NCT01811381

Brief Summary

Physical exercise has proven to improve memory including in the elderly. Drugs developed to stop the underlying disease processes that cause Alzheimer's disease may succeed only with multimodal efforts to stimulate brain function. One purpose of the study is to test the clinical benefits of curcumin, a safe and effective compound isolated from the turmeric root (a component of Indian curry spices), which has been found to inhibit several potential disease pathways in Alzheimer's disease. Another purpose of this study is to determine how the addition of a physical exercise program in individuals with early memory problems may affect memory function or brain imaging and blood-based markers associated with Alzheimer's disease.

Outcome Measures

Primary Outcomes (1)

  • Curcumin effects (first six month period) or curcumin and aerobic yoga effects (second six month period) on the changes in the levels of blood biomarkers for Mild Cognitive Impairment relative to baseline or relative to placebo or non-aerobic yoga.

    Blood samples at baseline \& follow-ups are collected \& analyzed for changes in biomarkers associated with MCI and/or curcumin: Clusterin, C-reactive protein, N-terminal prohormone of brain natriuretic peptide, Apolipoprotein E, beta-amyloid, vascular cell adhesion molecule protein-1, Brain derived neurotrophic factor, Interleukin-6, Interleukin-1 beta, Interleukin 1 receptor accessory protein-like 2, Tumor necrosis factor alpha, Osteopontin. The investigators will test whether supplements and/or exercise type are associated with a decrease in the biomarkers thought to be associated with MCI

    0, 6, and 12 months

Secondary Outcomes (3)

  • Changes in 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) glucose metabolism neuroimaging after supplementation compared to baseline and compared to placebo

    0 and 6 months

  • Curcumin effects on changes in Neuropsychological parameters compared to baseline and to placebo (first six month period) and in combination with aerobic yoga, compared to baseline and to non-aerobic yoga with curcumin or aerobic yoga with supplement

    0, 6, 12 months
