I know you're passionate about this issue, but I think we have to recognize that the research that we do actually informs what is the best way, the best practices that are then used by physicians. That's what they look to. They look to finding out from research what is the best practice for them to use to identify Alzheimer's, for instance, or to identify the onset of dementia. That's what they look to us for and that is what we do to support the practical information that they need.
I can ask Dr. Alain Beaudet to perhaps speak specifically to some of these issues.
