Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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 elected). Monthly phone calls will be made to the participant to monitor self-reported compliance.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Healthy participants (n=12) will be drawn from in the Primary MK002 (n=100), who are not involved in the intervention of the primary study.
These participants will be offered involvement in the sub-study.

MCI participants will be recruited through the process of screening within our primary study. Those assessed as MCI would not be eligible for the primary study, so can be offered the sub study. Other MCI participants will be contacted from our research database).

Allocation will be done by contacting via computer/phone an "off site" administrator, within another state, at a central research office.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A remote site, computer generated randomisation process will be used to allocate intervention or non-intervention to those recruited in the study, within each MCI and HC groups.

Statistical methods / analysis
In the current study, the main outcome variable used to assess differences between the two open label intervention groups and two non-intervention groups are epigenetic changes in inflammatory gene expression, as measured within the blood.

Using the G*Power software (version 3.1.5) for Power analysis (1 - Beta) indicated a sample size N equals 12 per group is required to detect any significant differences between groups at greater than/ equal to 80% power and alpha equal to 0.05. The analysis may include 4 covariates (age, gender, APOE e4 allele status, education) and a commonly used F test (e.g. ANCOVA).
