Dietary Sodium/Potassium Intake Does Not Affect Cognitive Function or Brain Imaging Indices.

ABSTRACT: BACKGROUND:Dietary sodium may influence cognitive function through its effects on cerebrovascular function and cerebral blood flow. METHODS:The aim of this study was to evaluate the association of dietary sodium intake with cognitive decline in community-dwelling older adults. We also evaluated the associations of dietary potassium and sodium:potassium intake with cognitive decline, and associations of these nutrients with micro- and macro-structural brain magnetic resonance imaging (MRI) indices. In all, 1,194 participants in the Health Aging and Body Composition study with measurements of dietary sodium intake (food frequency questionnaire [FFQ]) and change in the modified Mini Mental State Exam (3MS) were included. RESULTS:The age of participants was 74 ± 3 years with a mean dietary sod
