Schizophrenia Spectrum and Other Psychotic Disorders

The objective of this study is to respond to frequent requests from patients who wish to reduce or even stop their antipsychotic treatment once they have achieved clinical stability. Psychiatrists are reluctant to respond to these requests because the method for safely reducing or stopping antipsychotic treatment remains poorly understood. The investigators want to verify the existence of an interaction between treatment strategy and psychotic phenotype (cycloid psychosis vs. non-CP), i.e., in terms of functional remission, the benefit of the dose reduction strategy compared to the maintenance strategy will be greater in the CP group than in the non-CP group. To this end, patients will be randomly assigned to four groups based on their phenotype and treatment strategy (CP-dose reduction; CP-dose maintenance; non-CP-dose reduction; and non-CP-dose maintenance). Several hospitals throughout France are participating in this study, in which a random draw (called randomization) will be conducted to determine whether the physician will propose reducing the antipsychotic dose or maintaining it at the same dose for the patient. Patients included in this study will be adults aged 18 to 60 who have been diagnosed with a schizophrenic spectrum disorder (SS): schizophrenia, schizophreniform disorder, schizoaffective disorder, or brief psychotic episode. The antipsychotics studied are: * second-generation antipsychotics: amisulpride, aripiprazole, olanzapine, quetiapine, risperidone; * first-generation antipsychotics: chlorpromazine, flupentixol, haloperidol, levomepromazine, loxapine, pipotiazine, zuclopenthixol. 288 patients will be included and followed for 24 months. The inclusion period is 48 months. Fourteen follow-up visits are planned, every month for four months and then every two months. During these visits, self-questionnaires or cognitive tests will have to be completed by the patient, the caregiver, and/or the treating psychiatrist. Three blood samples will be taken at inclusion, at 6 months, and at the end of the study, in particular to measure the level of medication in the blood.

The Biomarkers/Biotypes, Course of Early Psychosis and Specialty Services (BICEPS) study aims to understand the early stages of psychotic disorders like Schizophrenia, Schizoaffective Disorder, and Bipolar I Disorder. It involves gathering mental health information, brain scans (MRI), eye movement patterns (Eye-Tracking), and brain electrical waves (EEG) data from individuals who have experienced these disorders in recent years. Participants will be involved for about a year, with four visits over this period. Screening procedures, lasting approximately 3 hours, include tests for drug use, a pregnancy test for eligible women, clinical interviews about feelings and experiences, psychiatric and family history interviews, and a medical history review. Research procedures for eligible participants include DNA collection, a neuropsychological test battery, EEG, eye-tracking, and MRI. These procedures will help researchers understand brain function, genetics, and cognitive abilities related to psychotic disorders. Follow-up visits at 1-month, 6-month, and 12-month intervals involve modified clinical interviews and repeating neuropsychological tests to track changes over time. Participants may opt to provide DNA samples for genetic analysis, undergo various cognitive tests, EEG to record brain waves, eye-tracking to monitor eye movements, and MRI scans to visualize brain structure. Follow-up visits at regular intervals will help researchers track changes in symptoms and cognitive function. This study provides comprehensive insight into the onset and progression of psychotic disorders and offers valuable information for patients, families, and healthcare providers involved in managing these conditions. Our goal is to better understand whether a combination of biological markers and different types of people (BT1, BT2, BT3) can help us predict how well individuals with early psychosis respond to specialized care. We expect that those in BT3 will have the best outcomes, BT2 will have intermediate outcomes, and BT1 will have the poorest outcomes. Even though BT1 and BT2 might start with similar cognitive issues, their biology might lead to different responses to treatment. This research can help us understand which treatments work best for different people with early psychosis.

Worries about harm from others (also known as paranoia) are common. Thinking fast or going on gut feelings is natural but can fuel these worries. For some, fast thinking and worries start to get in the way of life. Cognitive behaviour therapy for psychosis (CBTp) is the recommended talking therapy. However, only a minority of people can access CBTp due to limited resources, and even when available, therapy can be difficult to do and use in daily life. SloMo is a digitally supported therapy that aims to overcome these barriers, and was developed by people with psychosis, designers, and psychologists. It supports people to notice worries and fast thinking habits. During therapy sessions, people learn to slow down and feel safer. Personalised spinning thought bubbles are slowed down using SloMo tips. An app provides access to helpful messages. SloMo was previously tested in a randomised trial of 361 people attending mental health services. SloMo was found to be safe to use, with no adverse events linked to the software. People in the SloMo group had lower paranoia, and better confidence and wellbeing, over 6 months compared to people who just received their usual care. People found SloMo enjoyable and easy to use. The next step is to evaluate if SloMo can be safely and effectively delivered by therapists working in NHS services. If SloMo works in routine care, the therapy will be made more widely available in the NHS. An improved version of SloMo has been co-produced based on feedback. Sixty therapists will be trained and supervised in 3 trusts to deliver SloMo to 150 people who fear harm from others. Safety, technical performance, uptake, engagement and acceptability data, alongside interviews with patients, therapists, and managers, will investigate how SloMo is used. Paranoia severity and wellbeing will be measured pre, post therapy, and at 12 months follow up, to find out if SloMo helps. Service use data will evaluate costs and savings.

This study will examine the effectiveness of a Pragmatic, Metabolic Care Clinic for Patients With Severe Mental Illness

Schizophrenia is a severe mental illness that seriously affects the health and functioning of patients. Previous studies have found immunoinflammatory abnormalities in the blood, cerebrospinal fluid, central nervous system, and neuroimaging of people with schizophrenia, along with therapeutic effects of anti-inflammatory drugs on schizophrenia. These evidences suggest a close relationship between schizophrenia and immunity and inflammation. Therefore, we consider that the state of immune inflammation is a potential subtype classification basis for schizophrenia, and hypothesize that immune classification based on peripheral-central multidimensional data is related to patient's response to medication and cognition.

The term sexual (SD) dysfunction covers conditions that prevent people from having a satisfactory sex life. SD is a frequent and sometimes debilitating complication of mental illness and a known adverse reaction to psycho-pharmacological treatment. SD is also associated with diabetes, a common somatic comorbidity in psychiatric patients. SD is associated with both reduced quality-of-life and reduced treatment adherence, yet SD is far too rarely addressed between the patient and the healthcare professional in clinical consultations. The purpose of the study is to investigate whether targeted education of patients with schizophrenia and diabetes/prediabetes and/or their healthcare professionals in causes and management of SD: * Increases the number of systematic examinations of sexual side effects, * Causes changes in the psycho-pharmacological treatment, and * Reduces the severity or perception of sexual side effects. The study is a multicenter Randomized Controlled Trial (RCT) with four arms, in which the educational intervention is provided to patients, healthcare professionals, or both groups. The effect of the educational intervention is compared to a non-educated control group. The study is expected to include 192 patients recruited from 16 assertive community treatment centers evenly distributed in four Danish regions. The study is part of an interdisciplinary project named SECRET. The educational intervention was developed in an ethnographic pre-study incorporating stakeholder engagement. Parallel to the present RCT, an ethnographic field study will be carried out to broaden the perspective on the effects of the intervention.

The main aim of the clinical trial is to validate the Machin Learning (ML) predictive model for personalized Metacognitive Training (MCT) by comparing classic MCT to personalized MCT (P-MCT) among patients diagnosed with psychosis who had a history of delusions. More precisely, we will compare classic MCT to P-MCT in a randomized clinical trial.We expect personalised MCT treatment will see more improvement than classical MCT in outcome variables measuring treatment efficacy.

The primary aim of this study is to evaluate the safety and efficacy of AVATAR therapy, developed to address residual auditory hallucinations persisting despite medication in schizophrenia spectrum disorder. The intervention aims to reduce the intensity and frequency of these symptoms, as well as alleviate associated depressive and anxiety symptoms, using a virtual reality (VR)-assisted intervention developed for this purpose by the Danish company HEKA VR. The study will be a pre-post non-invasive, waiting list-controlled study, enrolling 30 patients from three clinical sites (Hungary, Spain, Poland). The study centers around administering therapy based on VR over a 12-week period, comprising a total of 7 sessions. These sessions are conducted individually and last 50 minutes each. The psychotherapist leading the sessions adheres to a strict protocol defined by the method's developers. During the intervention, VR technology is used to simulate the source of distressing auditory hallucinations. The therapist facilitates coping with these experiences externalized in this way through simulated conversations, supporting the development of more adaptive responses. Patients undergo a comprehensive cross-sectional evaluation of their condition before and after the intervention, including assessments of symptom severity, quality of life, and their experience with the method. The intervention is conducted with constant monitoring for possible adverse effects.
