Summary
Physical inactivity, high blood pressure and dyslipidemia are risk factors for Alzheimer's disease (AD) and vascular dementia. Importantly, these risk factors are modifiable with lifestyle changes, pharmacological treatment, or both. The rrAD study will determine effects of aerobic exercise training and intensive vascular risk reduction on cognitive performance in older adults who have high risk for AD.
