Brief summary

This study examines the effect of curcumin taken orally, within a broader study investigating curcumin in the prevention of Alzheimer's disease. Participants will be allocated to either, no treatment or curcumin, for a period of 3-6 months. At the beginning and conclusion of the study, they will be required to undertake a brief cognitive assessment, answer lifestyle questions and donate blood. A once only mouth swab will also be taken. The intention of the study is to measure the influence of curcumin on the expression of inflammatory genetic markers, to examine if it is useful in reducing inflammation, by measuring associated proteins in the blood. The influence of curcumin on existing lifestyle patterns including sleep, activity levels and nutrition will also be examined through questionnaires at the end of the study.

Interventions

Arm 1: Healthy older people (n=12) will consume oral curcumin in capsule formulation, 1.5mg daily (x 3 divided doses) for a period of 3 or 6 months (optional extension by participant). Arm 2: Mild Cognitive Impairment (n=12) will consume oral curcumin, in capsule formulation 1.5mg daily (x 3 divided doses) for a period of 3 or 6 months (optional extension by participant). Adherence will be assessed by a capsule count at the 3 month TP and again at 6 months (if the optional extension has been e

Adherence will be assessed by a capsule count at the 3 month TP and again at 6 months (if the optional extension has been elected). Monthly phone calls will be made to the participant to monitor self-reported compliance.
