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.
