The participants, including high-performing elderly (SuperAgers), normal ageing elderly and neurocognitive disorder (NCD) patients will be re-invited from our previous cohort (2013-2014) (N=488).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* SuperAgers are determined by the scores of global cognitive function. This ensured that the participants are divided by a measure relevant to the current study without directly biasing the results toward the domain of interest;
* Normal aging: the cases with the scores of cognitive performance within 1.5 standard deviation (SD) of age and education matched normative values derived from our cohort study, of which presented with HK MoCA score greater than 26 and CDR score equal to 0;
* NCD patients are defined as: evidence of modest decline in one or more cognitive domains, which is set as ≥ 1.5 SD below the age- and education-adjusted normative scores; no interference with independence in everyday activities; and no comorbid major psychiatric disorders.
Exclusion Criteria:
* History of bipolar disorders or psychosis;
* History of major neurological deficits including stroke, transient ischemic attack or traumatic brain injury;
* Comorbidities with depressive symptoms.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Global cognition will be measured by the Montreal Cognitive Assessment Hong Kong version (HK MoCA)
Timeframe: 2022-2024
2
Complex attention will be measured by Attention Network Test (ANT)
