Active clinical trials for "Schizophrenia"

Studies using repetitive transcranial magnetic stimulation (rTMS) as a treatment for refractory auditory hallucinations (AH) in schizophrenia have shown promise. The majority of studies have examined the effect of low frequency left-sided stimulation (LFL) (i.e., 1 Hz) to the temporal parietal cortex (TPC). Priming stimulation (6 Hz) prior to LFL stimulation (hereby simply referred to as priming) has been shown to enhance the neurophysiological effects of LFL rTMS alone and, as such, may lead to greater attenuation of AH. Therefore, this study evaluated the efficacy of priming rTMS and LFL rTMS, compared to sham, applied to the TPC in patients with schizophrenia experiencing refractory auditory hallucinations (AH).

Being obese is a common problem for people with schizophrenia. People with schizophrenia are more likely to be overweight compared to the general population. Being overweight is a major risk factor for developing type II diabetes. Approximately 15% of people with schizophrenia have type II diabetes. People with type II diabetes have problems with their body's insulin. Insulin is a hormone produced by the body to control blood sugar level. Obesity and type II diabetes are strong risk factors for heart disease. In type II diabetes the body does not respond to insulin correctly. Obesity, type II diabetes, and insulin resistance are all common states of inflammation. Inflammation is a reaction by the body to irritation, injury, or infection. Salicylates are non-steroidal anti-inflammatory drugs. Aspirin is an example of a salicylate. These drugs work by decreasing the level of inflammation in the body. Salicylates have been shown to decrease inflammation and improve the body's response to insulin. Improving the body's response to insulin and decreasing inflammation could possibly reduce the risk of developing type II diabetes. Salicylates have been known for years to be effective for the treatment of diabetes. Salicylates increase the body's response to insulin causing blood sugar levels to decrease. Many salicylate drugs have side effects including stomach irritation and increased risk of bleeding. The drug for this study is called salsalate and is different from other salicylates. Salsalate has a lower bleeding risk than aspirin. Salsalate has been used to treat arthritis and has been shown to be safe. There have been no studies using salsalate in people with schizophrenia. The purpose of this study is to gain experience in the use of salsalate in people with schizophrenia. The study would be a pilot study to obtain preliminary data. The study would be a 6-week study where everyone in the study would receive the drug salsalate. The participants in the study will have tests of baseline symptoms of schizophrenia, a physical exam, EKG (to check heart function), and a side effect checklist for possible side effects from salsalate. The study will also have some blood drawn to measure blood sugar levels, insulin levels, and inflammatory markers.

To investigate dose-response of Rapid Acting Intramuscular Olanzapine in Agitated Patients with Schizophrenia

This is an eight-week open-label randomized parallel group clinical trial focusing on the comparison of risperidone alone with risperidone plus valproate among hospitalized adult patients diagnosed with schizophrenia who also exhibit problems with hostility. Patients may have already been receiving risperidone or valproate (but not both) at study entry. Patients not receiving valproate at study entry were randomized to receive either risperidone alone or risperidone with valproate. For patients already receiving valproate at study entry, their antipsychotic medication(s) was switched to risperidone, and they were followed for a four-week lead-in period prior to baseline assessment and randomization to receive risperidone alone or continue with risperidone and valproate. We hypothesized that risperidone alone has an antiaggressive/antihostility effect, and that this effect is augmented by the co-administration of valproate.

Assess the efficacy of a fast titration of quetiapine to the current titration approved by the regulatory authorities. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.

The purpose of this study is to prove safety and efficacy of aripiprazole.

This study will determine the effectiveness of oral risperidone versus long-acting injectable risperidone in treating people with first-episode schizophrenia.

This study is a double-blind, placebo-controlled trial of the nicotinic receptor agonist, galantamine, for the improvement of memory and attention in people with schizophrenia and schizoaffective disorder. Twenty subjects on a stable dose of antipsychotic medications receive galantamine or identical placebo tablets for 8 weeks. Adverse events are screened for every week. Tests of memory, attention, and reward responsivity are performed at baseline and afer 8 weeks on medication. Clinical scales rating psychiatric symptoms are performed at the beginning, middle, and end of the trial.

The purpose of the study is to estimate drug preference of stable schizophrenic patients who will be treated with olanzapine orodispersible tablets for 6 weeks then with olanzapine tablets for 6 weeks and vice-versa.

This study will evaluate the effectiveness of a lifestyle intervention in increasing physical activity and reducing disease symptoms in sedentary adults with schizophrenia.
