How can I maintain my memory as I get older?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
While normal predictable memory changes occur as we age, most people maintain their memory through the years. Starting in your late 20s, your hippocampus -- the part of your brain responsible for memory -- shrinks an average of 1% a year as memory cells shrivel up and die.

The good news: Shrinking is reversible. Exercise your memory cells with mental tasks that can save your hippocampal cells. Or, better yet, you can help your brain grow new cells. A recent study found that juggling isn't just a trick -- it can actually make your brain bigger! Just 15 minutes of juggling a day can result in a significant increase in your brain's gray matter. But like a muscle, you have to practice it regularly to benefit or you'll lose what you've gained.
