Social Isolation and Aging in Schizophrenia

Individuals diagnosed with schizophrenia and related psychotic disorders (SZ) exhibit a markedly elevated risk of premature mortality, with a 10-20-year shorter lifespan relative to the general population. Increased mortality rates in SZ are largely attributable to the early manifestation of medical conditions that normally occur later in life, a process known as 'accelerated aging'. While unhealthy lifestyle behaviors, such as smoking and unhealthy diet, account, in part, for accelerated aging in SZ, the excess of physical comorbidities cannot be solely attributed to these factors. Remarkably, the direct adverse health effects of key clinical characteristics of SZ have rarely been considered. In the general population, the absence of social contact is known to pose enormous challenges for physical health, especially at older ages. Given that social isolation is a persistent and disabling feature of SZ, it is possible that this behavior may contribute to the premature manifestation of health conditions in SZ. Building on rich pilot data pointing to significant associations between social isolation and long-term perceived health in SZ, the overarching goal is to test whether and how social isolation contributes to the health challenges of individuals with SZ as they age. With participants from Europe (EU-GEI) and the US (Olin Neuropsychiatry Research Center), the researchers will create a longitudinal database of 650 participants, including 500 individuals with SZ, and 150 of their unaffected siblings. The researchers will apply an accelerated longitudinal design by reassessing and by examining medical records of research participants who were first evaluated between the ages of 20-55 and are now 40-70 years of age, a period when many medical conditions and health problems tend to manifest. The researchers will determine the age-related association between social isolation and adverse health outcomes in SZ, test for familiality, directionality, and factors moderating this association, and determine the extent to which the COVID-19 pandemic and the resulting imposed lockdowns impacted health in SZ. The researchers will consider generalizability across countries, sexes, and race/ethnicities. The rationale for the proposed research is that in order to facilitate much-needed targeted therapies to prevent early mortality in SZ, the researchers need to better understand factors that contribute to the excess of medical comorbidities in SZ. The central hypothesis is that social isolation, a common and persistent characteristic of SZ, contributes to the excess of physical comorbidities in SZ. To meet the overall goal, the following aims are: (1) Determine the association between social isolation and adverse health outcomes in SZ; (2) Test for the directionality, and moderating factors, of the association between social isolation and health outcomes in SZ, and; (3) Examine whether the COVID-19 pandemic modified associations between social isolation and health outcome in SZ. This study will be the first to comprehensively examine the health impact of social isolation in SZ. The project may show that in SZ socialization in midlife can reduce the risk for poor health outcomes and ultimately facilitate much-needed preventive targeted therapies to reduce early-age mortality in SZ

Digital Implementation Support to Achieve Uptake and Integration of Task-Shared Care for Schizophrenia in Primary Care in India

Schizophrenia represents a significant contributor to the global burden of disease, with this burden disproportionately impacting low- and middle-income countries (LMICs). In India, the burden due to schizophrenia is further exacerbated by low access to effective psychosocial interventions aimed at promoting recovery, rehabilitation, and community tenure, as well as inadequate attention to managing co-occurring chronic medical conditions that result in significantly reduced life expectancy among those living with schizophrenia compared to the general population. A major driver of these alarming gaps in access to care for persons with schizophrenia in India is the limited capacity within primary care settings aimed at addressing the complex co-occurring mental health, physical health, and functional needs of this patient population. There now exists strong evidence demonstrating that community programs delivered in primary care and leveraging psychosocial interventions combined with linkage to specialty psychiatric services are effective for supporting treatment and recovery of schizophrenia in low-resource settings. We will leverage our existing collaboration and robust research infrastructure in both rural and urban settings in Madhya Pradesh and Karnataka, India to conduct a hybrid type 1 effectiveness-implementation trial to evaluate whether the use of a digital platform offers added clinical benefit and can support integration of this task shared care for schizophrenia into routine primary care settings. We will address the following aims: 1) evaluate whether the use of the mindLAMP digital platform can enhance the clinical effectiveness of task-shared community-based psychosocial rehabilitation (COPSI) for individuals with schizophrenia, and 2) determine whether the addition of mindLAMP to the delivery of the COPSI program has an impact on implementation metrics when compared to delivery of COPSI alone.

Clay Therapy in Schizophrenia Patients

In recent years, art therapies have been discussed for their positive effects on mental disorders. One such therapy, clay therapy, is being studied to examine its effect on the functional recovery and individual and social performance of schizophrenia patients undergoing pharmacological treatment.

rTMS for Depressive, Positive and Negative Symptoms, and Physiological Indices of Schizophrenia Patients

Around 40% of schizophrenia patients present depressive symptoms, which are associated with elevated suicide and violence risk and poor prognosis and quality of life. Recent meta-analysis showed the effect size of antidepressants for depressive symptoms of schizophrenia patients was as low as 0.25, so new therapeutic approach is warranted. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, anesthesia-free brain stimulation therapy for treatment refractory depression. Currently, rTMS is classified as high-frequency stimulation (\>5Hz, usually 10Hz or 20Hz) and low-frequency inhibition (usually 1Hz). Intermittent theta burst stimulation (iTBS) is a new variant of rTMS, with stimulation frequency as high as 50Hz. Compared with high-frequency rTMS, iTBS has similar therapeutic effect and shorter stimulation duration. Up to now, studies exploring treatment effect of rTMS or iTBS for schizophrenia patients mainly focused on negative symptoms rather than depressive symptoms. Therefore, this study aims to explore treatment effect of rTMS or iTBS of depressive symptoms, negative symptoms, cognitive function and physiological indices for schizophrenia patients.

Intensified Pharmacological Treatment for Schizophrenia, Major Depressive Disorder and Bipolar Depression After a First-time Treatment Failure

Schizophrenia, bipolar and major depressive disorders collectively affect over 10 million people across the EU and are associated with annual healthcare and societal costs in excess of 100 billion Euros. When diagnosed with one of these disorders, patients are prescribed psychotropic medication such as antidepressants, mood stabilisers or antipsychotics. It is unknown whether this first-line treatment will be successful. After this first-line treatment fails, usually a second-line treatment is initiated, and when this is not successful either a third-line treatment is initiated. Third-line treatments are quite successful, especially when compared to second-line treatments. The research question is whether the third-line treatments (early-intensified treatments) when used earlier in the disease course for schizophrenia, bipolar and major depressive disorders. If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments and adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs.

Exercise Therapy in Mental Disorders-study

The study will compare standard high-intensity training with brief high-intensity training in people with schizophrenia-spectrum or bipolar disorder. The overall aim is to determine which of the two is superior in a long-term perspective.

Bilateral Prefrontal and Insular TMS for Depression in Schizophrenia

The purpose of this study is to provide an effective repetitive transcranial magnetic stimulation (rTMS) treatment for depressive symptoms in patients with schizophrenia. Schizophrenia patients with depressive symptoms will be exposed to rTMS to improve their symptoms.

Ketosis Impact on Signs & Symptoms of Schizophrenia and Bipolar disorderS

The goal of this clinical trial is to learn if a ketone drink can improve signs and symptoms of patients with a schizophrenia-spectrum disorder (SSD), or a bipolar-spectrum disorder (BD). The main questions it aims to answer are: Does a ketone drink improve information processing in patients with SSD/BD? Other questions it aims to answer are: Does a ketone drink improve cognitive functioning in patients with SSD/BD? Does a ketone drink improve metabolism and inflammation in patients with SSD/BD? Does a ketone drink affect circadian rhythm in patients with SSD/BD? Research will compare the effects of the ketone drink with that of an isocaloric carbohydrate drink in the same patients ('cross-over'). Participants will: 1. drink a ketone drink and (after a wash-out period) an isocaloric control drink (randomized order); after each drink: * EEG/EMG to determine information-processing parameters (PPI and P300) * cognitive tests * visual analog scale of mood, energy levels, ability to focus * indirect calorimetry to determine use of energy substrate * blood draws 2. for 5 consecutive days: * wear a continuous glucose monitor (CGM) * wear a non-invasive passive sweat biomarker sensor (EnLiSense device) * register a diet and nicotine diary * saliva sampling (max. 5x/day)

SPARK Healthy Sleep

SPARK-Healthy Sleep is a digital mental health intervention designed to help college students who may be at risk for psychosis and experience sleep problems. About 1 in 4 college students report psychotic-like experiences (such as hearing voices or feeling paranoid), and these students often have poor sleep quality, which can worsen their mental health symptoms. This study tests whether a single-session digital intervention can improve sleep and reduce mental health stigma in at-risk college students. The intervention is delivered through a smartphone app and takes about 30 minutes to complete. It includes educational content about mental health being on a continuum (not just "normal" vs "abnormal"), strategies to reduce stigma around seeking help, and evidence-based sleep improvement techniques based on cognitive behavioral therapy for insomnia. The study will recruit 115 college students from Indiana University-Indianapolis who score high on measures of psychotic-like experiences and poor sleep quality. Half will receive the intervention immediately (experimental group), while the other half will wait three weeks before receiving it (control group). All participants will complete questionnaires about sleep, mental health symptoms, social functioning, and stigma at the beginning of the study and after two weeks. The main goals are to determine if the intervention is feasible and acceptable to students, and whether it shows preliminary effectiveness in improving sleep quality, reducing stigma, and improving overall mental health outcomes. A subset of participants will also complete interviews about their experience using the intervention. This research addresses important barriers to mental health care for college students, including stigma and limited access to services. If successful, this digital approach could provide a scalable way to help at-risk students improve their mental health and potentially prevent more serious problems from developing.

The Effect of a Six Week Intensified Pharmacological Treatment for Schizophrenia Compared to Treatment as Usual in Subjects Who Had a First-time Treatment Failure on Their First-line Treatment.

Schizophrenia (SZ) affects approximately 4.5 million people across the European Union (EU) and is associated with annual healthcare and societal costs of 29 billion Euros. The impact on the daily life of patients is huge, ranging from frequent relapses and hospitalisations, the inability to maintain a job or continue scholing, to a low quality of life, impaired cognitive functioning, suicidal ideation and an increase morbidity rate, next to the large burden for carers 1. When diagnosed with schizophrenia or related disorder, patients are commonly prescribed antipsychotics. One-third of the schizophrenia patients are regarded treatment-resistant (TR), meaning that at least two antipsychotic trials have failed. Typically, clozapine is prescribed for TR patients, which is effective for approximately 40% of patients. Clozapine is among the most effective treatments, with the lowest all-cause mortality. Although it is among the most effective antipsychotics, it is generally not used earlier in the illness course due to a small risk of severe neutropenia/agranulocytosis, which is why patients treated with clozapine are intensely monitored. However, this small risk outweighs the burden of not receiving an effective treatment. Since clozapine is among the most effective treatments, this leads to the research question whether earlier initiation of third-line treatment ('early intensified' pharmacological treatment; EIPT) would be more beneficial than the current second-line treatments (treatment as usual; TAU). If this is indeed the case, this could lead to the prevention of unnecessary trials of ineffective treatments, hospitalisations, and recommendations for adaptations of worldwide guidelines as well as a reduction of healthcare and societal costs The INTENSIFY-Schizophrenia trial is part of the larger Horizon 2021 project Psych-STRATA, with the central goal of paving the way for a shift towards a treatment decision-making process tailored for the individual at risk for treatment resistance. To that end, the inestigators aim to establish evidence-based criteria to make decisions of early intense treatment in individuals at risk for treatment resistance across the major psychiatric disorders of schizophrenia, bipolar disorder and major depression. The current protocol focuses on the sample of schizophrenia patients.

MitoQ for Early-phase Schizophrenia-spectrum Disorder and Mitochondrial Dysfunction

The goal of this double-blind, placebo-controlled randomized clinical trial is to test the effect of 12 weeks of orally administered MitoQ (mitoquinol mesylate) supplementation on cognition in 50 people with early phase schizophrenia-spectrum disorders (E-SSD) who have mitochondrial dysfunction (called high risk, or HR). Cognitive impairments in SSD can cause significant disability. Yet, there are no effective treatments for cognitive impairments in SSD. It has been shown that alterations in a certain type of brain cell (parvalbumin interneurons, or PVI) underlie cognitive deficits in SSD. These PVI, which fire at a fast rate, utilize high amounts of energy from the mitochondria and are highly vulnerable to oxidative stress. MitoQ is an antioxidant. Research has shown that, in mice, MitoQ can reduce oxidative stress in the mitochondria. The main question that this clinical trial aims to answer is: • Does MitoQ supplementation, compared to placebo, improve cognition in HR patients? Secondary questions that this clinical trial aims to answer are the following: Does MitoQ supplementation, compared to placebo: * Improve positive and negative symptoms of SSD in HR patients? * Improve functioning in HR patients? * Improve/normalize blood markers of mitochondrial dysfunction in HR patients? The investigators will enroll 100 individuals with E-SSD. These enrolled participants will participate in an initial screening visit to determine if they qualify for the actual clinical trial. At the screening visit, the investigators will ask about psychiatric history to determine diagnosis; ask about medical history; do a physical exam; collect blood and urine samples; do a pregnancy test; and ask participants to bring in their current medications in their original packaging so it is known what they are taking. After the screening visit, the investigators will invite 50 HR patients (identified with a blood test) to continue with the clinical trial. Participants who qualify for the clinical trial will be asked to: * Take a supplement (MitoQ or placebo) once per day for 12 weeks in addition to their usual medications. * Come in for a study visit every 4 weeks over the 16-week study period. At these study visits, the investigators will do a physical exam; ask about symptoms and side effects; take blood and urine samples; and ask questions about general health and well-being, quality of life, mental health, emotional health, and mood. At visits 1 (baseline) and 4 (12 weeks), participants will also take a cognitive assessment.

Tele-group Cognitive Behavioural Family Intervention for Individuals With Schizophrenia and Their Families

This mixed-method study comprises a RCT with a twelve-week post-intervention follow-up and focus group interviews. The RCT study aims to examine the effectiveness of delivering the tgCBFI programme to dyads of people with schizophrenia and their family caregivers, while the focus group interviews aim to qualitatively study the benefits of the tgCBFI programme from the service users and their family caregivers to provide a more in-depth understanding and complement the quantitative data. The main questions it aims to answer are: Does this online tgCBFI programme reduce the expressed emotion experienced and positive and negative symptoms of individuals with schizophrenia? Does this online tgCBFI programme reduce the perceived care burden and level of mood disturbances of family caregivers?

Alternative Stimulation Mode and Location for Auditory Hallucination Neuromodulation Treatment

The purpose of the study is to test the hypothesis that functionally navigated repetitive TMS stimulations to the prefrontal cortex (PFC) modulate aberrant cortical electrical activities at PFC circuitry. The TMS location of the PFC site will be individually localized by the symptom-related functional connectivity between PFC and symptom related areas (such as the auditory and language processing cortex). The investigators predict that such modulation will correct abnormal activities in patients with schizophrenia, reduce symptoms, especially auditory hallucination, and improve working memory/sustained attention performance.

Real-life Assessment of Abilify Maintena + Rexult in Schizophrenia

MainRexult study aims to carefully evaluate a cohort of patients with schizophrenia and related disorder prescribed with the combination therapy with Abilify Maintena and Rexulti on its efficacy and tolerability in a real-life clinical setting.

Ketogenic Metabolic Therapy in Schizophrenia, Bipolar Disorder, Major Depressive Disorder: Deep Omic Profiling

The goal of this randomized clinical trial is to be adequately powered to evaluate the effect of ketogenic metabolic therapy on the quality of life in serious mental illness, schizophrenia, bipolar disorder, major depressive disorder.

A Trial of Extended Reality Activities to Enhance Leisure Participation Among Inpatients With Persistent Mental Health Conditions

The goal of this clinical trial is to evaluate the effects of an extended reality (XR)-enhanced occupational therapy leisure intervention on motivation, emotional engagement, and therapeutic participation among inpatients with chronic psychiatric conditions. The main questions it aims to answer are: Can the XR intervention improve leisure motivation, leisure-related attitudes, and emotional coping strategies in long-term hospitalized individuals with mental illness? Does the XR intervention promote improvements in psychological health, volition, and occupational performance? Researchers will compare an XR-based leisure therapy group to a usual care group engaged in standard hospital leisure activities such as art, music, or reading. Participants will take part in weekly 40-minute sessions for 6 weeks. The XR group will use a custom-designed mobile VR program featuring immersive 360° leisure scenarios aligned with participants' interests and functional goals. Data collection includes standardized assessments (e.g., Interest Checklist, Volitional Questionnaire, COPM, PANSS) and semi-structured interviews to explore changes in motivation, coping, and perceived benefits.

"Extended" (Alternate Day) Antipsychotic Dosing

The study wishes to examine whether "extended" antipsychotic treatment, in this case, antipsychotic treatment every other day, is as effective as daily treatment. It is also evaluating whether there may be differences in terms of side effects. Participants will be randomly assigned to either the treatment as usual group (i.e., taking antipsychotic daily) or the extended dosing group (i.e., taking antipsychotic one day on, one day off). That means, like flipping a coin, there is a 50/50 chance that participants will continue on daily dosing of your antipsychotic or have it switched to every other day dosing. This study will last for 1 year. Participants will be evaluated at the beginning and every two weeks during the first 6 months, with visits once every 4 weeks for the final 6 months. In total, participants will make 22 visits over 52 weeks to the investigator's office. The investigators hypothesize that with ED, there will be no change in symptom severity but improvement in the frequency and severity of side effects, wellbeing, and functioning.

Avatar-mediated Therapy Versus Cognitive Behavioural Therapy for Persisting Experiences of Hearing Voices

The aim of this study is to compare the effects of a new psychological therapy, Avatar Therapy, to the current standard therapy, Cognitive Behavioural Therapy (CBT), in improving outcomes in people living with psychotic disorders who have persisting experiences of hearing voices (auditory verbal hallucinations, AVHs).

Semantic and Syntactic Computerized Analysis of Free Speech

Subtle speech disorganization could be predictive of a transition to schizophrenia of ultra-high-risk patients. The aim of our longitudinal multicenter cohort study is to identify specific linguistic markers of the psychotic transition to validate a french predictive model of this transition using computerized speech analysis techniques
