Filter by:The purpose of this study is to investigate the effects of flexibly dosed Brexpiprazole monotherapy in the improvement of early-episode schizophrenia through the assessment of social functioning, efficacy, and tolerability. Early-episode schizophrenia is defined as episodes occurring ≤ 5 years after the onset of the first episode.
This is an exploratory study in Egypt that will combine a treatment trial among early course schizophrenia (ECSZ) patients with key analyses suggested by rodent studies. Specifically, the study will test the provocative results from animal studies indicating an impact of Toxoplasma Gondii (TOX) exposure on novelty seeking. The study will also test whether exposure to TOX is associated with other cognitive and behavioral changes, as well as changes in overall social function. We will also explore the relative efficacy of Sodium Valproate (Depakote, DEP) in improving clinical and overall social function among TOX exposed and unexposed patients. Hypotheses 1. At baseline, TOX exposure is associated with increased novelty seeking, clinical severity, and impaired cognitive and overall social function in patients with SZ. 2. Adjunctive DEP treatment improves clinical symptoms, cognitive and social function in SZ, particularly among TOX exposed SZ patients. 3. Exploratory hypothesis: adjunctive DEP reduces serological indices of TOX infection (VIP and TH levels).
Previous research has suggested central nervous system inflammatory activity to be critically involved in disease development and progression in schizophrenia, with a complex interplay of inflammatory mechanisms leading to the development of brain abnormalities and medical symptoms related to schizophrenia. However, the mutual interactions of different inflammatory pathways and their relation to disease course have not been sufficiently studied. This study therefore aims to explore the interaction of neuroinflammatory mechanisms in patients with schizophrenia and to assess whether the inflammatory activity in schizophrenia is state-dependent and occurs mainly during psychotic episodes.
The primary aim of the study is to determine the efficacy of adjunctive valacyclovir, in comparison to placebo, to improve visual (Brief Visuospatial Memory Test) and working (composite score of the Spatial Span and Letter Number Span tests) memory in individuals who are HSV-1 positive and early in the course of schizophrenia. We hypothesize that individuals who are HSV-1 positive, but not those who are HSV-1 negative, will demonstrate significant valacyclovir efficacy for visual and working memory.
The purpose of the study is to measure the sensitivity of NCFHEB binding to changes in endogenous acetylcholine levels in healthy smoking and nonsmoking subjects, and in schizophrenic smoking and nonsmoking subjects. We hypothesize that physostigmine-induced elevated ACh levels will lead to a reduction in the availability of nicotinic receptors for the binding of the radioligand. We hypothesize there will be greater increase in ACh level (or greater reduction in radio tracer binding) in smoking as compared to nonsmoking subjects. We hypothesize there will be greater increase in ACh level (or greater reduction in radio tracer binding) in smoking as compared to nonsmoking subjects with schizophrenia, but the extent of this change will be different than in controls. We are also measuring the sensitivity of PHNO binding to changes in dopamine levels in healthy smoking and nonsmoking subjects before and after amphetamine challenge.
We propose a prospective multicenter study, whose originality lies in the inclusion of the naive child and adolescent population. Its purpose is to evaluate the incidence of adverse events related to the use of l antipsychotic drugs in children and adolescents with no history of taking such drugs. The inclusion criteria will be: (1) male or female inpatients, (2) aged from 6 to 18 years, (3) requiring antipsychotic treatment, (4) receiving antipsychotic drug for less than 28 days without taking antipsychotic before or with a history of antipsychotic over a maximum period of three consecutive months and discontinued for at least 6 months. Therapeutic monitoring during the 12 month study period will include clinical assessments and laboratory testing. These assessments will be performed before treatment (at inclusion), and at 1, 3, 6, 9, 12 months after the introduction of the antipsychotic drug.
This clinical observational study aims to investigate the efficacy of olanzapine (Villamos ®) in accordance with the instructions attached thereto in standard clinical practice, followed by the physician to the patient. This is a multicenter, non- interventional observational study , 6-month period without preparing the patient to take the usual his medication . A total of 3 scheduled visits : Visit 1 to Day 0 ( integration , base ) , Visit 2 at month 3 and Visit 3 at month 6 ( = end of treatment) . The purpose of the study is to demonstrate the efficacy and safety of olanzapine in patients who are indicated . Will be monitored and recorded all the different concomitant therapy . The treatment of each patient is an individual designated by the physician , according to standard clinical practice and without any intervention research purpose . During the six months of observation patients visit the clinic at the beginning (day 0 ), intermediate ( 3 months ) and end (month 6). The purpose of these visits is regularly monitored by their doctor for senile dementia and their behavior .
A study to compare the change in symptom severity in participants with schizophrenia or related psychotic disorder when treated with GWP42003 or placebo in conjunction with existing anti-psychotic therapy over a period of six weeks.
This is a randomized, double-blind, double-dummy, parallel- controlled, adjustable dose, non-inferiority and multicentre study designed to evaluate the efficacy and safety of lurasidone on schizophrenia for 6 weeks treatment, and to compare with risperidone.
Rationale: There is ample evidence that inflammatory processes play a role in the pathophysiology of schizophrenia. Although Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) have been shown to be able to reduce symptoms in these patients, these drugs either have unfavourable cardiovascular side effects or are otherwise not well tolerated. Moreover, patients with schizophrenia already tend to have an increased cardiovascular risk. The combination of well-established vascular protection and reduction of inflammation by simvastatin offers a highly attractive potential to further improve the treatment of schizophrenia and related disorders. Hypotheses: Daily treatment with 40mg simvastatin in addition to antipsychotic treatment reduces psychotic symptoms, improves cognition, attenuates brain volume loss, and decreases the risk for metabolic syndrome as well as for movement disorders, when compared to placebo. Objective: The primary objective of this trial is to investigate the proposed beneficial effect of simvastatin as compared to placebo when given for one year in addition to antipsychotic medication to patients with psychotic disorder. We expect lower symptom severity as measured with the PANSS (Positive and Negative Syndrome Scale) and less cognitive decline as measured with the BACS (Brief Assessment of Cognition in Schizophrenia).Secondary objectives are assessment of general functioning, presence and severity of metabolic syndrome and degree of movement disorders, and assessments of brain volume. Lastly, we examine various immunological parameters in serum and peripheral blood mononuclear cells and the experience of childhood trauma. Study design: Randomized placebo-controlled double-blind trial. Study population: 150 men and women, between 18 and 50 years of age, diagnosed with schizophrenia, schizoaffective or schizophreniform disorder (DSM-IV 295.*) or psychosis NOS (not otherwise specified) (298.9). Onset of first psychosis no longer than 3 years ago. Intervention: Patients will be randomized 1:1 to either 40 mg simvastatin or placebo daily, in the form of identical tablets.
