Active clinical trials for "Schizophrenia"

This study will evaluate the safety of multiple doses of NSA-789 in subjects with schizophrenia or schizoaffective disorder. This study will also assess how NSA-789 is absorbed and eliminated, and its effect, if any, on the brain.

The purpose of this study is to evaluate the effect of single doses of NSA-789 on the P50 component of the auditory evoked potentials and to assess the safety, tolerability and the concentration of NSA-789 in the blood, in nonsmoking patients with schizophrenia.

The objectives of this 15-day study are: To compare steady-state trough plasma concentrations of clozapine and its metabolite norclozapine when given once daily and twice daily (at the same total daily dose) To determine if frequency of clozapine administration has an effect on: Symptoms of schizophrenia Adverse effects of clozapine Fasting blood glucose, lipids, creatinine, and urea Weight and waist circumference

This study aims to gather additional information to support the theory that bipolar disorder is due to cellular (mitochondrial) dysfunction. To test this theory adults with bipolar disorder who are not currently symptomatic will receive a one-time brain scan (magnetic resonance spectroscopy [MRS] scan) with light stimulation. To test whether any MRS findings are specific to bipolar disorder, healthy controls and adults with schizophrenia will also be included in this study.

Brief Summary: Definition: A short description of the clinical study, including a brief statement of the clinical study's hypothesis, written in language intended for the lay public. Limit: 5000 characters. The purpose of this study is to investigate the relationship between speech features and severity of positive and negative clinical symptoms in Arabic speaking patients with schizophrenia. Individuals will be invited to participate in this study because (1) they have a confirmed clinical diagnosis of schizophrenia; (2) they plan to receive routine clinical care for schizophrenia at one of the four participating sites; (3) they speak Arabic as a first language. Participants must be between the ages of 18-65 years. Participation will involve seven visits consisting of one baseline visit and six monthly follow-up visits. All participants will continue to receive routine clinical care. Participation in this research will involve providing speech samples using standardized tasks collected using an electronic device. Additionally, study team members will assess positive and negative symptoms of schizophrenia using validated questionnaires.

Randomized controlled trial. Sixty-five participants (83% with schizophrenia or bipolar disorder) were recruited from community mental health teams. Fifty-seven met criteria and agreed to participate in the study. The conditions of cognitive rehabilitation were assigned randomly with support employment CR + IPS (n = 28) and IPS alone (n = 29). Cogpack program was used. Two groups were followed at 8 and 12 months after the baseline.

The aim is to contribute to the knowledge of the relationship between Motor Neurological Soft Signs (MNSS) and schizophrenia, as well as to point out the implications and recommendations for clinical and rehabilitative practices, in order to contribute to the identification of these signs as potential facilitators of prevention and a better follow-up in the psychosocial rehabilitation processes of the person with schizophrenia.

The study of immune pathways involved in the etiopathogeny of schizophrenia would be an important advance to understand the mechanisms involved in the development of this disease and it would be a turning point in drug therapy. Until now, the mechanism of action of antipsychotics focused on the blockade or modulation of brain dopaminergic pathways. If immunological pathways responsible for neuroinflammation and neurodegeneration which involve alterations in different areas and brain pathways (including dopaminergic pathways) are discovered, investigators could develop new treatments that act on these new targets, allowing to delay the onset of the first psychotic episode and improve the evolution and impact of this disease.

Psychomotor slowing may occur in major psychiatric disorders, such as major depressive disorders or schizophrenia spectrum disorders. It refers to slowing of fine motor skills, motor planning and gross motor behavior. In major depression and schizophrenia, psychomotor slowing is associated with alterations of premotor cortex, dorsolateral prefrontal cortex and basal ganglia. This randomized, sham-controlled, prospective trial will test, whether 15 sessions of repetitive transcranial magnetic stimulation (rTMS) may ameliorate psychomotor slowing in schizophrenia or major depression.

People suffering from psychotic illnesses (e.g. schizophrenia) have poorer physical health than the general population. The reasons include a lack of service user motivation to attend physical health checks and the tendency of health professionals to focus mainly on the mental disorder thus delaying the detection of physical health conditions. Identifying people who have physical health needs is increasingly recognised as a priority. The investigators have developed a Physical Health Plan (PHP) which is completed by service users and identifies areas of physical health need. An action plan is then completed by the service user and care co-ordinator to address these issues. The PHP is designed to be very simple to use and there will be 3 versions, 1. paper version, 2. 1 version implemented via the 'IMPARTS' computerised 'tablet' based system that has been separately evaluated (REC Ref 12/SC/0422) and 3. 1 version on an iPad via the MHL2 system via Mindwaves. The investigators wish to pilot the use of this PHP in two community teams in the South London and Maudsley (SLaM) Trust. The pilot will be done in three stages. Stage One: The investigators will undertake an initial qualitative study to refine the process of using the PHP using focus group consultations with staff and service users. Stage Two: The investigators will then undertake a six month study to evaluate the uptake and use of the PHP. This will involve collecting data on how many people complete the PHP and what actions are taken following the completion of the PHP. Stage Three: At the end of this six month period the investigators will undertake qualitative interviews with a selection of service users and staff to understand their experience of using the PHP. The investigators hope to be able to use the results of this pilot study to introduce the use of the PHP into routine care.
