Outline of Final Research Achievements

We investigated the effects of excess salt intake on silent brain infarction on MRI in a population-based cohort of 196 non-demented elderly subjects. After excluding cases with inadequate examinations, silent brain infarction was significantly associated with age and hypertension but not with salt intake (logistic regression analysis). In contrast, hypertension was associated with age, diabetes, body mass index (obesity), renal function, and particularly salt intake (OR 1.18, 95% confidence interval 1.05 – 1.32). Our findings indicate that excess salt intake may exert a detrimental effect on silent brain infarction through hypertension.
