Why exercise is the best medicine for your brain

May 18, 2017

Originally published in the LA Times. Given time, any brain can succumb to dementia — memories fade, thoughts scatter, basic abilities wither on the vine. Brains don’t come with lifetime guarantees, but there is one major step you can take to protect yourself from Alzheimer’s or other causes of mental decline: exercise your body. Nothing protects the brain quite like regular exercise, says Jennifer Heisz, a cognitive neuroscientist at McMaster University in Ontario, Canada. Not crossword puzzles, not supplements, not prescription medications. Exercise seems to beat them all, reducing the risk of Alzheimer’s disease or cognitive decline by about 35% to 45%, according to the latest evidence. “It’s a strong message,” Heisz says. “We … 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

Examining the effect of the relationship between falls and mild cognitive impairment on mobility and executive functions in community-dwelling older adults.

March 20, 2015

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

Reduce falls by improving cognitive function

August 6, 2013

Originally published at UBC CPD, by Dr. Teresa Liu-Ambrose What I did before Falls are a common geriatric syndrome and are the third leading cause of chronic disability worldwide. Falls are not random events and occur, at least in part, due to impaired physiological function, such as impaired balance, and cognitive impairment. Primary care physicians can use the Physiological Profile Assessment screening tool – it has normative data (65 and up) and provides information for patients as well.1 Results from both systematic reviews and meta-analyses highlight that exercise can play an important role in falls prevention.2 The Otago Exercise Program (OEP) – a physical therapist-delivered, or nurse-delivered, progressive home-based strength and … Read more
