Walking Exercise for Mild Cognitive Impairment
(EXEC Trial)
Trial Summary
What is the purpose of this trial?
The purpose of this study is to see if 6 months of home-based walking will improve memory, and brain structure and function, compared to health education in older adults that have chronic kidney disease and mild cognitive impairment.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if you have a major psychiatric disorder or unstable clinical depression, medication adjustments within 3 months of enrollment may affect eligibility.
What data supports the effectiveness of the treatment Walking Exercise for Mild Cognitive Impairment?
Is walking exercise safe for people with mild cognitive impairment?
How is home-based walking exercise different from other treatments for mild cognitive impairment?
Home-based walking exercise is unique because it is a low-cost, low-technology treatment that can be done at home, making it accessible and easy to incorporate into daily life. Unlike other treatments that may require special equipment or settings, walking is simple and has been shown to improve cognition and mobility in older adults.48101112
