Filter by:This is a Phase 3, randomized, double-blind, parallel-group, placebo-controlled, multicenter inpatient study to examine the efficacy and safety of KarXT in adult subjects who are acutely psychotic with a Diagnostic and Statistical Manual Fifth Edition (DSM-5) diagnosis of schizophrenia. The primary objective of the study is to assess the efficacy of KarXT (a fixed combination of xanomeline 125 mg and trospium chloride 30 mg twice daily [BID]) versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a DSM-5 diagnosis of schizophrenia. The secondary objectives of the study are to evaluate improvement in disease severity and symptoms, safety and tolerability, and pharmacokinetics in adult inpatients with a DSM-5 diagnosis of schizophrenia.
Involuntary mental health care is permitted because it is believed to make people with severe mental disorders (SMD) better and prevent them from getting worse or even dying In this study we will investigate whether low levels of coercion in an area is connected with poorer outcomes in Norway. It can be assumed that too little involuntary care might lead to the opposite outcomes to those intended by the Norwegian Mental Health Act. The same law applies all over Norway, but the rate of involuntary care varies: there is up to five-fold difference between the catchment areas of the 69 Community Mental Health Centers. The investigators will estimate rates of involuntary care and adjust for age, sex, urbanity and area deprivation. The data source is the Norwegian Patients Registry, and all patients in treatment for a severe mental disorder in 2015 and their use of mental health care until 2018 will be followed. Model 1 follows all patients who were treated for a severe mental disorder in 2015. The model will test whether the rates of involuntary care in the area they live can predict the length of time to death. Model 2 follows patients with treatment for severe mental disorders that had no episode of voluntary care in 2015. The model will test whether the rate of involuntary care in their area predicts their use of mental health inpatient care in 2016 and 2017. Model 3 tests how long time patients with severe mental disorders that received only voluntary care in 2015 remain without a period of involuntary care in 2016-17, as a function of the rate of involuntary care in their area. Model 4 estimates changing the total number of patients with severe mental disorders in the catchment area in 2016-17 as a function of time and the rate of involuntary in 2015. Model 5 tests whether suicide rates for a catchment area varies as a function of its rate of involuntary care. Because suicides are rare, we will observe the variables over longer time periods, using involuntary care rates from 2015 to 2018 and suicide rates for 2015-2019. The study was evaluated by the Research Ethics Committee (ref 2018/795), who approved use of registry data, and by the Privacy Ombudsman at Akershus University Hospital (ref 2018-090).
In the last years, the imbalance between excitatory and inhibitory neuronal activity has come to the fore as a possible molecular disease mechanism of schizophrenia . Pharmacological studies have suggested different fMRI and EEG markers of that molecular dysfunction (resting state connectivity changes, auditory mismatch and steady state deficits). However, previous research is inconclusive regarding their genetic basis, their reliability, inter-individual relationship as well as disease specificity. Therefore, in this study we aim at estimating the effect sizes, test-retest-reliability and clinical correlates of the respective markers in a comparative fashion in patients with schizophrenia, their relatives and healthy control subject. To assess their molecular validity, we will assess their relationship with glutamatergic and GABAergic genotypes and cellular disease models. The proof of such a relation would give the opportunity of detecting a glutamatergic and GABAergic imbalance throughout non-invasive imaging. Furthermore, it would help deepening our understanding of the molecular pathophysiology of mental disorders which will be essential for the development of more effective drugs.
The objective of this post marketing surveillance is to further gather local data on the safety and efficacy of Brexpiprazole (RexultiTM) Film-coated Tablet in the treatment of schizophrenia and adjunctive therapy of Major Depressive Disorder.
For the present study, Investigators will examine the efficacy of active prefrontal anodal tDCS versus placebo (sham) interventions to treat WM dysfunction in schizophrenia. Investigators selected the prefrontal stimulation modality that proved most effective in enhancing high-load WM performance in single dose stimulation in healthy participants . The study employs a multi-stimulation approach, with 2 sessions per day for 5 consecutive days in the active treatment group (n=15) compared to a group that receives only sham stimulation (n=15). This preliminary approach is based upon findings of a recent study applying cathodal tDCS stimulation over left temporoparietal cortex (with left prefrontal anodal stimulation) for the treatment of persistent auditory hallucinations in schizophrenia. In a a recent study clinical benefits were maintained for at least 3 months following stimulation. In the present study, in addition to clinical outcome, researchers will evaluate whether similar improvement can be obtained with WM, EEG activity, and functional outcome (e.g., discharged from hospitalization following significant improvement or remission).
The project aims to evaluate the efficacy of a therapeutic video game that incorporates elements from metacognitive training on delusions and jumping-to-conclusions in patients with psychotic disorders.
Schizophrenia Spectrum Disorder (SSD) is the main diagnosis in subjects with mental disability. The number of disabled SSD increased yearly and might be due to the ineffective medical and rehabilitative interventions on improving cognitive and motor function. Innovative and effective training programs are needed to decrease financial burden of medical care and social welfare. Multi-tasks in real world were found to be effective in improving the sports skill of athletes and multi-tasking ability in the real world. No any study investigates in depth how the multi-tasks affect SSD patients' cognitive and motor performance. Virtual reality exergaming (VREG) is a new form of multi-tasks incorporating information technology. It has been proved as an effective intervention media for patients with SSD in the single domain of physical fitness. No study exists examining its simultaneous influence in cognition and motor performance in SSD patients. The purpose of this study is to examine the effects of different forms of multi-tasks on the cognitive and motor performance. The results of this study might be used by clinician treating patients with SSD in clinical decision making regarding to whether or not incorporating contemporary information technology in daily intervention and, furthermore, benefit the SSD more than using only the multi-task in the real world. A total of 25 patients were recruited and participated in this study. They underwent 2-stage multi-task training. The first stage training used multi-tasks in the real world; the second stage training used new forms of multi-tasks which is virtual reality video sport games conveyed by Xbox Kinect. The training in each stage last for 12 weeks and there were 2 sessions in each week. The training duration in each session was 40 minutes. All participants were measured at the following three time points: before any training begins, after the 1st stage of training and after the 2nd stage of training. The outcome measures include: upper limb motor function (measured by Box-and-Block Test), cognitive function (measured by Color Trail Test), functional mobility measured by Timed-Up-and-Go Test, and standing stability in 6 stance conditions, and voluntary center of gravity shifts during Functional Reach Test (measured by Footscan pressure measurement system).
Schizophrenia is a severe neuropsychiatric disorder of the brain and is also one of the top ten disabling diseases. A common symptom of schizophrenia (SCZ) is hearing voices inside one's heads which others do not. Despite adequate medication, SCZ patients may continue to hear voices that are often rude or unfriendly and cause distress to the patients. Transcranial direct current stimulation (tDCS) is a safe, non-invasive brain stimulation technique that reduces 'hearing voices'. However, how and why add-on tDCS works is unclear. The brain can change itself in response to its environment; this is called neuroplasticity. tDCS possibly changes the brain's environment and/or enhances the brain's ability to respond favourably to its environment. This theory will be examined here by studying changes in brain functions before and after giving tDCS to schizophrenia patients hearing voices. The aim of this study is to examine the brain's neuroplasticity potential as the biological phenomena driving treatment effects of tDCS in Schizophrenia patients with clinically significant and persistent auditory verbal hallucinations. The secondary aims are to answer whether the brain's neuroplasticity potential in schizophrenia patients can predict their responsivity to tDCS treatment for auditory verbal hallucinations, and if chronicity of illness effects tDCS treatment response. The brain's neuroplasticity potential will be examined using neuroimaging and neurophysiological techniques that give information about the integrity of the brain's signal processing efficiency, the chemical concentration of certain bio-molecules within it, and how well different areas of the brain communicate with each other. With this information, the potential role of the brain's neuroplasticity potential in facilitating treatment effects of tDCS can be better understood. With this knowledge, it could be possible personalize tDCS treatment, profile tDCS responders and non-responders based on demographic and biological factors, and prescribe tDCS at the appropriate time within the illness course for maximal benefit to the SCZ patients.
The purpose of this study is to evaluate the efficacy and safety of MK-8189 at a range of doses (8 mg, 16 mg, and 24 mg once daily) in adult participants who have an acute episode of schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria. The primary hypotheses are the following: (1) MK-8189 24 mg is superior to placebo in reducing the Week 6 mean change from baseline in Positive and Negative Syndrome Scale (PANSS) total score (2) MK-8189 16 mg is superior to placebo in reducing the Week 6 mean change from baseline in PANSS total score. With Amendment 4, enrollment was changed to approximately 500 participants with removal of the MK-8189 8 mg treatment arm. Participants enrolled before Amendment 4 that have been assigned to 8 mg MK-8189 will remain on 8 mg MK-8189 per protocol.
Based on our research background, we hypothesize that LIFUS has neuromodulation effects on brain cortex and the active LIFUS on left-DLPFC would improve negative symptoms in schizophrenia patients. It would firstly verify the safety of LIFUS on human as well. The multimodal MRI will be contributed to investigate the possible mechanism of negative symptoms.
