Schizophrenia - marked by delusions, hallucinations, and cognitive deficits - causes the most disability of any mental health condition, but existing treatments have significant side effect burden and are often ineffective. Disordered neural activity in the hippocampus likely contributes to schizophrenia symptoms, but to develop better therapies we need to understand whether hippocampal activity in schizophrenia can be systematically affected by non-invasive brain stimulation techniques like transcranial magnetic stimulation (TMS). This proposal will investigate the use of connectivity-guided theta burst brain stimulation to specifically target hippocampal function in schizophrenia, offering insights into fundamental hippocampal processes, schizophrenia pathophysiology, and potential avenues to use brain stimulation as a therapeutic tool in this devastating illness.
NCT06641297
Schizophrenia spectrum disorders are associated with impairment in the microstructure of white matter, the key brain tissue responsible for fast communication between different brain regions necessary for any complex task. This white matter impairment is linked to problems with cognition in schizophrenia, especially slower processing speed. This project aims to study the potential for correcting white matter deficits in schizophrenia by examining mechanisms underlying white matter structure changes in response to training on playing a mock musical instrument.
NCT06957808
Schizophrenia is a condition that causes symptoms like delusions, hallucinations, reduced motivation and muddled thinking. It is a common, severe and disabling psychiatric illness affecting about 1/100 (1%) of people. It is ranked the third most disabling illness worldwide. Six in seven patients do not recover from the illness in 6-12 months and continue to experience psychotic symptoms. Therefore, there is a strong unmet need for new evidence-based treatments to target the neurobiology underlying schizophrenia. There is increasing evidence to indicate that glutathione (GSH), the main brain antioxidant, is abnormal in schizophrenia and may provide a new treatment target. In this study, the investigators plan to determine whether Diroximel Fumarate (DRF) (currently a treatment for a brain disorder called multiple sclerosis) can increase GSH in the brain of patients with schizophrenia using a brain scan (MRI) and explore whether changes in GSH are related to other brain measures (measured with MRI and EEG- which measures electrical activity in the brain), blood markers of GSH, and symptoms. During this study 30 people with schizophrenia will be recruited. Participants will take the drug DRF for two weeks, a computer will then decide randomly whether each person will continue to take DRF or a placebo/dummy pill for another two weeks. During this part of the study neither the patients nor the researchers will know which type of drug the patient is taking. Brain GSH and the other measures described will be assessed before and after taking the DRF and placebo/dummy pill. At the end of the study (2027), the investigators will see if taking DRF alters the brain chemical (GSH) in people with schizophrenia and whether this is linked to other measures and symptoms. It will also give researchers information about the best way to design future studies for patients with schizophrenia using this drug.
NCT06939088
Glucagon-like peptide-1 receptor agonists (GLP-1RAs), approved for the treatment of type 2 diabetes and obesity, have shown promise as a novel treatment for alcohol use disorder (AUD). This study aims to investigate whether the Glucose-dependent Insulinotropic Polypeptide/GLP-1RA tirzepatide will reduce alcohol consumption in patients with a dual diagnosis of AUD and schizophrenia, a population in dire need of improved treatment options. To further investigate the neurobiological underpinnings of a potential dampening effect on alcohol consumption, functional magnetic resonance imaging (fMRI) brain scans will be applied. The key anticipated outcomes include: * decreased alcohol consumption and * reduced alcohol cue-induced brain activity in the GIP/GLP-1-treated patient group compared with the placebo group. To the best of the investigators knowledge, this has never been examined before.
NCT06674694
Study to evaluate the safety and tolerability of single ascending doses of brexpiprazole long-acting injection in healthy subjects/patients with schizophrenia.
NCT06911723
This is a study investigating how brief online activities can influence mood and attitudes.
NCT07091344
This study aims to evaluate the relationship between cognitive, metacognitive and social cognition variables in patients with psychosis undergoing VR-based Avatar Therapy for the treatment of auditory hallucinations. In addition to the primary intervention, participants will be assessed using validated tools for emotion recognition, attributional style, theory of mind, neurocognition, and metacognition. The study also explores the potential role of trauma as a predisposing factor. Assessments will be conducted at four time points: screening (week 0), baseline (week 12), intervention period (weeks 12-24), and post-therapy follow-up (week 24). By investigating these variables, this study seeks to better understand their impact on treatment outcomes and contribute to the development of personalized therapeutic approaches.
NCT06949657
ACT combined with stratified intervention improved cognitive function and quality of life in elderly schizophrenia patients by enhancing psychological flexibility and family support.
NCT07027085
Despite all the positive facts about the use of virtual reality technology in the assessment and treatment of schizophrenia, there are few publications per year. There are few controlled studies covering the effectiveness of virtual reality programs in the training of cognitive and social skills. In future research, more randomized studies with more robust samples are expected, because the results of experimental studies so far encourage this new treatment approach. Therefore, the aim of this study is to examine the effects of virtual reality application on sensory, social and cognitive areas in individuals with schizophrenia.
NCT06936397
This study aims to determine whether Cognitive Remediation Therapy (CRT) can improve attention, memory, and emotional regulation in people with schizophrenia. CRT is a structured program that includes exercises to strengthen cognitive skills such as problem-solving, working memory, and emotion regulation. The study will recruit 60 participants: 30 individuals with schizophrenia and 30 healthy individuals of similar age and gender. Those with schizophrenia will be randomly assigned to either receive CRT or be placed on a waitlist without therapy. All participants will undergo non-invasive brain activity (EEG) and emotional response (GSR) recordings before and after the therapy. The study's main question is: Does participating in a 12-week CRT program improve brain-based markers of attention and emotional regulation in people with schizophrenia? Additional tests, such as memory and emotion recognition tasks and self-report questionnaires, will help assess changes in thinking skills and emotional well-being. The study may help better understand how CRT affects both brain function and quality of life in schizophrenia.
NCT06692530
Rationale: Ethnic minorities and asylumseekers have a two- to three-times increased risk of psychosis compared to people from their host country. Among patients experiencing psychosis, paranoid delusions are a common symptom. Diagnostic assessments are challenging in this group because of language differences and sociocultural differences in interpersonal social behavior and communication. To fill this gap this research will make use of Virtual Reality (VR) to assess thoughts, behaviours and emotions in real-time. VR has a high ecological validity and its partial non-verbal nature has a clear potential in terms of a transcultural application among asylumseekers. Objective: The main objective of this study is to discover how asylumseekers with a psychotic disorder who are experiencing paranoid delusions behave and evaluate threat in a virtual environment. Secondary objectives: To assess the suitability and applicability of using VR within the specific population of asylumseekers with a psychotic disorder and paranoid delusions. Study design: The study uses a mixed-methods design, combining qualitative phenomenological data and descriptive quantitative data. Study population: Adult psychiatric patients that are seeking asylum in the Netherlands with a DSM-5 classification of a psychotic disorder and paranoid delusion (as measured by the PANSS) will be included. Furthermore, patients must receive mental health care from CTP Veldzicht, either in one of the wards (closed or open) or through ambulatory care. Intervention: The patients will be immersed in a VR-environment using a head mounted display. Four different VR-scenarios are used, each taking up three to four minutes. Using simple movement instructions, patients are asked to walk around and observe their environment. Main study parameters/endpoints: Phenomenological semi-structured interview. The interview measures the experience of participants in a qualitative matter. Audio recordings of the semi-structured interviews will be transcribed. These transcriptions containing rich qualitative data are the main study parameter. Additional descriptive qualitative data (demographic \& symptom specific) will be gathered through questionnaires to provide quantitative insight in the sample-population (questionnaires used: PANSS, SSPS, SBQ, and VAS). Subsequently, psychiatrists working in the field of transcultural psychiatry will be interviewed about the paranoid behaviour of participants based on video and audio recordings of the VR-session. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Some participants might experience simulator sickness symptoms. No major adverse events are expected or have been documented in previous VR studies of our research group using the same VR hardware and software. The assessment will take approximately 90 minutes in total. No benefits are expected. An empathic and transparent approach, a clear consent procedure, close monitoring of participants' moods and consistently adverting an opt-out will be used.
NCT06907420
In schizophrenia, an abnormal reduction in neuronal gamma oscillations (30-100 Hz) is associated with negative symptoms such as cognitive dysfunction. The literature suggests that rescuing gamma oscillations through non-invasive brain stimulation may be an accessible and safe add-on strategy to mitigate negative symptoms. Here, a stimulation protocol based on gamma visual stimulation will be tested. This pilot study will follow an uncontrolled clinical trial design: A minimum of ten patients diagnosed with schizophrenia or a schizoaffective disorder and predominant negative symptoms will be recruited at Klinikum rechts der Isar. They will undergo a multisession stimulation protocol, consisting of one hour of 40 Hz visual stimulation per day over five consecutive days, during which they will be encouraged to fall asleep. An equal number of patients will be recruited for a treatment-as-usual group without intervention. Pre- and post-assessments will include EEG, a cognitive test battery (THINC-IT), a mood scale (PANAS), and a schizophrenia symptom scale (PANSS). This study's results will inform on the feasibility of gamma visual stimulation as a potential add-on intervention in schizophrenia.
NCT06886945
Schizophrenia (SCZ) is a severe neuropsychiatric disorder characterized by cognitive decline, social withdrawal, and positive symptoms such as hallucinations and delusions. Research suggests that SCZ and schizotypy exist along a continuum, with shared structural and behavioral abnormalities, the latter of which encompass the sensory and perceptual domain, often in the form of altered multisensory integration, as seen in tasks like the Sound-Induced Flash Illusion (SIFI). Individuals with schizotypal traits or SCZ show enlarged temporal binding windows (TBW) of cross-modal integration, affecting perceptual accuracy and multisensory judgments. However, whether these deficits stem from overactive top-down modulation or weakened bottom-up sensory precision remains unclear. The current study seeks to address these questions, by asking participants (healthy individuals screened as for their schizotypal traits, and patients suffering from SCZ) to complete a modified version of the SIFI, as well as an audiovisual temporal order judgment (TOJ) task. Cross-modal performance will be assessed via signal detection theory (SDT) metrics and psychometric modeling to estimate individual TBWs, thereby assaying audiovisual processing abilities along the schizotypal continuum
NCT06838104
Schizophrenia is a chronic mental health disorder that affects thoughts, emotions, and behaviors. It includes positive symptoms such as hallucinations and delusions, as well as negative symptoms like reduced motivation, social withdrawal, and blunted emotional expression. This study is a randomized, placebo-controlled trial designed to evaluate the effect of melatonin on schizophrenia symptoms. Melatonin, a natural hormone that regulates sleep, has antioxidant properties and potential neuroprotective effects. A total of 76 patients diagnosed with schizophrenia according to DSM-5 criteria will be randomly assigned to receive either melatonin (6 mg daily) or a placebo for eight weeks while continuing their standard risperidone-based antipsychotic therapy. Symptoms will be assessed at baseline and after 8 weeks using the Positive and Negative Syndrome Scale (PANSS), a validated tool for measuring schizophrenia severity. The primary outcome will be changes in PANSS scores, evaluating whether melatonin leads to significant improvement compared to placebo. The study hypothesizes that melatonin will significantly reduce positive and negative symptoms compared to placebo. Findings from this research may help determine whether melatonin can be used as an adjunctive treatment in schizophrenia, potentially improving clinical outcomes and quality of life for patients.

Mental health disorders, with a 30% annual prevalence rate, are a leading cause of disability and reduced life expectancy. Despite their impact, patient-reported experience measures (PREMs) and outcome measures (PROMs) are underutilized in psychiatry. MonPsy\&Moi®, a digital platform funded by ATIH and DGOS, addresses this gap by providing a user-friendly tool to assess patient experiences and outcomes in real-time, aiming to improve the quality of psychiatric care across France. The study consists of two stages: Stage 1 (No Feedback): MonPsy\&Moi® is deployed across 12 psychiatric facilities, collecting patient data without feedback to clinicians. Objectives include assessing implementation feasibility, validating adaptive questionnaires (PREMIUM), and identifying predictors of patient outcomes, such as relapse and healthcare utilization. Stage 2 (With Feedback): Focuses on patients with severe mental illnesses (schizophrenia, bipolar disorders, and major depressive disorders). This stage evaluates the impact of providing PREMs/PROMs feedback to clinicians on relapse rates, healthcare costs, and overall patient outcomes. MonPsy\&Moi® uses adaptive questionnaires tailored to psychiatric care, covering key domains such as dignity, information, interpersonal relationships, care environment, and treatment. It also evaluates health-related quality of life, including psychological well-being, autonomy, self-esteem, and social relationships. The platform integrates with national healthcare databases (SNDS) to enhance data analysis and predict patient trajectories. The study will involve over 22,000 participants in Stage 1 and 1,100 participants in Stage 2, using a quasi-experimental design to compare feedback and non-feedback strategies. Results aim to demonstrate the feasibility, acceptability, and efficacy of MonPsy\&Moi® in improving mental health outcomes and guiding national psychiatric care policies. By empowering patients and clinicians with actionable insights, MonPsy\&Moi® aspires to set a new standard for patient-centered mental healthcare in real-world settings
NCT06729541
Schizophrenia (SCH), major depressive disorder (MDD), and bipolar disorder (BPD) are prevalent, disabling psychiatric conditions that not only cause significant suffering for affected individuals and their families but also impose a substantial socioeconomic burden and challenge societal well-being. Addressing the mental health challenges faced by patients, their families, and the healthcare system is a critical global public health priority. However, a comprehensive and systematic precision treatment approach for mental disorders remains largely absent in current clinical practice. This study leveraged pharmacogenomic insights tailored specifically to the Chinese Han population to guide individualized medication selection. The approach incorporated quantitative assessment-based treatment protocols alongside therapeutic drug monitoring throughout the treatment process. The overarching goal was to establish a systematic precision treatment model that integrates "quantitative assessment-based treatment + pharmacogenomics + therapeutic drug monitoring." This model aims to optimize treatment outcomes, enhance safety, improve efficiency, and reduce costs, ultimately benefiting patients with psychiatric disorders.
