Filter by:This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial of curcumin for the treatment of cognitive impairment in schizophrenia.The primary aim of this pilot trial is to provide an effect size estimate for the efficacy of curcumin in improving cognitive functioning in schizophrenia. Secondary goals are to determine the effect of curcumin over time on negative and positive symptoms, in association with inflammatory markers.
This project is a component of a broader research program referred to as "Self-Management and Recovery Technology (SMART): Use of online technology to promote self-management and recovery in people with psychosis", which has been funded by the Victorian Department of Health Mental Illness Research Fund (MIRF33). The overall research program is examining the therapeutic potential of using online (Internet-based) educational and multimedia resources in mental health services. It involves the development of a website which can be accessed via an internet browser on a desktop computer, tablet computer, or smartphone. It consists of a series of educational modules containing textual information, exercises, audio, and video clips designed to promote self-management and recovery in people with a history of persisting mental illness. This particular project (SMART-Therapy) involves a randomised controlled trial examining the use of a discrete 8-session psychosocial intervention delivered in addition to routine care which utilises these online materials. The intervention will involve a mental health worker meeting with the participant with a tablet computer (e.g. iPad) on which online materials can be viewed, and used to guide an interaction with the participant. The randomised controlled trial will include 148 participants, who will be randomised to receive one of two interventions: (a) meeting with a support worker using the SMART website to guide interaction (health intervention), or (b) meeting with a support worker delivering a social interaction-based control condition (social intervention). In each condition, there will be 8 x 50min face-to-face sessions over 3 months. Assessments will be completed pre-randomisation, and at 3, 6 and 9 months. The primary hypothesis is that participants randomised to the health intervention will show greater improvement in personal recovery than participants randomised to the social intervention, and that these improvements will be maintained at follow-up (6 and 9 months following intake).
The purpose of this study is to determine the number of Medication Treatment Modifications (MTMs) made by the clinician at every visit when antipsychotic medication plasma levels (AMPL) results are available compared to when AMPL results are not available.
The purpose of this study is to test the feasibility of a modification of CET (Cognitive Enhancement Therapy) to address symptomatic and functional difficulties associated with Clinical High Risk for Psychosis (CHR). Cognition for Learning and for Understanding Everyday Social Situations (CLUES) is designed to improve cognitive functioning (e.g., memory, attention, planning, etc.) in order to improve school, work, and social functioning. CLUES includes the following: 1. Computerized cognitive remediation ("exercises") to improve cognition. 2. Social-cognitive skills group designed to teach participants to act wisely in social situations. 3. Individual coaching sessions designed to enhance translation of skills learned from computer exercises and the group into real life. CLUES is based on Hogarty and Greenwald's Cognitive Enhancement Therapy (CET), which was designed for treating individuals with schizophrenia. Research on CET for individuals with schizophrenia has found that CET appears to have helped participants improve cognition and social and work functioning. This study will investigate the feasibility of CLUES for young people who are showing signs of clinical risk for psychosis. Part 1: Preliminary open label trial of CLUES (n=8) to examine preliminary evidence of target engagement (change in cognition and social cognition), to refine assessment and recruitment approaches, to further optimize the treatment manual, and to ascertain feasibility and tolerability. Part 2: Preliminary randomized controlled trial of CLUES vs supportive therapy (ST) + computer games to explore preliminary evidence of efficacy of CLUES vs. the control treatment (n=30).
The investigators programme of research will evaluate an existing physical health care screening intervention with the aim of helping Community Psychiatric Nurses (CPN) to improve the physical health wellbeing of people with a SMI. This pilot clustered randomised controlled trial aims to establish the potential efficacy and acceptability of the Chinese Health Improvement Profile (CHIP) in improving the physical health of people with severe mental illness.
Psychosis is a mental health problem that causes people to perceive or interpret things differently from those around them, often involving hallucinations or delusions. Psychosis and schizophrenia are common disorders which predominantly affect younger adults. Recently, the investigators discovered that 5-10% of people with psychosis have antibodies in the blood that are capable of targeting the surface of brain cells, specific to the N-methyl-D-aspartate (NMDA) receptor or voltage gated potassium channel complex, which the investigators believe may be causing the problem. Those positive for antibodies may have a problem with their immune system and this may prevent their brain from working normally. This trial aims to test the feasibility of removing or reducing the antibodies in patients' blood, using immunotherapy, and see if this improves symptoms of psychosis. Immunotherapy in this feasibility study will involve giving all patients steroid tablets and half of them will also receive a drug called "intravenous immunoglobulin" whereas the other half will have a procedure called "plasma exchange". The feasibility study is designed to identify which method of immunotherapy is most suitable for use in this patient population. Results from this will inform on the methodology used for a proposed larger randomised control trial.
Background Paliperidone is an active metabolite of risperidone, both of which are antipsychotic agents for treatment of schizophrenia and related psychotic disorders. Pharmacogenetic studies have revealed that the efficacy and side effects of antipsychotic agents are related to polymorphisms of specific genes, however, there are just a few related studies on paliperidone. The current study aims to evaluate whether pharmacogenetic markers related to risperidone and genetic markers associated with schizophrenia have effects on the clinical effectiveness of paliperidone treatment. The study also uses changes of event-related potentials (ERP) as indices for clinical efficacy. Methods It is a prospective, open-label, non-randomized and uncontrolled clinical trial to study the efficacy and side effects of 6-week paliperidone ER treatment for patients with schizophrenia or schizoaffective disorder. The first three weeks of treatment has to be inpatient treatment. In the first two weeks, participants will take 9 mg paliperidone ER daily. Then the dose of paliperidone can be adjusted to within the range of 6-12 mg per day. Efficacy indicators include symptom severity, global functioning, and ERP. Side effect indicators include common side effect evaluate, extrapyramidal symptoms, metabolic profiles, hormonal change, and bone metabolism indices. Participants will also receive examinations for blood drug concentration, genetic polymorphisms, and epigenetic markers.
The perception of music requires coordinated neural activities in distributed multi-functional centers across both hemispheres. The association between musical abilities and other general cognitive functions have been studied in several populations with inconsistent results. Schizophrenia is a major mental disorder that is strongly associated with cognitive deficits. These often appear before the onset of psychotic symptoms and persist throughout effective treatment of positive and negative symptoms. Like other disorders of psychosis, schizophrenia features general deficits in auditory memory and sensory processing. Recently, Sawada et al. (2014) and Wen et al. (2014) studied music abilities in Japanese and Chinese schizophrenic populations. They both used a standardized assessment for amusia called Montreal Battery of Evaluation of Amusia (MBEA) and found marked impairments in perception of scale, contour, interval, rhythm, meter and memory. Both studies showed that deficits in music perception were associated with cognitive deficits and negative symptoms. In regards to positive symptoms, Wen et al., but not Sawada et al., found a significant association. The present clinical study will assess musical abilities using the MBEA in a Canadian population with and without refractory psychosis. It will explore associations between musical deficits, positive and negative psychiatric symptomology and cognition. The patient population will have a diagnosis of schizophrenia, schizoaffective disorder, affective disorder with psychosis or non substance-related psychosis who were referred to the British Columbia Psychosis Program (BCPP) due to inadequate or no response to at least two trials of antipsychotics. A focus on refractory psychosis may provide greater insights because these patients have relatively more pronounced psychiatric symptoms and cognitive deficits. It will also be valuable to administer the MBEA assessment on a Canadian population, because the test was originally intended for Western populations and its musical phrases were designed with Western tonalities.
The purpose of the study is to compare effectiveness of paliperidone palmitate (PP: paliperidone palmitate once-monthly and 3-month injections) versus oral antipsychotic (OAP [that is oral paliperidone extended release {ER}, oral risperidone, or another OAP]) in delaying time to treatment failure. The study will also evaluate changes in cognition, functioning, brain intracortical myelin (ICM) volume following treatment with PP compared with OAP in participants with recent-onset schizophrenia or schizophreniform disorder.
The proposed study will involve a randomized trial of Cognitive Adaptation Training (CAT) for early intervention as compared against an active control in which Action Based Cognitive Remediation (ABCR) will be applied.
