Filter by:Schizophrenia is still remained one of the disabling disorders despite progress in treatment of mental disturbances. Ten to thirty percents of patients have a little or no benefit from treatment with all kinds of antipsychotics using adequate dosages and duration. Treatment of these patients has remained a persistent public health problem since medication-resistant patients are often highly symptomatic. Curcumin is one of the main curcuminoids isolated from this perennial herb. It possesses a variety of pharmacological activities, including anti-inflammatory, antiproliferative, antioxidant, and neuroprotective effects and crosses the blood-brain barrier. The purpose of our suggested study is to examine the efficacy of curcumin as add-on the conventional antipsychotic psychopharmacotherapy in chronic schizophrenia patients.
The purpose of this study is to determine the relationship between ITI-007 dose, plasma levels and brain receptor occupancy in patients with stable schizophrenia.
The primary objective of the study is to evaluate the efficacy of DSP-5423P compared with placebo in patients with schizophrenia.
The objectives of this 15-day study are: 1. To compare steady-state trough plasma concentrations of clozapine and its metabolite norclozapine when given once daily and twice daily (at the same total daily dose) 2. To determine if frequency of clozapine administration has an effect on: 1. Symptoms of schizophrenia 2. Adverse effects of clozapine 3. Fasting blood glucose, lipids, creatinine, and urea 4. Weight and waist circumference
This proposed randomized controlled trial will test the effectiveness of a problem-solving based bibliotherapy program (PSBPF) for Chinese family caregivers in schizophrenia spectrum disorders. A repeated-measures, three-group design will be used to evaluate and compare the effects between two treatment groups (PSBPF and behavioral management group) and routine outpatient service (control group) for 150 randomly selected family caregivers of outpatients with schizophrenia-spectrum disorders over a 18-month follow-up.
The study will be conducted as a randomized, double-blind, parallel-group, placebo-controlled, multi-center study in patients diagnosed with schizophrenia having an acute exacerbation of psychosis.
This study compares aripiprazole once-monthly injection to standard of care oral antipsychotic medication in non-adherent outpatients with schizophrenia to see which treatment helps people take their medicine more regularly and have more positive outcomes. It is hypothesized that non-adherent schizophrenia outpatients receiving aripiprazole once-monthly will be more likely to respond and have lower symptom severity over 3 months of treatment than those receiving standard of care oral antipsychotics.
The objective of the study is to investigate the efficacy, safety and tolerability of four different doses of BI 409306 once daily compared to placebo given for 12 weeks in patients with schizophrenia on stable antipsychotic treatment.
Schizophrenia and bipolar disorders are major public health problems. The second generation anti-psychotic drugs have efficacy for both positive and negative symptoms and a favorable risk profile as far as movement disorders. However, these drugs are associated with clinically significant weight gain and metabolic effects. The underlying mechanisms of these side effects are unclear, however in our preliminary studies with schizophrenic patients on atypical anti-psychotic drugs, we found that weight gain and vitamin D deficiency was present in about 50% of this population. Given the considerable heterogeneity among the patients on atypical anti-psychotics and potential for weight gain in vitamin D-deficient states, we propose that patients with schizophrenia who gain weight on atypical antipsychotic medications are vitamin D-deficient. This hypothesis will be tested in patients with schizophrenia receiving second-generation anti-psychotic drugs for a minimum duration of 4 months. Specific Aim: We predict that the patients with schizophrenia, who gain weight with antipsychotic treatment, are vitamin D-deficient compared to the patients who do not gain weight. We will examine circulating levels of serum 25(OH)D, mRNA transcripts and protein expression of vitamin D receptor (VDR) and the enzymes, CYP24A and CYP27B, in the white blood cells of the subjects and correlate with BMI and the blood levels of leptin and adiponectin.
This is a randomized controlled 6-month trial of the efficacy of a novel intervention combining neuroplasticity-based cognitive training with aerobic exercise, compared to the same systematic cognitive training alone. The primary treatment targets are overall cognitive deficit level and independent living skills. The investigators hypothesize that combining neuroplasticity-based computerized cognitive training and neurotrophin-enhancing physical exercise will produce large cognitive and functional improvements, even relative to cognitive training alone. Adding aerobic exercise to a cognitive training program will have the additional benefit of helping to ameliorate medication side effects, reduce the risk for developing metabolic syndrome, and help to prevent the deterioration in physical health that usually follows the onset of schizophrenia and its pharmacologic treatment. The investigators target the period shortly after a first episode of schizophrenia to maximize the generalization of cognitive improvement to functional outcome, before chronic disability is established.
