  Purpose

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 not improve memory on their own without 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.

Primary Outcome Measures:
  • 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. [ Time Frame: 0, 6, and 12 months ] [ Designated as safety issue: No ]
    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. We will test whether supplements and/or exercise type are associated with a decrease in the biomarkers thought to be associated with MCI


Secondary Outcome Measures:
  • Changes in 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) glucose metabolism neuroimaging after supplementation compared to baseline and compared to placebo [ Time Frame: 0 and 6 months ] [ Designated as safety issue: No ]
    Functional connectivity multivariate discriminant analysis of neuroimaging changes using 18FDG-PET predicting rapid conversion to Alzheimer will be examined in subjects on supplements compared to those on placebo. Cerebral metabolism of glucose will be assessed for those receiving supplements vs. placebo and vs baseline (first six 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 [ Time Frame: 0, 6, 12 months ] [ Designated as safety issue: No ]
    Cognitive changes shown to precede Alzheimer's will be assessed using a neuropsychological battery. Behavioral symptoms will be assessed with the Neuropsychiatric Inventory Questionnaire (NPI-Q). Instrumental activities of daily living will be assessed with the Functional Activities Questionnaire. Overall assessment of disease severity will be assessed with the Clinical Dementia Rating Scale Sum of Boxes. subjects on supplements compared to those on placebo. Neuropsychiatric parameters will be assessed for those receiving supplements vs baseline or vs placebo or with those performing aerobic yoga with placebo or non aerobic yoga with curcumin (second six month period).

  • Number of Participants with Adverse Events [ Time Frame: 0,3,6,9,12 months ] [ Designated as safety issue: Yes ]
    We will perform routine comprehensive blood panel test to monitor safety and tolerability of Curcumin in subjects at risk for MCI by means of adverse events, vital signs and safety laboratory assessments. [ Time Frame: is at each timepoint in the study, 3, 6, 9 and 12 months].

Detailed Description:

Mild cognitive impairment (MCI) often represents the earliest stages of Alzheimer's disease (AD), as individuals meeting criteria for MCI are subsequently diagnosed with AD at much higher rates than their cognitively normal elderly peers. The goal of the current study is to determine whether dietary supplementation with a novel formulation of curcumin (a component of the curry spice turmeric), which is better absorbed and more efficiently transported into the brain, can alter biological and clinical markers associated with AD risk, and to determine whether the potential beneficial effects of curcumin supplementation are synergistic with aerobic exercise. We will recruit 80 elderly participants meeting criteria for MCI. Over the second 6 months of the study, the curcumin and placebo groups will be further divided into groups receiving training in either aerobic or non-aerobic yoga to determine the synergism between curcumin supplementation and aerobic exercise. The effectiveness of these interventions will be measured using plasma samples (for expression of Alzheimer-related biomarkers), and neuropsychological, functional, and behavioral assessments (i.e. clinical measures) collected at baseline, 6 months, and 12 months after initiation of treatments, with a subset of participants receiving brain imaging at baseline and 6 months. A modification was submitted to titer the study dosage two weeks prior to study start (1 capsule BID, first five days, then 2 capsules BID for five days, then 6 capsules BID for five days, then 8 capsules BID- study dosage). Over the first 6 months of the study, participants will be randomized into equal groups receiving dietary supplementation with either curcumin or placebo. Over the second 6 months of the study, participants will be further randomized into equal groups receiving dietary supplementation with either curcumin or placebo.
