Active clinical trials for "Schizophrenia"

This study is designed to find quantitative Electroencephalogram(qEEG) biomarkers to predict Electroconvulsive Therapy(ECT) Response in Schizophrenia

The purpose of this study is to estimate the level of symptomatic and psychosocial remission of patients with schizophrenia and schizoaffective disorder in standard clinical practice as a function of the degree of adherence to antipsychotic treatment. The secondary objectives are to study the level of community integration of the patients included in the study, and its influencing factors, to analyze the role of various sociodemographic factors, factors related to the course of disease and the psychopathological status of the patient in community integration and remission, to analyze the potential predictors of a favorable course (symptomatic and psychosocial remission) and a poor course (no symptomatic or psychosocial remission), to assess the impact of treatment adherence on the change in the functional and community integration status of patients (based on the occupation, independence level, and degree of disability variables), to assess the significance of premorbid (academic and social) adjustment in the symptomatic and functional remission and the community integration status of patients and to correlate the level of insight to the remission and integration status of patients.

During the 1990s, evidence began to emerge of the long duration of untreated illness prior to receiving treatment for patients with psychotic disorders. Studies across the world on first episode psychosis have consistently found an average of 1 - 2 years between the onset of psychotic symptoms and the start of treatment. Lengthy treatment delay has immediate implications such as unnecessary distress for patients and families, and may also compromise potential recovery when treatment is initiated.By understanding how and why substantial delays occur the investigators may be able to better design interventions to facilitate better earlier treatment. The components of DUP can be conceptualised as comprising 3 distinct intervals: help-seeking delay, referral delay and delay in mental health services. In this study the primary aim is to establish the level of DUP in nordland, and explore the components of this variable. Help-seeking delay will be investigated by interviewing patients presenting at the central mental health hospital in Nordland about their psychosis onset and pathways to care. Referral delay will be investigated by a questionnaire about the referral pratices among GPs in Nordland. Delays in mental health services will be investigated by focus group interviews with leaders and professionals at the 7 community mental health centers in Nordland. This knowledge is believed to be crucial for developing services that can reduce DUP and give this patient population earlier access to adequate treatment.

This prospective, multi-center, 12 weeks naturalistic NIS trial will be conducted in 25 hospitals in naturalistic treatment setting. There will be no experimental component associated with this study and all observational activities have to be part of routine care visit: baseline (week 0), week 4 and week 12.

Multicentre, retrospective observational cohort study based on LHU administrative databases aimed to described the pharmacoutilization of antipsychotics in patients affected by schizophrenia and bipolar disorder, the resource consumption and medication adherence. A sub analysis will be performed for those patients switching from Quetiapine IR to Quetiapine XR and comparing the periods before and after the switch.

This study will assess asenapine (Sycrest®) use in participants with bipolar disorder; comparison will be made to the use of risperidone (RISPERDAL®CONSTA®) and olanzapine (Zyprexa®). The occurrence of identified and potential clinically important risks will also be assessed.

The purpose of the study is to evaluate the outcome of treatment switch defined as an improvement in CGI-CB scale (Clinical Global Impression - Clinical Benefit).

The purpose of this study is to prospectively examine adherence to oral atypical antipsychotics in patients with schizophrenia. We are psrticularly interested in examining the level of agreement among self-report, physician impressions and objective measures of adherence. We believe that physicians, casemanagers, and clients significantly overestimate the level of adherence.

Pharmacological treatment of schizophrenia is still characterized by a certain proportion of patients who are resistant to common antipsychotics. Variability in individual response ranges from patients who experience complete or near complete symptom remission to a subset of patients who remain treatment-refractory despite extensive drug trials over years. The investigators propose to take advantage of the simultaneous acquisition of clinical and of intermediate phenotypes to ascertain the possible contribution of SNPs within putative causative genes to response to treatment with quetiapine XR.
