Topic: Risk, prevention and care in population studies
A decreasing linear trend was observed between higher levels of curry consumption and cognitive decline (p = 0.037). The cumulative incidence of MCI-dementia decreased from 13.1% in those who never or rarely consumed curry to 3.6% in those who consumed curry daily (linear p < 0.001). The adjusted OR across levels of curry consumption exhibited a linear trend (p = 0.021) from OR = 0.61 (p < 0.05) for occasional consumption to OR = 0.21 (p < 0.001) for daily consumption. The intake of dietary curcumin through curry shows a dose-dependent reduction in incidence of cognitive decline and MCI-dementia in this Asian population of community-based elders.

Key findings
- A decreasing linear trend was observed between higher levels of curry consumption and cognitive decline (p = 0.037).
- The cumulative incidence of MCI-dementia decreased from 13.1% in those who never or rarely consumed curry to 3.6% in those who consumed curry daily (linear p < 0.001).
- The adjusted OR across levels of curry consumption exhibited a linear trend (p = 0.021) from OR = 0.61 (p < 0.05) for occasional consumption to OR = 0.21 (p < 0.001) for daily consumption.
- The intake of dietary curcumin through curry shows a dose-dependent reduction in incidence of cognitive decline and MCI-dementia in this Asian population of community-based elders.
Why it matters
In this population-based cohort, higher curry consumption was linked in a dose-dependent way to lower incidence of cognitive decline and mild cognitive impairment or dementia. This is an observational association and cannot prove that curcumin or curry prevents dementia.
