Risk Reduction for Alzheimer's Disease
United States513 participantsStarted 2017-02-02
Plain-language 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.

Inclusion criteria
✓. Age 60-85, all races/ethnicities, and both sexes are eligible.
✓. a) A positive family history of dementia defined as having at least one first-degree relative with a history of AD or other type of dementia,or b) having subjective cognitive decline.
✓. Mini-Mental State Exam (MMSE) ≥ 26 to exclude gross dementia.
✓. Must lead a sedentary lifestyle defined by not having an "active" rating on Rapid Assessment of Physical Activity (RAPA), i.e., score below 6 on RAPA.
✓. a) Individuals treated for HTN with 110 ≤ SBP ≤ 130 mmHg; or b) Individuals with SBP \> 130 and SBP \< 180 (If an individual, not treated for HTN, has a SBP ≥ 125 mmHg, consider rescreening after 24 hours).
✓. Willingness to be randomized into the treatment groups and ability to return to clinic for follow-up visits over 24 months.
✓. Fluency in English, adequate visual and auditory acuity to allow neuropsychological testing.
✓. Participants must have a regular healthcare provider.
Exclusion criteria
✕. Clinically documented history of stroke, focal neurological signs or other major cerebrovascular diseases based on clinical judgment or MRI/CT scans such as evidence of infection, infarction or other brain lesions.
✕. Diagnosis of AD or other type of dementia, or significant neurologic diseases such as Parkinson's disease, seizure disorder, multiple sclerosis, history of severe head trauma or normal pressure hydrocephalus.

✕. Evidence of severe major depression (GDS \> 12, may be rescreened after 12 weeks or longer if evidence of reactive depression or temporary mood disturbances) or clinically significant psychopathology(e.g. psychosis and schizophrenia); if hospitalized in past year, can be rescreened in 6 months; or presence of a major psychiatric disorder that in the investigator's opinion, could interfere with adherence to research assessments or procedures.
✕. Unstable heart disease based on clinical judgment (e.g., heart attack/cardiac arrest, cardiac bypass procedures within previous 6 months and congestive heart failure),or other severe medical conditions.
✕. History of atrial fibrillation and evidence on ECG with any of the following: active symptoms of persistent palpitation, dizziness, history of syncope, chest pain, dyspnea, orthopnea, shortness of breath at rest, or paroxysmal nocturnal dyspnea within the past 6 months; resting heart rate of \< 30 or \> 110 bpm; taking class I or III anti-arrhythmic drugs including flecanide, propafenone, dronedarone, sotalol, dofetilide, and amiodarone; or clinical concerns for safely participating in exercise and lowering blood pressure.
✕. Systolic BP equal or greater than 180 mmHg and/or diastolic BP equal or greater than 110 mmHg, may be rescreened in 1 week.
✕. Orthostatic hypotension, defined as the third standing SBP \< 100mmHg, may be rescreened after 2 weeks.
✕. History of significant autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis, or polymyalgia rheumatic.
