  D) Our whole brain starts shrinking。

  And the best defense against memory loss is to try to prevent it by building up your brain‘s cognitive reserve, Daffner says。

  The brain ages just like the rest of the body。 Certain parts shrink, especially areas in the brain that are important to learning, memory and planning。 Changes in brain cells can affect communication between different regions of the brain。 And blood flow can be reduced as blood vessels narrow。

  Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about。 But if you forget the plot of the movie or don‘t remember even seeing it, that’s far more concerning, Daffner says。
