Filter by: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.
This study aims to provide an evidence-based behavioral intervention to reduce violent behavior for individuals experiencing early psychosis.
Cognitive impairment (such as challenges in thinking and memory) is a core aspect of schizophrenia (SCZ), contributing to disability and poor functional outcomes. Additionally, almost half of the patients with SCZ are obese, the prevalence of type 2 diabetes is 3-6 times higher, and life expectancy is lower by 15-20 years compared to the general population. This is relevant as metabolic syndrome and diabetes are both associated with worse cognition among SCZ patients. Recent work studying the relationships between metabolic health and cognition has encouraged a new way of thinking about SCZ as both a metabolic and cognitive disorder. Brain insulin is involved in several processes relevant to SCZ, and abnormal brain insulin action may help explain both cognitive and metabolic abnormalities in patients with SCZ, but this has not been examined previously. Glucose uptake in several brain regions relevant to SCZ has been shown to be partially dependent on insulin. Therefore, in this study, the researchers will measure glucose uptake in the brain using an 18F-fluorodeoxyglucose ([18F]-FDG) positron emission tomography (PET) scan after an intranasal insulin stimulus, and will compare this measure between patients with SCZ and healthy controls.
The purpose of this study is to understand the relationship between psychotic symptoms and social functioning in individuals with schizophrenia spectrum disorders. Our goal is to determine whether stimulating the brain using transcranial Direct Current Stimulation (tDCS) can improve symptoms and daily functioning.
This study will take place at one outpatient clinic serving adults with serious mental illness and will recruit ten individuals (N=10) with a DSM-5 diagnosis of schizophrenia or schizoaffective disorder to participate in an Open Trial of Motivation Skills Training (MST). MST is a weekly group-based skills training intervention that aims to improve knowledge about one's level and sources of motivation, the ability to monitor and regulate (understand and manage) motivation, so that one can better initiate and sustain goal-directed behavior. Participants who consent for research will complete assessments of motivation, goal attainment, quality of life, executive functioning, community functioning, and psychiatric symptoms severity. The intervention phase will be approximately 12 weeks in duration and will entail weekly MST group sessions. At treatment endpoint, participants will be asked to repeat the assessment battery from baseline as well as a satisfaction survey. Change in motivation, goal attainment and quality of life will indicate whether MST is engaging the hypothesized target (motivation) and whether there is impact on functioning.
An Extension study to a clinical study that will continue to evaluate the effectiveness and safety of SEP-363856 in people with schizophrenia that switch to SEP-363856 from their from their current antipsychotic medication. This study will accept both male and female participants that have completed study SEP361-308. This study will be held in approximately 24 study sites in North America. Participation in the study will be approximately up to 25 weeks.
The specific aim of this protocol is to compare Clozapine treatment vs Non-Clozapine antipsychotic treatment in a population of treatment-refractory individuals with schizophrenia. Specifically, it is to test if Clozapine leads to a decrease in levels of inflammatory markers, namely interleukin-6 but with an exploratory view of other markers. Clozapine has superior efficacy and is the only medication approved for treatment-refractory schizophrenia in addition to decreasing the risk of suicidal behavior as well. It is unclear why Clozapine has increased efficacy from a mechanistic viewpoint. We will look at the role of inflammatory markers and assess them 1x along with rating scales for psychosis and suicidality, the other entities which Clozapine has been shown to improve.
People with schizophrenia have low functionality and psychological resilience. Psychological resilience of individuals can be improved. The funcionality of individual with improved psychological resilience can also be improved. Therefore, both resilience and functionality can be increased by appliying resilience programs to patients with schizophrenia.
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.
