Statin drugs: Can they cause memory problems?

There have been rare cases of memory loss reported in people who take statin drugs, such as Lipitor. But these reports were anecdotal and have not been substantiated by formal testing of cognitive function. In most of these cases, memory improved after the individuals stopped taking the statins. However, it's not clear whether the statins caused the memory problems.

Although some studies suggest that statins may actually reduce the risk of dementia, two large studies examining the potential health benefits of cholesterol-reducing medications found no effect on cognitive function from these drugs.

It's important to recognize that any potential risk of memory loss from statins is very small compared with the benefit these medications provide in preventing heart attack and stroke.

If you take a statin drug and notice any changes in your memory, discuss your concerns with your doctor.
