Filter by:This study compares the efficacy and effectiveness of two of the second-generation antipsychotics (SGAs) most used in our society in the treatment of schizophrenia (Aripiprazole and Risperidone) and the investigators do within an assistance program of early-stage psychosis individuals of the Community of Cantabria, clinical reference for the treatment of this disease in the Spanish Autonomous Community. Patients are included in a prospective naturalistic study, open flexible-doses and randomized into one of two possible patterns of treatment that includes the protocol.
The purpose of this study is to determine whether cognitive training exercises can improve cognitive functioning in young patients with recent-onset psychosis who are being treated in community mental health settings using the NAVIGATE model. The investigators will examine the effects of web-based cognitive training exercises delivered on iPads. Participants will be randomized to one of three conditions, and will be assessed at Baseline, Post-Intervention, and 6 Month Follow Up on measures of clinical, neurocognitive, and functional status.
Cannabis use during adolescence represents a significant risk factor for the development of psychosis including schizophrenia. Moreover, cannabis is the most commonly used drug among patients with an existing psychotic disorder. An estimated 25% of patients with psychosis reportedly meet the criteria of a cannabis use disorder particularly among younger patients experiencing their first episode. Cannabis use significantly exacerbates symptomatology resulting in an increased duration of the first hospitalization visit, number of hospital readmissions, and overall reduced functional outcome. Discovering novel strategies to treat the underlying pathophysiology of cannabis dependence early in the disorder may translate into improved functional outcome. Working memory deficits have been shown to predict relapse in the first-year of psychosis and is modulated with cannabis use. Repetitive transcranial magnetic stimulation (rTMS) targeted to the dorsolateral prefrontal cortex (DLPFC) has shown tremendous promise for the treatment of both tobacco dependence and working memory impairment in patients with psychosis possibly through the modulation of gamma (30-50 Hz) oscillations. The proposed study will therefore evaluate the effect of rTMS on abstinence, working memory performance, and gamma oscillations through a randomized, double-blind, placebo-controlled 28-day longitudinal abstinence study design in patients with early psychosis. It will further explore if baseline performance and gamma oscillations predict abstinence in response to rTMS. It is hypothesized that active compared to sham rTMS will improve abstinence rates and improve working memory performance through the modulation of gamma oscillations.
The proposed study aims to use a form of neuromodulation, known as transcranial alternating current stimulation (tACS), to improve the effectiveness of the metacognitive training (MCT) program for treatment of delusions in schizophrenia. tACS is a non-invasive brain stimulation method utilizing weak electrical currents applied to the head to influence neural firing (Antal & Paulus, 2013). Brain regions implicated in delusional thinking will be targeted in the hopes of promoting thinking patterns that will allow participants to question delusional beliefs, reducing the severity of delusions and increasing the positive effects of MCT (Whitman et al., in press; Whitman, Minz & Woodward, 2013). Electroencephalogram (EEG) and behavioural assessments will be used to measure treatment effects. However, before tACS will be administered to individuals experiencing delusions associated with schizophrenia we will conduct various control-phase (pilot) studies to gain a better understanding on how tACS temporarily alters performance on cognitive processes by biasing dominant patterns of oscillations. The objective of the pilot studies is to establish the effectiveness of the EGI GTEN system in modulating brain oscillations in the cortex of healthy participants by means of transcranial alternating current stimulation (tACS). In this control/pilot phase of our study, we aim to establish that we can induce changes in the power of a specific frequency band in targeted cortical regions with neuromodulation using the GTEN system, and we will assess whether doing so temporarily alters performance on simple cognitive and perceptual processes in healthy controls. This will be the first step towards translating our stimulation protocol to the patient population for our primary study of interest (tACS as an adjunct to metacognitive training for delusions in psychosis).
Motivation deficits are a strong determinant of poor functional outcomes in people with schizophrenia. Mobile interventions are a promising approach to improving these deficits, as they can provide frequent cues and reinforcements that support goal-directed behavior. The primary aims of this study are to conduct a pilot study using a randomized design to 1) Test the feasibility and acceptability of a personalized mobile text message intervention, Mobile Enhancement of Motivation in Schizophrenia (MEMS) and to 2) Test the preliminary effectiveness of MEMS compared to a control condition.
The purpose of this study is to perform longitudinal high-resolution 7T MRI and Prisma 3T MRI in participants with first-episode psychosis (FEP) enrolled in our ongoing randomized controlled clinical trial (RCT) of cognitive training. The investigators seek to determine whether a 12-week course of intensive cognitive training of auditory processing in young FEP patients delivered remotely as a stand-alone treatment is neuroprotective against neural tissue loss in auditory cortex (superior temporal gyrus, STG), and possibly in other cortical regions. The investigators will also observe the effects of training on white matter integrity in the brain.
A ten-week study to assess MP-101 in Dementia-Related Psychosis and/or Agitation and Aggression
Cognitive impairments in schizophrenia are the most debilitating aspect of the illness and poorly treated by current medications. This study investigates transcranial direct current stimulation (tDCS) - a safe, noninvasive weak electrical current delivery to stimulate brain function - as a novel therapeutic for cognition in schizophrenia. Integrating neurostimulation, electrophysiology and neuroimaging, this project aims to study tDCS effects on cognition by verifying therapeutic target engagement, evaluating the tolerability of tDCS sessions, and optimizing treatment parameters.
This study will be a randomized controlled trial that investigates the effectiveness of digital picture frames (DPF) installed in inpatient rooms on long stay inpatient wards servicing schizophrenia clients at CAMH. The effects on client experience will consider the domains of self-concept, interactions with healthcare staff, perception of space, and implications for the recovery process. The comparison of inpatient client experience with DPFs versus a control group (Treatment as Usual - TAU), offers the opportunity to examine the effectiveness of this type of environmental adaptation. This trial builds upon earlier work that demonstrated the feasibility of DPFs in this context.
The investigators propose to examine the effectiveness of a brief intervention that might better facilitate the transition into the community for people with schizophrenia or bipolar disorder with psychotic features. The intervention is called the Welcome Basket. It involves Peer Support Workers connecting with and supporting hospitalized individuals in the days before discharge and again in the community in the first month immediately following discharge. The investigators will compare the outcomes of discharge from hospital as usual with the full version of the welcome basket and a preliminary test of an abbreviated 2 visit version of the intervention.
