We're looking at all those fronts. We're looking at EEG, just as we look at the EKG for the heart. We're looking at the electrical brain activity using relatively cheap devices to measure the electrical activity and getting signature patterns. We're looking at brain imaging. We're looking at genetics. We're looking at other biochemical changes and markers in addition to the clinical symptoms that are also being taken into account.
Where will we find the solutions? We don't know, as yet. I think we need to do it. We need to find it. It's very important that we do.
