Walk, Stretch or Dance? Dancing May Be Best for the Brain – The New York Times

Could learning to dance the minuet or fandango help to protect our brains from aging?

A new study that compared the neurological effects of country dancing with those of walking and other activities suggests that there may be something unique about learning a social dance. The demands it places on the mind and body could make it unusually potent at slowing some of the changes inside our skulls that seem otherwise inevitable with aging.Neuroscientists and those in middle age or beyond know that brains alter and slow as we grow older.

Processing speed, which is a measure of how rapidly our brains can absorb, assess and respond to new information, seems to be particularly hard hit. Most people who are older than about 40 perform worse on tests of processing speed than those who are younger, with the effects accelerating as the decades pass.Scientists suspect that this decline is due in large part to a concomitant fraying of our brain’s white matter, which is its wiring.

White matter consists of specialized cells and their offshoots that pass messages between neurons and from one part of the brain to another. In young brains, these messages whip from neuron to neuron with boggling speed. But in older people, brain scans show, the white matter can be skimpier and less efficient. Messages stutter and slow.
