In this study, they detect a correlation between exercise and mental ability, but it is not clear which one is the cause and which one is the effect. Perhaps people with very advanced mental decline can't follow any class of exercise.

>> Our results suggest that moderate to intense exercise may help older people delay aging of the brain, but more research from randomized clinical trials comparing exercise programs to more sedentary activity is needed to confirm these results.

It could also be that factors present earlier in life influence exercise habits and cognitive decline on different time scales. For example, it's not a huge leap to imagine that some inborn deficit in neurotransmitter function could promote both of these outcomes without necessarily leading to any clinical diagnosis.
