a repurposed FDA approved monoclonal antibody treatment inhibiting IL-23-- will be superior to placebo in treating experiential (e.g., anhedonia and asociality) negative symptoms and cognitive impairments. Secondary aims will be to assess changes in T-cell subtypes and relative abundance by gene expression, peripheral cytokines, and neuroimaging markers (in a smaller subset). By focusing on this patient subgroup, who are identified by their immune status, the research aims to provide a targeted, revolutionary treatment for symptoms that have traditionally remained resistant to standard antipsychotic therapies. This protocol includes a screening phase, with a separate consent form which is intended to identify those with AGA IgG antibodies. This screening portion will also serve to compare other aspects of immune functioning and the TH17 pathway between patient groups and controls in order to further characterize and show that Th17 (and similar immune cell lines) are different between AGA IgG positive, AGA IgG negative and healthy controls of either status.
