ABSTRACT
Previous studies suggested that Helicobacter pylori infection could be a risk factor for stroke, dementia, and Alzheimer's disease (AD). The authors examined data from participants, 60 years old and older in the Third National Health and Nutrition Examination Survey (NHANES-III) to assess the relation between Helicobacter pylori infection and results of the Mini-Mental State Examination (n = 1860) using logistic regression analysis controlling for age, gender, race/ethnicity, education, poverty and history of medically diagnosed diabetes. Moreover, we examined performance on the digit-symbol substitution test (DSST) of 1031 participants in the 1999-2000 NHANES according to their H. pylori infection status controlling for potential confounders using multiple linear regression analyses. In 1988-1991, older adults infected with CagA strains of H. pylori had a 50% borderline statistically significant increased level of cognitive impairment, as measured by low Mini-Mental State Examination (MMSE) scores (age-education adjusted prevalence ratio 1.5; 95% confidence interval 1.0, 2.0). In 1999-2000, older US adults infected with H. pylori scored 2.6 fewer points in the DSST than those uninfected (mean adjusted difference -2.6; 95% confidence interval -5.1, -0.1). The authors concluded that H. pylori infection might be a risk factor for cognitive decline in the elderly. They also found that low cobalamin and elevated homocysteine were associated with cognitive impairment.
