This study is collecting prospective data and is a longitudinal study, We are using identical data collection approaches used during the McCusker KARVIAH study(ACTRN12613000681752) for blood results, brain imaging, and lifestyle assessments. All the tools and questionnaires used are mentioned in the intervention/exposure section.

Description of intervention(s) / exposure
The previous KARVIAH_MK002 study recruited cognitively healthy participants aged 65-90 yrs of age to participate in a 12 month intervention of curcumin 1500mg daily (500mg capsules taken 3 times per day) or placebo (identical non-active ingredient capsules) for a period of 12 months.

The KARVIAH_XTND study is a non-intervention study will investigate the current physical and cognitive health of participants based on cognitive and memory function, physical assessment, blood, urine, lifestyle, and cerebral PET amyloid imaging.
Recruitment will include participants previously recruited for the KARVIAH study in addition to new participants.

The KARVIAH_XTND will undertake cognitive assessments, collect blood and urine samples, and undertake health and lifestyle review, vital signs, gait and grip strength, in addition to brain (PET amyloid-beta) imaging.
Measures used for memory and cognitive function will include:
MoCA, Geriatric Depression Scale (GDS), Rey Auditory Verbal Assessment Long term memory (RAVALT), Clinical Dementia Rating (CDR) (sum of boxes), Depression, Anxiety and Stress (DASS), Wechsler Test of Adult Reading (WTAR); Mini-mental state examination (MMSE); Category fluency; Controlled Oral Word Association; Boston Naming Test; Digit Span test; Digit Symbol test. - all conducted annually.

Questionnaires: Assessment of Memory Complaint Questionnaire (MAC-Q) - Annual
Neuroticism-Extroversion-Openness Five Factor Inventory Personality Inventory - Once only
Prospective and Retrospective Memory Questionnaire (PRMQ) - Annual
Subjective Cognitive Impairement Questionnaire - Annual
Pittsburgh Quality Sleep Index - Annual
Community Healthy Activities Model Program for seniors - Annual
Food Frequency Questionnaire - Annual
Physical health will be assessed using:
Mini Sarcopaenia Risk assessment - Annual
SF 36- Annual

Informant questionnaire (optional)

Alzheimer's Disease Cooperative Study - Activities of Daily living - annual
Dysexecutive Questionnaire - annual
Informant Questionnaires of Cognitive Decline in the Elderly - annual

All tests will be undertaken annually for a period of 3 years Post intervention (Kx0, 12, 24, 36 months), except for the PET amyloid brain image which is scheduled at Kx0 and the end of study. The PET image will measure the Standard Uptake Value Ratio of 18F-Florbetaben to assess cerebral amyloid-beta load.

Some information including medical health updates, and questionnaires can if preferred by the participant, conducted over the telephone to reduce the onsite length of visit, however, the cognitive testing, blood draw, vital signs and brain imaging, will require a face to face appointment.
Cognitive assessments are conducted by experienced raters, trained and supervised by a clinical neuropsychologist on the study.
Clinical assessment and governance is provided by the PI or nominated medical Sub-I.
The annual visit is expected to take up to 4 hours, with the all assessments undertaken (excluding brain imaging) at the KaRa Institute of Neurological Diseases, 35-41 Waterloo Road, Macquarie Park, 2113, NSW. Imaging procedures are conducted at the Macquarie Health Imaging Facility, Macquarie University, Macquarie Park.

Data collected in this study will be compared with previous data (blood, cognitive, lifestyle and PET amyloid imaging from the earlier McCusker KARVIAH study (completed 2016)

Primary outcome [1] 319041 0
Evaluate the predictive value of pre-clinical biomarkers previously published during the KARVIAH study as measured by blood biomarker compared with the brain amyloid levels (measured using 18F-Florbetaben standard uptake value ratio (SUVR). SUVR range is considered high if equal to or greater than 1.35; SUVR is low if less than 1.35.
Blood biomarkers including serum and plasma ferritin, and phospholips were analysed as a continuous variable, and compared with the PET imaging results. The biomarkers are under research and no derfinite range is yet developed.
This outcome will be assessed in all participants.

Statistical methods / analysis
Results will be compared in the IBM SPSS Statistics software package using Generalised Linear Models. The pre-intervention (baseline) values will be used as a covariate in the analysis. Other covariates that will be considered include age, sex, education, APOE e4 status. Post-hoc comparison of means will be performed if the overall treatment comparison in the analysis of variance is significant. A two-way analysis of variance and multivariate analysis of variance will be used. Correlations between the various measures within each group will be assessed using Partial Pearson correlation coefficients.

Brief summary
The earlier KARVIAH Project recruited (n= 105) participants who took either curcumin or placebo orally for a period of 12 months. Participants were between the ages of 65-90 years living in retirement living accommodation or similar. Each participant undertook a health review, including general demographics, age, education, health and medication history and vital signs. During the study a comprehensive cognitive assessment was taken, blood drawn, lifestyle questionnaires completed (exercise, nutrition and sleep quality), as well as cerebral Magnetic Resonance Imaging (MRI); amyloid beta positron emission tomography (Aß- PET) and fluorodeoxyglucose (FDG-PET),

The KARVIAH_XTND study will investigate biomarkers and longitudinal quality of life measure post curcumin intervention, as well as non-modifiable and modifiable lifestyle and health risk factors which may influence cognitive function.
