Active clinical trials for "Psychotic Disorders"

Practicing mindfulness is popular and well-accepted for its benefits in improving mental and physical health. In particular, its benefits in promoting resilience to stress and well-being have been shown in studies involving different psychiatric conditions, as well as preventing relapse in patients with depressive disorders. However, its role in relapse prevention among patients with psychosis has not been tested. The investigators therefore propose a multi-site, single-blind, 12-month randomized controlled trial in Hong Kong to examine the effectiveness of mindfulness intervention in prevention of relapse among 152 remitted psychosis patients.

This application seeks to determine if neurophysiological metrics of memantine (MEM)-enhanced early auditory information processing (EAIP) in schizophrenia (SZ) mediate gains in auditory processing fidelity (APF) and auditory learning.

Social impairment is one of the core symptoms in first episode psychosis (FEP). Despite negative symptoms and social cognition impairment found in patient suffering from FEP, clinicians occasionally identified socially inappropriate behaviours (SIB) after onset and stabilization of psychotic disorder. It is also uncommon that some caregivers often complain about their relatives with psychosis of embarrassing and immature behaviour. SIB mainly observed in form of excessive emotional expression, childish behaviour and regressive behaviour. There is limited research focusing on this inadequate behavioural pattern in patient with first episode psychosis recently. It was worth investigating this phenomenon and gain more understanding in other comorbidity symptoms and caregiving distress arisen from this. Psychometric tests and validated assessment tools are well-developed for measuring positive symptoms, negative symptoms, neurocognitive deficits and social cognition impairment in schizophrenic patients but none of them is useful specifically for assessing SIB, and not to mention, from carer's perspective. It could be an obstacle for clinicians to investigate the phenomena of the prevalence and the impact on family in real life without any validated assessment tools or questionnaires. This qualitative study aims to identify the SIB in patients with FEP and to explore the caregiving experience and distress. Hopefully, this study may help designing a questionnaire for future exploration on this topic.

This study investigates whether Introspective Accuracy (IA) can be improved in individuals with schizophrenia by stimulating the brain via transcranial Direct Current Stimulation (tDCS).

This study aims to estimate the effect of a 3-month High Intensity Interval Training on antipsychotic-induced weight gain in patients with a first episode of psychosis, as well as to determine whether these effects are maintained 9 months after the intervention has ended.

This is a single-blind randomized within-subject crossover design study that will be conducted in 2 phases. In Phase 1, up to 50 participants, after signing informed consent and determining eligibility, will undergo a baseline EEG and cognitive assessment. In Phase 2 participants will undergo tACS at IAF+2Hz, IAF-2Hz, and IAF during a double-flash illusion task in a randomized order. The tACS will be applied with a current of 1-2 mA (milliamperes) via two saline soaked electrode sponges (25 cm²) applied to the back of the head. The investigator's hypothesis is that participant's will perform better on the visual task while tACS is set to 2 Hz above their IAPF, relative to tACS set to 2 Hz below their IAPF.

The purpose of this mixed methods study is to evaluate a peer-delivered decision support intervention with emerging adults newly enrolled in an early intervention program, also known as coordinated specialty care (CSC). It is hypothesized that participants will experience a reduction in decision-making needs after participating in the intervention, and that study and intervention procedures will demonstrate feasibility and acceptability.

Psychotic disorders are often chronic conditions that lead to impaired functioning, quality of life and social integration. Current research and recommendations for good practice are moving towards early detection and intervention. It is recognized that this leads to better adherence, alliance to care and knowledge of pathology for the patient, especially in young patients. For more than a decade, early intervention services (EIS) are opened in France over an increasingly large territory. Still too few studies assess the impact of these structures in France. These EIS offer a multimodal intervention (social, professional, psychotherapeutic). The intervention of case managers (or care coordinators in french) seems to be the core of EIS. The case manager has a fundamental role in the process of recovery in coordinating each individual's treatment and ensuring continuity of care. The PEPsy-CM study aims to evaluate the effectiveness on the relapse rate of a 3 year Program for Early Psychosis based on Case Management (PEPsy-CM) compared to TAU in a population of young people with a FEP. A qualitative evaluation of case management practice in EIS seems essential to assess the impact of case managers under real conditions. Based on the Australian Good Practice Recommendations (EPICC integrity tools) and the case management practice manuals, the PEPsy-CM check-list questionnaire was developed to evaluate the practice of case management in the EIS in France. This check-list contains different 35 items. The final score between 1(poor) to 5 (good) is established to determine the quality of the case management. Qualitative data are also collected during the interview with the participants.

This is a pilot study. We are testing the physiologic, immune and chemical responses to stress. We believe the results of all measures to stress will be blunted in schizophrenia compared to healthy controls. We will test sex, early life stress and other factors on the relationship to a stress response.

This study assess the safety and effects of atypical antipsychotics in subjects with psychosis syndrome and psychosis risk syndrome.
