Study summary

The purpose of this study is to learn about the possible benefits of aerobic exercise in controlling or reducing the amount of amyloid present in the brain, reducing changes in brain structure that may lead to Alzheimer's Disease (AD), and increasing cognitive ability in individuals that have amyloid deposits and are at risk to develop AD.

Inclusion criteria

  • Clinical Dementia Rating 0 (nondemented)
  • Age 65 or older
  • Florbetapir PET evidence of cerebral amyloidosis
  • Sedentary or underactive by the Telephone Assessment of Physical Activity
  • Stable doses of medications for 30 days.
  • Clinician judgment regarding subject's health status and likelihood to successfully complete the 1-year exercise intervention

Exclusion criteria

Exclusion Criteria:

  • Clinically significant major psychiatric disorder (e.g., Major Depressive Disorder) according to standard criteria or significant psychiatric symptoms that could impair the completion of the study
  • Clinically-significant systemic illness that may affect safety or completion of the study
  • History of clinically-evident stroke
  • Clinically-significant infection within the last 30 days
  • Active cardiac condition (e.g. angina, myocardial infarction, atrial fibrillation) or pulmonary condition in the past 2 years that, in the investigator's opinion, could pose a safety risk to the participant-unless cleared for exercise by the participant's primary care physician or cardiologist.

What researchers measure

Primary outcomes

  1. Amyloid Burden

    Amyloid burden measure is mean Florbetapir cortical-to-cerebellar uptake ratio averaged across 6 regions of interest (frontal, temporal, parietal, anterior cingulate, posterior cingulate, and precuneus). Higher numbers mean more amyloid accumulation. There is no defined maximum value. Zero is the theoretical minimum value.

    Time frame: Baseline to 52 weeks

Secondary outcomes

  1. Whole Brain Volume

    Whole brain volume in mL define by Freesurfer analysis. Higher numbers indicate greater brain volume. There is no defined maximum. Zero is the theoretical minimum.

    Time frame: Baseline to 52 weeks

  2. Executive Function

    Executive Function ability to be measured using confirmatory factor analysis (CFA). CFA aggregates scores from across multiple subtests. Values are standard deviations centered on a pooled baseline (all participant scores at baseline). Higher values mean improvement over baseline testing. Lower scores (including negative) mean worse performance after baseline testing. There is no minimum or maximum score.

    Time frame: Baseline to Week 52
