Dancing
It is well known that physical activity is also associated with lower risk of dementia, and Spires-Jones says that this is because it keeps the many tiny blood vessels in the brain healthy. Issues relating to the blood supply to the brain have been linked to greater rates of atrophy, or brain shrinkage, which occurs as we age.
Joyce Shaffer, a psychologist and behavioural scientist at the University of Washington, has found that dancing classes can be one of the most beneficial forms of physical activity.
“There’s the calorie burning from dancing that has an impact alone,” she says. “But because it’s a form of aerobic exercise, getting oxygen to the muscles, you have this increased supply of nutrients to the brain. This causes the brain to increase the production of a chemical called brain-derived neurotrophic factor or BDNF.”
BDNF plays an essential role in keeping neurons healthy, and the brain agile, and capable of easily forming new connections, which is the essence of memory.
“When you do aerobic exercise, your brain cells create more BDNF, which makes them healthier, and it also makes the neighbouring brain cells healthier,” says Shaffer.
