Yes, a growing number of people under the age of 65 have early onset dementia. Approximately 50,000 people today under the age of 65 have the disease. We haven't paid enough attention to this group. There is a growing need. We have seen examples—John Mann and others—where we see it happening in the younger population. I think we are now starting to get a better hold on the actual numbers, because it's being reported more, and being recognized, as an illness. It's not a natural course of getting older that you get the disease, but we are now seeing an increase in the number of people who are younger with the disease as well.
We don't have the exact numbers. We have an idea of how many there are today, but no sense in terms of being able to project it going forward.
