Beskrivelse
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:
- 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.
- Uncontrolled hypertension within the last 6 months
- History of cancer in the last 5 years (except non-metastatic basal or squamous cell carcinoma)
- History of drug or alcohol abuse as defined by DSM-IV criteria within the last 2 years
- Insulin-dependent diabetes mellitus
- Significant pain or musculoskeletal disorder prohibiting participation in an exercise program
- Unwillingness to undergo or contraindication to brain MRI scan.
- History within the last 5 years of primary or recurrent malignant disease with the exception of resected localized cutaneous squamous cell carcinoma, basal cell carcinoma, cervical carcinoma, or prostate cancer.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Amyloid Burden
Tidsramme: Baseline to 52 weeks
|
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.

Whole Brain Volume
Tidsramme: Baseline to 52 weeks
|
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.
|
Baseline to 52 weeks

|
Executive Function
Tidsramme: Baseline to Week 52
|
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.
