Filter by:This study aims to test the hypothesis that addition of Individual Placement and Support (IPS) and/or Cognitive Remediation Therapy (CRT) in addition to treatment as usual in patients with early psychosis will be feasible and acceptable in patients with early schizophrenia.
Cognitive remediation (CR) is an evidence-based behavioral skills intervention that targets the cognitive processes underlying functioning in everyday life. It can be used as part of early intervention to reduce cognitive deficits evident at the first episode of psychosis, and has the potential to impact recovery and quality of life. Across Coordinated Specialty Care (CSC) programs, about half of early psychosis participants do not achieve sustained vocational, educational, and/or social recovery; adding CR to CS programs could improve these outcomes. However, models of CR need to be adapted to meet the developmental needs of a younger population and to better fit the CSC model of service delivery. This study of CR implementation will be conducted within the context of OnTrackNY, a network of first-episode psychosis programs that currently offers basic cognitive health evaluation and supportive treatment but not CR. Intervention content will be designed and refined based on input from multiple stakeholders. The study will assess two delivery approaches to CR, one that delivers CR exclusively "in-clinic/clinician-led" and the other that is "partial-remote/independent" with one in-clinic/clinician-led session per week plus out-of-clinic independent cognitive practice. Nine OnTrackNY programs will be selected and OnTrackNY clinicians will be trained to conduct a cognitive assessment battery and CR. Three programs will be randomly assigned to provide treatment as usual (TAU) and six programs will be randomly assigned to provide both TAU and CR (either "in-clinic/clinician-led" or "partial-remote/independent"). Using de-identified data collected routinely by OnTrackNY for quality improvement/program evaluation, the investigators will examine whether the addition of CR improves functional outcomes for clients with first-episode psychosis, compare the effectiveness of CR delivery methods, and explore whether cognitive improvement is associated with improvement in functioning.
Psychomotor slowing is a major problem in psychosis. Aberrant function of the cerebral motor system is linked to psychomotor slowing in patients, particularly resting state hyperactivity in premotor cortices. A previous clinical trial indicated that inhibitory stimulation of the premotor cortex would reduce psychomotor slowing. The current study is further exploring this effect in a randomized, placebo-controlled, double-blind design with three arms of transcranial magnetic stimulation and measures of brain imaging and physiology prior to and after the intervention.
Implementation of 'NAVIGATE' in Ontario aims to help youth and emerging adults suffering from a first episode of psychosis. Although Ontario already has early psychosis intervention programs, the team's recent work has identified major challenges of delivering coordinated care, particularly those elements of care that enhance recovery. These challenges also exist nationally and internationally. By building on the already existing early psychosis intervention community of practice through the Early Psychosis Intervention Ontario Network, the investigators will implement NAVIGATE with the help of CAMH's Provincial System Support Program facilitators. The use of tele-videoconferencing through ECHO Mental Health Ontario and ECHO processes and protocols provide us with an opportunity to ensure sustainability. Using health administrative data held at the Institute for Clinical Evaluative Sciences (ICES), the investigators can examine system-level outcomes, including hospitalizations, emergency department visits, and outpatient physician visits of youth and emerging adults suffering from a first episode psychosis who are treated with NAVIGATE compared with those treated in early psychosis intervention programs without NAVIGATE and those who are not treated in early psychosis intervention programs. In addition, the investigators can also evaluate health care costs. Prior to initiating this project, the investigators obtained the input of youth and emerging adults with a first episode psychosis and family members. The investigators will also continue to measure engagement across the study. Hypotheses: 1. Following the implementation of NAVIGATE, program fidelity (i.e. adaptability) to the Ontario early psychosis intervention standard will improve. 2. Compared to patients not receiving NAVIGATE, those who receive NAVIGATE through this implementation study will have fewer days in hospital, fewer emergency department visits, fewer suicide attempts, lower mortality, and lower healthcare costs. 3. Improvements in functioning and symptoms will be comparable to the RAISE study (an earlier study assessing NAVIGATE); improvement may be influenced by demographic, socio-economic, geographic, and clinical factors. 4. The project's engagement approach will demonstrate that the investigators used the full range of patient engagement based on objectively assessed engagement metrics.
Non-invasive neuromodulation, such as transcranial direct current stimulation ( tDCS) , is emerging as an important therapeutic tool with documented effects on brain circuitry, yet little is understood about h ow it changes cognition. In particular, tDCS may have a critical role to play in generalization, that is how training in one domain generalizes to unlearned or unpracticed domains. This problem has resonance for disorders with cognitive deficits, such as schizophrenia. Understanding how tDCS affects brain circuity is critical to the design and application of effective interventions, especially if the effects are different for healthy vs. psychiatric populations. In previous research, one clue to the mechanism underlying increased learning and generalization with tDCS was provided by neuroimaging data from subjects with schizophrenia undergoing cognitive training where increases in thalamocortical (prefrontal) functional connectivity (FC) predicted greater generalization. The premise of this proposal is that increases in thalamocortical FC are associated with the generalization of cognitive training, and tDCS facilitates these increases. The overarching goals of this proposal are to deploy neuroimaging and cognitive testing to understand how tDCS with cognitive training affect thalamocortical circuitry in individuals with and without psychosis and to examine variability in response within both groups. Study 1 will compare right prefrontal, left prefrontal and sham tDCS during concurrent cognitive training over 12 weeks in 90 healthy controls. Study 2 will be similar in all aspects but will examine 90 patients with schizophrenia or schizoaffective disorder and include clinical assessments. Results of the study will provide crucial information about location of stimulation, length of treatment, modeled dosage, trajectory and durability needed to guide future research and interventions for cognitive impairments.
This study investigates whether visual attention can be improved in individuals with schizophrenia by stimulating the brain via transcranial Direct Current Stimulation (tDCS).
Due to the pandemic, this study was modified from a randomized clinical trial to test the feasibility, initial efficacy, and mechanisms of action of our PTSC-S intervention to a feasibility and acceptability test of our intervention when delivered via telehealth in a single group, within-subjects design.
This application seeks to determine if neurophysiological metrics of memantine (MEM)-enhanced early auditory information processing (EAIP) in schizophrenia (SZ) mediate gains in auditory processing fidelity (APF) and auditory learning.
To evaluate the effects of Estradiol patches vs placebo patches as add-on to antipsychotics on psychometric performance in patients with schizophrenia, schizoaffective or schizophreniform disorder
The investigators propose a cluster randomized effectiveness trial comparing Cognitive Adaptation Training (CAT; a psychosocial treatment using environmental supports such as signs, alarms, pill containers, checklists, technology and the organization of belongings established in a person's home or work environment to bypass the cognitive and motivational difficulties associated with schizophrenia ) to existing community treatment (CT) for individuals with schizophrenia in 8 community mental health centers across multiple states including 400 participants. Mechanisms of action will be examined. Participants will be assessed at baseline and 6 and 12 months on measures of functional and community outcome, medication adherence, symptoms, habit formation and automaticity, cognition and motivation.
