Filter by:The objective of the study is to evaluate the efficacy of raloxifene compared to placebo, as add-on to anti-psychotics in the treatment of post menopausal patients with schizophrenia.
This study is going to determine the efficacy, tolerability and safety of ziprasidone in 120 schizophrenic patients with depressive symptoms. The study will be carried out at 2 mental centers in China. Subjects will be required to attend the center at screening, baseline, Weeks 1, 2, 4 ,6 and 8 or early termination visit. At screening, patients underwent psychiatric and physical examination, standard lab tests, and an Electrocardiograph. At baseline, if they continued to be eligible, they began ziprasidone 20 mg twice daily. Depending on response and tolerability, ziprasidone could be gradually escalated to a maximum of 80 mg twice daily.
Use Huperzine-A, a herbal supplement normally used for treatment of Alzheimer's disease, to potentially improve cognitive dysfunction (memory problems) and functional capacity (ability to perform common daily tasks such as cooking, bathing, telephone, shopping) in people with schizophrenia.
Different compounds that might modify the glucose regulation in the central nervous system will be evaluated in healthy volunteers. Several examinations will be performed in order to get a detailed plan how these substances might work.
This prospective study examines the differences among several measures of adherence to antipsychotic medications in outpatients with schizophrenia. Adherence is assessed by using self-report, physician report, pill count and electronic monitoring. The rates of adherence/non-adherence with various tools will be manifested. The association between antipsychotic adherence/non-adherence and various clinical status, including psychotic symptoms, depressive symptoms, side effects, neurocognitive function and insight are analyzed. Participants are assessed at baseline during a visit to their outpatient clinic and followed up for 8 weeks.
The goal of our research is to check the levels of D-Serine, Glycine, and other Glutamatergic amino acids, in patients with First Psychotic Episode (FPE). These patients are in the early stage of the disease, treated with neuroleptics for short periods of time, and are usually hospitalized for the first time. The hypothesis of the research is that we will find low levels of Glycine and D-Serine in these patients. Following an Anti-psychotic treatment we will expect these levels to return to the norm, and that this correction will be accompanied by a reduction of positive and negative symptoms. In addition, we will check the D-Serine and Glycine levels in the plasma of first degree relatives of the patients and a group of healthy subjects. The results of this study might support the hypothesis that the Glutamatergic system in involved in the pathology of Schizophrenia from it's early stages. In addition, we will check the levels of Oxytocin and Estrogen in the plasma of patients in FPE. Our hypothesis is that we will find low levels of Estrogen and High levels of Oxytocin in this group of patients. The results of the study might support the hypothesis that Estrogen and Oxytocin are involved in the pathology of Schizophrenia from it's early stages.
In the current study we will study the effect of adding acupressure (shiatsu) to conventional therapy in treating individuals with schizophrenia.
The purpose of this study is to evaluate the effects of nicotinic alpha-7 MEM 3454 on P50 sensory gating in patients with Schizophrenia. The hypothesis is that MEM 3454 will normalize the P50 ratio. Data produced in this study will provide useful information regarding the value of P50 as an efficacy biomarker, and provide evidence for the optimal dosing of MEM 3454 for additional P50 studies.
This study will examine brain responses during sensory processing in patients with schizophrenia. It will examine the hypothesis that patients treated with clozapine will show decreased responses during sensory processing as compared to patients treated with risperidone.
Genetic etiology in schizophrenia is widely accepted. However, many chromosomal sites were shown to characterize the families of patients with schizophrenia. This is probably due to the high genetic heterogenity of this illness. Thus, it is important to investigate the genetic factor in relatively genetically homogenous populations. Many studies have indicate that Ashkenazy Jews show relative gentic homogenity. Indeed, the genes responsible for most Mendelian disorders of Jewish peoples have been identified. The study will apply genome-wide mutation screening methods to identify candidate allells in subjects of Ashkenazi Jewish ancestry with multiplex schizophrenia.
