Active clinical trials for "Schizophrenia"

Schizophrenia patients in comparing to normal controls show decreased ability to identify objects with decreased level of fragmentation, a task that is associated with magnocellular pathway function.

Clozapine remain the drug of choice for treatment resistant schizophrenia and up to 60% of patients not responding to other antipsychotics will respond to clozapine. However, the use of clozapine is restricted due to the risk of agranulocytosis and consequently the need for mandatory hematological monitoring. CHEMPAQ XBC is a point-of-care device that can be used in patients home and analyze WBC and granulocytes by a single capillary blood drop. This study aims to investigate whether this new procedure increases the acceptability of clozapine

Briefly, this multisite study is designed to identify endophenotypes (i.e., heritable biomarkers) associated with either schizophrenia or bipolar disorder alone, or both together. The subsequent genetic analyses will search genomic loci and candidate genes associated with each of the independent endophenotypes. This is a five site study that is slotted for NIMH funding.

This proposed 2-year questionnaire study examines views and attitudes regarding health risks of cigarette smoking, smoking patterns and motivators for cessation in smokers who suffer from schizophrenia compared to a sample of smokers without a major psychotic disorder.

the primary purpose of the study is to observe symptoms control in schizophrenia for 6 months in patients treated with Seroquel XR. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.

There is a differences in voice frequency of schizophrenic patients compared to patients with other mental diseases and compared to mentally healthy people.

The basic hypothesis of this trial is that forgetfulness and failure to establish a routine that facilitates medication adherence are prominent reasons for non-adherence. Daily use of the SMS text messages is designed to enhance patient adherence with medication by promoting daily routine and demonstrate the feasibility of using SMS technology within normal clinical practice in The Netherlands. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.

The purpose of the study is to find and follow-up the metabolic syndrome parameters on patients administering atypical antipsychotics.

The objective of this study is to explore the longitudinal course of self-disturbances (SD) in schizophrenia. The main aim of the study is to investigate, in a 6-7-year follow-up of a representative sample of patients with first-episode schizophrenia, bipolar disorder and other psychoses. The overall aim is to expand our knowledge about the role of SDs in psychotic disorders. Increased knowledge here will aid diagnosis and treatment. The current study is a seven year follow-up of this representative cohort, with baseline measures of SDs and a comprehensive clinical and neurocognitive assessment battery.

The importance of stress as a possible deteriorating factor for schizophrenic patients is well documented. However, this notion is based on subjective experience and retrospective psychological analysis. A novel method of measuring cortisol using hair has a proven correlation to subjective stress in non-clinical as well as psychiatric clinical populations. This pilot study will attempt to assess the use of cortisol hair level, as a marker of stress, to predict clinical deterioration in schizophrenic patients.
