Published in the Vancouver Sun. For those with mild cognitive impairment caused by mini-strokes, exercise is the best medicine VANCOUVER — Taking regular brisk walks improves brain function in people who have already had mini-strokes, according to newly released findings by University of British Columbia researcher Teresa Liu-Ambrose. It’s more evidence that shows physical exercise is an effective way to prevent or slow the progress of dementia, says Liu-Ambrose, who is presenting the research for the first time Thursday at the Alzheimer’s Association International Conference in Washington, D.C., the world’s largest gathering of experts on Alzheimer’s and other dementias. “We’re quite keen to focus on vascular dementia because it … Read more
Mobility predicts change in older adults’ health-related quality of life: evidence from a Vancouver falls prevention prospective cohort study.
July 15, 2015
Health and Quality of Life Outcomes 2015, 13:101. Older adults with mobility impairments are prone to lower quality of life due to mobility impairments. Mobility, one’s ability to walk about may be important in contributing to your quality of life. As such, promoting mobility through intervention such as falls prevention may positively contribute to older adults’ quality of life. Background Older adults with mobility impairments are prone to reduced health related quality of life (HRQoL) is highly associated with mobility impairments. The consequences of falls have detrimental impact on mobility. Hence, ascertaining factors explaining variation among individuals’ quality of life is critical for promoting healthy ageing, particularly among older fallers. Hence, the … Read more

Published in the Research Insider, Vancouver Coastal Health Research Institute Although it may seem counter-intuitive, looking ‘below the neck’ for signs of cognitive decline before obvious symptoms appear is potentially a highly effective and accessible alternative to high-level cognitive neuroimaging or neurpsychological assessments. A new study by Vancouver Coastal Health Research Institute scientist Dr. Teresa Liu-Ambrose reveals that simple measures of physical function, such as a person’s ability to balance, to walk, or their strength level, are strongly related to subtle changes in cognitive status and may predict cognitive function in the future. “We’re recognizing that dementia is a disease that probably develops over 20 to 30 years – it’s not necessarily … Read more
Examining the effect of the relationship between falls and mild cognitive impairment on mobility and executive functions in community-dwelling older adults.

J Am Geriatr Soc. 2015 Mar;63(3):590-3. doi: 10.1111/jgs.13290. Background Cognitive impairment and falls are geriatric “giants” that significantly increase morbidity and mortality in older adults. Even mild cognitive impairment (MCI) is a significant risk factor for falls. Clinical gait abnormalities including slow gait and falls are early biomarkers of cognitive impairment, suggesting that impaired cognitive function and mobility share common underlying pathophysiology. Despite the vast interest in the interplay between impaired cognitive function and mobility, few studies to date have investigated whether their co-manifestation results in a broader and greater degree of deficits, potentially due to greater burden of pathology, than singular domain (i.e., cognitive or mobility) impairment. Understanding the specific and … Read more
