I know a little bit about this because we do have a registry component in the national population health study. In Canada, generally, registries have not been pulled together in a coordinated strategic fashion. Generally, you have a particular clinician or investigator or small group that is particularly interested, so registries pop up regionally. The work is under way now, and some of the work of the study is to both develop an inventory of those registries and also fund some demonstrations around developing best practices for building and expanding neurological registries in Canada, and also demonstrating the expansion of a particular registry from a regional focus to a more national perspective.
There's actually a call out right now, which was just released, for that work in particular. But generally speaking, registries for neurological conditions tend to be built in isolation and generally around more rare conditions. Although Alzheimer's is rare in the neurological community, it is actually one of the most prevalent conditions. Registries tend to be built around more rare conditions, such as cerebral palsy, I would suggest, or some of the neuromuscular disorders.
