Filter by:A randomised phase II double-blinded placebo-controlled trial designed to explore the utility of immunotherapy for patients with acute psychosis associated with anti-neuronal membranes (NMDA-receptor or Voltage Gated Potassium Channel). Primary objective: To test the efficacy of immunotherapy (IVIG and rituximab) for patients with acute psychosis associated with anti-neuronal membranes. Secondary objective: To test safety of immunotherapy (IVIG and rituximab) for patients with acute psychosis associated with anti-neuronal membranes.
The aim of the study is to evaluate the effectiveness of an online intervention through a mobile application, specifically designed for adolescents with a First Psychotic Episode (FEP), as a complement to the pharmacological and therapeutic interventions they receive at their referral center (Treatment as usual). To do this, a longitudinal study will be carried out on patients with FEP and between the ages of 14 and 30, who come to the Child and Adolescent Psychiatry Service of the General Universitarian Hospital "Gregorio Marañón", Psychiatry Department of the Ramon y Cajal Hospital in Madrid and Psychiatry Department of San Joan de Déu in Catalonia. Adolescents and young will be randomly assigned to an experimental group, where they will receive standard treatment plus online intervention, or a control group, where they will receive standard treatment. This online intervention, the continuation of the work of this same team researcher in the "PIENSA program", aims to address little of the more traditional treatments and treatments such as community functioning, quality of life or affective symptoms. In addition, it will increase disease awareness, which will lead to greater adherence to treatment and fewer relapses and rehospitalizations.
The purpose of this trial is to explore parent-child interactions in parents with and without psychosis, and ascertain whether a brief (10 week) supported self-help parenting program offered to parents in their own homes can help improve parents' self-efficacy and general well-being, as well as interpretations of their parent-child relationship and child behaviour in children who are 3-10 years old.
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 this study is to determine if candidate polymorphisms in brain-derived neurotrophic factor (BDNF) and catechol-o-methyl transferase (COMT) are predictive of psychosis disorder severity, symptomology, and resolution in patients at BCPP. A secondary objective will be to form a biorepository of blood and saliva samples from patients at BCPP so that further genetic, proteonomic and pharmacogenomic studies may be done to gain insight into the genetic basis of differences in psychosis disorder presentation and manifestation, and differences in response to antipsychotic drug treatment.
The aim of this project is to undertake a randomized placebo controlled trial of cognitive remediation therapy (CRT) that focuses on working memory training in a sample of community based patients with chronic schizophrenia or other psychoses. Cognitive deficits are a problem for many people with schizophrenia. This study will use computerized cognitive remediation training (which the participant can carry out at home) over a period of a few months.
The purpose of this study is to evaluate an integrative therapeutic concept for schizophrenic patients with comorbid substance use disorder.
In the first year of treatment after a FE of SCZ, 75% to 90% of patients achieve remission from psychotic symptoms. However, approximately 40% of FE patients are non-adherent to medication regimes and more than 60% have intermittent periods of gaps of non-adherence. Relapse rates are high with 82% of patients relapsing at least once within 5 years. Unfortunately even amongst those who do achieve full remission from psychotic symptoms, functional recovery remains a major challenge for patients. All the evidence suggests that individuals with SCZ do best with a combination of pharmacology and psychosocial intervention. Cognitive-behavior therapy (CBT) is gaining recognition as an effective treatment in SCZ and is in fact the only psychosocial treatment in SCZ with proven durability at short term follow-up. Although it is currently being used, the investigators need to learn more about the impact of CBT on FE SCZ especially as experts are advocating for CBT to be a critical component of FE clinical services.
