Keep those neurons firing and make new connections with brain exercises such as crossword puzzles, sudoku, learning a musical instrument or reading. I enjoy a good jigsaw puzzle from time to time and I read for pleasure, almost every day. 

As a family, we also follow some basic lifestyle approaches that are great for brain health: Anti Inflammatory diet (we include lots of cruciferous veggies, leafy greens, fish, berries, avocado, ghee, eggs, nuts, whole grains, grass fed meats and dark chocolate), probiotics for the gut-brain connection, adequate sleep and hydration.
