A study published in March in the journal Neurology suggested that women who were physically fit in middle age were roughly 88% less likely to develop dementia — defined as a decline in memory severe enough to interfere with daily life — than their peers who were only moderately fit.
Starting in 1968, neuroscientists from the University of Gothenburg in Sweden studied 191 women whose average age was 50. First, they assessed their cardiovascular health using a cycling test and grouped them into three categories: fit, moderately fit, or unfit.
Over the next four decades, the researchers regularly screened the women for dementia. In that time, 32% of the unfit women and a quarter of the moderately fit women were diagnosed with the condition, while the rate was only 5% among the fit women.
However, the research showed only a link between fitness and decreased dementia risk — it did not prove that one caused the other. Still, it builds on several other studies that suggest a powerful tie between exercise and brain health.
