To keep your mind sharp you need something called “cognitive reserve.” Cognitive reserve is a buffer of extra brain networks built by stimulating experiences.
Think of your brain as a forest. People with a lot of these networks have a dense forest. When Alzheimer’s disease comes in with a weed whacker, it can’t do as much damage.
The good news is that you can increase the density of your brain ‘forest’ at any time in your life.
Why? Your brain doesn’t know how old you are – and doesn’t care. Your brain just wants to be in a stimulating environment and that’s something you can do at any age.
Reading, writing, crossword puzzles, playing board or card games, participating in group discussions, learning a new language or sport and playing music all may help to keep your mind agile and “dense.”
