Joyce, I agree with you that everyone experiences benefit from pallidotomy. It's a bit like comparing apples and oranges sometimes when comparing benefits among patients . Many times the improvements are a very subjective and internal thing. Something that may be felt by the patient but not visible to the observer. Those improvements are equally important.
