Active clinical trials for "Psychotic Disorders"

Pregnant women who are taking lamotrigine will be evaluated monthly during pregnancy including a clinical evaluation and a blood draw for lamotrigine levels at each visit. Based on the Therapeutic Drug Monitoring protocol, participant's lamotrigine dosing will be adjusted as needed based on participant's blood levels compared to the reference concentration that was obtained prior to pregnancy or early in pregnancy while clinically stable. After delivery participant and participant's infants will be assessed for mood and functioning at 1, 2, 4, and 6 weeks postpartum.

Serious mental illnesses (SMI) like schizophrenia and bipolar disorder are two of the most disabling and costly chronic illnesses worldwide. A high proportion of adults with schizophrenia and bipolar disorder have sleep disorders, like obstructive sleep apnea (OSA), but tend to be underdiagnosed and undertreated compared to the general population. This study aims to examine feasibility, acceptance, and impact of OSA treatment and how it affects cognitive function in people with SMI.

The overall aim of the proposed study is to determine the feasibility, acceptability, fidelity, and preliminary effectiveness of the adapted nurse-led, community-based rehabilitation treatment model for community-dwelling individuals living with psychosis in Blantyre, Malawi using a pilot randomized controlled trial.

This longitudinal observational study tests the associations between physical activity, health-related quality of life, and psychopathology symptoms among people diagnosed with schizophrenia or diagnosed with affective disorders. It was assumed that higher levels of physical activity at baseline will be related to better quality of life (across physical, social, and psychological domains), and lower psychopathology symptoms (positive and negative symptoms of psychosis, general psychopathology, and depression severity) at 6-week follow-up measurement. Adult participants with a diagnosis of a psychotic disorder or a diagnosis of an affective disorder will be enrolled.

The aim of this pilot study is to examine whether metacognitive training can improve symptoms, wellbeing and functioning in individuals with attenuated psychotic symptoms. Metacognitive group training is an intervention designed to raise awareness on and change cognitive biases that may foster the development of psychotic symptoms such as delusions. It has been shown to be helpful in people with manifest psychosis. The main goal is to assess whether this training is prone to reducing symptoms in individuals at risk for psychosis. Participants will be randomized either to treatment as usual or to treatment as usual plus metacognitive training. Follow-ups will be performed over the period of one year.

The aim of this observational study is to get a better understanding of the association between problem gambling psychotic disorders among young adults with firs-episode psychosis. The main questions to be answered are: What are the incidence and risk factors for problem gambling in this population? How effective are the current treatments for problem gambling in adults with first-episode psychosis? To do so, comparisons will be made among the study cohort for various factors: Use of dopamine partial agonists; Psychiatric comorbidities; Socioeconomic status; Sex; Gender; Gambling history. The nature of the treatments for problem gambling offered and received by the subjects, as well as their effectiveness, will also be documented.

SchizOMICS is a Phase IV, multicenter, dose-flexible, open-label, randomized controlled clinical trial to evaluate the efficacy and safety of aripiprazole versus paliperidone using multi-omics data in patients with a first psychotic episode. The trial will include a total of 244 patients, with two arms of treatment with paliperidone and aripiprazole (1:1). The main objectives of the study are: To compare the efficacy and safety of aripiprazole and paliperidone in the treatment of first episode psychosis (FEP) subjects in real-world clinical settings at 3 months. To elucidate whether non-responders after 3 months of adequate treatment may display different molecular signatures at baseline based on multi omics data and systems biology analysis. To uncover whether the appearance of side effects after 1 year of adequate treatment may be related to different molecular signatures based on multi-omics data and lifestyle phenotype using systems biology analysis.

The main objective of the study is to measure the plasma and intracellular levels of several neuroinflammation markers (including cytokines and chemokines) and the endocannabinoid system in subjects presenting psychotic symptoms, initially recruited in a Mental Health Hospitalization Unit, and in different stages of their disease. To this end, we will evaluate and clinically characterize a cohort of patients who present active psychotic symptoms at the time of recruitment, and comparing it with a control group with similar sociodemographic characteristics. We will also compare our sample with a smaller sample previously recruited from patients with substance use and psychotic symptoms. Within our cohort of patients with psychotic symptomatology we will distinguish in turn affective psychoses from non-affective psychoses, on the one hand; and induced and non-induced psychosis by drug consumption, on the other. We will also classify patients based on whether they are experiencing the first episode of their illness or a relapse. This is an observational, longitudinal and prospective study. 3 blood draws will be performed from the subjects included in the study: the first, in the first 48 hours of hospital admission; the second, in the 48 hours prior to discharge; and the third, 6 months after discharge. The rater team will be composed of senior psychiatrists and training psychiatrists. The sample will be composed of subjects with psychotic symptoms who come from the Mental Health Clinical Management Unit of the Regional University Hospital of Malaga. Each patient enrolled in this study will undergo a clinical evaluation (psychiatric diagnostic interview and psychometric scales). From the plasma and white blood cells of the blood sample, the biochemical levels of the inflammatory mediators will be determined. Demographic, clinical, and biochemical data will be assessed and analysed using statistical programmes.

Psychosis is a severe mental disorder that involves abnormal experiences and altered behaviour. Although the onset of psychosis occurs in young people, most cases will only be identified later in the course of illness. The delayed detection is the main cause of significant negative long-term outcomes. The current proposal will develop an innovative E-mental health detection tool to effectively improve the identification of young people with emerging psychosis. This tool will be implemented on digital platforms including websites, tablets and mobile phones. Young people will be asked to complete an online questionnaire and two short online-exercises and will then be invited for face-to-face assessments to further confirm whether they are experiencing an emerging psychosis. This digital approach leverages previous expertise by the research team and it is expected to provide novel avenues to enable the identification of young people with emerging psychosis.

This is an observational neuroimaging treatment study. This study involves examining the neural circuitry of controlled treatment of patients presenting with a first-episode of psychosis with risperidone or aripiprazole. Patients who present for treatment of a first psychotic episode with a schizophrenia spectrum diagnosis and who are eligible to undergo treatment with either risperidone or aripiprazole will be offered participation in the study. Clinical ratings, neuropsychological testing, neuroimaging and EEG will be conducted at baseline. Additionally, subjects will undergo the same assessments at week 12 to determine treatment-related biomarkers. Clinical ratings, including neurocognitive testing, will be conducted by blinded raters at study visits during treatment. Healthy controls (N=50) will also be recruited and scanned twice (12-week interval) to control for effects of time and practice.
