A review of data from 19 published studies found that older adults either at risk for or diagnosed with Alzheimer’s disease who engaged in an aerobic exercise program experienced an improvement in their cognitive function. Interestingly, the researchers observed that participants who performed only aerobic exercise fared better in regards to mental function than those in an aerobic exercise plus resistance training group. The findings suggest that older adults who are at risk for or who have Alzheimer’s disease should focus on aerobic exercise over other types of exercise to help preserve the ability to think and make decisions.
