The trial, sponsored by the University of Calgary, aims to evaluate the efficacy of a six-month aerobic exercise intervention for older adults aged 50-80 at increased risk of ADRD. Given the projected economic burden of dementia in Canada, estimated at $800 billion by 2038, successful outcomes could lead to significant healthcare savings and a shift in preventive strategies for dementia. The intervention's design, which incorporates stakeholder input from Alberta Health Services, suggests a strong potential for integration into clinical practice. If successful, this could position the University of Calgary as a leader in dementia prevention strategies, opening avenues for partnerships with healthcare providers and potential funding from governmental and non-governmental organizations focused on aging and cognitive health.
