I know that the United Kingdom is well advanced with their dementia care research. The U.S. is a little further behind than the U.K., but I know, for instance, that they do stem cell research in the United States. I met a gentleman a couple of years ago whose wife suffers from Alzheimer's, and he actually brought her to California to have stem cell therapy. In Canada I have never come across that in my research. We have some drug trials here. There are more in other countries.
Speaking to the idea of collaboration, that's what's needed. Other countries have a better grasp, provide more home care, and provide payment for caregivers, which helps them out in keeping them at home. These are some of the strategies. Some other countries have national strategies, as I said. The U.K. is probably at the top with their dementia-friendly society and the way they care for the elderly.
