Maintain your brain: The secrets to aging success

Summary:
Aging may seem unavoidable, but that's not necessarily so when it comes to the brain. So say researchers based on counterintuitive evidence that it is what you do in old age that matters when it comes to maintaining a youthful brain rather than what you did earlier in life.

Aging may seem unavoidable, but that's not necessarily so when it comes to the brain. So say researchers in the April 27th issue of the Cell Press journal Trends in Cognitive Sciences based on counterintuitive evidence that it is what you do in old age that matters when it comes to maintaining a youthful brain rather than what you did earlier in life.

"Although some memory functions do tend to decline as we get older, several elderly show well-preserved functioning and this is related to a well-preserved, youth-like brain," says Lars Nyberg, Professor of Neuroscience at Ume University in Sweden.

Education won't save your brain -- PhDs are as likely as high school dropouts to experience memory loss with old age, the researchers say. Don't count on your job either. Those with a complex or demanding career may enjoy a limited advantage, but those benefits quickly dwindle after retirement. Engagement is the secret to success. Those who are socially, mentally and physically stimulated reliably show greater cognitive performance with a brain that appears younger than its years.

"There is quite solid evidence that staying physically and mentally active is a way towards brain maintenance," Nyberg says.

The researchers say this new take on successful aging represents an important shift in focus for the field. Much attention in the past has gone instead to understanding ways in which the brain copes with or compensates for cognitive decline in aging. The research team now argues for the importance of avoiding those age-related brain changes in the first place. Genes play a role, but life choices and other environmental factors, especially in old age, are critical.

Elderly people generally do have more trouble remembering meetings or names, Nyberg says. But those memory losses often happen later than many often think, after the age of 60. Older people also continue to accumulate knowledge and to use what they know effectively, often to very old ages.

"Taken together, a wide range of findings provides converging evidence for marked heterogeneity in brain aging," the scientists write. "Critically, some older adults show little or no brain changes relative to younger adults, along with intact cognitive performance, which supports the notion of brain maintenance. In other words, maintaining a youthful brain, rather than responding to and compensating for changes, may be the key to successful memory aging."
