Motor slowing and cognitive slowing are more prevalent as we age. Importantly, the presence of both in an older person increases their risk of having dementia by ten times. Currently, there are no clinically meaningful predictors of progression to dementia in people with mild cognitive impairment (MCI). The main hypothesis is that subtle variations in gait while performing a simple cognitive task is a reliable, easy to perform, and feasible methodology to detect those older adults at higher risk of progression to dementia and also, at higher risk of further mobility decline and falls. 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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Progression to Dementia | The primary outcome is "progression to dementia" ascertained by clinician investigator using DSM-IV-TR (from 2007 to 2013) and DSM V (from 2014 and onwards). At the time of diagnosis, clinicians are blinded to baseline gait or baseline neuro-psychological test scores. Participants are being re-assessed after six months of the time point of ascertainment of dementia to confirm dementia status. | 25 years of follow-up | |
Primary | Type of Dementia | Type of dementia is being established using standardized criteria for Alzheimer's disease (AD) dementia, frontotemporal dementia, Lewy body dementia, and vascular dementia (VaD). | 25 years of follow-up | |
Secondary | Development of Mobility Decline | It is expected that MCI individuals with higher gait variability at baseline will develop mobility decline, defined as incident slowing in gait velocity (cm/s) by 10 cm/s | 25 years of follow-up | |
Secondary | Incidence of Falls | Falls is defined as 'an unintentionally coming to rest on the ground, floor, or other lower level and not due to a seizure or an acute stroke. Recurrent falls are defined as two or more events in a 12 months period. This outcome will be analyzed as the rate of falls over 36 months (defined as number of falls person-time at risk), the proportion of participants who fall (0, 1) and the proportion of recurrent fallers (2+ falls). | 25 years of follow-up | |
Secondary | Brain anatomical changes (grey matter) | Changes in grey matter volume are being as absolute change (in cm3) across assessments | 25 years of follow-up | |
Secondary | Brain anatomical changes (white matter) | Changes in white matter volume is being evaluated as absolute change (in cm3) across assessments. | 25 years of follow-up | |
Secondary | Brain anatomical changes (ventricular volume) | Changes in ventricular volume is being evaluated as absolute change (in cm3) across assessments | 25 years of follow-up | |
Secondary | Mortality | When a participant pass away informed/documented by caregiver or medical record | 25 years of follow up |
