Hypothesis
Does moderate to vigorous physical activity mitigate the negative impact of poor sleep on cognitive function in older adults with chronic stroke?
Conclusion
Moderate to vigorous physical activity helps preserve cognitive function in stroke survivors with shorter sleep duration, especially in males.
Supporting Evidence
- Stroke increases the risk for dementia two-fold.
- Moderate to vigorous physical activity is positively associated with cognitive function.
- Poor sleep quality is common after a stroke and may lead to cognitive impairment.
Takeaway
If you have had a stroke and don't sleep well, being active can help your brain stay sharp, especially for men.
Methodology
The study used wrist-worn actigraphy to measure physical activity and sleep duration, and assessed cognitive function with the ADAS-Cog in a randomized controlled trial.
Participant Demographics
Community-dwelling older adults with chronic stroke, average age 71 years, 38 females.
