My 12 steps to a sharper mind — by the top brain surgeon

Dr. Sanjay Gupta, a neurosurgeon and CNN's chief medical correspondent, emphasizes the importance of prioritizing brain health alongside physical fitness. He suggests that with simple lifestyle tweaks, one can feel appreciably sharper, less anxious, more productive, better rested, and more energized within just three months. Gupta's book, "12 Weeks to a Sharper You," outlines a "brain-friendly" lifestyle, which includes:

1. Following the MIND diet
2. Cutting out added sugar and artificial sweeteners
3. Reducing salt intake
4. Drinking plenty of water
5. Avoiding prolonged sitting
6. Engaging in regular brisk walking
7. Practicing deep breathing exercises
8. Trying analytical meditation
9. Getting sufficient sleep
10. Using your non-dominant hand for cognitive stimulation
11. Flossing twice daily for dental and brain health
12. Prioritizing social connections and relationships

Gupta's approach focuses on small, incremental changes that can be incorporated into daily life to promote brain health and reduce the risk of dementia.
