RCT Comparing Avatar Intervention to Supportive Intervention to Reduce Cannabis Use in Patients...
Psychotic DisordersCannabis Use Disorder1 moreThe goal of this clinical trial is to conduct a single-blind randomized controlled trial to verify whether the Avatar Intervention has greater efficacy over supportive intervention to reduce cannabis use in patients with psychotic disorders.
Hjernegym - Effects of Exergaming in Psychosis: a Clinical Intervention Study
Schizophrenia; PsychosisCognitive ImpairmentThe 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.
Remote State Representation in Early Psychosis
PsychosisSchizophrenia9 moreThe purpose of this study is to examine state representation in individuals aged 15-40 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.
Effectiveness of an Evidence-based Stepped Care System for Alcohol and Other Drug Use Problems Among...
Alcohol and Substance-Related Mental DisordersThis is a randomized controlled trial (RCT) evaluating the effectiveness of a screening, brief intervention, and referral to treatment (SBIRT) stepped-care system in reducing unhealthy AOD use among Congolese refugees and the host community in Mantapala, an integrated settlement in northern Zambia.
Comparing Antipsychotic Medications in LBD Over Time
Parkinson's Disease PsychosisDementia With Lewy BodiesThe primary objective of this study is to determine whether treatment with pimavanserin or quetiapine is associated with a greater improvement in psychosis when used in a routine clinical setting to treat hallucinations and/or delusions due to Parkinson's disease (PD) or dementia with Lewy bodies (DLB) - collectively referred to as Lewy body disease (LBD).
mHealth for Psychosis Help-seeking
PsychosisThe proposed study research project aims to develop and test a mobile health intervention designed to improve the wellness of young people at risk for psychosis and facilitate users' engagement with treatment and thus reduce duration of untreated psychosis. This clinical trial will involve a remote pilot randomized controlled trial that will examine (1) the feasibility of the proposed research approach, (2) the acceptability and usability of the NORTH intervention as well as (3) the specific additive value of help-seeking support in the context of self-guided mHealth for early psychosis. The full intervention, which includes psychoeducational lessons, Cognitive-Behavior Therapy-based practices, a symptom tracking feature, and help-seeking resources will be compared to a "Lite" version that will include the lessons, practices, and tracking but exclude the help-seeking resources.
Targeting Emotion Dysregulation to Reduce Suicide in People With Psychosis
PsychosisSuicidePeople with psychotic disorders are excluded from most suicide-focused clinical trials despite incredibly high rates of completed suicide, and interventions that have been tested for this population have shown limited impact on suicide. Emotion dysregulation is a significant suicidogenic factor that is understudied in people with psychotic disorders. The investigators propose to implement and evaluate an intervention targeting emotion dysregulation in people with psychotic disorders while employing rigorous statistical modeling and measurement techniques including Ecological Momentary Assessment, which will support future advanced research on suicide and suicide prevention for this high-risk group.
R33: Levetiracetam in Early Psychosis
Early PsychosisThis is a 12-week study of levetiracetam added to a second generation antipsychotic in early psychosis patients who have been ill for less than 5 years and continue to experience psychotic symptoms despite at least 8 weeks of antipsychotic treatment. Levetiracetam (Keppra) is a medication approved for the treatment of epilepsy; it reduces excessive activity in the brain. This study will test the hypotheses that adding levetiracetam will improve psychotic symptoms that are unresponsive to antipsychotic treatment and will protect the brain from atrophy (volume loss). .
Investigation of Neurophysiological Markers, Possibly Specific of Two Subforms of Psychotic Disorders...
SchizophreniaThe current diagnostic criteria for schizophrenia and other psychotic disorders are relatively broad and lack precision. Therefore, distinct diseases may be grouped together under the same diagnostic category, although these diseases may differ according to their clinical expression, prognosis and perhaps their physiopathological causes. We think that identifying subforms of psychotic disorders that are more homogeneous will better enable to understand their respective physiopathological causes and find personalized treatments. This study will compare two subforms of psychotic disorders that have been clinically distinguished in the 1970s. These phenotypes have however not been validated yet using scientific investigations. Using clinical assessments, cognitive evaluations and neurophysiological measures (fMRI) investigating the domains of affect and psychomotoricity , we expect that these two subforms will differ on their clinical, cognitive and neurophysiological characteristics, namely: hebephrenia will be associated with deficits on the affect markers , and respect psychomotoricity (catatonia scales, tests assessing movement planification) whereas the opposite pattern will be observed for periodic catatonia.
