Midlife hypertension (HTN) contributes to cognitive decline in Alzheimer's disease (AD). However, the exact effect of late-life HTN on the AD pathology and on cognitive decline is still controversial. Here, we aimed to assess the impact of HTN and AD pathology in cognitively unimpaired (CU) individuals over 65 years of age on longitudinal cognitive decline. We evaluated 637 CU individuals from two independent cohorts (475 CU individuals from the ADNI cohort; and 162 CU individuals from the TRIAD cohort), with a follow-up of up to 6 years. Linear mixed-effects models showed that HTN and Aβ acted together to promote longitudinal cognitive decline, especially memory loss, in a synergistic way, with a dose-dependent association of blood pressure and Aβ pathology. Hence, HTN in late-life confers additional risk for cognitive decline, particularly for memory loss, in CU individuals at risk of developing dementia due to AD and is a potential modifiable risk factor even at older age.
