Pilot study by Alzheimers Australia (WA) finds regular brain exercises are the key to healthy ageing

Just two hours of brain exercises a week can markedly improve a person’s mental capacity and help fight age-related memory loss according to a recent study by Alzheimer’s Australia WA.

· Participants found improvements in their memory and were able to follow conversations better.
· Brain has the ability to change in response to new learning.
· Exercising the brain reduces the risk of developing dementia in later years.

The “Brain Fitness Pilot Project” involved people aged in their 60s, 70s and 80s from retirement villages and seniors fitness centres, taking part in a structured brain fitness program two hours per week over an eight-week period.

The program consisted of a series of computer-based hearing exercises aimed at sharpening a person’s ability to take in speech so that the brain can hear and remember more details.

While a majority of participants reported an improvement in their train of thought and could remember names and shopping lists better, another 70 percent found an improvement in their hearing and their ability to follow and remember conversations.

Alzheimer’s Australia WA Chief Executive Officer Frank Schaper said the study demonstrated that a regular program of brain exercises will reduce the impact of cognitive decline as a person grows older and can lead to healthy ageing.

Seniors may be able to slow down memory loss by exercising the brain, experts say.

Doing crossword puzzles, playing cards and other games might ward off a decline in memory or help us maintain “brainpower” as we age, reports a study by the Rush Alzheimer’s Disease Center and Rush-Presbyterian-St. Luke’s Medical Center in Chicago. The study found that more frequent participation in cognitively stimulating activities is associated with a reduced risk of Alzheimer’s Disease.

The research looked at everyday activities such as reading books, newspapers or magazines, engaging in crossword puzzles or card games, and going to museums among aging participants. The 2002 study followed more than 700 dementia-free participants age 65 and older for an average of 4.5 years. The results indicated a one-point increase in cognitive activity corresponded with a 33 percent reduction in the risk of Alzheimer’s.

“The brain is like a muscle. If you don’t use it, you lose it,” said Jim Hanekamp, founder of Glenview-based Web site www.myfitbrain.com. The Web site features a variety of cognitive games that are geared to exercising the mind.

A new study conducted by a Wheaton College professor has concluded that people that play action and puzzle games are better able to think through complex problems.

Rolf Nelson, a professor of psychology, conducted the study and published his findings in the November edition of the journal Perception. In the study, he had 20 students try to solve a spatial relation problem. The students were then given a puzzle game or action game to play. Once done with the game, the students were given the chance to finish the spatial relation problem again.

Results showed that puzzle players finished the task slower, but with more accuracy, while action players finished the task quicker but less accurately. Both groups finished quicker than if they had not played a game at all.

The goal of the study, according to the abstract from the journal:

To understand the way in which video-game play affects subsequent perception and cognitive strategy, two experiments were performed in which participants played either a fast-action game or a puzzle-solving game. Before and after video-game play, participants performed a task in which both speed and accuracy were emphasized. In experiment 1 participants engaged in a location task in which they clicked a mouse on the spot where a target had appeared, and in experiment 2 they were asked to judge which of four shapes was most similar to a target shape. In both experiments, participants were much faster but less accurate after playing the action game, while they were slower but more accurate after playing the puzzle game. Results are discussed in terms of a taxonomy of video games by their cognitive and perceptual demands.

The idea that the adult brain changes with experience was once a radical idea, but it is now well accepted that certain areas—say, the motor cortex, when learning a new physical skill—can grow new neurons or create stronger connections.

Now scientists report that the brain is even more mutable than suspected. Thanks to an unconventional research technique, neuroscientists have found the first physical proof that new experiences and information have wide-ranging effects throughout both hemispheres of the brain, rather than just creating connections in one discrete area.

“We have learned that what we call neuronal plasticity isn’t exclusive to individual synapses or even the neurons where they contact but rather occurs throughout the functional network in which synapses and neurons are embedded,” Canals says. “Those networks are absent in brain slices, so they couldn’t be studied before.”

By showing how activity in the hippocampus causes widespread changes in brain structure, Canals says the findings could explain why new memories are at first dependent on the hippocampus but can eventually be recalled without triggering that part of the brain at all.

They say you can’t teach an old dog new tricks, but scientific findings seem to indicate otherwise. Research shows that our brains literally rewire in response to new stimulation. And when it comes to computer use, Internet activity may stimulate and possibly improve brain function, according to scientists at UCLA.

“Technology may be changing our minds and changing the way we think,” said Dr. Gary Small, a neuroscientist speaking last month at the UCLA Technology & Aging Conference at the Skirball Cultural Center.

Small, director of the UCLA Center on Aging, described results of research he and colleagues performed with volunteers between the ages of 55 and 76. Half of the participants were familiar with how to search the Internet, and the other half were new to it. The participants engaged in Internet searching while simultaneously undergoing functional magnetic resonance imaging (MRI).

The MRI images clearly showed activity in the areas of the brain that control decision-making and complex reasoning — but only in the Web-savvy group. The inexperienced group showed no such activity.

However, after just five one-hour sessions of practice, the Web newbies showed activation in the same areas of the brain as the savvy group.

“Five hours on the Internet and the naive subjects had already rewired their brains,” said Small, writing about the findings in “iBrain: Surviving the Technological Alteration of the Modern Mind” (HarperCollins). “Recent studies demonstrate that older brains do remain malleable and plastic throughout life. Even areas of the brain that were reserved for specialized tasks can be recruited and retrained.”

In other words, “use it or lose it” applies to the brain. Indeed, Small notes, “Several studies have shown that exercising the brain with mental aerobics not only can improve cognitive performance scores but also may delay brain degeneration.”

Nine research teams from universities across the U.S. will study how interactive video games such as the Wii Active could help fight childhood obesity and how mobile phone games could help smokers quit or reduce tobacco use.

The teams will also focus on how video games can be designed to help people change behaviors and self-manage chronic illnesses as well as improve communication with autistic patients.

“Digital games are interactive and experiential, and so they can engage people in powerful ways to enhance learning and [change health-related behavior], especially when they are designed on the basis of well-researched strategies,” said Debra Lieberman, a communication researcher at the University of California, Santa Barbara, Institute for Social, Behavioral, and Economic Research.

Lieberman, a leading expert in the research and design of interactive media for learning and health behavior change, said the new interactive gaming studies will provide “cutting-edge, evidence-based strategies that designers will be able to use in the future to make their health games more effective.”

The nine teams, chosen from among 185 proposals, have been awarded between $100,000 and $300,000 each from $1.85 million in grant money offered by the Robert Wood Johnson Foundation.

The researchers will lead one- to two-year studies of digital games that engage players in physical activity and/or motivate them to improve how they take care of themselves through healthy changes in lifestyle, prevention behaviors, cognitive, social or physical skills, chronic disease self-management, and/or adherence to a medical treatment plan.

For example, the research teams will delve into the popular dance pad video game Dance Revolution to see how it might help Parkinson’s patients reduce the risk of falling, or how facial recognition games might be designed to help people with autism better identify others’ emotions.

The studies will focus on diverse population groups that vary by race and ethnicity, health status, income level and game-play setting, with age groups ranging from elementary school children to 80-year-olds. The research teams will study participants’ responses to health games played on a variety of platforms, such as video game consoles, computers, mobile phones and robots.

“The pace of growth and innovation in digital games is incredible, and we see tremendous potential to design them to help people stay healthy or manage chronic conditions like diabetes or Parkinson’s disease. However, we need to know more about what works and what does not, and why,” Paul Tarini, team director for the Robert Wood Johnson Foundation’s Pioneer Portfolio, said in a statement.
