That's the good news. The bad news is that grapefruit juice can interact with dozens of medications, sometimes dangerously.

What are the causes of MCI?

MCI is not dementia (see "What is dementia?"), but it's not normal thinking, either. It often stems from disease or treatments for disease, including
