Mentally stimulating activities boost brainpower in old age

New research suggests that reading books, writing and participating in brain-stimulating activities at any age may preserve memory. “Our study suggests that exercising your brain by taking part in activities such as these across a person’s lifetime, from childhood through old age, is important for brain health in old age,” said study author Robert S. Wilson, PhD, with Rush University Medical Center in Chicago.

For the study, 294 people were given tests that measured memory and thinking every year for about six years before their deaths at an average age of 89. They also answered a questionnaire about whether they read books, wrote and participated in other mentally stimulating activities during childhood, adolescence, middle age and at their current age.

After they died, their brains were examined at autopsy for evidence of the physical signs of dementia, such as lesions, brain plaques and tangles.

The research found that people who participated in mentally stimulating activities both early and late in life had a slower rate of decline in memory compared to those who did not participate in such activities across their lifetime, after adjusting for differing levels of plaques and tangles in the brain. Mental activity accounted for nearly 15 percent of the difference in decline beyond what is explained by plaques and tangles in the brain.

“Based on this, we shouldn’t underestimate the effects of everyday activities, such as reading and writing, on our children, ourselves and our parents or grandparents,” said Wilson.

The study found that the rate of decline was reduced by 32 percent in people with frequent mental activity in late life, compared to people with average mental activity, while the rate of decline of those with infrequent activity was 48 percent faster than those with average activity.

The study was supported by the National Institute on Aging and the Illinois Department of Public Health.

Mentally stimulating activities:

– Attempting to memorize a grocery list before someone goes to the store is easy and beneficial for the brain.

– A simple way to arouse the brain is by using the opposite, or non-dominant, hand.

– Getting dressed with the eyes closed, listening to music while smelling the flowers and the surrounding nature, and watching clouds while playing with modeling clay, are all simple ways to exercise the mind by using many senses at once.

– Driving a different route to work or school on a daily basis are good examples of breaking a comfortable habit.

– Even shopping at varying pharmacies and grocery stores can help stimulate the brain by breaking habits.

– Reading, learning a new language, and playing a musical instrument are all tremendous ways to stimulate the brain.

– Playing Scrabble and Sudoku are both ways to enhance cognitive ability as well.
