Filter by:Schizophrenia is one of the most severe and costliest mental disorders in terms of human suffering and societal expenditure. About 15-30% of patients do not respond to all known antipsychotics, including clozapine, the current gold-standard in these cases. Hence, a recent Cochrane review stated that the quality of the existing studies is too poor to recommend any intervention in addition to clozapine and that new, randomized controlled trials independent from the pharmaceutical industry need to be performed to substantially improve patient care. Although electroconvulsive therapy (ECT) was initially used to treat schizophrenia, it is nowadays by far underused in the therapy of schizophrenia in many countries. ECT is well known to be highly effective in clozapine-treatment-resistant schizophrenia (CRS), and synergistic effects of clozapine and ECT have been demonstrated. However, relapse rates after successful courses of ECT are still very high, and evidence for maintenance ECT (mECT) in CRS is scarce at best. In a multi-center trial the investigators aim to examine the effectiveness of mECT in treatment-resistant patients with schizophrenia who improved after a course of routine ECT. If mECT will lead to a later timepoint of relapse and/or to a higher proportion of relapse-free patients compared to those undergoing treatment as usual, this trial would have an enormous impact on therapeutic strategies for "treatment-resistant" patients and would induce a profound change of current treatment guidelines, where ECT still ranks at the level of ultima ratio, despite accumulating evidence suggesting otherwise.
Study group: Experimental study to evaluate empathy, compassion, and nature connectedness before and after an immersive virtual reality experience in patients with depressive disorder, patients with psychotic disorder and healthy control subjects (subjects between 18 and 65 years of age). Primary hypothesis: The increase in nature connectedness explored by virtual body ownership of a tree in VR differs depending on the health condition (schizophrenia, depression, healthy controls).
This Phase 2 study described herein will evaluate the safety, efficacy, tolerability, and pharmacodynamics of SPG302 in adults with a primary diagnosis of schizophrenia.
This study aims to explore the health effects of group games for patients with chronic mental illness. The goal of this clinical intervention study is to compare the efficacy of group games in two ways (experimental group/ group game-based or control group) to improve the health of patients with chronic mental illness. The main questions it aims to answer are: The efficacy of applying group game-based activities to increase interest and improve the physical fitness of patients with chronic mental illness. Also, the goal of this clinical interventional study is to clarify the positive benefits of psychological and social aspects. Subjects will be asked to complete the questionnaire and physical ability examination after filling out the consent of this study. Participants will be randomly divided into two groups. Participants in the experimental group will accept the group game-based activities for 12 weeks (twice per week, 22 times). In contrast, Participants in the control group will accept the activities the psychiatric day wards and halfway house offer as usual. After 12 weeks of intervention, The Participants in both groups will be asked to fill out the questionnaire and physical ability examination. One month later, Participants in both groups will be asked to fill out the questionnaire and physical ability examination again. The study will last for 4 months. The time points for completing the questionnaire are listed following: Baseline/ pre-intervention test(T1), First post-intervention test (T2, 12 weeks later) and Second post-intervention test (T3, 4 weeks later). The researchers will compare the difference in effectiveness between the two groups.
The objective of this study is to recruit patients at the first diagnosis with a schizophrenia spectrum disorder (SSD) and ultra-high risk patients (UHR), defined as patients with drug abuse and psychotic symptoms indicating a risk for developing schizophrenia. Thereby, the investigators aim to establish a large representative cohort of patients with a first-episode SSD or patients at UHR, enabling investigations of the etiology and long-term prognosis of SSDs. The primary aim is to learn more about the importance of adverse childhood experiences (ACEs) and the immune system in the etiology and course of schizophrenia. Patients will be followed with planned visits after 1, 2, 3, 12 and 24 months including online questionnaires after 2, 6, 10 and 26 weeks. There will be the possibility to contact patients again for subsequent follow-up visits.
The goal of this clinical trial is to learn if a ketone drink can improve signs and symptoms of patients with a schizophrenia-spectrum disorder (SSD), or a bipolar-spectrum disorder (BD). The main questions it aims to answer are: Does a ketone drink improve information processing in patients with SSD/BD? Other questions it aims to answer are: Does a ketone drink improve cognitive functioning in patients with SSD/BD? Does a ketone drink improve metabolism and inflammation in patients with SSD/BD? Research will compare the effects of the ketone drink with that of an isocaloric carbohydrate drink in the same patients ('cross-over'). Participants will: 1. drink a ketone drink and (after a wash-out period) an isocaloric control drink; after each drink: - EEG to determine information-processing parameters (PPI and P300) - cognitive tests - visual analog scale of mood, energy levels, ability to focus - indirect calorimetry to determine use of energy substrate - blood draws 2. for 5 consecutive days: - wear a continuous glucose monitor (CGM) - wear a non-invasive passive sweat biomarker sensor (EnLiSense device) - register a diet and nicotine diary - saliva sampling (max. 4x/day, only on both intervention days)
The goal of this clinical trial is to compare the efficacy of combined REHACOP + MCT alone in persons with nonaffective psychotic disorder in terms of recovery. The main questions it aims to answer are: - Does combined REHACOP + MCT therapy increase the clinical recovery in persons with nonaffective psychotic disorder (compared to MCT alone)? - What is the impact of combined REHACOP + MCT therapy compared to MCT therapy alone on personal/psychological recovery, cognitive biases, and social cognition, taking gender differences into account? - What is the durability of the effects of combined REHACOP + MCT therapy compared to MCT therapy alone on clinical recovery, personal recovery, cognitive biases, and social cognition in the long term? Researchers will compare REHACOP+MCT therapy to MCT alone to see if there are differences in personal/psychological recovery. Participants will: - Participate in Metacognitive Training or in combined REHACOP + Metacognitive training therapy. - Do 8 weekly sessions of 45-60 minutes (MCT group). - Do 12 weekly sessions of 45-60 minutes (RECHACOP+MCT group). - Visit the clinic for checkups and tests. - Answer self-administered tests.
The CLIMATE-II Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, degree of urbanisation of the patients' administration district and characteristics of the patients' neighborhood are associated with these effects.
The goal of this experimental prospective study is to build an explicative model of trait fatigue in adults with schizophrenia engaged in a psychosocial rehabilitation process. The main questions it aims to answer are: - Which factors amongst those evaluated explain the most of fatigue variance in people with schizophrenia? - Which clinical factors characterise the most fatigued participants compared to less fatigued participants? Participants will wear an accelerometer for seven days to assess their sedentary and physical activity behaviours as well as their sleep. After this, they will undergo an experimental visit, to asses: - Fatigue - Cognitive function - Tobacco and caffeine consumption - Fatigue catastrophizing - Sleep quality - Sarcopenia risk - Functional capacities - Handgrip strength - Quadriceps maximal strength and fatigability
The goal of this clinical trial is to compare two active types of transcranial magnetic stimulation in two nicotine-using populations: nicotine-using people with psychosis and nicotine-using people without a diagnosis of a psychotic disorder. The main questions it aims to answer are: 1. Can rTMS change functional connectivity in brain circuits associated with nicotine use? 2. Are those rTMS-induced changes in functional connectivity related to craving? Participants will complete tasks assessing their cognitive performance and craving before and after each week of TMS. Researchers will compare the effect of each TMS intervention on participants with and without psychosis to see if one type of TMS has an effect on nicotine craving.
