Xing Y, Sun Y, Wang S, et al. - Ambulatory blood pressure (BP) monitoring (ABPM)-based BP control is very important for prevention of cognitive dysfunction progression in elderly.

• 305 elderly participants aged ≥65 years participated.

• A dipper pattern, nocturnal BP rise, and a non-dipper pattern was detected in 13.1%, 45.6%, and 41.3%, respectively, using ABPM.

• A greater cognitive impairment (CI) was seen in those elderly patients who experienced nocturnal BP rise.

• CI significantly elevated all-cause mortality in the elderly, but the nocturnal BP rise did not.

• 35 all-cause deaths and 33 cases of major adverse cardiac and cerebrovascular events were revealed after 2.03 years of follow-up.

• All-cause mortality in elderly was not significantly predicted by nocturnal BP rise.
