Filter by:The investigators propose to recruit individuals with schizophrenia who are symptomatically stable and already taking medications to participate in this study. The investigators will recruit 90 individuals with schizophrenia and randomize them to low and high doses of DAR-0100A, as well as to placebo. The investigators will have them stay in the hospital for several weeks and receive up to 10 doses of DAR-0100A. The investigators will also test their cognition before and after receiving DAR-0100A to see if DAR-0100A is helpful and perform MRI scans before and after taking the medication to see which areas of the brain are activated when DAR-0100A is administered. These tests will be very important because they will help the investigators determine whether the D1 receptor is a good treatment target for schizophrenia and whether more research and resources should be devoted to finding medications that target this system. Patients with schizophrenia will be free of other medical, psychiatric and neurological disorders including alcohol and substance dependence, and will be able to understand the nature of the study and to provide informed consent.
The aim of this study is to develop a scale to measure the severity of depression with psychotic symptoms (psychotic depression). Furthermore, we hope to detect potential biomarkers (substances in the blood) which can aid in the detection of psychotic depression. Main hypothesis: A clinically valid rating scale measuring the severity of psychotic depression can be developed.
Auditory verbal hallucinations (AVH) are a characterising symptom of schizophrenia. In the majority of patients, these AVH respond well to antipsychotic medication. Yet, a significant minority continues to experience frequent AVH despite optimal pharmacotherapy. The number of alternative treatment options for this medication resistant group is currently low and most of them focus on coping with the hallucinations. Transcranial magnetic stimulation (TMS), in contrast, is a non-invasive technique of influencing cortical excitability. This technique has the potential to actually decrease the frequency and severity of medication resistant hallucinations. Several previous studies have assessed efficacy of low frequency rTMS, with contradicting results. A previous large study by the investigators group could not demonstrate efficacy of low frequency rTMS. A new stimulation protocol using theta burst rTMS (TBS) could provide a more effective therapeutic option. Objective: The present study aims to examine the efficacy of TBS on the severity of AVH. Study design: The objectives are tested in a randomized double blind placebo-controlled trail. Study population: 60 patients with the diagnosis of schizophrenia, schizoaffective disorder, schizophreniform disorder or psychosis not otherwise specified with frequent auditory verbal hallucinations will be included. Intervention: The participant will receive either 10 TBS treatments or 10 placebo treatments consisting of 900 pulses each with a 30 minute interval on the left temporoparietal area, distributed over 5 treatment days. Stimulation will be at 80% of the motor threshold. Main study parameters/endpoints: the main study parameter is the change in the severity of the AVH. The secondary study parameter is the number and severity of adverse events.
The purpose of the present study is to examine whether cognitive behavior therapy will reduce depressive symptoms and increase self-esteem for patients with a first episode psychosis.
In order to meet an existing lack of empirical studies in the field of cognitive behavioral therapy supervision, the present randomized controlled trial is aimed at comparing two different types of supervision. This study compares computer-assisted live supervision and delayed video-based supervision regarding efficacy and acceptance among therapists, patients and supervisors. The efficacy of supervision is defined on different levels such as change of psychotherapeutic competence, nondisclosure, self-efficacy, self-awareness of the supervisee as well as therapeutic alliance, supervisory alliance and therapy outcome.
The investigators will develop, deliver and evaluate a solar powered tablet-based individual and group focused HIV/STI prevention intervention with internally displaced women in Leogane, Haiti. Internally displaced women will be trained as community health workers to deliver the HIV/STI prevention intervention to other internally displaced women.
The objective of this study is to evaluate the efficacy and safety of RP5063 relative to placebo for the treatment of schizophrenia or schizoaffective disorder.
Persons with serious mental illness (SMI) are at increased risk of cardiovascular disease (CVD). The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and improve mental health and physical health-related quality of life, as well as to get feedback from patients and providers on what is needed to help better coordinate the physical and mental health care of these patients.
The aim of this project is to investigate the effect of Raloxifene 120mg in men with schizophrenia. This trial will adopt a 12 week randomised controlled model. Hypotheses 1: That the men receiving adjunctive selective estrogen receptor modulators (SERM) will have a significantly greater reduction in psychosis symptoms over the course of the study than men receiving adjunctive placebo. Hypotheses 2: That the men receiving adjunctive SERM will have a significantly greater improvement in cognitive function than men receiving adjunctive placebo
The purpose of this study is to determine the effectiveness, with respect to symptoms and systemic inflammatory level, of mindfulness-based group treatment compared with normal treatment in patients diagnosed with minor to moderate mental disorders. The hypothesis is that mindfulness group-treatment 1) will be at least as effective as normal treatment in reducing psychiatric symptoms; 2) will increase quality of life compared with normal treatment; 3) will be costeffective compared with normal treatment; and 4) will reduce inflammation-related markers. The study will be conducted at primary care centers in Skåne, Sweden. We will assess the effect of mindfulness-based group treatment on psychiatric symptoms, quality of life, and health (as rated by the patients themselves) as well as inflammatory markers.
