Reading, playing a variety of games, and doing other intellectual pursuits on a daily basis over the course of a lifetime could help prevent the formation of amyloid plaques that cause Alzheimer’s disease. But for the most benefit we may need to get our brains engaged early in life - years or decades before we need memory care.

In the first study of its kind, researchers examined the amount of beta amyloid deposits in the brains of healthy seniors with no signs of dementia and found that those who reported doing daily brainy activities from the age of 6 onward had very low levels of amyloid plaque - on par with of an average person in their early 20s. Those who do not engage in intellectual activities had higher plaque levels, according to the study.

This could mean that by the time people need memory care, it may be too late to prevent further progression of Alzheimer’s.

“It was fascinating to see that those who do not have high levels of cognitive activity had high levels of these plaques,’’ said study leader Susan Landau, a research scientist at the University of California-Berkeley’s Neuroscience Institute. “We assume many of the healthy people with amyloid plaques will go on to develop Alzheimer’s later on, though the imaging technology hasn’t been around long enough to confirm this.’’

Previous research indicates that the plaque forms in areas of the brain associated with default behaviors that we do automatically, such as brushing our teeth or driving a car while we’re daydreaming.

“I think it’s a little too early to say that there is a cause and effect relationship, but the finding is intriguing,’’ Sperling said, and “I definitely think there’s enough data now to encourage’’ people to make lifestyle changes - the earlier, the better.

Researchers discovered some time ago that the kinds of learning activities most beneficial for reducing the need of memory care as we age combines physical activity, social networking, and learning a new skill.

It is also clear that there’s a genetic component involved in the need for memory care as we age. Sperling said,  “But [genes] could play a much stronger role in those who develop Alzheimer’s before age 65’’ compared with those who develop it a decade or two later.

They're often called middle-aged pauses or senior moments. One of the country's leading memory experts says that by age 45 people start having memory lapses, but you can do something about it. "People have more control than they think when it comes to their brain health," Dr. Gary Small says.

He is the director of the UCLA Longevity Center and has written "The Alzheimer's Prevention Program," which includes a simple memory-improving technique called "Look Snap Connect."


In the following video Dr. Small gives some ideas on how to prevent or hold off Alzheimer's Disease.

Right now there is no way to prevent Alzheimer's disease. The health of the body and brain depends on both lifestyle factors that are within your control.  It also depends on genetic factors.  However, new research reveals that lifestyle factors play an even more significant role in protecting the brain as we age.

In fact, a brain-healthy lifestyle, including regular exercise and a heart-healthy diet are critical elements for Alzheimer’s prevention.

Regular physical exercise reduces the risk of developing Alzheimer’s disease by 50%. Regular exercise can also slow deterioration in those who have already started to develop cognitive problems. Try for at least 30 minutes of aerobic exercise five or more times per week.

Additionally, moderate levels of weight training increase muscle mass and help maintain brain health. Combining aerobics and strength training is much better than either activity alone.

Falls and the resulting head injuries are more likely as people age, which increases the risk for Alzheimer’s disease and dementia, balance and coordination exercises like yoga and Tai Chi can help with agility and fall prevention.

Maintaining a healthy diet is important in preventing Alzheimer’s disease. A heart- and brain-healthy diet that is rich in fish, nuts, whole grains, olive oil, and lots fresh produce.

Evidence suggests that omega-3 fatty acids, such as those found in cold-water fish such as salmon, tuna, trout and sardines may help prevent Alzheimer’s disease and dementia. Fish oil supplements are also a good source for omega-3s. In addition, it’s best to reduce consumption of full-fat dairy products, red meat, fast food, fried foods, and both packaged and processed foods.
