"We found that high cardiovascular fitness in midlife was associated with decreased risk of dementia in a population of women followed up for up to 44 years. High compared to medium fitness decreased the risk of dementia by 88%. … High fitness delayed age at dementia onset by 9.5 years and time to dementia onset by 5 years compared to medium fitness.
Among Swedish women, a high cardiovascular fitness in midlife was associated with a decreased risk of subsequent dementia. Promotion of a high cardiovascular fitness may be included in strategies to mitigate or prevent dementia. Findings are not causal, and future research needs to focus on whether improved fitness could have positive effects on dementia risk and when during the life course a high cardiovascular fitness is most important."
