AHR increase in AD blood serum. We determined AHR in serum from the young, healthy elder, and AD patients. We found higher AHR concentration in AD patients (n = 29) than in young (n = 14) and elderly (n = 16) participants (A); microangiopathy (MAG, n = 10) is a comorbidity that decreases the AHR level in AD patients (B). Values are mean ± SEM. Statistics were performed by unpaired t-test. We did not detect significant differences in variances using an F-test.
