Abstract Introduction Plant‐based diets confer health benefits, especially on the prevention of noncommunicable diseases. The relationship between plant‐based dietary patterns cognitive function as a neurological outcome needs more evidence. We aimed to assess associations and among Chinese older adults. Methods used four waves (2008–2018) Longitudinal Healthy Longevity Survey. included 6136 participants aged 65 years with normal cognition at baseline. constructed an overall diet index (PDI), healthful (hPDI), unhealthful (uPDI) from questionnaires. Mini‐Mental State Examination (MMSE) function. multivariable‐adjusted generalized estimating equation explore corresponding associations. Results models showed inverse highest quartiles PDI hPDI were associated 55% (odds ratio [OR] = 0.45, 95% CI: 0.39, 0.52) decrease 39% (OR 0.61, 0.54, 0.70) in odds impairment (MMSE < 24), compared lowest quartile. In contrast, quartile uPDI was increased risk 2.03, 1.79, 2.31) impairment. did not observe pronounced differences by selected socioeconomic status, physical activity, residential greenness, APOE ε4 status. Conclusions Our findings suggested that adherence healthy lower risks adults, unhealthy related higher
