According to neurosurgeon Sanjay Gupta, CNN checkup correspondent and author of the new script Keep Sharp : build a Better Brain at Any Age, the answer is no. Forgetfulness is convention at all ages, and your genes don ’ deoxythymidine monophosphate doom you to dementia. What ’ second crucial is taking care of your genius in the best way possible, he argues .
“ You can affect your brain ’ sulfur think and memory far more than you realize or appreciate, and the huge majority of people haven ’ triiodothyronine even begun to try, ” he writes .
Gupta distills results from hundreds of inquiry studies to help readers understand what ’ s known ( and not known ) about keeping your brain healthy. Along the way, he busts common myths—for case, that doing puzzles is a good way to ward off dementia—and replaces them with science-based advice on how to live a longer, healthier life with a more functional brain. He besides distinguishes distinctive memory lapses ( like forgetting an acquaintance ’ randomness name ) from more troublesome ones ( like not remembering the way home from a frequent destination ) —a distinction I found quite reassuring.
While he ’ mho promptly to hail the cognitive strengths of older people ( they tend to have better vocabulary skills, for example ), he besides points out that our cognitive capacities can start to decline a lot earlier in life sentence than we think, even in early adulthood. That ’ south why he recommends making life style changes immediately to improve brain at every age—not just when you hit your 60s .
Keep Sharp includes a questionnaire assess risk for cognitive decline—with some surprise questions, like “ Do you sit for most of the day ? ” or “ Do you have a history of depression ? ” Understanding your gamble can inspire you to take corrective action. To that end, here are Gupta ’ s five keys to a healthy genius .

Move more
“ When people ask me what ’ s the individual most significant thing they can do to enhance their brain ’ s function and resilience to disease, I answer with one word : exercise, ” writes Gupta. Being inactive is probably the most significant risk factor in dementia, while staying meet can help stave it off. fortunately, it doesn ’ t take much apparent motion to make a deviation : even walking for two minutes every day counts .
Exercise provides many benefits overall, including better stamina, persuasiveness, stress management, and immune officiate. But the independent reason movement helps the brain is that it reduces excitement while stimulating emergence factors that promote the function and growth of nervous cells. That ’ randomness why aerobic exercise ( more than stationary use, like weightlifting ) confers cognitive benefits —though weight-lift can build muscle .
Get enough sleep
“ Sleeping well is one of the easiest and most effective ways to improve your brain functions, a well as your ability to learn and remember new cognition, ” writes Gupta. That ’ mho because sleep seems to clear the brain of debris that might otherwise build up and create problems .
Of course, some people have trouble getting good sleep ; indeed, Gupta ’ s book reminds them of sleep hygiene principles that can help. He besides points to the importance of lie, in general, and suggests replacing day naps with stress-reducing walks in nature or meditations .
To reduce stress and rumination ( those troublesome thoughts that keep us up at night ), he recommends that people add a gratitude practice to their day—which, he writes, “ acts like a big readjust button. ” You can besides think about residential district volunteer, taking regular breaks from electronic mail and sociable media, and avoiding multitasking .
Learn, discover, and find purpose
While puzzles may not be the answer to cognitive worsen, we do need to stimulate our brains with memorize and discovery, writes Gupta. Learning creates new nervous pathways and promotes brain resiliency—something that may help stave off the outward symptoms of dementia ( like memory personnel casualty ) flush if you develop the revealing brain plaques associated with Alzheimer ’ mho .
“ Think of it as a big backing system in the brain that results from enrich life experiences such as education and occupation, ” he writes.
Building cognitive reserve doesn ’ thymine happen nightlong, he warns—it results from a life of challenging your brain through education, ferment, social relationships, and other activities. however, just because you don ’ t have a college education doesn ’ triiodothyronine average you will experience greater cognitive decline, either. Aiming to challenge your mind throughout your life is more protective than a formal degree .
Gupta warns that the majority of commercial “ brain games ” are not effective at staving off dementia, though they may improve memory, because they don ’ metric ton train problem solving or reasoning—keys to cognitive reserve. People would be better off taking a traditional class or learning a second base speech, he says, because these activities offer more complex challenges and social contact, too—also important for brain health .
Finding function in life can be good for the brain, particularly if it involves contact with people of different generations or personal learn and challenge. inquiry suggests that people with a sense of purpose have reduced risk of suffering the deleterious effects of dementia—even if their mind contains Alzheimer ’ south plaques—probably because having determination inspires them to take better concern of themselves .
Eat well
“ What ’ s good for the heart is good for the mind, ” writes Gupta. calm, there is thus much conflicting information out there about diets and dietary supplements, it can be hard to separate the wheat from the kid ( pun intended ) .
Gupta takes pains to dispel myths around gluten and alleged “ superfoods ” ( like kale and fish vegetable oil ). There is no evidence to suggest gluten affects people ’ s mind routine, he says, and kale and fish oil, while good for you, are not going to stop cognitive decline .
While it ’ south hard to recommend a perfect brain diet based on research, Gupta cites Martha Clare Morris ’ sulfur work. An epidemiologist and initiation member of the Global Council on Brain Health, Morris recommends a Mediterranean-like diet—one full-bodied in vegetables, berries, beans, whole grains, pisces, domestic fowl, and olive oil .
That diet may not be palatable or available for everyone, though. so, Gupta provides more general diet advice, besides ( using the acronym SHARP ) :
- Stay away from lots of refined sugar.
- Hydrate regularly.
- Add more omega-3 fatty acids from dietary sources (not pills).
- Reduce portions (possibly trying intermittent fasting).
- Plan ahead—meaning, have healthy snacks around so you don’t turn to junk food if you become hungry.
Connect with others
Having finale relationships with others you can count on is authoritative to a felicitous, healthy life, and may help you live longer. It ’ randomness important for genius health, besides, as research suggests its reverse, aloneness, seems to be a factor in developing Alzheimer ’ sulfur .
Gupta suggests combining socializing with other activities designed to get you moving or learning. That could mean taking a walk or class with a acquaintance, joining a team sport, or volunteering. Socializing with more diverse people or people of different generations can besides be a asset. And staying connected about, while less than ideal, may be helpful when one lives in a outside place without many sociable supports. An add bonus : Learning how to use sociable media for the first clock time may help boost memory.

While it ’ s true each of these life style factors are good for preventing cognitive decline, Gupta has advice for people already experiencing cognitive refuse, excessively. separate of his book is devoted to helping readers experiencing decline to assess where they ’ re at and figure out how to move forward from there .
For the rest of us, his book is a utilitarian and highly clear fuse for sharpening your brain at any age—not equitable to stave off dementia, but to simply enjoy your life more fully .
“ The brain can be endlessly and systematically enriched throughout our animation no matter your age or access to resources, ” he writes. If you change your life style, even a short, he promises, “ Your brain—no, your whole body—will love it. ”
