Active clinical trials for "Schizophrenia"

The purpose of this study is to determine the effect of bifeprunox or risperidone on the body weight of patients with schizophrenia.

This is the sister study to the BMS "Cognitive Improvement with Aripiprazole (Abilify)" study (LSUHSC #H04-022). Evaluation of cognitive ability in patients with schizophrenia or schizoaffective disorder both before and after a switch from risperidone, olanzapine, or risperidone Consta injections to aripiprazole may reveal some of the cognitive changes that correlate with the improved response, better side effect profile, and effects on other components of the negative symptom array. Further, examination of brain functional activity using functional magnetic resonance imaging (fMRI) during an episodic memory task, as well as behavioral performance and associated electroencephalographic (EEG) data of working memory and intermediate term verbal memory collected with the Sustained Attention and Memory Brain Function Test (SAM-BFT), may also provide data showing the neural correlates of these changes in cognition.

The present study will specify and delineate the separate components of cognitive deficits and examine the effects of adjunctive cholinergic augmentation on these cognitive deficits as well as psychopathology in schizophrenic patients treated with an antipsychotic compound with no aberrant binding affinity for the cholinergic receptor system. The hypothesis is that cholinergic augmentation using donepezil will improve cognitive deficits, sensory gating deficits, and psychopathology in schizophrenic patients treated with an atypical antipsychotic (ziprasidone).

The purpose of this study is to show that amantadine might help to reduce the side effect of the medications which are prescribed to treat schizophrenia or schizoaffective disorder. High level of hormone prolactin, or hyperprolactinemia, is one of the side effects which might be developed in patients treated with the paliperidone ER or risperidone Consta. High level of prolactin might stimulate breast development, might decrease sexual desire (libido). The goals of this study are to demonstrate that amantadine lowers prolactin levels, decreases side effects, and improves psychiatric symptoms.

The purpose of this study is to provide access to bifeprunox for patients, who have completed previous studies with bifeprunox, and require continued treatment with bifeprunox, other treatment not being adequate. A further purpose is to investigate the safety and side-effects of bifeprunox during long-term treatment.

This study will examine the physical responses brought on by clozapine and haloperidol in people experiencing their first episode of schizophrenia.

This study will be conducted to evaluate the efficacy, safety, and tolerability of GWP42003-P versus placebo in participants with schizophrenia experiencing inadequate response to ongoing antipsychotic treatment.

This 12-month study will evaluate the efficacy of aripiprazole lauroxil compared to oral aripiprazole in preventing the re-emergence of psychotic symptoms in patients with a recent onset of schizophrenia.

This is a randomized, placebo controlled, double-blind clinical trial. The investigators aim to examine the safety and efficacy of repeated transcranial magnetic stimulation (rTMS) for the treatment of auditory verbal hallucinations (AVH) in patients with schizophrenia who are not taking antipsychotic medication. The investigators employ a novel, accelerated protocol with only four sessions of low-frequency rTMS in one day. The effects of this accelerated protocol will be compared to the sham stimulation. Additionally, the investigators will examine the effects of rTMS on a neurophysiological level by evaluating mechanism of action in the temporo-parietal lobe by means of functional magnetic resonance imaging.

An Open-label, Multi-center, Longitudinal, Within-subject Comparison Study to Evaluate the Effects of Aripiprazole Once Monthly in Subjects with Schizophrenia on 30-, 90-, and 180- day Re-hospitalization Rates Following Hospital Discharge Compared with Retrospective Re-hospitalization Rates while on Oral Antipsychotic Medication.
