Filter by:Serious mental illnesses (SMI) like schizophrenia and bipolar disorder are two of the most disabling and costly chronic illnesses worldwide. A high proportion of adults with schizophrenia and bipolar disorder have sleep disorders, like obstructive sleep apnea (OSA), but tend to be underdiagnosed and undertreated compared to the general population. This study aims to examine feasibility, acceptance, and impact of OSA treatment and how it affects cognitive function in people with SMI.
Aim: 1. To confirm that patients with predominant negative symptoms in schizophrenia have deficits in frontal cortical dopamine release when compared with healthy control and patients with positive symptoms. 2. Our previous study found patients with negative symptoms have more possibilities to have disorders in glucose metabolism, we wonder whether dopamine release, negative symptoms or glucose metabolism can be improved by iTBS. Study design: Case control study.
Background: In parallel to the traditional symptomatology, deficits in cognition (memory, attention, reasoning, social functioning) contribute significantly to disability and suffering in individuals with schizophrenia. Cognitive deficits have been closely linked to alterations in early auditory processes (EAP) that occur in auditory cortical areas. Preliminary evidence indicates that cognitive deficits in schizophrenia can be improved with a reliable and safe non-invasive brain stimulation technique called tDCS (transcranial Direct Current Stimulation). However, a significant proportion of patients derive no cognitive benefits after tDCS treatment. Further, the neurobiological mechanisms of cognitive changes after tDCS have been poorly explored in trials and are thus still unclear. Method: The study is designed as a randomized, double-blind, 2-arm parallel-group, sham controlled, 4-centers trial. Sixty participants with recent-onset schizophrenia and cognitive impairment will be randomly allocated to receive either active (n=30) or sham (n=30) tDCS (20-min, 2-mA, 10 sessions during 5 consecutive weekdays). The anode will be placed over the left dorsolateral prefrontal cortex and the cathode over the left auditory cortex. Cognition, tolerance, symptoms, general outcome and EAP (measured with EEG and multimodal MRI) will be assessed prior to tDCS (baseline), after the 10 sessions, and at 1- and 3-month follow-up. The primary outcome will be the number of responders, defined as participants demonstrating a cognitive improvement ≥Z=0.5 from baseline on the MATRICS Consensus Cognitive Battery total score at 1-month follow-up. Additionally, we will measure how differences in EAP modulate individual cognitive benefits from active tDCS and whether there are changes in EAP measures in responders after active tDCS. Discussion: Besides proposing a new fronto-temporal tDCS protocol by targeting the auditory cortical areas, we aim to conduct an RCT with follow-up assessments up to 3-months and a large sample size. In addition, this study will allow identifying and assessing the value of a wide range of neurobiological EAP measures for predicting and explaining cognitive deficits improvement after tDCS. The results of this trial will constitute a step toward the use of tDCS as a therapeutic tool for the treatment of cognitive impairment in recent-onset schizophrenia.
This study aims to provide an evidence-based shared decision making intervention for antipsychotic medications, the Antipsychotic Medication Decision Aid (APM-DA), for individuals experiencing early psychosis and provide, for the first time, an understanding of the shared decision making mechanism of action.
Schizophrenia is a mental illness that progresses with delusions or hallucinations, causes changes in interpersonal communication, thoughts and behaviors, continues with recovery and repetitions, and in which the interpretation of reality is impaired. Drug treatment alone is not sufficient in schizophrenia, and it is known that negative symptoms continue even in patients with a good response to drug treatment. For this reason, complementary therapies, psychosocial approaches and rehabilitation in addition to drug therapy increase the effectiveness of the treatment.
Schizophrenia is a group of severe mental disorders of unknown etiology, with significant abnormalities in mental activities such as cognition, thinking, emotion, and behavior, and lead to obvious occupational and social function damage. At present, many studies have found that nicotine and cognitive function changes are related, and many studies have carried out a series of explorations for patients with schizophrenia, but there is no study on the mechanism of nicotine on cognitive function in patients with schizophrenia through changes in glycolipid metabolism, and this study intends to explore whether nicotine participates in the cognitive changes of patients with schizophrenia by regulating glycolipid metabolism, which is conducive to the in-depth study of the mechanism of cognitive function change in schizophrenia, in order to find an effective way to improve the cognitive function of schizophrenia.
This pilot study aims to investigate the use of MRI-guided low-intensity focused ultrasound (LIFU) to modulate neuronal activity within the thalamus in human subjects with treatment-resistant schizophrenia.
This study aims to investigate the potential beneficial effects of a medication review by a clinical pharmacologist on patients with coexisting schizophrenia and diabetes. The study is an intervention study in which an intervention group is assigned to the medication review whereas a control group is not. Both groups are tested using a thorough test battery at baseline and 6 months after inclusion. Furthermore a qualitative data assessment will be undertaken using interviews and surveys in order to show any obstacles in implementing the intervention. This is relevant as medication reviews, performed by clinical pharmacologists as well as pharmacists, are not always implemented by the primary physician.
This is a Phase Ib clinical study of TPN672 maleate in patients with schizophrenia
Schizophrenia is a chronic psychiatric illness with a heterogeneous disease course, varying from periods of symptomatic remission to relapse. Relative to the wealth of scientific data on the course of schizophrenia during the two years following the first psychotic episode, the outcome of schizophrenia patients over the first decade of their illness has been studied to a lesser degree. In this follow-up cohort study we aim to investigate the long-term outcome of schizophrenia patients who participated in the previously conducted EULAST-I clinical trial, in the first decade after being diagnosed.
