Several studies have documented recovery from statin-induced memory loss. Over 50 percent of people experience immediate improvement when they stop taking the medication, though others may have to wait weeks or months before they begin to feel normal again. Recovery length appears to depend on the length of time you were taking statins before symptoms developed--the longer you were taking them, the longer recovery will be.

On the Other: Underlying Causes

The people most likely to be taking statins are already at a higher risk for memory loss because of age and cardiac issues. If these factors are contributing to your memory issues, recovery is less certain. However, memory exercises can be effective in reversing problems caused by aging or health. Rarely, underlying issues may prevent someone from recovering their memory even after they stop taking statins.

Bottom Line

For most people, it is likely that they will recover fully from statin-induced memory loss, as long as there are no underlying issues. A small number will continue to experience problems, though, and there is no guarantee that you won't be in that group. As with any medical issue, your best course of action is to discuss your concerns with an expert.
