Key result
The use of antihypertensive drugs, including ARBs, ACE inhibitors, calcium channel blockers, and beta blockers, was associated with a decreased incidence of dementia (ORs ranging from 0.74 to 0.89).
Why the study?
There has been growing interest in evaluating the relationship between the use of antihypertensive drugs and the incidence of dementia in elderly patients.
Does the use of antihypertensive drugs reduce the incidence of dementia in elderly patients ≥60 years?
Case-Control (n=24,810)
Yes
Does the use of antihypertensive drugs reduce the incidence of dementia in elderly patients ≥60 years?
Effect estimate: ORs ranging from 0.74 to 0.89
The use of various classes of antihypertensive drugs is associated with a reduced risk of developing dementia in elderly patients.
Antihypertensive use may link to lower dementia incidence in elderly patients; leaves open causation versus confounding in this observational analysis.
BACKGROUND: In recent years, there has been a growing interest in the association between the use of antihypertensive drugs and the incidence of dementia. OBJECTIVE: The goal of this retrospective study was to investigate the relationship between antihypertensive drug use and dementia in elderly persons followed in general practices in Germany. METHODS: This study included patients ≥60 years with documented blood pressure values who were diagnosed with dementia in general practices in Germany for the first time between 2013 and 2017 (index date). Dementia cases were matched to non-dementia controls using propensity scores based on age, sex, index year, and co-diagnoses. The main outcome of the study was the incidence of dementia as a function of the use of antihypertensive drugs. RESULTS: The present study included 12,405 patients with dementia and 12,405 patients without dementia. The use of angiotensin II receptor blockers (odds ratios [ORs] ranging from 0.74 to 0.79), angiotensin-converting enzyme inhibitors (ORs ranging from 0.85 to 0.88), calcium channel blockers (ORs ranging from 0.82 to 0.89), and beta blockers (OR = 0.88) was associated with a decrease in dementia incidence. CONCLUSION: Antihypertensive drug use is negatively associated with dementia in elderly persons followed in general practices in Germany.

Bohlken et al. (2019) conducted a case-control in Dementia (n=24,810). Antihypertensive drugs vs. Non-use of antihypertensive drugs was evaluated on Incidence of dementia (ORs ranging from 0.74 to 0.89). The use of antihypertensive drugs, including ARBs, ACE inhibitors, calcium channel blockers, and beta blockers, was associated with a decreased incidence of dementia (ORs ranging from 0.74 to 0.89).
