Key result
ARB exposure is linked to ~20% lower dementia risk vs ACE inhibitors in hypertension.
Why the study?
Research on the potential protective benefits of angiotensin II receptor blockers in preventing Alzheimer’s disease and related dementias and cognitive impairment has produced mixed and inconclusive results.
Does angiotensin II receptor blocker therapy reduce the risk of Alzheimer's disease and related dementias in patients with hypertension compared to ACE inhibitors or other antihypertensives?

“There is no cure for AD, ADRD, or vascular dementia; hence, these findings are significant in preventing those disorders in an inexpensive, convenient, and safe way. Limitations in claims data should be considered when interpreting our findings.”
In a massive cohort of hypertensive adults, treatment with ARBs—especially those that cross the blood-brain barrier—was associated with a significantly lower risk of incident ADRD and vascular dementia compared to ACE inhibitors, other antihypertensives, or no treatment.
Research on the potential protective benefits of angiotensin II receptor blockers (ARBs) in preventing Alzheimer’s disease and related dementias (AD/ADRD) as well as cognitive impairment has produced mixed and inconclusive results. This retrospective cohort study utilized Optum’s de-identified Clinformatics® Data Mart database and focused on hypertensive patients without any prior diagnosis of ADRD. Antihypertensive medication (AHM) categories were determined, and ARBs were further grouped accor

Schneider et al. (2026) conducted a cohort in Hypertension without prior Alzheimer's disease and related dementias (ADRD) (n=6,390,826). Angiotensin II Receptor Blockers (ARBs) vs. Angiotensin-converting enzyme inhibitors (ACEIs) was evaluated on Incident Alzheimer's disease and related dementias (ADRD) (HR 0.80, 95% CI 0.79, 0.80, p=< 0.0001). Among hypertensive patients, exposure to ARBs was associated with a 20% reduction in the hazard of incident Alzheimer's disease and related dementias compared with ACEI use.
