Active clinical trials for "Psychotic Disorders"

Patients who suffer from diseases of the schizophrenia spectrum are frequently burdened by weight gain. Sport programs have been shown to improve somatic and psychological health. However, the motivation to participate in sports therapy is usually impaired due to illness-related factors such as anhedonia and negative symptoms. Previous attempts to increase participation in sports therapy have used psycho-educational and behavioral attempts that require a lot of resources. In this study the investigators will use a brief method developed in experimental social psychology to build up implementation intentions. This method has been shown to improve psychological test performance in schizophrenia patients but has never been used in a clinical context. In two psychiatric hospitals, in-patients with schizophrenia who have been examined by a medical doctor, for whom any medical concerns for sports therapy participation have been excluded and who declared their motivation to participate in an existing standard sports exercise program will be recruited for the study. After information on the study and signing of an informed consent patients will be randomly assigned to two treatment conditions. In the control condition, the main therapist will individually deliver a 10-minute psycho-education on the helpfulness of sports to improve the health; this will be repeated in a shorter form in the regular individual treatment sessions over the following weeks. The intervention condition will use a structured procedure of the same duration to build up implementation intentions to participate in the sports therapy. The implementation intentions will briefly be repeated and updated in the following session. Primary outcome variables will be percentage of attended sport therapy sessions, persistence and compliance. Secondary outcome variables will be Body Mass Index. As confounding variables the investigators will assess amount of anti-psychotic medication in Chlorpromazine equivalents, negative and depressive symptoms, usual sport activities and cognitive impairments. The investigators expect that building up implementation intentions will increase participation, persistence and compliance of the patients in the sports and exercise therapy program compared to the patients who just have received psycho-education.

The aim of this randomized, double-blind study is to verify the hypothesis that clozapine monotherapy is as efficient as a combination of clozapine and olanzapine therapy in treatment-resistant schizophrenia. A third of schizophrenia patients are non -responders to medications used nowadays. These patients are usually treated with clozapine, but a large proportion of patients don't recover sufficiently. Therefore, these patients are treated with combination of two or more drugs to achieve better treatment results. Until now the scientific evidence has been insufficient to assess the utility of polypharmacy. The aim is to study during 2009 with voluntary patients, if there is any benefit of olanzapine augmentation compared with pure clozapine monotherapy. During the study the patients are not exposed to any additional intervention. The intervention in this study is just to reduce the previously used polypharmacy. Methods: This study lasts for 24 weeks. Participants (30) are randomized in one of two alternative interventions (A or B) before the study. After 12 weeks the intervention arms cross over (from A to B and from B to A). Group B: In addition to clozapine, the participants receive their normal dosage of olanzapine (=the same as on the hospital ward) for 12 weeks, next the decreasing dosage of olanzapine for four weeks and subsequently placebo for 8 weeks Group A: : In addition to clozapine the participants receive the decreasing dosage of olanzapine for four weeks, next placebo for 8 weeks, after that the increasing dosage of olanzapine for four weeks and subsequently the normal dosage of olanzapine for 8 weeks The response for the medical treatment is assessed by Clinical Global Improvement Scale (CGIS) and Global Assessment of Functioning (GAF) -scale. The primary outcomes are GAF and modified CGIS during the parallel phase of the study (the first 12 weeks). The second phase (the last 12 weeks) of the cross-over study is used in the secondary analysis. The use of additional medication (such as benzodiazepines) is used as a secondary outcome measure.

The study will determine if individuals with co-occurring bipolar disorder and alcohol dependence report reduced alcohol consumption, improvement in mood symptoms, and cognitive performance if treated with lamotrigine plus their usual mood stabilizing medications relative to subjects treated with placebo plus usual mood stabilizing medications over a 16 week period.

This study will assess whether olanzapine and/or risperidone affect the way the human body uses sugar in the blood.

Four-month trial of pregnenolone or placebo, as an additional medication, to treat negative symptoms and cognitive decline in schizophrenia. After four months the scores on the negative symptom scale should be lower and the scores on the cognitive tests should be higher than they were at study entry, compared with people who do not take any additional medication.

The primary purpose of this study is to determine whether subjects with psychotic major depression benefit from adjunctive treatment with Org 34517. Two doses of Org 34517 will be compared to placebo in this international multicenter study. The duration of this trial is 6 weeks.

As many as 75 percent of patients with schizophrenia have difficulty taking their oral medication on a regular basis. This may lead to worsening of symptoms. Clinicians commonly respond to these problems by adding adjunctive medications, despite the absence of systematic studies that support such practices. It is possible, however, that in many of these cases, the unstable course and/or unsatisfactory treatment response reflects incomplete adherence with the originally prescribed oral antipsychotic, rather than a need for adjunctive medications. This study will examine whether switching patients who demonstrate an unstable course and/or an unsatisfactory clinical response to a long-acting injectable preparation as the primary antipsychotic may enhance medication adherence and improve outcomes.

This is a post-market surveillance, and the treatment to patients will be depended upon the decision based on physician's clinical judgment. The health profiles during the switching period, after 12 weeks short-term use, and after 52 weeks long-term use of aripiprazole will be recorded and evaluated.

The major objective of this proposal is to test the hypothesis that the addition of divalproex sodium to an atypical antipsychotic drug other than clozapine will significantly improve: a) cognition; and b) psychopathology (positive, negative, and mood symptoms) in a double-blind, randomized trial of 6 weeks duration in patients with schizophrenia or schizoaffective disorder.

The purpose of this study is to compare ziprasidone (Geodon) monotherapy for the treatment of psychotic major depression (PMD)with an antidepressant/antipsychotic combined therapy.
