Interesting to see they are rating dementia as the 7th leading cause of death[1]. In Australia the common understanding is Alzheimer's is currently the 2nd and will likely claim the 1st spot in the next decade [2].
The study seems to go against everything else I've seen which suggests that as people are living longer, the incidence are increasing, not decreasing. However, my understanding is that as we get better at curing cancers, reducing heart-disease, and generally increasing life-span, the longer a person lives, the more likely they are to get dementia.
