Sanjay Gupta
"The neurosurgeon making brain health a matter of daily choices, not just genetics."
Sanjay Gupta is a practicing neurosurgeon and CNN's chief medical correspondent, whose book Keep Sharp translates current neuroscience research into a practical guide for maintaining brain health across a lifetime. Rather than treating cognitive decline as an inevitable consequence of aging or fixed genetics, Gupta argues that a substantial portion of brain health is within an individual's control, shaped by lifestyle factors like movement, diet, sleep, social connection, and mental stimulation. His five-pillar framework — Move, Discover, Relax, Nourish, Connect — organizes decades of research into simple, actionable categories, while directly challenging deterministic thinking about genetic risk for conditions like Alzheimer's disease. Gupta is especially direct about rejecting fear-based health messaging, arguing that durable behavior change comes from empowerment and understanding rather than scaring people into action.

The five pillars of brain health
Gupta organizes brain-health research into five actionable categories: Move, Discover, Relax, Nourish, and Connect — covering physical activity, mental stimulation, stress management, diet, and social connection.
Genetics isn't destiny
Gupta argues that regardless of DNA, factors like diet, exercise, not smoking, and limiting alcohol can meaningfully change a person's cognitive trajectory, pushing back against fatalism about genetic risk.
The brain stays enrichable at any age
Gupta emphasizes that the brain can be continuously and consistently enriched throughout life, regardless of a person's age or access to resources, countering the idea that cognitive decline is simply inevitable.
