Filter by:This one arm clinical study will assess the impact of a goal directed therapy intervention, aiming at optimizing depth of anesthesia and intraoperative blood pressure on the incidence of postoperative cognitive dysfunction and delirium relative to a standardized anesthetic plan. We will enroll 60 patients and will measure the neurocognitive status (MoCA test) of patients before and after surgery (at discharge, within 2 weeks after surgery and 6 months after surgery) to determine the relative impact of anesthetic care on the development of postoperative delirium and cognitive decline. All patients will have a brain scan (fMRI) before and after surgical intervention. Patients will also be asked to participate in an optional blood draw which will take place during their brain imaging visit and post operatively (within 2 days after surgery).
The primary objective of this project is to assess the feasibility of multi-field, extended HD-tDCS (MFE-HD-tDCS) with simultaneous computerized CT as a viable intervention to improve cognitive function in patients with MCI. This double-blinded, randomized pilot clinical trial of repetitive daily HD-tDCS/sham HD-tDCS, administered in combination with CT to subjects with MCI in 3 monthly blocks of 5 daily sessions for a total of 15 sessions will enroll 8 participants.
The investigators conducted a prospective observational pilot study to explore the incidence of peri-operative covert strokes (detected by brain MRI) and the potential impact on delirium and cognitive decline in post-operative cardiac surgery patients at the Hamilton General Hospital. This pilot study assessed the feasibility of a larger prospective international cohort study exploring this objective.
The specific aims of this study are: Aim 1. Develop a staged and modifiable dyadic oral care intervention to provide functionally-tailored oral care rehabilitation for community-dwelling persons with dementia (PWD) and need-based skills training their family caregivers (CGs). Based on the literature review and MCWB, a 4-week intervention with 8 modules, including universal modules (e.g., environmental changes), CG modules (e.g., cuing strategies) and modules for both PWD and CGs (e.g., oral care techniques), will be developed addressing the relevant SCT constructs (e.g., functional deficits of PWD and caregiving needs of CGs). Guided by a validated, widely-used theory of rehabilitation medicine, modules will be used alone or in combination to provide personalized, hand-on, functionally-tailored oral care rehabilitation for PWD along with skills training for CGs to match their caregiving needs. The training focus shifts from the PWD to the CG, as the independence of the PWD decreases. Semi-structured interviews with family CGs will then be conducted (until data saturation is reached) to understand their oral care needs, desired intervention approaches, and the perceived feasibility and utility of the intervention. The intervention will be revised and then pilot tested with 4 dyads, one per each of the four functional levels of the DAT. Aim 2. Evaluate the feasibility and efficacy of the intervention in home settings through a randomized, controlled trial with 40 pairs of PWD and their primary CGs, including immediate post-intervention and 3-month follow-up. Dyads will be stratified into 4 functional levels based on the PWD's DAT score and then randomly assigned to the intervention or control (non-tailored usual care) group.
Multimodal training, including physical and cognitive activities, has been associated with a reduction in age-related physical and cognitive decline. Therefore, combining these activities into a home-based computerized training program may represent a powerful approach to foster independent life at home. The StayFitLonger study is a 6-month multi-site randomized controlled, double-blind trial, which tests the efficacy of a home-based computerized intervention that combines physical and cognitive exercises through virtual coaching to enhance motivation. In Switzerland, Canada and Belgium, a total of 128 older participants will be recruited and randomly assigned to one of two physical and cognitive home-based interventions for 6 months: StayFitLonger or active control training. The StayFitLonger intervention provides physical and cognitive training exercises, feedback and instructions through a virtual coach to optimize motivation. It also offers social and psycho-educational contents. Monthly supervision (home-visits and phone calls) will be provided during this 6-month intervention. Outcomes will be measured at baseline, and after 6 months of training. This study will demonstrate the feasibility, sustainability and efficacy of a home-based multi-domain intervention program allowing further development and possible commercialization of a scientifically validated training program to slow down cognitive and physical decline.
The aim of this study is to assess the use of ASPECTS and stroke biomarkers to predict the outcome and cognitive impairment in acute ischemic stroke.
Cancer-related cognitive dysfunction (CRCD) affects up to 75% of patients receiving chemotherapy and older adults are at greater risk of developing CRCD, which can negatively affect their functional independence and quality of life. Memory and Attention Adaptation Training (MAAT) is a promising treatment for CRCD that improves perceived cognition in younger cancer survivors, but needs to be adapted for older adults to address their unique needs. The proposed study will adapt MAAT for older adults using feedback from key stakeholders (older adults with cancer and their caregivers), and test usability of the intervention.
The investigators propose to apply neuroplasticity-based computerized cognitive remediation (nCCR) to treat chemotherapy-related cognitive impairment (CRCI).
The study was a prospective cohort study to assess the effect of age, duration of anesthesia, repeated surgery, and type of surgery on cognitive impairment in 108 geriatric patients (≥60 years) who underwent general anesthesia for non-neurologic noncardiac surgery.
Acute post-operatory cognitive dysfunction states are one of the most important complications in older patients after surgery. Two acute cognitive dysfunctions have been described: postoperative delirium (PD) and postoperative subsyndromal delirium (PSSD). Patients who develop delirium, both as a complete or incomplete syndrome, have poor long-term outcomes, such as longer length of hospital stay, institutionalization at discharge, and even higher mortality, and consequently, the human and economic costs significantly increase for the health system. Here the research team will use an observational cohort, investigator blinded in two-center with a primary endpoint to validate the relative alpha power ratio as a predictive biomarker of postoperative cognitive dysfunctions.
