Key result
ARBs and thiazides are linked to ~7% lower Alzheimer's risk, while ACE inhibitors show higher risk.
Why the study?
Hypertension is a modifiable risk factor for Alzheimer's disease, and specific antihypertensive classes affecting the renin-angiotensin-aldosterone system may alter Alzheimer's disease risk.
Do specific antihypertensive medications alter the risk of incident Alzheimer's disease in Medicare beneficiaries?
Do specific antihypertensive medications alter the risk of incident Alzheimer's disease in Medicare beneficiaries?
ARBs and thiazide diuretics are associated with a reduced risk of incident Alzheimer's disease and may be the preferred antihypertensive agents in patients at risk for the disease.
May favor ARBs and thiazides over ACE inhibitors in at-risk patients; extends RAAS hypothesis but leaves causality open pending RCTs.
BACKGROUND Hypertension is a modifiable risk factor for Alzheimer's disease (AD). Specific antihypertensive classes may lower/increase AD risk by affecting the renin–angiotensin–aldosterone system. METHODS We investigated AD risk in relation to antihypertensive medications in a population‐based study of 33,714 incident AD cases and 897,872 controls from Medicare data. Multinomial logistic regression models were adjusted for age, sex, race/ethnicity, smoking probability, and health‐care use. We performed 3‐year exposure lagged, 90‐day continuous medication prescription, and proportion of days covered analyses. RESULTS Beneficiaries prescribed angiotensin receptor blockers (ARBs; odds ratios [ORs] 0.93, 95% confidence intervals [CIs] 0.91–0.95) or thiazides (OR 0.93, 95% CI 0.91–0.95) had an inverse association of developing incident AD, while beneficiaries taking angiotensin converting enzyme inhibitors (OR 1.08, 95% CI 1.06–1.11) had a positive association with developing incident AD. DISCUSSION ARB medications and thiazide diuretics may be the preferred antihypertensive in patients at risk of AD.

Laurido‐Soto et al. (2026) studied this question. Angiotensin receptor blockers (OR 0.93) and thiazides (OR 0.93) were associated with a lower risk of incident Alzheimer's disease, whereas ACE inhibitors (OR 1.08) were linked to a higher risk.
