Earlier this year I found myself briskly walking across Helsinki to a gym where I met a small group of women in their late 60s or 70s. A physiotherapist was taking them through a workout. The walk, the workout and my earlier interview all had something in common.
I had just met a Finnish health researcher running an experiment to see whether a combination of lifestyle changes and a common diabetes drug could reduce the risk of dementia. This trial follows groundbreaking research that has shed light on the remarkable drop in the
age-adjusted rate of dementia
in recent years. Exercise, it turns out, seems to play an important role in keeping our brains healthy. So does getting
a shingles vaccine.
