Dancing Can Reverse The Signs Of Aging In The Brain

As we grow older we suffer a decline in mental and physical fitness, which can be made worse by conditions like Alzheimer’s disease. A new study, published in the open-access journal Frontiers in Human Neuroscience, shows that older people who routinely partake in physical exercise can reverse the signs of aging in the brain, and dancing has the most profound effect.

“Exercise has the beneficial effect of slowing down or even counteracting age-related decline in mental and physical capacity,” says Dr Kathrin Rehfeld, lead author of the study, based at the German center for Neurodegenerative Diseases, Magdeburg, Germany. “In this study, we show that two different types of physical exercise (dancing and endurance training) both increase the area of the brain that declines with age. In comparison, it was only dancing that lead to noticeable behavioral changes in terms of improved balance.”

Elderly volunteers, with an average age of 68, were recruited to the study and assigned either an eighteen-month weekly course of learning dance routines, or endurance and flexibility training. Both groups showed an increase in the hippocampus region of the brain. This is important because this area can be prone to age-related decline and is affected by diseases like Alzheimer’s. It also plays a key role in memory and learning, as well as keeping one’s balance.

While previous research has shown that physical exercise can combat age-related brain decline, it is not known if one type of exercise can be better than another. To assess this, the exercise routines given to the volunteers differed. The traditional fitness training program conducted mainly repetitive exercises, such as cycling or Nordic walking, but the dance group were challenged with something new each week.

Dr Rehfeld explains, “We tried to provide our seniors in the dance group with constantly changing dance routines of different genres (Jazz, Square, Latin-American and Line Dance). Steps, arm-patterns, formations, speed and rhythms were changed every second week to keep them in a constant learning process. The most challenging aspect for them was to recall the routines under the pressure of time and without any cues from the instructor.”

These extra challenges are thought to account for the noticeable difference in balance displayed by those participants in dancing group. Dr Rehfeld and her colleagues are building on this research to trial new fitness programs that have the potential of maximizing anti-aging effects on the brain.

“Right now, we are evaluating a new system called “Jymmin” (jamming and gymnastic). This is a sensor-based system which generates sounds (melodies, rhythm) based on physical activity. We know that dementia patients react strongly when listening to music. We want to combine the promising aspects of physical activity and active music making in a feasibility study with dementia patients.”

Dr Rehfeld concludes with advice that could get us up out of our seats and dancing to our favorite beat.

“I believe that everybody would like to live an independent and healthy life, for as long as possible. Physical activity is one of the lifestyle factors that can contribute to this, counteracting several risk factors and slowing down age-related decline. I think dancing is a powerful tool to set new challenges for body and mind, especially in older age.”

This study falls into a broader collection of research investigating the cognitive and neural effects of physical and cognitive activity across the lifespan.

Anatomy Of A Dance Hit: Why We Love To Boogie With Pharrell

by Michaeleen Doucleff    May 30, 2014

There’s no doubt Pharrell’s “Happy” is the biggest hit of the year so far. It spent 15 weeks at the top of the Billboard 100 and inspired hundreds of fan videos on YouTube.

Just a few weeks ago, six Iranian teenagers for posting a video of themselves dancing to the catchy song.

So what is it about “” that triggers a nearly uncontrollable need to tap your foot, bob your head or move to the rhythm in some way?

It may be more about what’s missing from the song than what’s there.

Last month neuroscientists at Aarhus University in Denmark a study showing that danceable grooves have just the right amount of gaps or breaks in the beats. Your brain wants to fill in those gaps with body movement, says the study’s lead author, .

“Gaps in the rhythmic structure, gaps in the sort of underlying beat of the music — that sort of provides us with an opportunity to physically inhabit those gaps and fill in those gaps with our own bodies,” she says.

A few years ago, Witek set out to figure out which songs got people onto the dance floor.

She created an online survey and gave people drum patterns to listen to. Some had really simple rhythms with regular beats. Others had extremely complex rhythms, with lots of gaps where you’d expect beats to be. Finally there were drumming patterns that fell in the middle of those two extremes. They have a regular, predictable beat, but also some pauses or gaps.

Witek says that people all over the world agreed on which drum patterns made them most want to dance: “Not the ones that have very little complexity and not the ones that had very, very high complexity,” she says, “but the patterns that had a sort of a balance between predictability and complexity.”

These rhythms offer enough regularity so that we can perceive the underlying beat, Witek and her team reported in the journal PLOS ONE. But they also need enough gaps or breaks to invite participants to synchronize to the music.

So which popular songs on the radio today have this optimal amount of complexity?

“I think the recent single by Pharrell, ‘Happy,’ is a very good example,” Witek says.

The song is layered with predictable beats and complex, syncopated ones. The drums, the piano, the clapping and even Pharrell’s voice create inviting gaps, she says.

But Pharrell isn’t the only one who knows about this trick. Classic dance tunes in disco, funk, hip-hop and rhythm and blues also hit this sweet spot of , Witek says.

“Michael Jackson, Stevie Wonder — those guys have a lot of tracks which seem to have this balance between predictability and complexity when it comes to the rhythmic structure,” she says.

And don’t forget about Ray Charles. His 1950s hit “” made everybody want to hit the dance floor.

But it’s not just a song’s syncopation that gets you to go from tapping your foot in your chair to standing up and full-out dancing. It’s also the song’s layers of rhythm, says neuroscientist at McGill University.

“In ‘I’ve Got a Woman,’ the drums are keeping a very steady rhythm. The piano is syncopated and the vocals are exquisitely nuanced in time,” Levitin says. “It’s very difficult to sing along with him [Ray Charles] exactly the way he does it.”

So we don’t sing with Charles. Instead we want to move with him.

“The more rhythmically complex the music is … the easier it is to engage different body parts,” Levitin says, “because they can be synchronizing with different aspects of the music.”

So you’re swinging your shoulders with the snare drums. You’re bobbing your head with the piano. “And you might be wiggling your hips in half-time or something like that,” he says.

Before you know it, you’re up out of your chair and doing the twist.
