Brain Imaging of Childhood Onset Psychiatric Disorders, Endocrine Disorders and Healthy Volunteers...
Attention Deficit Hyperactivity DisorderSchizophrenia1 moreMagnetic Resonance Imaging (MRI) unlike X-rays and CT-scans does not use radiation to create a picture. MRI use as the name implies, magnetism to create pictures with excellent anatomical resolution. Functional MRIs are diagnostic tests that allow doctors to not only view anatomy, but physiology and function. It is for these reasons that MRIs are excellent methods for studying the brain. In this study, researchers will use MRI to assess brain anatomy and function in X and Y chromosome variation, healthy volunteers, and patients with a variety of childhood onset psychiatric disorders. The disorders include attention deficit disorder, autism, congenital adrenal hyperplasia, childhood-onset schizophrenia, dyslexia, obsessive compulsive disorder, Sydenham's chorea, and Tourette's syndrome. Results of the MRIs showing the anatomy of the brain and brain function will be compared across age, sex (gender), and diagnostic groups. Correlations between brain and behavioral measures will be examined for normal and clinical populations.

Horyzons: Implementation and Integration in Clinical Practice
SchizophreniaSchizophreniform Disorders2 moreThe primary aim of this trial is evaluating the barriers and enablers of implementing a digital intervention with both therapeutic content and social networking, Horyzons, as part of clinical care in first episode psychosis (FEP) clinics in North Carolina. Providers (clinicians and peers support specialists) will be recruited from FEP clinics to assess Horyzons implementation and integration within clinical care at three time points (baseline, 6 months, and 12 months). Further, individuals experiencing FEP between the ages of 16 and 35 receiving services from the FEP clinics will be recruited to engage with the platform over the course of 12 months. Due to the nature of the digital intervention being implemented across the state of North Carolina, all research visits will be conducted remotely via videoconferencing.
PhaRmacOgenetics and Therapeutic Drug Monitoring In SchizophrEnia
Patients With SchizophreniaSchizophrenia is a severe chronic mental disorder with a long-term treatment. Most antipsychotic (AP) drugs are effective for only 30% to 60% of patients and for many drugs, treatment selection remains a "trial-and-error" process.The main result of treatment inefficiency is relapse, the recurrence of acute symptoms after a period of partial or complete remission. Pharmacogenetics (PG) is the study of genetic differences in drug met-abolic pathways which can affect individual responses to drugs, both in terms of therapeutic effect as well as adverse effects. PG testing could therefore identify patients at potentially high risk of relapse allowing the opportunity of an individualized prescription. In this study, PG was shown to improve the safety profile of AP treatments in patients presenting PM or UM CYP variants, by reducing associated side effects. Therapeutic Drug Monitoring (TDM) is the quantification and interpretation of drug concentration in blood to optimize pharmacotherapy . For drugs with established therapeutic reference ranges (TRR) or with a narrow therapeutic index, it makes sense to measure drug concentrations in blood for dose titration after initial prescription or after dose change. Non adherence is a recurrent problem in the management of schizophrenia, leading to reduced quality of life and increased risk of relapse. TDM is recognized as a direct reliable measure for drug adherence and can be an additional support after a therapy adjustment. Additionally, TDM can be useful to educate patients and make them more aware of their treatment. Finally, TDM is likely to ensure a better tolerance and fewer side effects for APs, while allowing a better efficacy. However, evidence on the clinical impact of this tool in schizophrenic population is lacking and randomized clinical trials are needed to confirm it. Finally, relapses occur frequently in schizophrenia and the cost for a relapsing schizophrenic patient is estimate over 4 times higher than for a non-relapsing patient, highlighting the importance of cost-effective care strategies. When separately used PG testing or TDM alone, might not be sufficient to ensure the clinical utility and cost-effectiveness of these tests. We hypothesize that individualized medicine including the association of PG testing with TDM (PG/TDM intervention), on the most commonly prescribed AP drugs, can reduce relapse rate at one year while being cost-effective.
Empagliflozin Addition in Modulating Metabolic Disturbances Associated With Olanzapine in Schizophrenia...
Sodium-glucose Transport Protein Two Inhibitor (SGLT2),Metabolic Deficits Caused by AntipsychoticsOlanzapine is a thieno-benzodiazepine derivate that is effective managing the symptoms of schizophrenia and reducing the psychopathological symptoms of psychosis. It is also effective in controlling the acute manic episodes associated with bipolar disorder, and have provided some therapeutic advantages over other antipsychotic agents (Citrome et al., 2019). However, Ola administration has been reported to induce profound BWG accompanied with higher incidence of metabolic deficits, such as hypertension, diabetes and hyperlipidemia, as compared to other antipsychotic agents (Mauri et al., 2014). Adjunctive treatment with other agents that can minimize or normalize Ola-induced BWG can enhance the safety and tolerability profiles of an effective antipsychotic, thus highlighting the need to develop improved therapies or interventions to minimize these side effects. A meta-analysis of 12 published studies found that antidiabetic drugs such as metformin improved metabolic parameters in patients treated with antipsychotics (de Silva et al., 2016). These studies encouraged the evaluation of other antidiabetic agents as adjunctive therapies to minimize Ola-induced BWG. Empagliflozin (EMPA)is the third-generation anti-diabetic drug acting as sodium-glucose transport protein two inhibitor (SGLT2), which provides a new mechanism of action to improve glycemic control with modest decreases in systolic blood pressure and body weight (Pradhan et al., 2019). The effects of EMPA on Ola-induced BWG have not been determined and require further investigation.
The Effect of a Six Week Intensified Pharmacological Treatment for Schizophrenia Compared to Treatment...
Schizophrenia and Related DisordersEarly Treatment-ResistanceSchizophrenia (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.
Cognitive Effects of Adjuvant Vortioxetine in Early Schizophrenia
Cognitive Impairment With Primary Psychotic DisorderNegative Symptoms With Primary Psychotic DisorderClinical trial to assess the efficacy of Vortioxetine compared with treatment as usual in early schizophrenia.
Effects of Auditory Stimulation on Sleep and Memory in Schizophrenia
SchizophreniaThe investigators will test the hypothesis that auditory stimulation (playing quiet sounds during sleep) can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by measuring sleep and memory performance under two conditions separated by one week: receiving auditory stimulation during sleep and not receiving auditory stimulation during sleep. The investigators will study healthy subjects and outpatients with schizophrenia.
fMRI-based Neurofeedback to Relieve Drug-resistant Auditory Hallucinations
SchizophreniaHallucinations3 moreThe INTRUDE trial aims at assessing the efficacy of an fMRI-based neurofeedback procedure on drug-resistant auditory hallucinations. Hallucinations are complex and transient mental states associated with subtle and brain-wide patterns of activity for which we were recently able to validate an fMRI multivariate decoder. Based on this progress, we can track patients' hallucinatory status using real-time fMRI. We will test whether schizophrenia patients with drug-resistant hallucinations can be trained to maintain the brain state associated with a no-hallucination condition using appropriate strategies and thus reduce overall severity. We will refer to a double-blind randomized placebo-controlled design. A total of 86 patients will be enrolled and equally split in an active neurofeedback group (n=43) and a sham group (n=43), matched for sex, age and PANSS scores. Each patient will benefit from 4 runs of either active or sham neurofeedback. The primary outcome measure will be the mean decrease of AHRS scores relative to baseline, and at 1 month post-treatment. We expect significant clinical benefits from fMRI-based neurofeedback on drug-resistant hallucinations compared with the sham group.
Non-Pharmacological Treatment of Psychosis
Psychosis; Schizophrenia-LikeThe objectives of the project are to investigate feasibility, safety, and health-related outcomes in patients with psychosis who choose not to use antipsychotic drugs (APs). The instruction from the Ministry of Health and Care Services to establish "Medication Free" (non-pharmacological (NonPharm)) treatment services, which has received substantial critique for being given without support in scientific evidence, provides a window of opportunity for research in an under-investigated field. The study will prospectively follow a cohort over 1 year who seeks NonPharm treatment, with repeated measurements of symptoms, functional outcomes, quality of life, adverse events, as well as biological parameters including genetics and brain imaging, and environmental factors, and compare the findings to a control group of users of antipsychotic drugs, matched for age, gender and diagnosis. Current unanswered questions in the treatment of psychosis include which patients can successfully and safely discontinue antipsychotic medication; and what are the long-term symptomatic, biological and functional outcomes after use or non-use of APs, respectively. Taken together there is a fundamental lack of high-quality evidence to guide the treatment options in people who cannot or do not want to use APs in psychosis. This is also a major challenge in the study, as a more rigorous design that could directly compare different treatment options is not feasible, because no alternatives to APs have proven to be sufficiently effective and safe in controlled trials. The study is accordingly expected to provide new exploratory information that could be the basis of intervention studies which in its turn could provide important information for consumers and the mental health services regarding treatment options in psychosis.
