 I understand there is a lot of research going on. Is progress being made? Not sufficient progress is being made. There's research, but insufficient progress. In this century, in the 21st century, we've only had three new classes of medications approved for Parkinson's disease, and all of them only treat a subset of individuals with the disease. The most effective medicine for Parkinson's disease is called levodopa, and that was developed 50 years ago, and it doesn't treat the underlying pathology or symptoms of the disease.
