Filter by:The purpose of this study is to assess if access to an electronic nicotine delivery device, or e-cigarette, in addition to nicotine patch (21 mg) can help reduce cigarette smoking among individuals diagnosed with schizophrenia compared to nicotine patch alone.
To test the hypothesis that functionally navigated repetitive TMS stimulations to the prefrontal cortex (PFC) modulate aberrant cortical electrical activities at PFC circuitry. The TMS location of the PFC site will be individually localized by the symptom-related functional connectivity between PFC and symptom related areas (such as the auditory and language processing cortex). The investigators predict that such modulation will correct abnormal activities in patients with schizophrenia, reduce symptoms, especially auditory hallucination, and improve working memory/sustained attention performance.
Schizophrenia has very significant economic consequences. Costs fall on many different parts of society, especially on individuals with schizophrenia and their families. The first five years after onset appears to be a critical period in which the symptoms are more responsive to treatment. In addition, if left untreated for a long time, psychosis can impact many areas of a person's life. The evidence base regarding the effectiveness of specialist early intervention services for psychosis has grown steadily and evidence from randomized controlled trials in Denmark, the United Kingdom and Spain has demonstrated the superiority of specialized early intervention programs over standard care on a broad range of outcomes including symptomatic and vocational, social functioning, and reduced inpatient care and treatment dropout, as measured over follow-up intervals of 2-3 years. Information about the cost-effectiveness of early intervention programs for first-episode psychosis is limited. The provision of such services requires investment by health departments and services, and the question of whether such services represent value for money has to date received little research attention. Only a few international studies, and none conducted in Spain, have investigated the cost effectiveness of early intervention in psychotic disorders at medium (3 years) and long-term (up to 10 years). In this study, the investigators aimed to analyse the cost-effectiveness of an intensive early-intervention programme, using data from First Episode Psychosis Clinical Program (PAFIP), the largest trial treating first episode non-affective psychosis in Spain to date.
The investigators study aims are: 1. To investigate folate, vitamin B12, and homocysteine levels in patients with schizophrenia. 2. To evaluate the relationships among folate, vitamin B12, and homocysteine levels, genetic variants of one-carbon cycle pathway, psychopathology, including positive symptoms, negative symptoms, and cognition, and metabolic abnormalities in patients with schizophrenia. 3. For patients with low folate levels, the investigators would like to conduct a 24-week double-blinded, placebo-controlled of folic acid (5 mg/d) and vitamin B12 (500 ug/d) supplementation study to know whether combination of folic acid and vitamin B12 can improve patients' psychopathology or metabolic profiles, and the effects of genetic variants in one-carbon cycle pathway on treatment response.
This study evaluates the addition of psychoeducation to treatment as usual in the treatment of adults with schizophrenia for relapse prevention. Half of participants will receive a brief (5 sessions) psychoeducation intervention and treatment as usual in combination, while the other half will receive treatment as usual only.
Current medications have only a limited effect on two core symptoms of schizophrenia, negative symptoms and cognitive deficits. Minocycline is a second-generation tetracycline which has a beneficial effect in various neurological disorders. In the past years, various findings from clinical studies showed its potential role for the treatment of these symptoms of schizophrenia. The current study aims to examine the efficacy of minocycline as add-on treatment for alleviating positive, negative and cognitive symptoms in schizophrenia patients.The current study is a single center, double-blind, randomized study that assess the adjuvant therapeutic effect of minocycline vs. placebo added to antipsychotic medications, in adult patients suffering from schizophrenia. Patients will be recruited and randomly allocated to a minocycline or placebo treatment (200 mg/day) for 6 weeks of treatment. In addition, all patients will receive probiotics (450mg/day) in order to prevent any gastrointestinal influences of antibiotics administration. Positive and negative symptoms , as well as cognitive functions will be assessed before and after treatment.
This study evaluates the role of the Nitric Oxide system in cognition in patients with schizophrenia. Participants will be randomised to 2 equal groups and receive either the Nitric Oxide donor molecule glyceryl trinitrate, or a placebo. Performance on several cognitive tasks will be assessed.
The primary objective is to evaluate if repetitive transcranial magnetic stimulation (rTMS) with theta burst frequency over dorsomedial prefrontal cortex (DMPFC) is an effective treatment for negative symptoms (anhedonia and avolition) in schizophrenia or depression. Other objectives are to increase the understanding of the underlying neurobiology of negative symptoms and the mechanisms for the treatment effect of rTMS.
The purpose of this study is to investigate the effect of Lu AF35700 on electrical activity in the heart as measured on an electrocardiogram (ECG) in patients with schizophrenia or schizoaffective disorder after 6 weeks of treatment
Interventional, multicenter, and longitudinal study, of a cohort of patients with schizophrenia, evaluated on social cognition, neurocognition, symptoms, functioning with 12 months interval.
