Active clinical trials for "Schizophrenia"

The objective of the study was to study the effects of donepezil on cognition in patients with schizophrenia. The investigators conducted a 12-week, double-blind, placebo-controlled trial of donepezil as adjunctive treatment to antipsychotic drugs on patients with schizophrenia.

The aim of this project is to undertake a randomized placebo controlled trial of cognitive remediation therapy (CRT) that focuses on working memory training in a sample of community based patients with chronic schizophrenia or other psychoses. Cognitive deficits are a problem for many people with schizophrenia. This study will use computerized cognitive remediation training (which the participant can carry out at home) over a period of a few months.

This research will explore whether Quetiapine XR used primarily to treat psychosis may also cover for comorbid anxiety disorder and offer advantages in patients with schizophrenia and comorboid anxiety disorder. Preliminary data on pharmacological properties of Quetiapine and its metabolites and intuitive impression from our clinical experience lead to believe that Seroquel XR use in monotherapy may offer advantages over other antipsychotics in treating co-morbid anxiety disorder in patients suffering from schizophrenia. This open label switch study conducted in a schizophrenic population intends to verify this hypothesis.

Sorghum bicolor is a naturally growing plant which has been of health benefit to the people of West Africa who traditionally prepare its leaf for various nutritional and health reasons.The food and nutritional fact analysis showed that Jobelyn is rich in Carbohydrates, Protein, Dietary Fiber, Iron, Natural Vitamins like B12 and Vitamin C. It also contains Selenium, Omega 3,6 and 9 and other essential elements and fatty acids. Although the determinants of mental health are complex, the emerging and compelling evidence for nutrition as a crucial factor in the high prevalence and incidence of mental disorders suggests that diet is as important to psychiatry as it is to cardiology, endocrinology, and gastroenterology. Evidence is steadily growing for the relation between dietary quality (and potential nutritional deficiencies) and mental health, and for the select use of nutrient-based supplements to address deficiencies, or as monotherapies or augmentation therapies. There is currently strong advocacy for the recognition of diet and nutrition as central determinants of both physical and mental health.Its anti-inflammatory and haematocrit boosting properties have been well documented though the precise mechanism of action is still largely unknown. Its use has recently been extended to the field of mental health where findings in animal study suggest it could be of help in relieve of psychosis. The need for this study is therefore aimed at investigating the effect of this drug in patients with schizophrenia which is the prototypical psychotic disorder.

The purpose of this study is to examine whether auricular acupressure is effective in reducing body weight, waist circumference, or lipid profile.

In this study we want to find out whether MS14 - a herbal drug- can help Schizophrenia patients or not.

This study will provide information regarding dopamine D2/D3 occupancy related with clinical/adverse effects in older people with schizophrenia and schizoaffective disorder. The results of this study will also show an appropriate dose range in order to evade undesirable adverse effects while deriving therapeutic effects, which will directly serve to guide physicians in clinical practice. Furthermore, the findings of this study will elucidate mechanisms underlying older people's increased sensitivity to antipsychotic drugs. In addition, the contribution of D2 and D3 in mediating antipsychotic response will be contrasted, using 2 radiotracers, which has never been tested in an older population. The hypotheses are as follows: First, clinical response (i.e., a ≥ 20% decrease in the Brief Psychiatric Rating Scale total score) will be achieved in older patients with occupancy that is lower than the threshold of 60% in historical young controls. Second, prolactin elevation and EPS will be detected in older patients with occupancies that are lower than the thresholds of 72 and 78% reported in historical young controls. Third, dopamine D2 receptor occupancy will be inversely correlated with subjective well-beings. Fourth, the binding potential and receptor occupancy will be at least 20% lower with [11C]-(+)-PHNO than with [11C]-raclopride in the caudate/putamen. Fifth, the binding of [11C]-(+)-PHNO in the globus pallidus will be higher than that of [11C]-raclopride.

An individual's genetic make-up is known to determine their response to antipsychotic medication. Genetic markers that determine efficacy and side effects of medication may be identified and used to predict treatment outcome. The study is a naturalistic study of routinely prescribed antipsychotics using outcome measures undertaken as part of the routine clinical care of the cohort. These clinical data are linked with genetic information obtained from DNA and RNA from blood samples undertaken as part of the study. No alteration is made to the subjects treatment regime or medication. The study is a two stage investigation: The first stage involves the collection of a databank of clinical information and blood samples for DNA and RNA extraction from patients treated with antipsychotic medication. The second stage is a molecular genetic investigation of treatment-related genetic factors that may contribute to response prediction and predisposition to side effects. From these genetic studies pharmacogenetic prediction tests will be validated and/or developed.

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.

In our study we aim to examine the effect of SSRI augmentation on negative symptoms and cognitive function in schizophrenia patients as well as to examine the effect of SSRI augmentation on the RNA and protein products in peripheral mononuclear cells (PMC). Finally, we aim to relate changes in PMC elements to changes in clinical symptoms and cognitive function. Our study hypotheses are that SSRI augmentation of anti-psychotic treatment in schizophrenia patients will improve negative symptoms as well as cognitive symptoms and that this improvement will be related to biochemical changes identifiable in PMC elements.
