This project is a double blind randomized clinical trials that examines the efficacy of cerebellar non invasive stimulation for apathy improvement in patients with schizophrenia
The goal of this clinical trial is to optimize the treatment of psychomotor slowing in patients with schizophrenia using Transcranial Magnetic Stimulation (TMS). A previous randomized controlled trial indicated that inhibitory stimulation over the supplementary motor area (SMA) once daily over 3 weeks ameliorates psychomotor slowing. In this trial the investigators use a shorter inhibitory protocol called cTBS and to be applied 3 times per day. This should lead to faster treatment response and less burden to patients. The main question the investigators aim to answer are: Can the treatment with cTBS 3 times per day ameliorate psychomotor slowing in schizophrenia over one week? Participants will complete questionnaires on the first and last day of the study. Each day, participants will receive the TMS-treatment. Optionally, participants can receive a cerebral MRI before the study and/or come for an additional day 6 to repeat some of the questionnaires. There is no comparison group. All participants will receive the same treatment.
Intramuscular injection (IMI) is the process of administering a drug treatment into muscle tissue. The transmission of skills in this care practice is essentially based on the experience of peers. In France, there are no official guidelines for this technical procedure. Haloperidol decanoate is widely used in psychiatry. This long-acting antipsychotic treatment considerably reduces the risk of relapse and hospitalization. It is administered by IMI. This treatment is invasive, painful and risks complications for the patient. Nurses must ensure that the treatment is as painless as possible, and adapt their practice in line with current recommendations. Among the various IMI techniques available, the "Z-track" and the "Airlock" limit leakage into subcutaneous tissues when the needle is withdrawn, by locking the active product into the muscular tissues. According to an exploratory study (n=303), 73% of nurses observe active product leakage after injections, and 89% of nurses are not familiar with either the "Z-track" or "Airlock" techniques. Many foreign studies have been carried out to demonstrate the relevance of these techniques, particularly in terms of pain reduction during treatment, but the results have yet to be confirmed. The investigators hypothesize that the combined use of the "Z-track" and "Airlock" techniques during intramuscular injection of Haloperidol decanoate is more effective in reducing patient pain than usual practice.
The goal of this clinical intervention study is to investigate the effects of exergaming on cognition and other clinical symptoms in outpatient individuals with schizophrenia. The main questions it aims to answer are: Will an exergaming intervention contribute to improved cognition and reduced clinical symptoms, as well as enhanced physical health/self-efficacy/quality of life, in individuals with schizophrenia? Will the gaming component strengthen motivation for a physically more intensive component, so that attendance will be at least as high as in comparable exercise studies despite the current study being implemented in a resource-limited, regular clinical outpatient setting? Participants will be asked to engage in two 45 minutes exergaming sessions with a designated personal trainer for 12 weeks. Results pre- and post intervention will be compared, and comparisons will also be made with a former randomized controlled trial conducted at the same site, in which the currently combined activities were investigated separately (high-intensity interval training and low-intensity video gaming), both yielding positive but different effects.
A multimodal longitudinal study in early stage psychosis patients and individuals at high risk for psychosis. Healthy controls are included for baseline comparisons. The aim is to investigate disease mechanisms of psychotic disorders, specifically focusing on the synaptic pruning hypothesis.
Schizophrenia causes hallucinations, delusions, and disorganized thinking, resulting in decreased functioning and lifelong therapy.Delusion believability is the degree of belief in the truth of one's subjective experiences as representations of reality. It was unpleasant, typically accompanied by a suspicious, strange tension. Delusional belief is seen as a means of resolving tension and conflict in cognition and experience. Previous studies have shown that cognitive defusion strategies help people become more aware of their surroundings, accept their thoughts and feelings, and become more psychologically adjustable. defusion is crucial in reducing medication-resistant psychotic symptoms such delusions in schizophrenia patients. Therefore, this study aimed to investigate the effects of cognitive defusion techniques on psychological flexibility, mindful awareness, cognitive fusion, and believability of delusions among clients with schizophrenia. Research Hypothesizes - Clients who participated in cognitive defusion techniques had more psychological flexibility and mindful awareness than the control group. - Clients who participated in cognitive defusion techniques had less cognitive fusion and delusional believability than the control group.
It is currently unknown what factors predict response to Cognitive Behavioural Therapy for Psychosis (CBTp) or Cognitive Remediation Therapy (CR) among individuals with schizophrenia-spectrum disorders, thus the current trial will examine predictors of response to determine who requires the combined intervention and who might respond sufficiently to either monotherapy.
Repetitive transcranial magnetic stimulation (rTMS) can alleviate persistent auditory verbal hallucinations (AVH) in schizophrenic patients, but the classical procedure with low-frequency stimulation for several weeks upon the left temporoparietal junction have shown modest therapeutic effects, and there is currently no robust predictive factor to the response of the treatment. In a previous multicentric, randomized, and double-blind controlled study, it has been demonstrated that a high-frequency rTMS over an anatomical target can rapidly affect AVHs. Moreover, an intensification of the classical procedure delivering 20-Hz rTMS over a 2-day period was used in addition to a personalized anatomical stimulation target and neuronavigation guidance. Besides the significant efficacy of the procedure, the efficacy was maximal at two weeks after the end of the treatment. In this project, the hypothesis is that the two-day cure could benefit from maintenance rTMS sessions every week for one month and then every two weeks for 3 months to provide an optimal strategy for a long-lasting AVH reduction. This has for now never been tested. Predictive factors to the response of the treatment are also investigated.
Cognitive impairment is well established in people with psychosis and is associated with cannabis use. The current study will investigate the neurobiological basis of cognitive change associated with 28-days of cannabis abstinence in people with psychosis and non-psychiatric controls with cannabis use. Participants will be randomized to a cannabis abstinent group or a non-abstinent control group and will undergo magnetic resonance imaging at baseline and following 28-days of abstinence. This study will help characterize the neuropathophysiological processes underlying cognitive dysfunction associated with cannabis use and its recovery which may guide the development of novel interventions for problematic cannabis use.
