I came across this article which was written by Stanford University while stumbling upon and found some interesting facts about dancing:
Frequent dancing apparently makes us smarter.
A major study added to the growing evidence that stimulating one's mind by dancing can ward off Alzheimer's disease and other dementia, much as physical exercise can keep the body fit. Dancing also increases cognitive acuity at all ages.
You may have heard about the New England Journal of Medicine report on the effects of recreational activities on mental acuity in aging. Here it is in a nutshell.
The 21-year study of senior citizens, 75 and older, was led by the Albert Einstein College of Medicine in New York City, funded by the National Institute on Aging, and published in the New England Journal of Medicine. Their method for objectively measuring mental acuity in aging was to monitor rates of dementia, including Alzheimer's disease.
The study wanted to see if any physical or cognitive recreational activities influenced mental acuity. They discovered that some activities had a significant beneficial effect. Other activities had none.
They studied cognitive activities such as reading books, writing for pleasure, doing crossword puzzles, playing cards and playing musical instruments. And they studied physical activities like playing tennis or golf, swimming, bicycling, dancing, walking for exercise and doing housework.
One of the surprises of the study was that almost none of the physical activities appeared to offer any protection against dementia. There can be cardiovascular benefits of course, but the focus of this study was the mind.
There was one important exception: the only physical activity to offer protection against dementia was frequent dancing.
Reading - 35% reduced risk of dementia
Bicycling and swimming - 0%
Doing crossword puzzles at least four days a week - 47%
Playing golf - 0%
Dancing frequently - 76%. That was the greatest risk reduction of any activity studied, cognitive or physical.
What could cause these significant cognitive benefits?
In this study, neurologist Dr. Robert Katzman proposed that these persons are more resistant to the effects of dementia as a result of having greater cognitive reserve and increased complexity of neuronal synapses. Like education, participation in mentally engaging activities lowers the risk of dementia by improving these neural qualities.
As Harvard Medical School psychiatrist Dr. Joseph Coyle explains in an accompanying commentary: "The cerebral cortex and hippocampus, which are critical to these activities, are remarkably plastic, and they rewire themselves based upon their use."
Our brain constantly rewires its neural pathways, as needed. If it doesn't need to, then it won't.
Aging and memory
When brain cells die and synapses weaken with aging, our nouns go first, like names of people, because there's only one neural pathway connecting to that stored information. If the single neural connection to that name fades, we lose access to it. As people age, some of them learn to parallel process, to come up with synonyms to go around these roadblocks.
The key here is Dr. Katzman's emphasis on the complexity of our neuronal synapses. More is better. Do whatever you can to create new neural paths. The opposite of this is taking the same old well-worn path over and over again, with habitual patterns of thinking and living.
When I was studying the creative process as a grad student at Stanford, I came across the perfect analogy to this:
The more stepping stones there are across the creek,
the easier it is to cross in your own style.
The focus of that aphorism was creative thinking, to find as many alternative paths as possible to a creative solution. But as we age, parallel processing becomes more critical. Now it's no longer a matter of style, it's a matter of survival — getting across the creek at all. Randomly dying brain cells are like stepping stones being removed one by one. Those who had only one well-worn path of stones are completely blocked when some are removed. But those who spent their lives trying different mental routes each time, creating a myriad of possible paths, still have several paths left.
As the study shows, we need to keep as many of those paths active as we can, while also generating new paths, to maintain the complexity of our neuronal connections.
In other words: Intelligence — use it or lose it.
What exactly do we mean by "intelligence"?
You'll probably agree that intelligence isn't just a numerical measurement, with a number of 100 plus or minus assigned to it. But what is it?
To answer this question, we go back to the most elemental questions possible. Why do animals have a brain? To survive? No, plants don't have a brain and they survive. To live longer? No, many trees outlive us.
As neuroscience educator Robert Sylwester notes, mobility is central to everything that is cognitive, whether it is physical motion or the mental movement of information. Plants have to endure whatever comes along, including predators eating them. Animals, on the other hand, can travel to seek food, shelter, mates, and to move away from unfavorable conditions. Since we can move, we need a cognitive system that can comprehend sensory input and intelligently make choices.
Semantics will differ for each of us, but according to many, if the stimulus-response relationship of a situation is automatic, we don't think of the response as requiring our intelligence. We don't use the word "intelligent" to describe a banana slug, even though it has a rudimentary brain. But when the brain evaluates several viable responses and chooses one (a real choice, not just following habits), the cognitive process is considered to be intelligent.
As Jean Piaget put it, intelligence is what we use when we don't already know what to do.
We immediately ask two questions:
Why is dancing better than other activities for improving mental capabilities?
Does this mean all kinds of dancing, or is one kind of dancing better than another?
That's where this particular study falls short. It doesn't answer these questions as a stand-alone study. Fortunately, it isn't a stand-alone study. It's one of many studies, over decades, which have shown that we increase our mental capacity by exercising our cognitive processes. Intelligence: Use it or lose it. And it's the other studies which fill in the gaps in this one. Looking at all of these studies together lets us understand the bigger picture.
The essence of intelligence is making decisions. The best advice, when it comes to improving your mental acuity, is to involve yourself in activities which require split-second rapid-fire decision making, as opposed to rote memory (retracing the same well-worn paths), or just working on your physical style.
One way to do that is to learn something new. Not just dancing, but anything new. Don't worry about the probability that you'll never
