Active clinical trials for "Schizophrenia"

This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial of curcumin for the treatment of cognitive impairment in schizophrenia.The primary aim of this pilot trial is to provide an effect size estimate for the efficacy of curcumin in improving cognitive functioning in schizophrenia. Secondary goals are to determine the effect of curcumin over time on negative and positive symptoms, in association with inflammatory markers.

This trial attempts to evaluate the treatment efficacy of magnetic seizure therapy (MST) and its safety among schizophrenia patients. Half of the participants will be randomized to MST group, while the other half will be randomized to receive electroconvulsive therapy (ECT).

Youths diagnosed with early onset schizophrenia will demonstrate amelioration of auditory hallucinations after one week of twice daily treatment with transcranial direct current stimulation (tDCS).

Symptomatic treatment of the negative symptoms in schizophrenia (such as social withdrawal, affective flattening, poor motivation, and apathy) with medications and psychotherapy are almost non-existent, whereas treatment of the positive symptoms (hallucinations and delusions) has been more effective with psychotropic medications. The proposed research on human subjects using a non-invasive technology (such as repetitive transcranial magnetic stimulation [rTMS]) will provide efficacy data for treating negative symptoms. The hypotheses are that 1) Cerebellar stimulation will cause activation of thalamic and frontal cortical networks associated with attentional processes as a component of the "distracted" affect of schizophrenia; 2) Cerebellar stimulation will cause activation of the reticular activating system (RAS), and this will allow the "mutism", which is a negative symptom, to be partially improved.

Aim: To examine the efficacy of the combination of galantamine and memantine for the treatment of cognitive deficits in outpatients with schizophrenia. Hypothesis: A combination of galantamine and memantine will improve cognitive impairments in patients with schizophrenia. This is an open-label study to evaluate whether a six week course of galantamine ER and memantine XR is effective in improving the cognitive performance of patients with schizophrenia or schizoaffective disorder. The primary outcome measure will be the change in level of cognition as measured by the MATRICS Consensus Cognitive Battery (MCCB). The results of the MATRICS collaborative project recommended the need for standardized cognitive tests that better distinguish the different facets of cognitive dysfunction in schizophrenia. The MCCB will assess the following seven domains: attention/vigilance, reasoning and problem solving, processing speed, social cognition, verbal learning and memory, visual learning and memory, and working memory. The MCCB will be administered at baseline and at the end of the study. We will report total score and each domain score in the MCCB at baseline and six weeks.

To evaluate the efficacy and safety of cariprazine at a target dose of 4.5 milligram per day (mg/d) compared with placebo in prevention of relapse in patients with schizophrenia To evaluate the efficacy and safety of cariprazine at a target dose of 3.0 mg/d compared with placebo in prevention of relapse in patients with schizophrenia who were initially stabilized on a target dose of 4.5 mg/d

The purpose of this study is to test whether administration of levetiracetam (LEV), a commonly used anti-epileptic that alters neurotransmitter release, can reduce hippocampal hyperactivity in people with psychotic disorders. Specifically, the investigators will utilize two functional magnetic resonance imaging (MRI) techniques: 1) blood-oxygen-level-dependent (BOLD) contrast will assess activity with a visual scene processing task that engages the anterior hippocampus and 2) arterial spin labeling (ASL) will assess baseline activity. Previous studies in people with psychotic disorders have shown that the hippocampus is hyperactive and more activity correlates with worsening of clinical symptoms. Therefore, the aim of this study is to use an intervention to further understand the underlying mechanisms of the hippocampus in psychosis.

The purpose of the study is to determine whether addition of electroconvulsive therapy to antipsychotic treatment improves the mental health of patients with treatment-resistant schizophrenia.

This study aims to evaluate whether PF-02545920 is safe and effective in the treatment of sub-optimally controlled symptoms of schizophrenia during a 12-week outpatient treatment period. The study will use the Positive and Negative Syndrome Scale (PANSS) to measure change in symptoms for PF-02545920 from baseline compared to placebo.

Background: Surveys have shown that antipsychotic drug combinations are frequently prescribed. Amisulpride, an atypical antipsychotic agent, has low incidence of extrapyramidal symptom (EPS) but with high cost compared to sulpiride. The objective of the study is to compare the efficacy and safety of the 800-mg/d amisulpride and 400-mg/d amisulpride plus 800-mg sulpiride in the treatment of acute psychotic exacerbations of schizophrenia. Method: In this 6-week, double-blind, fixed-dose study, patients with schizophrenia are randomly assigned to amisulpride (800 mg/d) or amisulpride (400 mg/d) plus sulpiride (800 mg/d).The hypothesis is that the two treatment groups have the similar efficacy and safety, but different cost.
