How regular cash support during adulthood affects memory and dementia risk in rural South Africa
Cumulative socioeconomic exposures, cash transfer interventions, and later-life cognitive decline and dementia risk in a low-income region of South Africa
This work looks at whether receiving government cash payments during adulthood helps protect memory and lower the chance of dementia for people in a low-income region of South Africa.

What this research studies
You would be part of research that combines long-running local population records, an aging cohort, and data from randomized cash transfer programs to see how money people receive across their lives relates to later memory and dementia. The team links individuals across a regional census, an adult aging study (HAALSI), and a prior randomized cash transfer trial to follow cognitive outcomes over time. They will study different amounts, lengths of time receiving payments, and which ages or groups benefit most to find the best ways cash transfers might protect the brain. The goal is to produce evidence that policymakers can use to design social programs that reduce dementia risk.
Who could benefit from this research
Good fit: Adults living in the low-income rural regions of South Africa covered by the linked cohorts, especially those who have received or could receive government cash transfer payments, are the ideal participants.
Not a fit: People who live outside the study region or whose cognitive problems are driven mainly by non-social causes (for example certain genetic conditions) may not directly benefit from these program-focused findings.
Why it matters
Potential benefit: If successful, the findings could guide cash transfer program designs that reduce memory decline and lower dementia risk for many people in low-income settings.
How similar studies have performed: Earlier work by this team found that randomized cash transfers were linked to better later-life memory and lower dementia probability, so this project builds on promising prior results to find the best program designs.
