I can talk a little bit about the basic research side of that link.
Just as my colleague mentioned, in my lab we have had repetitive mild head injuries in the animal model, and it has definitely showed that there is a link between mild head injury and memory deficit, which means dementia.
That actually is a major research field, funded particularly in the States. We cannot access that from the department, but it is budgeted for there. In Canada, Alzheimer's, as a whole, is underfunded, and obviously this is the aspect of the research initiative that needs to be supported and funded.
