Active clinical trials for "Schizophrenia"

The goal of this research is investigating the heart rate changes in schizophrenic and bipolar patients under the medication of aripiprazole and quetiapine. In the mean time, we are hoping further investigating the interrelationship of medicine dosage and heart rate change, in order to acquire the best relationship both effectiveness as well as safety in acceptable heart rate change of clinical suggestion.

The aim of the study is to examine whether the efficacy of psychoeducation in patients with schizophrenia or schizoaffective disorders is dependent on their cognitive performance level and if a preceding cognitive training can enhance the therapeutic effects of psychoeducation

To establish the proof of concept that MEM 3454, used as add-on pharmacotherapy, is a safe and effective treatment in patients with cognitive impairment associated with schizophrenia (CIAS).

N-methyl-D-aspartate receptor (NMDAR) agonist, added to classical or atypical antipsychotic medication, has reduced negative, depressive, and cognitive symptomatology. We will be investigating the effect of D-serine, (DSR), a selective and potent NMDAR agonist, as monotherapy for treatment resistant schizophrenics. 40 subjects on stable doses of risperidone will be randomized under double-blind conditions into a treatment group, which will receive D-serine 2100 mg, or a control group, which will continue to receive risperidone. Treatment will continue for 14 weeks. Symptoms and side effects will be rated biweekly with the CGI, PANSS, BPRS, SAS, AIMS, and UKU. Before and after the trial subjects will undergo neuropsychological assessments. Baseline and post-trial levels of amino acids relevant to glutamatergic neurotransmission (glutamate, glutamine, aspartate, glycine, serine, alanine) will be assessed. The primary outcome measures of the study will be the PANSS total scores and the positive and negative symptom cluster scores.

Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.

In this study we intend to compare the effect of Sertindole to that of Risperidone on cognitive impairment in schizophrenia. Hypothesis: Sertindole will be as effective as Risperidone for treating cognitive impairment in schizophrenia and with fewer side effects.

Antipsychotic drugs can cause a clinically relevant hyperprolactinemia due to blocking the dopamine receptors in the pituitary.Schizophrenic patients suffering from a neuroleptic-induced hyperprolactinemia will be examined endocrinologically. Adverse drug effects and diagnoses will be confirmed by measuring hormones.

This project seeks to evaluate the feasibility and effectiveness of combining cognitive remediation and Supported Employment Program (SEP) services to improve work outcomes in people with a serious mental illness who have been unable to benefit from vocational services (i.e., acquire or maintain a job). Cognitive remediation involves treating and improving cognitive impairments, such as memory (e.g., short-term and working memory), attention span, or problem solving skills. It is hypothesized that cognitive remediation will significantly improve peoples' employment outcomes in a supported employment program.

The goal of the present study is to evaluate the effect of D-serine, added to antipsychotic treatment, on negative and cognitive symptoms in schizophrenia. The investigators are hypothesizing that D-serine will improve cognitive functioning and negative symptoms.

The main object of this study is to evaluate the efficacy of equine assisted therapy on substantial and so far unsatisfactorily treatable symptom complexes in patients with schizophrenia.
