Study Finds Statins Don’t Lead to Memory Problems

Concerns about statins’ effects on the brain emerged after a few older studies and case reports suggested that these drugs could cause memory problems.

Stopping Statins After Age 75: A Bad Idea?

For people older than 75 with no known cardiovascular disease (CVD), it’s been unclear whether statins are beneficial.

Smoking only a few cigarettes a day doesn’t mean you’re safe from declining lung function, according to a 2019 study in Lancet Respiratory Medicine.
