Who could benefit from this research

Could help

Ideal participants are adults aged 40 or older living in South Africa, especially those in the Agincourt surveillance area, who can attend visits and agree to cognitive testing and possible blood draws or brain scans.

Less likely to help

People under 40, those living outside South Africa, or individuals unable or unwilling to attend study visits or provide blood samples or imaging would not be directly involved or benefit from participation.

What this research studies

You would be part of a long-term project that follows thousands of South African adults aged 40+ to watch how memory and thinking change over time. Participants complete standard interviews and validated neuropsychological tests at several waves to chart cognitive trajectories. A smaller, enriched subgroup gets brain imaging and blood tests for Alzheimer’s-related biomarkers, and all data are harmonized with international HRS/HCAP efforts for global comparisons. The project aims to produce the first national estimates of dementia in South Africa and to identify pathways that lead to cognitive decline.

Why it matters

Potential benefit: If successful, this work could provide the first national dementia estimates for South Africa and identify risk factors that help guide prevention and care.

How similar studies have gone: Large aging cohorts using the same HRS/HCAP methods have successfully produced prevalence and risk-factor findings in other countries, while applying these methods nationally in South Africa is relatively new.
