Abstract

The authors investigated the association between Helicobacter pylori infection (Hp-I) and Alzheimer disease (AD) by using histology for diagnosis of Hp-I. Fifty patients with AD and 30 iron deficiency anemic control participants without AD were included. The histologic prevalence of Hp-I was 88% in patients with AD and 46.7% in controls (p < 0.001).
