Blood Pressure Drugs Tied to Decreased Dementia Risk

Blood Pressure Drugs Tied to Decreased Dementia Risk

A new study suggests that taking certain blood pressure medications may reduce the risk of dementia due to Alzheimer’s disease.

When researchers at Johns Hopkins analyzed data on more than 3,000 elderly Americans, they found that people over the age of 75 with normal cognition who used diuretics, angiotensin-1 receptor blockers (ARBs) and angiotensin-converting enzyme (ACE) inhibitors showed a reduced risk of Alzheimer’s-related dementia by at least 50 percent.

Additionally, diuretics were associated with a 50 percent reduced risk in those with mild cognitive impairment.

Beta blockers and calcium channel blockers did not show a link to reduced risk, the scientists reported in the study, published in the journal Neurology.

“Identifying new pharmacological treatments to prevent or delay the onset of AD dementia is critical, given the dearth of effective interventions to date,” said Sevil Yasar, M.D., Ph.D., assistant professor of medicine in the Department of Geriatric Medicine and Gerontology at the Johns Hopkins University School of Medicine. “Our study was able to replicate previous findings, however, we were also able to show that the beneficial effect of these blood pressure medications are maybe in addition to blood pressure control, and could help clinicians in selecting an antihypertensive medication based not only on blood pressure control, but also on additional benefits.”
