Filter by:Aim was to detect EEG complexity in a specific group of patients to contribute to the discussion whether schizophrenia is associated with increased or decreased complexity. We included the EEG recordings of patients with a diagnosis of schizophrenia. We hypothesized that chronic residual schizophrenia is characterized by decreased complexity in EEG.
The aim of the study is to compare the effectiveness of the meta-cognitive training (MCT) for schizophrenia against treatment as usual (TAU) among patients who attends community support groups. 4 weeks of MCT will be administered for patients two times per week. MCT consists of well structured cognitive behavioral therapy interventions. MCT will be administered according authors recommendations. All participants will be assessed at baseline (T0) and up to one week after the MCT intervention (T1, 4-5 week of the study).
A review of the amount of drug in your blood over time.
It is important that individuals with serious mental illness make informed choices among alternative healthcare treatments based on their preferences. However, at present, individuals' preferences are often not being elicited, nor used to guide which treatments are made available. In this pilot project, the investigators implement and evaluate a computerized method for assessing treatment preferences of individuals with schizophrenia. The investigators use weight management treatments for this initial test of the system. If this assessment method is found to predict treatment use and satisfaction, it can be used to guide implementation of treatments that improve outcomes while meeting individuals' preferences.
This 3-part dose titration study will assess MK-8189 safety, tolerability, pharmacokinetics (PK), and central nervous system activity. Part 1 (Panels A and B) will assess MK-8189 administered as monotherapy in participants with schizophrenia. Part 2 (Panel C) will assess MK-8189 administered as add-on to atypical antipsychotic treatment in participants with schizophrenia. Part 3 (Panel D) will assess monotherapy with MK-8189 in healthy participants, including those of Japanese descent. The primary hypothesis is that there is at least one dose of MK-8189 that is generally safe and well-tolerated which will have the desired PK parameters in participants with schizophrenia.
Spatial working memory (ability to remember where objects are in space) is impaired in patients with schizophrenia. It is thought that this impairment occurs due to problems with the chemical messenger (neurotransmitter), glutamate, and the N-methyl-D-aspartate (NMDA) glutamate receptor, particularly in the hippocampal brain region. NMDA receptor activation leads to increases in the release of the second messenger Nitric Oxide. Impaired NMDA receptor function would therefore be predicted to lead to reductions in Nitric Oxide production. Recent work suggests that a drug, sodium nitroprusside, which releases nitric oxide, enhances some aspects of cognition in schizophrenia (specifically related to negative symptoms). In this study, the investigators will test the hypothesis that sodium nitroprusside improves spatial working memory in patients with schizophrenia. 15 patients will receive sodium nitroprusside, and 15 will receive a nonactive compound (placebo). Their performance on a spatial working memory task will be tested before and after administration of sodium nitroprusside or placebo.
Auditory Hallucinations (AH) are experienced by 50 to 70% of subjects with schizophrenia. Almost a quarter of patients are medication resistant to such symptoms. The application of rTMS at low frequency in the left temporoparietal cortex reduces AH. A pilot study reported successful treatment of AH with high frequency rTMS. rTMS (20Hz) should be a shorter and an easier treatment for out-patients with schizophrenia compared to low stimulation treatment.
To evaluate the pharmacokinetic (PK) characteristics after multiple oral administration of 40 mg lurasidone in healthy Chinese subjects. To evaluate the safety and tolerance after multiple oral administration of 40 mg lurasidone in healthy Chinese subjects.
To evaluate the pharmacokinetic (PK) characteristics of lurasidone after single oral administration of different doses in healthy Chinese subjects. To evaluate the safety and tolerability of lurasidone after single oral administration of different doses in healthy Chinese subjects.
This study will compare Cognitive Behavioral Social Skills Training-Compensatory Cognitive Training (CBSST-CCT) to a goal-focused supportive contact group to see which intervention better improves symptoms and functioning in people with schizophrenia.
