Adherence
Aerobic exercise does not significantly improve memory or executive function scores in early Alzheimer's disease compared to stretching and toning.
Do not expect aerobic exercise to directly reverse memory loss or improve executive function scores in early Alzheimer's. The primary benefit observed in this study was the maintenance of functional ability (ability to perform daily tasks). Exercise should be prescribed for functional preservation rather than cognitive enhancement.
GoodRefutesMEDIUM confidence
There was no clear effect of intervention on other primary outcome measures of Memory, Executive Function, or depressive symptoms.
Why this rating
RCT design, but underpowered for primary cognitive outcomes (pilot study).
