Filter by:The purpose of this study is to examine the mood stabilizing and antipsychotic properties of quetiapine in the treatment of depression by comparing subjects who were randomly assigned to either quetiapine monotherapy, quetiapine and citalopram; or haloperidol and citalopram. We hypothesize that quetiapine monotherapy would have similar effects to the combination of a first generation antipsychotic plus an antidepressant for the treatment of a major depressive episode with psychosis.
The purpose of this study is to determine the safety and efficacy of risperidone monotherapy in the treatment of psychotic depression. We hypothesize that risperidone is as equally as effective as haloperidol plus sertraline for depression with psychotic features
To assess the effect of risperidone 2 mg daily (QD) on the differential sensitivity of 2 spatial working memory tests (the GMLT and MDR) in non-agitated, drug-naive patients suffering from first-episode schizophrenia/schizophreniform disorder.
The quantity and quality of inpatient services for persons with psychiatric illness have been enhanced in the last two decades. Following the enforcement of nationwide health insurance and the Physically and Mentally Disabled Citizens Protection Act, the financial pressure of medical care for psychiatric patients is relieved, and actions related to the protection of patients' human rights have been taken. Nonetheless, problems related to psychiatric illness are not limited to symptoms. Patients' daily functions are affected and it causes continuous pressure on the family. Currently, psychiatric care places more emphasis on inpatient services. Once the patient is discharged from the hospital, related psychiatric services are not widely available, which leads to symptom exacerbation, repeated hospital admissions, increased burden to the family, etc. A provision of continuous long-term care that meets the various needs of psychiatric patients is a critical issue in current psychiatric care. Based on a three-phase needs assessment model, the purpose of the study is to evaluate the needs of long-term care for psychiatric patients. The first phase will identify the current status of needs from the perspectives of patients and the family, psychiatric professionals, and the system. The second phase will identify the goals of long-term care for psychiatric patients. The goals will be identified by a nominal group, composed of experts related to the field of psychiatric long-term care. The third phase will determine the objectives of long-term care services for psychiatric patients. That is to determine the proper contents of long-term care services for the patients based on the goals identified in the previous phase. The three-phase needs assessment will be carried out in a two-year period. The results of the study will provide important information to the future planning of long-term care for psychiatric patients.
The Recognition and Prevention (RAP) Program is conducting a research study comparing an antidepressant, sertraline, alone versus in combination with a second-generation antipsychotic, risperidone, to evaluate their ability to reduce unusual thoughts, suspiciousness and other unusual experiences, to improve reasoning ability, memory, attention and social skills in adolescents.
This study will evaluate the effectiveness of a health management and supported rehabilitation intervention in treating serious mental illnesses in older people.
The purpose of this study is to examine the short - term effects of clozapine on alcohol use in persons with schizophrenia and an alcohol use disorder. The hypothesis is that clozapine will have greater efficacy in reducing alcohol use than other antipsychotic medications.
The purpose of this study is to determine whether the administration of omega-3 polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA), can be useful both to reduce coronary artery disease (CAD) risk and illness severity in clinically-stable patients with schizophrenia (or schizoaffective disorder), major depression or bipolar disorder (depressed phase) being treated with lipid lowering drugs (e.g., statins).
The aim of the following pilot study is to examine boredom in a community sample of adolescents and a clinical sample of adolescents. This is important in order to examine differences among healthy adolescents and adolescents with mental illness.
In this study we, the investigators at UMC Utrecht, intend to investigate changes in brain activation patterns using functional magnetic resonance imaging (MRI), in patients suffering from schizophrenia who are medication naive or off medication, before using medication and after 8 weeks of medication. Patients will perform a working memory task, a language task and a motor task while lying in the scanner. We hypothesize that the efficiency of the working memory system is reduced and that the lateralization of language is diminished in these patients, and that these functions will normalize after treatment.
