Curcumin and Yoga Therapy for Mild Cognitive Impairment

Recruiting

This study will determine the impact of two interventions in people with early memory problems. First, it will test the clinical benefits of curcumin, a compound isolated from turmeric root, a component of Indian curry spices that has been found to inhibit several potential pathways in Alzheimer's disease. Second, it will determine the effect of adding a yoga-based physical exercise program.

Mild cognitive impairment (MCI) often represents the earliest stage of Alzheimer's disease, as individuals with MCI are subsequently diagnosed with Alzheimer's at much higher rates than their cognitively normal peers. This year-long, Phase II study will help determine whether two interventions--dietary supplementation with a novel formulation of curcumin and an aerobic yoga exercise program--affect memory function in older adults with MCI. Researchers will also examine brain imaging results and blood-based biomarkers associated with Alzheimer's disease.

For the first 6 months, participants will take either a curcumin supplement (800 mg daily) or a placebo. For the next 6 to 12 months, they will add a yoga exercise program, either aerobic or nonaerobic (two 1-hour classes and two 30-minute, at-home sessions per week). Investigators will examine any synergism between curcumin supplementation and aerobic exercise.
