Cerebral Palsy

I am treating a young girl with cerebral palsy.  Part of our goal is to help her be able to greet people.  Her mother told me that she received an email from her teacher reporting that the girl had a wonderful week, which was the second week of treatment.  She also said 'hi' when she came in yesterday!  Isn't it amazing that, although we may have a disorder, there are other signs and symptoms which may improve that are not necessarily related to the disorder?  Dr. Merry
