Active clinical trials for "Schizophrenia"

In the present study, we investigate healthy subjects and schizophrenic patients who frequently show very low attentional capacity with functional magnetic resonance imaging (fMRI) and electrophysiology (EEG) during attention-requiring tasks to assess the level of attentional network activity.

Representative payees, mostly family members, manage Social Security Administration funds of more than one million people with psychiatric disabilities. Although studies show payeeship can be used coercively, foster dependency, reduce work incentives, lead to family conflict and even violence, there has been little systematic research on how to lower these significant barriers to community integration. The investigators' long term goal is to promote recovery among adults with psychiatric disabilities who have payees by reducing downsides associated with what has been called "the nation's largest guardianship system." The investigators' objective in the current application is to evaluate a pilot-tested, stakeholder-informed intervention that is grounded in principles of psychiatric rehabilitation and encourages consumers with psychiatric disabilities and their family members to collaborate within the representative payee arrangement.

This trial is designed to determine if administering repetitive transcranial magnetic stimulation (rTMS) simultaneously to two sites in the temporal lobes, one on the left and one on the right, produces greater improvements in "voices" and other symptoms of schizophrenia compared to rTMS given to just one site in the temporal lobes.

This study will develop and evaluate the effectiveness of a self-management program for adults living with both schizophrenia and a co-occurring medical condition.

The primary purpose of the study is to investigate whether an intensive educational intervention can reduce the use of antipsychotic polypharmacy. It is hypothesised that the use of antipsychotic polypharmacy is, in some degree, dependent on non-patient related factors.

The primary aim of the project is to examine the efficacy of the Psychiatric Rehabilitation Weight Loss program in reduction of weight and body mass index (BMI.

This study will determine whether using a pager improves medication adherence in people with schizophrenia.

Cigarette smoking decreases life expectancy, causes devastating health complications, and costs society billions of dollars each year. These untoward consequences are especially pronounced among persons with schizophrenia (SCZ) because approximately 80% to 95% of this group smokes cigarettes. These high prevalence rates underscore the need for research investigating the determinants of smoking in patients with SCZ. Several researchers have observed that nicotine improves specific symptoms of SCZ including negative symptoms, negative affect, and cognitive deficits. This has led to the hypothesis that patients with SCZ smoke in an attempt to self-medicate. However, the mechanism(s) by which nicotine has its positive effect on symptoms remains unclear. The current proposal posits that neural inhibition (NI) is a physiological mechanism of this effect, while variation in the alpha-7-nicotinic receptor subunit gene (CHRNA7) represents the genetic underpinnings of these processes. The proposed study will assess NI and symptom improvement after acute administration of nicotine to both smokers and nonsmokers with SCZ. In addition, NI and CHRNA7 variation will be tested as predictors of patients' ability to reduce/quit smoking following smoking treatment. These data may lead to the development of new pharmacological strategies for treating the symptoms of SCZ and new methods for assisting these patients to quit smoking.

This single center, open-label study will evaluate the PK-PDE10A Enzyme Occupancy Relationship of RO5545965 after a single dose in healthy male volunteers by positron emission tomography (PET).

The purpose of this study is to measure and contrast implicit and explicit learning performance in patients with schizophrenia relative to young and elderly healthy volunteers.
