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.

Studies show that brain-teasing computer games may ward off Alzheimer’s disease and dementia, and increase cognitive brain function. Could they eventually become a mainstay of corporate wellness programs?

For executives with their eyes on the bottom line, the thought of employees playing online video games at their desks may sound like a complete waste of time.

But studies have shown that certain games can actually improve brain power and even delay the onset of Alzheimer’s and dementia. Some argue that cognitive brain exercises may be so helpful that employers should include them as part of their corporate-wellness programs.

A recent study of 1,300 people by the Mayo Clinic found that playing computer games, reading books or doing crafts during later years led to a 30 percent to 50 percent decrease in memory loss, compared to those who did not participate in such activities.

“Aging does not need to be a passive process. By simply engaging in cognitive exercise, you can protect against future memory loss,” says study author Dr. Yonas Geda, a neuropsychiatrist at the Mayo Clinic in Rochester, Minn.
