Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Rationale. The Canadian population is aging. According to recent estimates, the proportion of the population aged 65 and older will increase rapidly from 13% in 2005 to 25% by 2031. This increase in proportion is accompanied by a considerable amount of disability and subsequent dependency which has major effects on both the quality of life of older adults and their caregivers, and on the Canadian health care system. An important goal of geriatric medicine is to reduce the gap between life expectancy and disability-free life expectancy by reducing disability and dependency in the later years of life. A substantial portion of this disability stems from two major geriatric syndromes: cognitive impairment and mobility limitation. The ultimate manifestations of these syndromes are dementia and falls. Interestingly, these manifestations often coexist in elderly people: falling is a common geriatric syndrome affecting about a third of older adults each year, and dementia affects about a third of Canadians aged 80 and over. Together, dementia and falls are responsible for much of the discomfort, disability, and health care utilization in older adults and each will become more prevalent as older Canadians are expected to number approximately $9 million by 2031. The combined direct cost of dementia and falls for the Canadian Health System is over $4.9 billion per year.
Establishing reliable and easy to obtain predictors to accurately identify MCI patients at highest risk of progressing to dementia is essential first, to determine who will benefit from additional and/or invasive testing and second, to implement preventative strategies, including cognitive training, physical exercises, and aggressive vascular risk factors correction to delay progression. Even a modest one-year delay in dementia incidence could save Canada $109 billion over 30 years.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Blood test for genotyping (ApoE4 carrier) is being performed only at baseline assessments. Cognitive, gait and balance assessments are being performed in all 12-month follow-up visits. From 2010 to 2021, 3Tesla Magnetic Resonance Imaging (structural and functional -resting state-) and MRI spectroscopy are being performed at four different time points: at baseline, month 18 and month 36, and month 60, following the Canadian Dementia Imaging protocol (http://www.cdip-pcid.ca.). Since 2021, the 18-month MRI timepoint changed to be performed at 12-month visit to align MRI timepoints with blood draw, which allows analysis of MRI and biomarker comparisons over time. For the 20-month Follow-Up period, MRI was performed at Year-2, Year-5 and Year-7 until 2018. Since 2018, the 20-Year Follow-Up MRI timepoints changed to Year-3, Year-5, Year-7 and Year-10. Blood and brain imaging were added after the second wave of the study, in 2010.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cognitively Normal (Control Group)
Participants aged 60 and older, with absence of Dementia (by DSM IV and DSM V) criteria. Normal age-, sex-, and education-adjusted performance on standardized cognitive tests, which are used to classify mild cognitive impairment (MCI) or prodromal AD.
No interventions assigned to this group
Subjective Cognitive Impairment (SCI)
Participants aged 60 and older, with absence of Dementia (by DSM IV and DSM V) criteria. Normal age-, sex-, and education-adjusted performance on standardized cognitive tests, which are used to classify mild cognitive impairment (MCI) or prodromal AD. Self-experienced persistent decline in cognitive capacity in comparison with a previously normal status and unrelated to an acute event. Answering "yes" to both of the following questions: "Do you feel like your memory or thinking is becoming worse?" and "Does this concern you?"
No interventions assigned to this group
Mild Cognitive Impairment (MCI)
Participants aged 60 and older that have self-experienced persistent decline in cognitive capacity and unrelated to an acute event. MCI is operationalized following Peterson's criteria as: i) presence of subjective memory complaints from the patient and family; ii) objective memory impairment in cognitive tests (below 1.5 SD on standardized cognitive tests adjusted by age, sex, and education-); iii) preserved activities of daily living (assessed using the Lawton-Brody scale); iv) absence of clinical dementia established using DSM-IV-TR (from 2007 to 2013) and DSM V (from 2014 and onwards)
No interventions assigned to this group
