What can we as foreigners do to help?

I've got a younger sister who is turning 10 in a few days. She has had tics for a pretty long time, but recently they seem to be going away slightly (although it is summer, so a lot less stress). We were told that it would most likely go away with time, but upon further research, my Mom was convinced she has mild touretts.

So, now to my question. When did you discover that you had touretts? Have there been times when it seems like it's going away, to come back?
