Re using the brain as a preventative measure for dementia of any type---It seems increasingly clear that the more you use your brain, and the more varied ways that you use your brain, the more neural pathways you develop, and the more available routes there are to and from any one destination in the brain. So if one or a few routes get blocked or shut-down, those messages can be rerouted.
