What is this Study about?

McMaster University is conducting a study on the effects of brain stimulation in individuals aged 50 and older with dementia or memory loss. The research focuses on using repetitive transcranial magnetic stimulation (rTMS), a noninvasive technique that delivers magnetic pulses to the brain, to enhance cognitive function and balance. The goal is to extend the positive effects of brain stimulation in improving cognition and balance in individuals with dementia.

Compass-ND is a research study designed to assess individuals with different sorts of cognitive and movement changes seen in older adults. We will look at the usefulness of imaging studies, clinical assessments and biomarker tests, together with measurements of memory, thinking and daily functioning, for distinguishing these changes from each other and from healthy aging.

What is this Study about?

This study aims to evaluate how older adults feel about doing a set of tasks that ask them to estimate the duration of various events and ask them to recall past memories or imagine future scenarios. This includes gathering information about the level of difficulty of the tasks and how manageable the duration of the study was. The data from this study will help design a research protocol for future research aimed at evaluating differences in time perception along the continuum of dementia. Findings may be published in a research journal or presented at research conferences.

What is this Study about?

This study explores how adult day programs affect the lives of people living with dementia and their caregivers across several Canadian regions. Over time, we gather information about health, well-being, daily experiences, and quality of life of people living with dementia who attend day program and their caregivers. We also aim to learn about day programs themselves, such as their activities, staffing, challenges, and successes. By combining surveys, interviews, and focus groups, our program of research aims to understand what makes day programs helpful, where challenges exist, and how day program can better support families, and people who use them.

Hearing loss is the third most common chronic health condition among people 65 and older and increases the risk of social isolation, depression, communication difficulties and dementia. Dementia risk may be reduced through hearing rehabilitation, and it is critical to develop tools for identifying hearing loss and its impact on communication. The Hearing and Functioning in Everyday Life Questionnaire (HFEQ) is a measure to identify hearing loss and everyday life functioning, not yet been evaluated for people with combined hearing loss and cognitive impairment. To bridge this gap, the aim is to evaluate the HFEQ for this group. The study has a cross-sectional observational study design. Adults over 60 years, with hearing loss and with and without cognitive impairment will be recruited. Data collection will include a cognitive and hearing assessment, assessment of conversation effectiveness and efficiency, hearing and general health history and five questionnaires (HFEQ, the Life-Space questionnaire, the Social Functioning in Dementia scale, and the PROMIS anxiety and depression scales).

This randomized controlled study evaluates the efficacy of a hippocampus-targeted, computerized spatial memory intervention in older adults with Mild Cognitive Impairment (MCI). Participants (≥55 years) will be randomized to either (a) a spatial memory intervention program or (b) an active placebo. Primary outcomes are changes in memory and cognition from baseline to post-training and 6-month follow-up, assessed with standardized neuropsychological measures and validated spatial memory tasks. Secondary outcomes include everyday functioning, quality of life, perceived stress, and related psychosocial indices.  

A neuroimaging sub-study acquires structural MRI and task-based fMRI to quantify hippocampal morphometry and functional recruitment; we hypothesize training-related improvements will correlate with hippocampal structural/functional change. Exploratory biomarkers (lipids, glucose/insulin for HOMA-IR, cortisol) and polygenic risk scores for dementia are obtained to control inter-individual variability and potential moderators/mediators of training response. The central hypothesis is that sustained, strategy-level engagement of hippocampus-dependent spatial memory will improve cognitive performance in MCI and yield convergent MRI biomarker signatures, supporting experience-dependent plasticity and informing scalable, non-pharmacologic interventions for delaying cognitive decline.

This study will assess if an in-vehicle Driving Monitoring System can identify differences in driving behaviours between older adults who are cognitively healthy, those with mild cognitive impairment, and those with mild dementia. 

What is this Study about?

Many older adults start to experience poorer sleep quality as they age, which can be associated with worse memory and cognition. Previous studies have shown that sleep can be improved when quiet sounds are presented at the right times during slow-wave sleep. We are interested in whether we can improve sleep and associated memory and cognitive function using these sounds in older adults. Information gathered from this study will be used to inform whether quiet sounds presented during slow-wave sleep can improve sleep, memory, and cognitive function.

What is this Study about?

This study aims to evaluate the acceptance and usability of the GuardIO Family Care app, a mobile application designed to support community safety for individuals living with dementia or mild cognitive impairment and their care partners. The study also aims to analyze mobility patterns collected from the app to explore how mobility data can contribute to the early detection of cognitive impairment. The findings will help improve app design, inform care strategies, and support early intervention efforts for individuals living with dementia or MCI.
