A new study reveals that adults who played a video game helped their mental agility more than adults who did crossword puzzles.
Cognitive-training games like Double Decision, are designed to improve brain functions and are at the center of a growing body of research looking at their effectiveness as scientists strive to find ways to ward off the cognitive declines that usually come with age.
A government-funded study published this month found that playing Double Decision can slow and even reverse declines in brain function associated with aging, while playing crossword puzzles cannot. The study builds on an earlier large trial which found that older people who played various cognitive games had better health-related outcomes, driving records and performed better at everyday tasks such as preparing a meal.

Rarely do you find neuroscientists, psychologists and physicians agreeing unequivocally on anything. But here’s an exception: They all say that exercise is hands down the single best thing you can do for your brain. “If we had a pill that could do what exercise does, its sales would put Viagra’s to shame,” says Laura L. Carstensen, director of the Stanford Center on Longevity and author of A Long Bright Future.
The latest research shows that people can continue to learn throughout life. Yes, brain volume shrinks slightly, and some cells die. But the brain continues to make new neurons and fine-tune their connections even very late in life.
Aerobic exercise “reduces the level of brain loss and keeps cognitive abilities sharp,” says John Medina, an affiliate professor of bioengineering at the University of Washington School of Medicine and author of Brain Rules. “It also slashes your lifetime risk of Alzheimer’s in half and your risk of general dementia by 60 percent.”

As life spans continue to lengthen, it’s becoming increasingly clear that our brains as well as our bodies are amazingly resilient and adaptive. Even 90-year-olds can build new muscle mass through physical exercise. So can their brains, although what’s being developed is not new muscle but new synapses. And while some of the exercise that produces these effects is physical, most of it is mental.
Last year, when U.S. News reported and wrote the e-book, “How to Live to 100,” expert after expert extolled the benefits of continued strenuous mental and physical exercise into and throughout old age. These are not new benefits. But what is new is the accumulating evidence for how dramatically these activities can promote healthy aging, help ward off physical and cognitive decline and illnesses, and add years to our lives.

Researchers, doctors, drug and biotech companies, and medical institutions worldwide are urgently seeking to better understand the intricacies of brain function — and particularly to develop therapies to prevent or treat diseases such as Alzheimer’s and other forms of dementia.
But despite this substantial effort, no drug or therapy can beat the powerful effect that regular physical exercise has in preventing Alzheimer’s and improving brain function — even in those with Alzheimer’s.
One Mayo Clinic study showed that those who regularly engaged in moderate exercise five or six times a week in later life reduced their risk of mild cognitive impairment by 32 percent compared with more sedentary people. Those who began exercising at midlife saw a 39 percent reduction in the risk of mild cognitive impairment.

Eating fish, chicken, olive oil and other foods rich in omega-3 fatty acids while staying away from meats and dairy — the so-called Mediterranean diet — may help older adults keep their memory and thinking skills sharp, a large new U.S. study suggests.
Using data from participants enrolled in a nationwide study on stroke, the researchers gleaned diet information from more than 17,000 white and black men and women whose average age was 64.The participants also took tests that measured their memory and thinking (cognitive) skills. During the four years of the study, 7 percent of the individuals developed problems with these skills, the researchers reported.
“Greater adherence to Mediterranean diet was associated with lower risk of incident cognitive impairment in this large population-based study,” said lead researcher Dr. Georgios Tsivgoulis, from the University of Alabama at Birmingham as well as the University of Athens, in Greece.

Fish may be the first thing that comes to mind when you think of brain food, but it’s not the only ingredient that can help keep your mind in shape. Some berries may also help improve cognitive function, according to a new study presented last weekend at the American Society for Nutrition’s Scientific Sessions & Annual Meeting in Boston.
Researchers from the Human Nutrition Research Center on Aging at Tufts University and the University of Maryland at Baltimore County fed rats a strawberry- and blueberry-based diet for two months, exposed them to radiation (which made the rats age very quickly and show signs of cognitive decline), and then looked at the neurochemical changes that occurred in their brains post-exposure.

A review of the best evidence for interventions to prevent declining brain power finds that only one – mental exercise – consistently makes a difference.
The analysis of clinical trial results for assorted drugs, supplements and activities still can’t say, however, whether the brain training programs that do seem to sharpen mental function also improve people’s daily lives or lower their risk of developing dementia.
“All we know is you will do better on certain (cognitive) tests. Whether that delays dementia…remains to be seen,” said Dr. Raza Naqvi, the study’s lead author and a researcher at the University of Toronto.
Mild cognitive impairment may affect as many as a quarter of people over age 70, according to Naqvi and his colleagues. And perhaps 10 percent of those seniors progress to more serious dementia each year, the researchers write in the Canadian Medical Association Journal.

A new study explains how cocoa compounds fight the neuronal cell death that leads to Alzheimer’s disease and dementia, on a molecular level in the brain.
It’s well established that chocolate contains pleasure-inducing and mood-enhancing chemicals, and previous studies have touted cocoa’s rich antioxidant and brain-boosting properties. Recent studies have supported the ability of chocolate compounds called flavanols to protect neuron cells against degeneration and dementia.
The new research confirms the antioxidant properties of polyphenols, the larger class of compounds that includes flavanols, and establishes how they work to protect the brain on a cellular level.

Many people believe aging is symbiotic with memory loss. The words dementia and Alzheimer’s disease weigh heavy on our hearts. We fear it will happen to us or even scarier – to our loved ones. We think if we do not talk about it, it will never become a reality or we make jokes about getting older and losing our minds to lighten the mood.
This aloof and fearful attitude stems from the belief that there is nothing we can do to improve our brain function. Although there currently isn’t a cure for memory loss you can still activate neuroplasticity (which is how the brain heals) at any age.
The acronym, B.R.A.I.N. – beliefs, relationships, activities, ignite and nutrition are five areas you can work on to slow memory loss.

It is not only our heart and waistline that benefit from lifelong exercise – our brains do too.
Undertaking physical activity four or more times a week from childhood helps improve brainpower in later life by up to a third, and could help stave off the onset of dementia.
While all adults suffer mental decline with greater age, scientists found regular exercise, such as playing sport, jogging, attending the gym or even a brisk walk with the dog, can have a protecting effect on the brain.
More than 9,000 individuals took part in a 40-year study from age of 11. Researchers quizzed them on levels of exercise at regular age intervals, and participants also undertook tests of memory, attention and learning.
