Statins have no apparent link to cognitive problems or dementia
Research we're watching
Cognitive (thinking) problems and dementia affect about one in 10 Americans over age 60. The possible influence of cholesterol-lowering statins on these conditions has garnered considerable attention over the years. But the latest findings on the matter are reassuring for older adults who take these medications.
The study included nearly 19,000 people ages 65 and older who were part of a separate trial of low-dose aspirin. When the study began, all the participants had normal cognitive ability and no heart-related problems, and about one-third were taking statins.
After an average follow-up of nearly five years, researchers found no differences in the incidence of dementia, cognitive problems, memory, language ability, or related issues between people who took statins and those who did not take the drugs. The study appeared in the June 29, 2021, Journal of the American College of Cardiology.
