Filter by:Verbal episodic memory is an independent declarative memory system associated with language and is responsible for storage and conscious recall of previous personal experiences. Verbal episodic memory is impaired in schizophrenia and is related to patients' functional outcomes. Because no medication has shown clear positive effects on verbal memory impairment in schizophrenia, there is a great need to find effective cognitive remediation treatments (CRT) that could improve this domain in this psychiatric population. Although CRT programs have shown small to moderate positive effects on verbal memory in individuals with schizophrenia, traditional lab-based computerised cognitive interventions have notable attrition rates. In recent years, along with the advancement of technology, the development of Virtual Reality (VR) has allowed the possibility for new training techniques. Previous studies have established the initial feasibility and safety of using VR in schizophrenia population. However, no studies have examined the feasibility, safety and efficacy of combining VR technology with verbal memory training among individuals with schizophrenia. Thus, in this study, we will adapt an exercise from the Strategy for Semantic Association Memory (SESAME; (Guimond et al., 2018; Guimond & Lepage, 2016) training to a VR environment. We aim to determine the feasibility of using virtual reality in the context of a cognitive remediation intervention and to assess the initial efficacy of our verbal memory training on the use of semantic encoding strategies in people with schizophrenia. We also aim to assess participants' experience and tolerability of the VR training.
Substantial data support early interventions for people experiencing First Episode Psychosis (FEP) to ameliorate symptoms and minimize disability. FEP programs have been widely and successfully implemented in high-income countries. With the partial exception of Chile, however, there is not a single low-and-middle-income country (LMIC) that offers universal access to FEP services. Chile is unique among LMICs in having created a platform for the implementation of FEP services, including 1) an FEP policy that mandates identification of FEP individuals at primary care and delivery of community-based FEP treatments at outpatient mental health clinics, and 2) a public health care system within which this mandate can be fulfilled. Nonetheless, previous research has documented that FEP services provided at mental health clinics do not conform to recently established evidence-based approaches. Therefore, the overarching goal of this proposal is to address the shortfall in evidence-based practices for FEP in Chile by first adapting OnTrackChile (OTCH) from OnTrackNY (OTNY), a coordinated specialty care program for FEP currently being implemented across the US, and then implementing OTCH on a wide scale. Like most FEP programs, OTNY is clinically effective, but unlike most others, it also has a well-established training and technical assistance infrastructure, and a proven track record of being scaled up in large urban areas. To achieve this goal, the Dynamic Adaptation Process will be used to first inform the adaptation and implementation of OTCH in the Chilean context. Then, a Hybrid Trial design will be employed to evaluate the implementation of OTCH as well as its effectiveness and cost in a cluster-randomized controlled trial (RCT) (N = 300 from 21 outpatient clinics). The OnTrackChile program will be offered in half of these outpatient clinics; usual care services will continue to be offered at the other clinics. Study participants (ages 15 to 35) attending an outpatient clinic assigned to the intervention arm will receive the OTCH coordinated services provided by an interdisciplinary team, based on the interests, needs, and preferences of each study participant. Study participants attending outpatient clinics assigned to "usual care" will receive the usual services offered to people with a wide range of mental health conditions, not just those experiencing first-episode psychosis. The study will engage participants over the course of two years, with interviews to evaluate their experiences at the beginning of their participation, and again after 12 months and 24 months. Over the course of the study, 4-5 mental health providers will also be interviewed at each of the participating clinics (up to 105 additional interviews at the three timepoints). The data collected in this study will help researchers evaluate the effectiveness and cost of FEP treatments based in outpatient clinics and factors which may help or hinder these outcomes.
Persons affected by psychosis have a shorter life expectancy mainly due to metabolic disorders. This is partly due to the drugs but also to a sedentary life style. It is often a life long disorder with decreased overall function and thus need of life long care, both informal and formal. It is also a highly stigmatising disorder. We are aiming at adding peer mentor led regular physical exercise to the open care of psychosis. it is well-known that physical exercise increase overall function, decrease metabolic risk factors and increase cognition. By using educated peer mentors who will lead the exercise sessions this will have an anti-stigmatising effect and improve self-confidence.
Source-monitoring is a cognitive process that refers to the ability to remember the source of an information. Some studies have showed source-monitoring deficits in patients with schizophrenia as well as in individuals at ultra-high risk for psychosis (UHR) and in first-episode psychosis patients (FEP). Source-monitoring deficits have thus been proposed as a potential early risk factor for psychosis. However, further studies are needed to better characterize this deficit. The aim of this project is to investigate source-monitoring performances in UHR, FEP patients and healthy controls (HC) and to characterize these deficits in terms of brain anatomy, basic auditory processes and social functioning.
The purpose of this study is to determine if taking a synbiotic supplement versus a placebo will reduce symptoms of schizophrenia when used in addition to standard antipsychotic medications.
To explore the whole-brain anatomical and functional abnormalities in drug-naive patients with schizophrenia ,drug-naive patients with BD, drug-naive patients with MDD and healthy controls by using a combination of cross-sectional and longitudinal study designs, including a longitudinal study with 8 weeks of drugs treatment. And explore whether there are shared imaging biomarkers between these three common mental disorders.
The purpose of this study is to address the shortcoming in clinical hallucination research by causally manipulating the neural loci of conditioned hallucination task behavior in-person in patients with psychosis using transcranial magnetic stimulation (TMS), tracking the impact of this manipulation on the number of times participants with hallucinations report hearing tones that were not presented. With such a causal intervention, the veracity of this explanation of hallucinations will be either validated or disconfirmed. If validated, the task can be further developed as a biomarker for predicting the hallucination onset, guiding, developing or tracking the effects of treatments for hallucinations.
This 12-month study will evaluate the efficacy of aripiprazole lauroxil compared to oral aripiprazole in preventing the re-emergence of psychotic symptoms in patients with a recent onset of schizophrenia.
The purpose of this study is to assess professional quality of life in German nurses working with patients with mental disorders.
The purpose of this study is to examine the physical activity recommendation behaviour, beliefs, barriers and exercise participation in German nurses working with patients with mental disorders.
