Active clinical trials for "Schizophrenia"

A short term post-market monitoring of serum prolactin level change among patients with schizophrenia shifting from other antispychotics to different dosages of aripiprazole.

The purpose of this study is to evaluate the safety of risperidone treatment in patients who are overweight and/or obese.

Switching from Risperidone to Aripiprazole in early stage of pharmacotherapy will demonstrate the same efficacy as compared to risperidone continuation treatment in the treatment of schizophrenia.

The study is a multicenter, double-blind, randomized, parallel-group study with first episode schizophrenic patients. During a treatment phase of 8 weeks the patients are treated with Risperidone or Haloperidol. Aim of the project is to compare the effects of the atypical neuroleptic Risperidone with those of the conventional neuroleptic Haloperidol and to evaluate whether the assumed advantages of atypical neuroleptics compared to conventional neuroleptics are also present when both medications are administered in rather low daily dosages (min. 2 mg/d; max. 8 mg/d).

A study of children and adolescents (current N=100) with very early onset by age 12 (COS) of DSM-III-R defined schizophrenia with (97-M-0126) is examining the clinical, neurobiological, early neurodevelopmental, genetic, and clinical drug response characteristics of these cases. Earlier studies have documented the continuity between COS and adult onset cases (See Jacobsen and Rapoport, 1998 for review). The focus has now shifted to increasing the sample size and evaluation of familial risk factors including: psychiatric diagnoses of family members; smooth pursuit eye movements; neuropsychological tests deficits, and obtaining blood for cell lines for genetic studies (family members only, this is also covered under 96-M-0060, Dr. Ellen Sidransky). A study of obstetrical records of COS probands indicated no increase in adverse pre or perinatal events for these cases compared with obstetrical records of their siblings (Nicolson et al submitted). In contrast, several findings point to increased risk for these probands. To date, a total of 5 (10.4%) COS subjects were found to have previously unknown cytogenetic abnormalities (Microdeletion of 22q11 (3 cases), (Usiskin et al, submitted), Mosaic 45X0 (one case) (Kumra et al, 1998) and balanced 1:7 translocation (Gordon et al 1994). The study of first degree relatives of these very rare cases addresses the hypothesis that risk factors, most probably genetic, are increased in immediate family members relative both to community controls and to the relatives of patients with chronic, treatment resistant, adult-onset schizophrenia (AOS). A second hypothesis is that COS familial risk factors show significant relationship to the developmental delays/abnormalities being observed in the COS probands. As a total of 50 additional COS subjects will be studied over the next 5 years, the pediatric control sample for the probands will also be increased, determined by the need to have concurrent measures for patients and controls to maintain measurement validity. Thus a total of 600 additional subjects are to be studied including 50 controls for COS probands, 150 COS relatives, 150 controls for COS relatives, and 250 relatives of adult onset schizophrenics (AOS).

Self-stigma refers to the transformation process wherein a person's previously held social identity is progressively replaced by a devalued and stigmatized view of oneself termed "illness identity". Self-Stigma is a severe problem in Serious Mental Illness (SMI). Self-stigma prevalence is high (41.7% of the 1229 participants with SZ and 21.7% of the 1182 participants with mood disorders had moderate to high levels of IS in the GAMIAN-Europe study). Self-stigma was negatively associated with self-esteem, social function, wellbeing, quality of life or personal recovery and positively associated with psychiatric symptoms and depression. Several psychosocial interventions (mostly combinations of psychoeducation and cognitive behaviour therapy) have been designed to reduce self-stigma and its impact on clinical and functional outcomes, with preliminary effects on self-stigma, insight and self-efficacy. Narrative Enhancement and Cognitive Therapy (NECT) is a manualized structured 20-session group-based intervention . Conducted by two trained facilitators the sessions combine psychoeducation, cognitive restructuring and story-telling exercises to reduce self-stigma. Developed in USA, NECT was adapted in Israel and Sweden. NECT showed effectiveness in reducing self-stigma and in improving self-esteem and quality of life. Despite being effective on changing coping strategies, NECT effectiveness on social function is still unclear. The present study aims to validate NECT French adaptation and to evaluate its effectiveness on social function, self-stigma, psychiatric symptoms, self-esteem, wellbeing, quality of life and personal recovery in SMI participants (schizophrenia, bipolar disorder, borderline personality disorder)

Negative symptoms (e.g. diminished pleasure and motivation) are common in people with a diagnosis of schizophrenia. Little is known about the psychological mechanisms involved in negative symptom development and maintenance and there is limited evidence for current treatment options. Some research suggests that difficulties with metacognition; the capacity to develop and use complex ideas about oneself and others, may predict experiences of negative symptoms. This study will investigate whether Metacognitive Reflection and Insight Therapy (MERIT) improves metacognition in people experiencing negative symptoms, and if metacognitive changes lead to observable differences in behavioural manifestations of negative symptoms (e.g. low activity levels). Data will be collected via standardised assessments of metacognition and negative symptoms. Activity levels will be measured with actigraphy, which has been shown to capture differential activity patterns for individuals who experience negative symptoms compared to control groups. An assessment will also be made of whether improvements in specific aspects of metacognition (e.g. self-reflectivity) relate to changes in individual negative symptoms, such as motivation levels, and other markers of personal change, including personal and social performance, insight, and beliefs about recovery. Additionally, factors that may have impacted on the study results, such as therapist adherence to the treatment, will be reported. Eligible patients with capacity to consent will be recruited from the inpatient rehabilitation psychology services in National Health Service (NHS) Greater Glasgow and Clyde. They will be aged 18 or over, have a schizophrenia spectrum disorder diagnosis, and experience current negative symptoms. The target sample size is up to 8 patients. Participants will be measured at baseline and will receive up to 26 sessions of the MERIT treatment approach. Any therapeutic change will be observed via changes from assessments at baseline to the assessments in the initial, middle and last therapy sessions, and also metacognitive assessments at two other randomly selected time-points during therapy.

This research compares the relative efficacy of two empirically-supported, standardized programs of cognitive remediation for treatment of cognitive deficits and community function in schizophrenia to help inform best practices. The proposed study advances public health by developing and evaluating new behavioral techniques for improving psychosocial outcome in individuals diagnosed with schizophrenia.

This study aimed to investigate the effects of lifestyle redesign program plus treatment as usual versus treatment as usual on cognition, psychiatric symptoms, quality of life, and occupational engagement for schizophrenia.

The main objective is to determine the effectiveness of a program which consists of multidisciplinary, intensive and individualized interventions, carried out by a group of health professionals (psychiatrist, psychologist, mental health nurse, primary care doctors, pharmacist), during six-month, to improve the global cardiovascular risk (CVR) in patients with schizophrenia. Secondarily, will be analyzed the effectiveness of this program on improving the control in four selected cardiovascular risk factors: hypertension, hypercholesterolemia, hyperglycaemia and smoking, after 6 months Methods: randomized study with parallel assignment in two groups: control and intervention group, six-month follow-up. The eligible patients will be 130 adult (≥18 years) outpatients with a current diagnosis of schizophrenia who follow-up by health mental network in Catalonia, who presents at least bad control in one of the four selected cardiovascular risk factors. The intervention group will receive a multidisciplinary and individualized approach (psychoeducational, recommendations of life style and diet, medication adherence and changes in pharmacological strategy, depending on the individual needs assessing after cardiovascular risk screening. The control group will follow the standard management according to the primary care professionals' team. Main measurements: the global CVR at baseline and at six-month follow-up through Framingham tables calibrated for the Catalan population (Registre Gironí del Cor, REGICOR). Secondary measures: they will be determined, at baseline and at six-month follow-up, four cardiovascular risk factors as well: hypertension, hypercholesterolemia, hyperglycaemia and smoking, according with the latest recommendations of the Program of preventive activities and health promotion (PAPPS) of the Spanish Society of Family and Community Medicine. Other measures: anthropometric parameters. Functional Assessment Screening Tool (FAST) and quality of life (EQ-5D).
