CELEBRITY PROFILES FEBRUARY/MARCH 2021 BY RICHARD LALIBERTE Dr. Sanjay Gupta Gives Advice on How to Improve Brain Health CNN correspondent and neurosurgeon Sanjay Gupta advocates for be}er brain health through simple lifestyle changes. In a new book, Keep Sharp, Dr. Sanjay Gupta explores how to optimize brain health. Courtesy CNN Most people recognize Sanjay Gupta, MD, from CNN, the 24-hour news channel where he's been a medical correspondent for nearly 20 years. But he's also a practicing neurosurgeon, and in April 2003 he was asked to perform surgery in the midst of a story he was reporting. It was during the Iraq War, and Dr. Gupta was embedded with a mobile medical unit just behind the front lines. A 23-year-old Marine lieutenant, Jesus Vidana, had been shot in the head by a sniper and pronounced dead in the field. He had no pulse, but he still had a faint heartbeat when he was brought to the surgical tent, where Navy doctors recognized the value of Dr. Gupta's specialized skills. “I was asked to step back from my journalist role to look at his gunshot wound,” he later reported for CNN. “Shortly thereafter, I was removing a bullet from his brain.” Vidana recovered, and the two men—bound by an event seared into both their memories—later reconnected in the United States. Dr. Gupta, 51, has become known for such in-the-trenches reporting on wars, disasters, and epidemics. He reported from New Orleans after Hurricane Katrina in 2005, from Japan following its devastating earthquake and tsunami in 2010, from Pakistan during unprecedented flooding that same year, from Guinea during the Ebola outbreak of 2014, from Nepal after a major earthquake in 2015, and from Puerto Rico in the wake of Hurricane Maria in 2017. He's also covered a range of health-related topics, from climate change and suicide to the worldwide quest for secrets to living a longer and healthier life, and, most recently, COVID-19. On location in Afghanistan in 2011, Dr. Gupta reported on the US involvement in the conflict.

Looking back, Dr. Gupta points to the remarkable recovery of that Marine in Iraq as dramatic evidence of the brain's resilience and capacity for growth. “The biggest misconception about the brain is that it's fixed from birth—that there are only so many cells, you can't foster new connections, people are doomed to be forgetful, and cognitive decline is inevitable,” he says. “It's not inevitable. The brain is malleable and changeable, and can improve throughout our lives.” Becoming a doctor, let alone an internationally recognized one, wasn't a future Dr. Gupta envisioned while growing up near Detroit, where his parents—immigrants from India—worked as engineers at Ford Motor Company. When he was young, his interests and reading ranged widely. Then a beloved grandfather had a stroke when Sanjay was 13. While spending time at the hospital and talking to his grandfather's physicians, the teenager became fascinated with brain function. His reading turned toward medicine, and as a high school senior he was accepted into a program at the University of Michigan that allowed him to begin medical school as an undergraduate. He also enjoyed writing. Doing stories on health subjects for small magazines and newspapers quickly led to pieces for high-profile publications. Those in turn led to a fellowship at the White House, where he helped plan events and write speeches during Bill Clinton's presidency. After Dr. Gupta received his medical degree and completed his residency, he interviewed for a position at Emory; while in Atlanta, he bumped into a CNN executive he'd met during his time in Washington. The executive invited Dr. Gupta to join the network's medical news team. In 2010, Dr. Gupta met with doctors in Port-au-Prince, Haiti, after its devastating earthquake.

He also took up reporting on AIDS. That work has provided meaningful perspective on the COVID-19 pandemic, which he has covered extensively for CNN, both on television and in a podcast called Coronavirus: Fact vs. Fiction. “Journalists are going through pandemic fatigue too,” Dr. Gupta says. “I'm used to covering wars and disasters, but as terrible as those things are, they affect local populations. With COVID-19, there's nobody in the world who is not affected.” This pervasiveness can lead to a sense of despondency, he says: “We're all feeling it.” Acknowledging that we're in it together is one way to manage anxiety over COVID, he says. Another is to take action to protect yourself. “What's striking to me is that some of the most efficient tools for controlling the pandemic are tools we've known about for years,” he says of tactics like wearing masks and avoiding crowds. “They're the same tools we employed in [the flu pandemic of] 1918.” Dr. Gupta, who has covered the COVID-19 pandemic since it started in March 2020, is shown here getting his first dose of the Pfizer vaccine. Courtesy Simon & Schuster At the same time, fast-paced medical innovation that has produced multiple vaccines in less than a year is “mind-boggling,” Dr. Gupta says. He recommends getting a vaccine as soon as possible, particularly if you have a risk factor like age or a preexisting condition—advice he's given his own parents, who are in their late seventies. “They're considered vulnerable, so they're among those who should be first in line,” he says. As more than one vaccine becomes available, consult your doctor about which is best for you. “Effectiveness may vary in different populations,” Dr. Gupta says. “Be candid about your medical history, including any neurodegenerative disease, and ask, ‘How effective and safe is this vaccine for me given my specific medical history?’” Questions remain about the long-term effects of COVID-19 on people who have recovered. Viral infections, including those from measles, Zika, and previous coronaviruses, have been known to cause neurologic “after-punches” that can occur post-COVID-19 as well, Dr. Gupta says. Lingering difficulties have included brain fog, fatigue, and loss of smell or taste. “Many people with COVID-19 experience neurologic symptoms even months later, but we don't know how long they last,” Dr. Gupta says. “The longest data we have are not even a year old.” (For more about post-COVID-19 recovery, read The Long Road to COVID-19 Recovery.) He anticipates that the worst of the pandemic will occur this winter, and then it will recede. “We'll get through this,” Dr. Gupta says. “We saw that in 1918, when two years later we had the Roaring Twenties. There's a good chance that will happen here as well.” Dr. Gupta did fieldwork for his book Chasing Life, about research into health and longevity. Danielle Dellorto Building Resilience Dr. Gupta's books take a similar big-picture view of things. Both Chasing Life: New Discoveries in the Search for Immortality to Help You Age Less Today (Grand Central Life & Style, 2007) and Cheating Death: The Doctors and Medical Miracles That Are Saving Lives Against All Odds (Grand Central Life & Style, 2009) entailed wide-ranging reporting and extensive travel to investigate scientists' research into —and ordinary people's experience with—how to stay healthy and increase longevity. His new book, Keep Sharp, is about optimizing brain health. “Most adults recognize the importance of brain health but have no idea how to achieve it or even if it's possible,” Dr. Gupta says. “I wanted to show how to do it.” As he dug through the research, he came to focus on Alzheimer's disease and other forms of dementia. That's partly because they tend to dominate people's thinking about brain health, but also because he was amazed by what he discovered. “There's a lot of science around Alzheimer's and dementia that I hadn't fully appreciated,” Dr. Gupta says. One surprise was that Alzheimer's starts—often symptomless—in the brain decades earlier than is widely supposed; another was that it may be largely preventable. “I'm a brain surgeon, but Alzheimer's and neurodegenerative diseases are generally not surgical conditions,” he says. “In some ways, I was learning about prevention for the first time.” Neurologists doing research welcome Dr. Gupta's help in spreading the word. “Not only does Dr. Gupta have access to the formal data in the literature, but no researcher would decline a call from him, so he's in a position to understand what's happening,” says Steven T. DeKosky, MD, FAAN, deputy director of the McKnight Brain Institute and professor of Alzheimer's research at the University of Florida College of Medicine. Dr. Gupta identifies five main contributors to brain health that people can control: being more active, keeping the brain stimulated, getting restful sleep, nourishing the body, and having a vibrant social life. “We don't think of these measures as explicitly related to Alzheimer's but rather related to building cognitive reserve or resilience—that is, the ability of the brain to absorb some insult or injury and either fight it off or not be as impaired,” Dr.
