    Identifying Early Cognitive Decline Across the Dementia Continuum Using a Remote Digital Screener

    What is this Study about?

    This study evaluates an at-home, digital cognitive screening tool for older adults experiencing memory changes across the dementia continuum. Participants will complete a brief series of engaging, online brain games and surveys to determine the tool's accuracy compared to traditional clinical assessments. The goal of this study is to provide accessible, patient-friendly monitoring of brain health that reduces the need for clinic travel and lowers barriers to early detection of dementia.

    Eligibility Criteria

    You are eligible to participate if you:

    Are 50 years of age or older

    Either have healthy cognition or are experiencing noticeable memory or thinking changes (Subjective Cognitive Decline), or have a clinical diagnosis of Mild Cognitive Impairment (MCI) or dementia.

    Have access to a computer, laptop, or tablet with a reliable internet connection.

    Are able to provide informed consent, or have a legally authorized Substitute Decision Maker (SDM) who can provide consent on your behalf.

    Have adequate vision and motor skills to view a screen and tap or click to respond to prompts (such as a choice reaction time task), using glasses or standard aids if necessary.

    Are able to read and communicate in English.

    Do not have comorbid psychiatric conditions that interfere with cognitive function Do not have a history of brain injury or neurodevelopmental disorders

    Examining Social Support among Black Dementia Caregivers in the Greater Toronto Area

    What is this Study about?

    This study examines how Black family caregivers in the Greater Toronto Area experience and access social support while caring for a relative living with dementia. Using Straussian Grounded Theory informed by Critical Theory and Intersectionality, the research explores how factors such as race, culture, gender, and community shape caregiving experiences and support-seeking behaviours. Findings will be used to develop theory grounded in the lived experiences of Black caregivers, and to inform more culturally responsive dementia care policies, services, and supports across Canada. This study has been approved by the York University Research Ethics Board (Protocol 130, April 2026).

    Eligibility Criteria

    You are eligible to participate if you:

    • self-identify as Black (for example, African, Caribbean, Black Canadian, Afro-Latin, or another Black identity)
    • are 18 years of age or older
    • live in the Greater Toronto Area
    • provide unpaid care to a family member living with dementia
    • can speak and understand English well enough to take part in an interview

    Levetiracetam for Persons at Risk for Alzheimer's Disease (ALEVIATE-2)

    What is this Study about?

    The goal of this study is to investigate whether very small doses of a drug called levetiracetam (LEV) may reduce abnormal brain signaling in the brain in individuals who are at an increased risk for developing Alzheimer's Disease. Only participants who show the abnormal brain signaling on a functional MRI (fMRI) scan of the brain will be enrolled in the study. Enrolled participants will receive 4 weeks of treatment with LEV and 4 weeks of treatment with placebo (a sugar pill). The study involves cognitive testing, genetic testing, bloodwork, ECGs, questionnaires and several brain imaging scans.

    Eligibility Criteria

    • Are between 55-85 years of age

    • Have a parent or sibling with Alzheimer’s disease or with dementia that may be due to Alzheimer’s disease (even if not diagnosed as such)

    • Feel your memory is getting worse

    • Get normal scores on tests of thinking and memory (will be done as part of the study)

    • Are able to undergo brain MRI scans

    • Have a study partner (friend or family member) willing to answer questionnaires about you

    • Show increased brain signaling during the screening fMRI scan (Note: We anticipate that most people who sign up for the study will NOT show the increased brain activity levels required to qualify for the study treatment)

    Nature-based Virtual Reality Intervention for Depression in Alzheimer’s Disease (VRN-AD)

    What is this Study about?

    This study looks at how an at-home nature-based virtual reality (VR) program may help people living with Alzheimer’s Disease manage behavioural and psychological symptoms of dementia (BPSD), such as depression. Caregivers and/or study partners will have the option of taking part in the study and providing feedback regarding the VR intervention. This project will explore how virtual reality can be used as a non-pharmacological approach to prolong aging in place for individuals with BPSD, as BPSD contributes to rates of institutionalization.

    Eligibility Criteria

    • Are 50 years or older
    • Have been diagnosed with mild to early-moderate Alzheimer's disease (including mixed dementia)
    • Are medically stable and able to take part safely
    • Experience mild to moderate depressive symptoms
    • Feel comfortable using basic technology, such as a tablet or headset
    • Have access to Wi-Fi and a smart device (such as a phone or tablet) for online sessions and study apps
    • Have someone available to be present during all study sessions

    A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of ML-007C-MA for the Treatment of Hallucinations and Delusions Associated with Alzheimer's Disease Psychosis

    What is this Study about?

    ML-007C-MA-221 is a Phase 2, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of ML-007C-MA in male and female participants aged 55 to 90 years with hallucinations and delusions associated with Alzheimer's Disease Psychosis (ADP).

    The primary objective is to evaluate the efficacy of ML-007C-MA compared with placebo for the treatment of hallucinations and delusions associated with ADP as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.

    Eligibility Criteria

    Male or female participants aged 55 to 90 years of age
    Must have a study partner
    Presence of psychotic symptoms for at least 2 months before Screening.
