Filter by:A randomized crossover trial of ALAN intervention was conducted in patients with chronic schizophrenia in Anhui Mental Health Center from August 15 to September 30, 2022. All participants met the diagnostic criteria for schizophrenia in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). The enrolled patients were in the symptom-stable phase and were regularly prescribed antipsychotics (no change in medication regimen). The diets of all the participants were uniformly supplied during study. Patients with infectious diseases, eye diseases, or gastrointestinal diseases, or who used antibiotics at the time of recruitment, were excluded. The wards of the participants were all located in the same inpatient building. All included wards had the same size, layout, lighting and orientation of doors and windows. In normal conditions, each ward retains a small LED lamp (the same layout in all wards) at night as a source of lighting. The study was divided into two stages. In the first stage, 10 wards were randomly selected as the intervention group (opaque black tape covering part of the light source), and another 10 wards were selected as the control group (no intervention). After a two-week washout interval, the second stage was carried out, with the two groups interchanging interventions. At the end of each intervention, participants completed a structured questionnaire scale to assess the relapse risk of schizophrenia, and then their fecal samples were collected.
This prospective longitudinal cohort study will follow patients with schizophrenia who are treated with second generation long-acting injectable antipsychotic medications (LAIs) for 48 weeks to determine the risk of psychotic symptom relapse when treatment adherence is established. The study is designed to minimize the other factors that have contributed to breakthrough psychotic symptoms in patients treated with LAIs including poor adherence, substance use, concurrent mood disorders, poor treatment response, failed cross-titration, and insufficient dosing. Eligible subjects will undergo a screening visit to document that inclusion criteria are met and those meeting exclusion criteria are excluded. Participants will be assessed every 12 weeks to determine whether they remain in remission or meet criteria for a relapse. More comprehensive assessment will be completed at the beginning of the study (baseline visit), at the 24-week study midpoint and the 48-week study endpoint. Plasma antipsychotic levels will be measured at these three study time points to investigate associations between plasma levels and remission/relapse status as well as side effects. Plasma prolactin will also be measured to assess the association with sexual side effects. Hemoglobin A1c and measures of total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol will be obtained to assess the effects of SGA LAIs on these measures.
About 1 in 100 people will experience an episode of psychosis. Some people will only experience one 'psychotic episode' and about a quarter of people make a full recovery. Others will have recurring periods of problems ('relapses'), perhaps at times of particular stress. As people often find psychosis distressing, this study looks at ways to help them stay well in the future. There is growing evidence that 'early signs' interventions can prevent relapses of psychosis. Early signs are things that might happen when people start to become unwell. For example some people start to sleep badly when they are becoming unwell. Most people with psychosis can identify early signs emerging in the weeks before relapse. In early signs interventions, service users are taught to recognise early signs that their mental health may be deteriorating so that they can take action to avoid becoming unwell. Although early signs interventions show promise, the investigators suggest that they can be improved by more accurate assessment of relapse risk. This might be achieved by monitoring 'basic symptoms' in addition to conventional early signs of relapse. Basic symptoms are subtle, subclinical disturbances in one's experience of oneself and the world. Typical basic symptoms include: changes in perceptions, such as increased vividness of colour visionÍž impaired tolerance to certain stressorsÍž difficulty finding or understanding common words. In this study the investigators want to design and test a mobile phone app to help monitor basic symptoms. They hope that the app might help service users to stay well in the future. During the study the investigators will ask participants to use the app once a week for 6 months. At the end of the study they will interview them about their experiences of using the phone app and participating in the study.
This open-label, non-randomized, prospective study will evaluate the risk of symptoms recurrence during the ten years after antipsychotic discontinuation in a sample of functionally recovered first-episode patients with schizophrenia spectrum disorder.
To reduce antipsychotics to under 1000mg in patients with schizophrenia taking more than 1000mg/day and to evaluate relationship between relapse and cognitive function.
This open-label, non-randomized, prospective study will evaluate the risk of symptoms recurrence during the three years after antipsychotic discontinuation in a sample of functionally recovered first-episode patients with schizophrenia spectrum disorder.
