Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective follow-up study conducted at the Department of Psychiatry, The Chinese University of Hong Kong. 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).

Detailed Description

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Superagers

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.

Ageing

Intervention Type DIAGNOSTIC_TEST

Using comprehensive cognitive tests to quality the domain-specific cognitive changes during ageing.

Normal ageing elderly

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

Ageing

Intervention Type DIAGNOSTIC_TEST

Using comprehensive cognitive tests to quality the domain-specific cognitive changes during ageing.

Neurocognitive disorders patients

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.
