Doctors have long recommended physical exercise to reduce or delay the onset of dementia as people age. But a new study indicates that dancing may give even greater benefits than other forms of exercise.
Dr. Kathrin Rehfeld compared the effects of different kinds of exercise on volunteers with an average age of 68. Over 18 months, participants took part in either traditional fitness training with repetitive exercises like cycling or Nordic walking, or dance lessons which featured something new each week.
The study measured changes in the hippocampus, the area of the brain that is connected with learning, memory, and balance, and is affected by Alzheimer’s and similar diseases. In both groups, the hippocampus region of the brain increased. The dancers had a noticeable improvement in balance.
The dance routines varied and included jazz, square dance, line dance, and Latin. The study was published in the journal Frontiers in Human Neuroscience.
Other studies have found similar benefits to dancing:
A study at the Albert Einstein College of Medicine found that brain-stimulating activities such as reading, writing, and doing puzzles lowered the risk of dementia by 47 percent. This study did not find that regular bicycling, swimming, or team sports lowered the risk of dementia significantly. But ballroom dancing reduced the risk of developing dementia by 67 percent!
A study from Korea found that seniors who learned to dance the Cha Cha improved their memory and cognitive function over six months when compared to controls. A study from Canada found that seniors who danced the tango twice a week improved their cognitive scores.
The challenge of constantly learning a variety of new things may be one of the keys to the success of dance in improving mental ability. Dance requires a combination of mental and physical activity – dancers must remember the steps and executive them in rhythm. Also, dance is usually accompanied by music, and music has also been found to benefit people with Alzheimer’s and dementia. Music stimulates memories and positive emotions, and body response to rhythms; music can also have the effect of making people more outgoing and sociable.
