    What is this Study about?

    Our study titled "Investigating the Role of Quantitative Susceptibility Mapping and Oxygen Extraction Fraction as Advanced Neuroimaging Biomarkers in Alzheimer's Disease" aims to develop non-invasive diagnostic biomarkers for Alzheimer's Disease (AD). We focus on evaluating the potential of QSM and OEF to differentiate between AD, Mild Cognitive Impairment (MCI), and Cognitively Unimpaired populations and to predict amyloid and tau pathology, using a Systems Biology approach. Leveraging the McGill University's TRIAD cohort, the study utilizes advanced imaging and machine learning to predict amyloid and tau presence, which could transform AD diagnostics and treatment. Methodologically, it involves preprocessing neuroimaging data and employing machine learning classifiers to analyze these features. The anticipated outcomes include validating QSM and OEF as non-invasive biomarkers for AD, establishing their correlation with amyloid and tau proteins, and developing predictive models for clinical decision-making, potentially resulting in significant advancements in AD diagnostics.

    Eligibility Criteria

    Are a member of the TRIAD cohort at McGill University, falling within one of the following categories: young control, cognitively unimpaired, mild cognitive impairment, or Alzheimer's Disease.

    Are willing and able to undergo advanced neuroimaging techniques including MRI and PET without contraindications.

    Have not had any significant neurological conditions (other than AD for the AD group) that might interfere with the results of the study.

    Have no metal implants, devices, or other conditions that may contraindicate or distort MRI imaging.

    Are not currently participating in other clinical trials or studies that involve interventions which might interfere with the results of this study.

    Are able and willing to provide informed consent for participation in the study or have a legally authorized representative who can do so.

    Do not have a history of substance abuse or other conditions that might confound the imaging and cognitive data.

    Have not undergone any significant head trauma or surgery in the past 6 months.

    Are not pregnant or planning to become pregnant during the duration of the study.

    Are willing to comply with all study-related procedures, imaging sessions, and follow-up evaluations.

    Ability to speak English and French

    What is this Study about?

    The purpose of this study is to assess whether a virtually-delivered healthy lifestyle intervention (over Zoom) is feasible for individuals who feel that their memory or thinking is declining.

    Eligibility Criteria

    -Are between the age of 65-85

    -Are concerned about your memory and other thinking abilities

    -Have access to internet at home

    -Are a resident of Saskatchewan, Manitoba, Ontario, or Quebec

    What is this Study about?

    The aim of our study is to better understand whether certain lifestyle factors (such as physical activity and hearing) are related to early changes in memory and thinking abilities in older adults. We are especially interested in enrolling individuals who are South Asian or East Asian, because little research has focused on brain health in Canadians of diverse racial/ethnic backgrounds.

    By participating, you will help us better understand how lifestyle factors are related to memory and thinking changes in adults from diverse communities. We hope that this will lead to improved prevention and early intervention strategies for dementia.

    Eligibility Criteria

    You are eligible to participate if you…

    - Are 55-85 years old

    - Have no major medical or psychiatric diagnoses

    - Are comfortable speaking and reading English

    - Are able to undergo an MRI scan

    -Speak English

    Eligibility is dependent on an additional conversation with the study team.

    The study is aiming to assess whether nutritional intervention with personalized, preselected prebiotics can affect cognitive function in those with Alzheimer’s disease. This study is placebo-controlled, and participants will be randomized to either the placebo or prebiotic.

    Eligibility Criteria

    • Aged 60 or older
    • Diagnosis of Mild Cognitive Impairment, Alzheimer’s disease, or Amnestic Mild Cognitive Impairment
    • Has someone who can be their study partner

    What is this Study about?

    We want to determine if a nutrition questionnaire (SCREEN) works well to identify nutrition challenges for older adults with diagnosed memory problems, cognitive impairment or dementia when completed by themselves, or by a care partner on behalf of their cared for person.

    Eligibility Criteria

    You may be eligible if you are:

    • 55 years or older

    • Read/speak English

    • Live within 45km of Waterloo, Guelph or London.

    AND are an:

    • Older adult with diagnosed memory problems, cognitive impairment or dementia with a care partner who either lives with you, or who is in daily contact with you and would be able to support reporting of their eating behaviours

    • If living in a retirement home, the older adult must have lived in their home for at least 3 months and receive 2 or more meals each day from their retirement home

    Caregivers of people living with dementia have direct experience of how the dementia is progressing. They are essential in evaluating the real-world benefits of treatment and making decisions to keep the person at home or consider different levels of care. The aim of this study is to develop a new CAregiver REported and weighted Dementia outcome measure (CARED).

    Eligibility Criteria

    • Caregiver to a person living with dementia
    • You provide assistance with activities of daily living
