Is Mediterranean–Dietary Approaches to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay (MIND) diet associated with hippocampal sclerosis (HS) and limbic-predominant age-related transactive response DNA-binding protein 43 encephalopathy neuropathological change (LATE-NC)?This cohort study of 809 autopsied participants found that MIND diet adherence was associated with lower odds of having HS, HS with LATE-NC, and hippocampal neuronal loss. The association between the MIND diet and HS partially mediated the association of MIND diet and cognition among autopsied participants.These findings suggest that consuming a healthy diet, such as the MIND diet, may decrease the likelihood of HS and may support hippocampal health.
