Unexpectedly, Dementia Incidence Has Stabelized Or Declined

Posted on by

The incidence of dementia has been expected to substantially rise as the average life expectancy increased in high income countries. Surprisingly, two studies seem to contradict that expectation. One covering Europe shows that the rate of dementia there has stabilized, while the other study shows that the dementia rate in the US has been declining. Researchers have been unable to explain why this has been happening.

Links to articles on these studies, as well as the studies themselves, have been posted in Alzheimer’s > Epidemiology:
