Walk 5000+ Steps Daily to Slow Alzheimer's
11 Feb
Summary
- Over 5,000 daily steps may slow cognitive decline and Alzheimer's protein buildup.
- A 14-year study found modest exercise benefits even those with early Alzheimer's markers.
- Activity slowed tau protein accumulation, a cause of brain cell loss.
New research suggests that incorporating over 5,000 steps into one's daily routine may help decelerate cognitive decline and the build-up of proteins associated with Alzheimer's disease. This finding stems from a comprehensive 14-year study, one of the first to link specific activity levels with key Alzheimer's markers.
Experts from Harvard analyzed data from 294 participants, aged 50 to 90. The study, published in Nature Medicine, indicated that individuals with early signs of Alzheimer's pathology in their brains could still benefit from moderate exercise. Participants wore pedometers and underwent cognitive assessments and brain scans over the study period.
The research revealed a connection between higher physical activity and a slower decline in thinking and memory skills. Furthermore, even moderate activity, around 3,001 to 5,000 steps daily, was associated with a slowdown in tau protein accumulation and cognitive decline. Experts noted that 5,001 to 7,500 steps appeared most beneficial.
While the study provides strong evidence for the benefits of physical activity on brain health, researchers caution that it doesn't guarantee prevention or slowing of dementia. Other lifestyle factors, such as a healthy diet and managing chronic conditions, also play a crucial role in reducing dementia risk.
