The good news is that in Canada, close to 20 years ago, we started to work together--GPs, specialists of different types, and the Alzheimer Society of Canada, representing patients and caregivers--on one set of guidelines. And we've updated those guidelines periodically. So that's national.
As far as the basic diagnostic approach and the care goes, we have harmonization across the country. There may be variations in access to specific technologies, such as CT scans and PET scans. That is a local issue, perhaps, rather than a national guidelines issue.
The surprising inequality has been access to available drugs. And it cannot be just a question of money, because they're not expensive, considering the cost of the disease. So there is something here that we don't understand about the CDR approach, which is negative. It's like going to court. You have to prove that you're a good person. There is something wrong with the current design that you may have to look at in a broader way.
My suggestion to you, at the national level, is that maybe the approach to take would be the approach of having a patients charter. There may be something like that already in existence that we can beef up. If not, maybe we should think about it.
